Four Essential Things You Must Know About HVAC Maintenance

A properly functioning and clean HVAC system is essential to both your respiratory health and comfort. Heating and cooling system manufacturers recommend that your HVAC be inspected regularly. By having your system cleaned and calibrated, you can improve energy efficiency, keep fuel costs to a minimum, and prolong the life of your equipment.

One of the best ways to keep your heating and cooling system at its peak performance is by hiring a contractor to perform annual check-ups. A typical maintenance check-up from an expert must include the following.

General maintenance

There are certain standardized checks that every good contractor will perform on your HVAC, such as:

Checking the thermostat setting to ensure that the heating and cooling system keeps the house at a comfortable temperature,

Measuring voltage, and tightening all electrical connections to ensure safe operation and increasing life of the components,

Lubricating the moving parts: components that lack proper lubrication can create friction in motors and increase the consumption of electricity,

Checking out the condensate drain in the furnace, heat pump, and central air conditioner, a blocked drain can create water damage and upset the indoor humidity levels and

Checking system controls to ensure safe and proper operation: inspecting the starting cycle of the system can ensure that the system starts, functions, and shuts off correctly.

Heating inspection

Apart from performing some standardized tests, good contractors will also check to see if your heating system is working fine. This will include checking all oil or gas connections, burner combustion, gas pressure, and heat exchangers. Gas/Oil connections that function in an abnormal manner can be hazardous to your health. Also, a cracked heat exchanger or dirty burner can lead to improper burner operation. Both can cause the system to function less efficiently and safely.

Cooling inspection

Cooling becomes a necessity during the peak summer months. To make sure that it is perfect throughout the season, you must oversee whether the professional performs the following actions:

Clean the air conditioning and evaporator coils: dirty coils can decrease the machine’s ability to cool a house, cause the thermostat to run longer, reduce the equipment’s life and increase energy costs.

Checking the air conditioner’s refrigerant level and changing it if required: excessive or low refrigerant will make the machine less efficient, reduce its life and increase energy costs.

Cleaning and adjusting the blower components for proper system airflow: airflow problems can decrease the efficiency of the system by almost 15 percent.

Do-it-You rself HVAC Ideas

Apart from seeking expert help, you can also perform certain actions on your own to make sure that your HVAC remains in good working order, all year long. Inspect the system’s air filters and clean or change them once a month. If you don’t know how to do this, ask your contractor to show you the right way to perform the action. A dirty filter can damage your machine, and lead to increased energy costs.

Peak summer and biting winter are the busiest seasons for HVAC contractors, and so it’s best to get your cooling system checked in the spring and your heating system during the fall. Remember, you can plan to your advantage the annual maintenance around time changes during spring and fall.

Health and Safety Issues Related to HVAC

Sun, 25 May 2025 17:58:02 GMT

Health and Safety Issues Related to HVAC

Whether due to damage or improper maintenance, your HVAC unit can quickly become a health and safety hazard. Here are a few HVAC-related safety and health issues you and your family must be aware of.

Carbon monoxide poisoning

The most common safety concern of HVAC is carbon monoxide. Poisoning due to carbon monoxide can be serious, and in some cases fatal. Since carbon monoxide is odorless and colorless, it is impossible to identify until you or a loved one becomes ill. The first signs are normally like the flu —nausea, headaches, and fatigue — so they are often ignored. However, long-term exposure can be fatal and human beings with chronic health problems are specifically at risk.

A damaged heat exchanger is a common cause of carbon monoxide, particularly in older furnaces. One of the best ways to avoid poisoning is to have your unit serviced and inspected by a trained professional. You must also place a carbon monoxide detector within your house for safety purposes.

Incorrect air filtration

Bad air filtration can also be a hazard to the health of your family. Low indoor air quality — because of allergens, dust, or airborne irritants – is a common contributor to respiratory illnesses and problems. People with underlying respiratory problems such as allergies or asthma are particularly vulnerable. Several health issues can occur due to poor air quality, ranging from minor headaches to serious breathing difficulties and allergic reactions. Regular replacement and preventive maintenance of air filters is important to keep the indoor air of a home safe.

Improper humidity moisture control

This has become an important consideration for an HVAC unit. Lack of humidity during dry climates or the winter months can lead to breathing problems, dry lips, cracked skin, sore throat and other such health issues. Dry nasal passages can leave a family prone to respiratory illness and infection and can deteriorate flu symptoms. Apart from impacting your family’s safety and health, dry air also can damage your house. Cracking hardwood floors, furniture and molding are just a few expensive results of improper humidity. You can contribute to your family’s health and to the longevity of your home by installing a humidifier that regulates the moisture levels inside the house.

Electrical problems

Electrical issues can also pose several risks. A very common problem is water leakage within the system. It is very common for the condensation drain of an A/C to become blocked. This can lead to water draining onto the system’s components, leading to equipment failure, and creating the hazard of electric shock. Therefore, air conditioner restoration is not something an immature homeowner should take care of. An experienced contractor will be aware of likely risks and take the right precautions. Preventive maintenance on a regular basis is required to avoid electrical risks.

Your HVAC unit, if not properly monitored and maintained, can make you sick or further aggravate your health problems. Regular attention to air quality and professional maintenance are the best ways to avoid many safety and health risks posed by HVAC systems. However, the information provided is not meant to substitute for the medical advice and expertise of a healthcare provider. It is best to discuss any decisions about care and treatment of your medical condition with a healthcare provider.

Dangers of Badly Maintained Air Conditioners

Wed, 26 Feb 2025 18:53:05 GMT

Dangers of Badly Maintained Air Conditioners

Air conditioning systems are a valuable way of controlling the atmosphere within workplaces and houses alike. They help to maintain a temperature that is safe, healthy and comfortable. Till the time these units are properly sustained, the advantages they offer are risk-free. However, if any of the precautions are neglected, it is possible for the system to become a potential health hazard.

What are the Dangers of a Poorly Maintained Unit?

One of the biggest side effects of a badly maintained air conditioning unit is that it can spread disease causing microorganisms through air circulation. Since most houses and offices have central air conditioning, any such health hazard is spread effectively throughout the area. Contaminants and pollutants inside the system contribute to several health problems like:

Allergies

Asthma

Sinusitis

Sore throat and coughing

Fatigue

Wheezing and congestion

Flu-like illnesses

Nose, eye and throat irritation

Such issues often pop up because of poor cleaning leading to dirt, dust, and other allergic particles being carried around by circulating air. When viruses, bacteria, or fungi contaminate the air conditioning system, dangers can become more severe. A variety of illnesses can be spread or caused by lack of maintenance. Perhaps the most common disease that is spread due to problems with the A/C is Legionnaire’s disease.

The Legionella bacteria develop in temperatures between seventy to hundred Fahrenheit, making the moist, warm climate inside the A/C units an ideal ground for breeding. This disease is basically a kind of pneumonia with signs such as body aches, headache, nausea, high fever and chest pains. If not treated on time, Legionnaire can cause permanent mental or physical damage to the body. If the fever is not reduced and antibodies are ineffective, death can also occur.

The Solution

The best way of avoiding these dangers is to ensure that your system is regularly checked, well-maintained, and kept clean. Regular cleaning, particularly around outlets and intakes, is the best way to avoid problems related to asthma or allergies. Outlets and intakes are not just the easiest areas to reach, but also where allergens and dust tend to collect most. Simply averting dust build-up can go a long way in preventing the hazards.

This also involves not letting your unit sit idle. Water must keep flowing through the unit rather than keeping it stagnant, because still water gives a chance for disease-causing agents to multiply. It is also advised to keep the water at a temperature that does not allow legionella and other organisms to thrive. This means keeping the element above 140 Fahrenheit or 60 degrees centigrade or cooling it to less than 68 degrees Fahrenheit or 20 degrees centigrade.

Maintaining an A/C unit regularly can help in largely reducing health risks. Speak to an HVAC professional for details on ways to conserve your air conditioning system. Given how easy it is to have a system cleaned, it’s a very small price to pay to guard it against health issues. The effectiveness and quality of the air conditioner filters, and the health of your family are very strongly connected. Hence, it is also recommended to go for a more systematic, professional cleaning to ensure that proper hygiene is always maintained.

Advantages of a Modulating HVAC System

Wed, 11 Sep 2024 19:39:50 GMT

Advantages of a Modulating HVAC System

The HVAC industry is always on the lookout for new and innovative ways to best serve the needs of people with an eye for comfort and luxury. One such product in the air conditioning environment is the modulated scroll system. Modulated scroll systems are revolutionary air conditioning units with the latest technology that offers the features and benefits quality-conscious consumers are seeking.

Variable-speed or modulated air conditioners ensure even room temperature. Gone are the times when you used to feel that your housing is old and freezing when the air conditioner is on, or too warm when the unit gets started. These air conditioners are less expensive as the energy consumed for operation varies.

Modulated air conditioning systems help to control the indoor humidity. It is not the temperature that makes people feel hot and sweaty, it is the humidity levels that are responsible for the sultry hot feeling indoors when the air conditioner is off. This humidity, when controlled better, makes the room more comfortable.

What is Modulation?

Modulation is a technology with which it is possible to modify the performance compressor according to the changes in ambient conditions. You can eliminate swings in temperature and the RH levels of the house.

This means that the compressor capacity can be closely matched with the demand for cooling. When a modulated compressor is used in an air conditioner, it functions at a lower compression ratio, which leads to decreased energy usage.

Let’s look at some of the advantages of a modulated air conditioning system:

1. Lower energy consumption compared to standard fixed-speed compressors

2. Comfort – individual set point control can be achieved.

3. Higher system operational efficiency with total airflow.

4. Lower maintenance costs compared to other systems. All that a modulating system needs is changing the filters and cleaning the coils.

5. Controls humidity. Lower humidity allows the homeowner to raise the thermostat temperature. This saves energy and at the same time you cannot really feel a difference in the air temperature.

6. Track the load more closely, when compared with normal air conditioners, modulated air conditioning systems cycle on and off less frequently, thus increasing the amount of moisture taken out from the air.

7. Longer lasting and less intense airflow. This keeps the room at a more precise temperature and allows for better comfort and control while sleeping as the on and off cycles are fewer than a fixed speed unit.

8. Better in-home comfort and livability. These systems also provide tangible benefits as they help you sleep better, and in turn – live better.

9. Energy savings is equal to more money in the pocket. A modulated system can save more than $870 per year by way of reduced energy costs.

10. No more hot or cold spots, just even and comfortable cooling.

To sum up, when temperature and humidity control are just right, life becomes easy, and homeowners are happy. While a normal, fixed speed HVAC system only runs at full speed, the modulating system can run at two or more speeds. This provides consistent air conditioning that is simply what every home requires.

Renewable Energy Resources for HVAC

Wed, 24 Jul 2024 19:34:25 GMT

Renewable Energy Resources for HVAC

HVAC is an absolute necessity in almost every building in San Jose. Whether it is for heating, cooling, or ventilating, energy is required for the systems to do the job effectively, efficiently, and comfortably. But there’s not one system that will do the job for every facility.

Traditionally, electricity is generated from fossil fuels – coal, natural gas, and petroleum. As the demand for energy increases, the supply for it is decreasing and depleting rapidly all over the world. Plus, this energy is also responsible for the greenhouse gases that have adverse effects on the environment and are the cause for global warming that is melting glaciers and causing tsunamis.

All this has led to increased environmental awareness and the need to source energy for electricity from alternate sources and renewable sources such as wind, sun, biomass fossils. According to the reports, renewable energy is one of the most vital recently discovered resources. A report from the National Renewable Energy Laboratory (NREL), quotes, “Renewable energy resources—such as wind and solar energy are constantly replenished and will never run out.”

Renewable Energy for HVAC

For HVAC/R (heating, ventilation, air conditioning and refrigeration), solar and geo-thermal energy is most suited for heating and cooling in the residential scenarios. While most of the energy in the United States comes from fossil fuels, there is also tremendous growth in alternative and renewable energy technologies.

Solar Energy

A solar energy system produces electricity from the sun’s rays. This electricity is then used to power a building’s HVAC system . This system is made up of photovoltaic (PV) cells. The solar modules in the system harvest the energy from the sun and convert it into electricity. This is how you can use solar energy to run your HVAC units, lights, and other electrical devices.

Basically, there are two types of solar power systems. These are stand-alone and grid-connected systems. The stand-alone systems are designed in such a way that they operate independently and do not need an electric utility grid and supply certain DC or AC loads. In many such solar power systems, energy storage needs to be done through batteries.

The other type, the grid-connected power systems need an electric utility grid. These systems are designed in such a way that they are interconnected with the grid and operate parallel to the grid. These systems also use photovoltaic cells to generate energy from the sun’s rays, and this energy is stored in a grid as AC power. The electricity from this grid is supplied to the building or the household.

Geothermal HVAC

Geothermal HVAC is said to bring a household or building in harmony with the earth beneath. It takes advantage of subterranean temperatures to generate heat in winter and cool air in summer.

The temperature at the bottom of the earth’s crust is constant, typically over 1000°F. In some locations, the temperatures are so high and so close to the earth’s surface that they result in hot springs, geysers, and volcanic activity. Such places have high potential opportunities for geothermal electricity generation. Through geothermal plants, the steam is tapped and used to operate turbines which generate electricity.

A geothermal system typically consists of an indoor handling unit and a system of pipes that is buried in the earth. These pipes are called an earth loop and connected to a pump to reinject well from where the steam is tapped. The constant temperatures provide the “free” energy.

In winter, the fluid that circulates through the system’s earth loop or well absorbs the heat stored and carries it indoors. The indoor unit then compresses this heat to a higher temperature and releases it into the building, working as a heater. In summer, the geothermal system pulls out the heat from the building and transports it through the earth loop/pump to reinjection well. Here it deposits this heat into the cooler earth/aquifer. Geothermal systems do not need periodic maintenance. Once installed properly, the buried loop lasts for generations. However, filter changes and annual coil cleaning are required.

The United States Environmental Protection Agency (EPA) is expecting that some states in the US will switch to natural gas for electricity generation, according to senior agency officials on a media briefing. There are attractive discounts also available for new construction and upgradation projects.

Fix your Noisy Air Conditioners

Have you ever heard your air conditioner making peculiar sounds? If the answer is yes, then it is time for a little update on some important facts about your air conditioner.

You should start by observing the kind of sound that your air conditioner makes. Here are some types of sounds that air conditioners can make: clicking, tweeting, chirping, rattling, squealing, humming and grinding.

Are you surprised? Well, you ought to be! Especially if your air conditioner makes any of these sounds.

So, what do you need to do if your air conditioner makes noises?

Noises that come from the air conditioner can be indications that there is something seriously wrong inside.

Clicking and ticking sounds : If the air conditioner makes noise like clicking or ticking, it might indicate that some part within is not working fine. One possibility of repetitive clicking could be a problem in the system’s relay function. In such an instance, you need to call the electrician for help. Clicking or ticking sounds in the system normally relate to problems in the electrical portions. It is best mended by an electrician.

Rattling and Squealing Sounds : If your air conditioner is making sounds that resemble rattling or squealing, it could mean that there is something wrong with the outdoor fan. On the other hand, this type of sound could also mean that there is a foreign particle inside, such as a twig or a branch, leaf, or stick. These may have fallen on the outdoor unit of the air conditioner and can be the cause of these noises. Debris such as toys, rocks or mulch can also get caught inside the system and cause noise. It is best to call a technician to repair the fault. Their training and tools will help them detect the area of fault and rectify it immediately.

Tweeting or Chirping Noises : If you hear sounds from your air conditioner that resemble the chirping of birds, especially when the system is switched on after a long break, you need not worry. This type of noise is common at the beginning of a season. Since the unit has been shut for a long time, it indicates that the machine needs a bit of warming up. Of course, all the gadgets need to start working again after a long rest. However, if the sound continues persistently, and shows no sign of reducing, it is of concern. In such a case, it is best to seek professional help.

Grinding or Humming Noises : If you hear your system humming, there is every possibility that it needs lubrication. It is not uncommon for the motor in the AC unit to make a humming noise. This is no great threat to the air conditioner. Yours could be one of those units that come with unsealed motors. Such systems need to be lubricated at regular intervals. The lubrication can be in the form of SAE 10 oil that needs to be placed in the oil ports. It is a good habit to oil the air conditioner motor at the beginning of each summer.

There can be other noises from the air conditioner. A central air conditioner can be noisy when there is a problem with the condenser.

There are several ways to solve these, but it is best to call a technician to investigate the problem. However, if your unit is very old, you can replace it with a new one. Contact us 72 Degrees for more information or if you need AC maintenance or inspection.

Making Optimum Use of Natural Environment

Making Optimum Use of Natural Environment

Every country is proud of its resources. They are the backbone of the economy. Using the economy’s resources and transforming them into positive energy results in building capital stocks. These again add to the wealth for generations to come.

However, the current use, or rather misuse, of the existing resources is delivering a message, loud and clear, that there are slim chances that there will be enough resources left for future generations to use. This scenario is especially dominant in the developing countries, where access resources are plentiful, but their use is so rapid that their share of the already scarce resources is endangered.

On the other hand, there are serious consequences of our use of resources. The impacts, or rather the harmful impacts on the environment can induce damage that goes far beyond the capacity of the environment.

Let us see why our natural resources are essential.

Measuring the essentialness of a resource has different dimensions. It can mean several things. One could be that a resource might be essential for disposing of waste or processing waste. Then, a resource may be essential because it offers satisfaction to the human psyche. There are some resources that can be termed as essential because of ecological reasons.

A resource could also be essential for production. The production of oxygen, clean air, graceful surroundings, etc.

Here are some tips on how we can use natural resources to our advantage, without polluting the environment. We can save energy, reduce pollution and help in preserving the environment by proper utilization of the natural resources. The bottom line is awareness.

Planting Trees the Right Way

Trees provide multiple benefits to us. They give us shade, block the wind, prevent soil erosion, attract birds and make the air pure.

They also clean our water and make our surrounding more beautiful with their greenery.

We all know that in winter, we look for methods to avoid the chill wind from blowing indoors. And in summer, we enjoy the shade under the trees.

What we do not know that planting trees in the right direction can help save up to 30% of our energy bills.

Deciduous trees are trees that shed their leaves in winter. If we plant deciduous trees on the east and west sides of the house, the house will be cool in the summer and warm in winter.

The shade from the foliage of leaves will protect the house from the direct rays of the sun, preventing the walls from getting hot.

You will need to run the air conditioning lesser or maybe not too. Reduction in energy use means savings in terms of money.

Plus your green gas contribution also reduces and helps you fight global warming.

Planting trees and shrubs in a position where they can provide shade to the outdoor unit of the air conditioner helps in cooling the building more efficiently and reduces about 10% of our energy consumption.

Trees can be used to shade the patios, sidewalk, and driveway too. The shade will keep the concrete, yard and the surroundings cool.

If you want to block the cold winter winds, plant an evergreen conifer on the north and northwest of your house. A row of conifers will create a kind of wall to keep off the cold winter winds. This will also save heating costs up to 30%.

When the leaves of the deciduous trees fall in winter, the sun pours into your house through branches, reducing your need to keep the heater on to ward off the chillness.

How Important is Compressor Health in Air Conditioning Maintenance?

Sun, 15 Oct 2023 19:05:31 GMT

How Important is Compressor Health in Air Conditioning Maintenance?

The compressor is the most important part of the air conditioning system. This vital part is also known as the heart of the system. Just as the human heart needs to be in good condition, so is the compressor. And the compressor needs looking after to keep good health. The compressor, like the heart, depends on many other parts that relate to it. There are circuits that pass electric current and the flow of air, these are vital to the compressor just like veins in the body that run blood to the heart.

If the compressor is overworked, it will eventually wear out and stop functioning. To run efficiently, keep the compressor in tip-top condition and your air conditioning system will run smoothly and efficiently.

Here are some troubleshooting tips that will help you keep your compressor in good health.

1. Clean the coil

Make sure that the coils of the air conditioner’s compressor are clean. Dirt on the coils creates higher than normal head pressures. When this happens, heat is created, which results in warm saturated suction temperatures. Such a situation can lead to compressor failure.

2. Proper refrigerant charge

Ensure that the refrigerant charge is well maintained. There needs to be proper electrical current flowing into the compressor.

3. Prevent Oil Contamination

Remember, an oil leak can get trapped in the suction line. Oil contamination can cause oil pump failure. This is one of the ways that the compressor can fail.

4. Avoid voltage fluctuations

Electrical problems are the main cause of compressor failure and the most common is electrical failure. Ensure that there are no voltage fluctuations in the electricity system in your house. Imbalances in electrical supply result in improper voltage. This overheats the compressor, leading to its failure.

5. Avoid overheating

Overheating occurs when there is not enough suction cooling or there is lack of condenser cooling It can also occur if there is air inside the air conditioning system. This may give rise to both pressure and temperature, resulting in incorrect compressor performance.

6. Periodic maintenance

Regular checks and cleaning are the key components that will keep your compressor in good health. You can hire the services of a professional technician for periodic maintenance checks. This will also help in identifying any major repairs that the system is heading towards, well in advance. Periodic maintenance plays an important part in preserving the life of the compressor.

In addition to the tips mentioned above, it will make you a world of good to have some basic tools handy at home.

Have a megohmmeter handy as you can measure the integrity of the compressor winding insulation. Contractors suggest that this is a great diagnostic tool that alerts the HVAC owners of the potential failures that are likely soon.

Most of the causes of compressor failure can be easily avoided with little care and maintenance . All you need to do is conduct regular checks, adopt preventative maintenance measures and replace old parts with new ones as soon as they show signs of wearing. Regular maintenance ensures long compressor life and a healthy and efficient air conditioning unit.

While DIY top-up kits are also available, it would be advisable to employ a professional HVAC technician for the periodic checks and maintenance. An air conditioning specialist will also pressure-check the system to ensure that there is no environmentally toxic nitrogen gas emitted from the air conditioner. When the system is recharged with refrigerant, the required level of oil is needed to lubricate the compressor. The contractor will know how much oil is required for lubrication.

How Relative Humidity Affects Indoor Air Quality?

Mon, 14 Aug 2023 18:34:34 GMT

How Relative Humidity Affects Indoor Air Quality?

We all know that humidity is vaporized water in the air. Relative humidity refers to the percentage of water vapor in the air at a given temperature, compared with water vapor that the air can hold at that temperature. When the air at a certain temperature has all the water vapor it can hold at that temperature, the relative humidity is said to be 100%. When the relative humidity of a place is too high or too low, it can cause health problems, discomfort and generally a less hygienic atmosphere.

Indoor air quality

Environmental and energy researchers are always studying about the importance of indoor air quality. We all think healthy indoors means adequate ventilation, freshness in the air, control of pollutants and cleanliness. The list does not stop here. One important factor is the humidity levels in the rooms that can be the cause of inadequate hygiene.

The humidity of the air inside the house, if it is not maintained at optimal levels, can be a factor that has adverse effects on the health of the inmates. Maintaining the relative humidity of the air inside the house needs careful attention.

Desired humidity levels

According to reports, the human body is said to be most comfortable when the relative humidity of the area ranges between 20 and 60%. The recommended average relative humidity for your indoors is 30 to 50%, when the outside temperature is 20°F or more. If the indoor relative humidity is above 60%, mold and mildew begin to form, and these can pose quite a problem to the health of the inmates. Eventually, musty odor will start and the indoors will have a clammy feel.

On the other hand, when the relative humidity of the indoors is less than 30%, there is again the risk of health problems. Less than 30% of relative humidity can cause static electricity problems, irritation of the skin and dry eyes. The mucous membranes can start drying, which may reduce the person’s resistance towards upper respiratory illness.

It is important that the inmates perceive ambient temperature based on the relative humidity of the place. In winter, the ambient temperature would be between 69 and 78°F at a relative humidity of 30%. However, in summer, when the relative humidity is 60%, the thermostat will fall between 68 and 75°F.

Ways to improve indoor air quality

As the air remains inside the house longer, pollutants also stay longer. This kind if air infiltration differs from home to home. The air infiltration rates also change with weatherization, type of construction materials, and activities of the occupants. Infiltration rates are measured in air changes per hour (ACH), or the number of times the indoor air is replaced by outside air in an hour. The ACH rates differ from house to house and on daily basis. Usually, it is seen that older houses have ACH that averages from 1 to 2. New homes or older ones that are sealed may have an ACH of 5.

Remember, if the ACH rate is too low, the indoor air quality will be low.

Here are some tips to keep the indoor air quality high:

Open windows to provide CROSS ventilation and reduction of moisture and odors that normally rise from cooking and bathing.

Spot ventilation will help in reducing the number of pollutants emitted in a specific area and prevents their movement around the house.

Use a dehumidifier in summer and a humidifier in winter.

Use an air-to-air heat exchanger as it will mechanically ventilate and dehumidify houses in places where the climate is cold. These units can be installed as a part of your central cooling and heating systems.

Use furnace filters. These are coated with a viscous substance that allows the collection of dust, lint and fibers, preventing them from flowing into the room.

The humidity levels in San Jose are quite unpredictable. The relative humidity of this city ranges from a comfortable 38% to a very uncomfortable 98%.

Troubleshooting a Window-Mounted Air Conditioner

Mon, 10 Jul 2023 18:21:06 GMT

Troubleshooting a Window-Mounted Air Conditioner

In homes that do not have central HVAC systems, window air conditioners provide great relief especially when summer is at its peak. Window air conditioners, just like other comfort systems, are susceptible to damage, if they are not maintained well.

Maintenance and periodic cleaning are essential for all home appliances. They are the health mantras for the long, efficient, and problem-free lives of your home comfort systems. Those of you who have wall-mounted window air conditioners have a set of tasks to perform. These, if neglected, can make a hole in your pocket and cause a lot of inconvenience as well.

There are some HVAC problems that you can fix yourself. All you may need to do is some troubleshooting. If problem solving is something you would rather not do, troubleshooting will help you in narrowing down the potential problems, helping you make informed decisions about repair or replacement.

Common Problems with Window Air Conditioners:

The air conditioner does not turn on

If you experience problems when you turn on your window air conditioner, i.e. if your window air conditioner refuses to start up, check if it is receiving power. Try unplugging and plugging it again. Next, you could try plugging it in a different socket. Check the same socket with another appliance to ensure power is passing through. If you are still having problems, check your circuit breaker. If there is power, there could be problems in any of the related components in the unit, such as wiring, compressor, thermostat, selector switch or control board. Please call a professional HVAC technician to handle these.

The fan does not blow out cold air

If there is no cold air blowing out from the system, but the fan is running, you need to check if the thermostat is set correctly. If this is okay, check the compressor motor, which is situated inside the air conditioner, in the form of a small case. If the compressor makes a humming nose continuously, there could be a problem with the condenser, or the evaporator or the compressor itself. Another option is that the motor may be broken. Here again, you will need a licensed technician to fix the problem.

The air conditioner does not blow out cold enough air

If you feel that after having kept your air conditioner on for a few minutes, the air that is blowing out is not cold enough, you will first need to check the temperature of the air. This can be done with a simple thermometer. If you notice that the temperature of the air going in is 15° higher than that of the air that is blowing out, you can conclude that the unit is doing more work than it is capable of. This is not a good sign.

On the other hand, if the difference is less than 15°, check if the air damper is open. Next, check the back cover, which may have been forgotten after the winter has passed. Finally, you need to check the condensing coils. For this, remove the cover of the air conditioner and clean the coils with a soft brush.

The coils are freezing

This problem could be due to a dirty air filter. Dirt that accumulates on the air filter restricts the air flow to the evaporator coils. This reduction in the airflow makes the evaporator too cold. This causes humidity inside the room, which causes condensation and the coils freeze. When coils freeze, further problems are caused as there is reduced airflow because of the frost.

Water leaks out of the air conditioner

When you notice water at the base of the air conditioning unit, the main reason could be improper installation. You could try to tilt the system backwards a little. This will allow the water to drain away. Window air conditioners are known for water collection water at the base of the unit.

Being aware of these troubleshooting tips will help you in detecting the problem and deciding on the need to call a HVAC professional. Some of these common problems can be fixed by the average homeowner, for some a technician may be required.

Choosing the Right Thermostat - A Simple Guide

Wed, 12 Apr 2023 18:31:29 GMT

Choosing the Right Thermostat - A Simple Guide

A thermostat is a switch that is temperature-sensitive and responsible for turning your heating and cooling systems on and off. The switch recognizes the preset limit fixed and turns the air conditioner off when the indoor temperature reaches that limit. When the temperature starts rising after some time, the switch turns the air conditioner on again. This program works vice versa for heaters.

A thermostat conducts a range of operations. These could be simple manual operations or technology-based programmable units. There are different types of functionalities to offer users with enhanced and efficient operation.

Choosing a thermostat

The selection of a thermostat is easy. Recent technology has paved the way for units that are of universal compatibility. They feature product information on the package, which makes thermostats easy to understand and install. However, there are some basic rules that you need to be aware of while choosing a thermostat.

Different types of Thermostats

Based on your need and comfort requirements, you can choose a thermostat from the various options available today. But first you need to have good knowledge about the different types of thermostats.

To start off with, there are 2 basic types of thermostats – Manual Thermostats and Programmable Thermostats.

Both manual thermostats and programmable thermostats control the air conditioning. They also work on different types of furnaces that may be of gas, oil or electricity. Manual thermostats are ones that are usually found in old houses and mansions. They are typically economical units with controls that are simple and easy to operate by different people. They work efficiently, but you need to diligently set the temperature controls often. Their settings need to be changed as the temperature changes. In addition, they provide limited comfort and energy savings.

Programmable thermostats work automatically with minimum human intervention. They adjust the room temperature throughout the day without the need to set and reset the settings. They can save as much as 33% of your energy costs in heating operations and 15 to 25% energy costs in cooling operations. There are advanced models that can alternate between air conditioning and heating, especially during seasonal transitions. They feature a simple interface that is easy to operate. Some mercury-free models are also available.

Compatibility with your heating systems and air conditioners

Your thermostat needs to be compatible with your home comfort systems. You can refer to the information printed on the packaging labels to choose a thermostat that is compatible with your HVAC system. Below are a few terms with which you should be familiar to determine capability with your HVAC system.

There are thermostats with 1, 2, and multi-stage heating or cooling capabilities.

There are switches that work with direct line voltage and ones that work with 24mV. The latter is usually used with a fireplace, wall or floor furnace.

Finally, there are thermostats that are made for zoned HVAC devices. These systems feature individual controls for heating and cooling from the same HVAC system.

Thermostats to suit your lifestyle

Programmable thermostats are most suited for modern lifestyles. They can provide you with the required levels of comfort. All you need to do is set different temperatures for the various parts of the day. Their energy-saving temperature feature helps you save energy even when you are away or sleeping.

You need to select a thermostat that allows changes in settings often. While there are thermostats with preset schedules that are based on common household energy requirements, there are also thermostats that are pre-programmed and need no further setting adjustments. All that is required is plain installation.

It is important that you keep in mind the flexibility you need for your day-to-day comfort requirements. You could choose from any of these options:

7-day programming

5-2 programming

5-1-1 programming

Week-long programming

Programmable thermostats also come with a variety of controls that also allow for changing the preset program schedule when required. These have several features, including touch screen controls, backlit display panels and remote programming and control.

Houses of yesteryears – How did people keep warm

Tue, 14 Mar 2023 22:00:37 GMT

Houses of yesteryears – How did people keep warm

Can you ever imagine living without your air conditioner in summer? The first thing that flashes through your mind is, “It’s so hot. How can I live without an air conditioner?” How about the winter without a heating system in place?

People did live without air conditioning systems as close as about a hundred years ago. They lived in houses that had no HVAC systems or the technology that we have, and take for granted, today. There was no electricity to help them keep warm or cool and yet they lived comfortably and remained healthy too. Their houses were warm in winter and cool in summer.

Structure

One important thing about the houses of yesteryears is their structure. The way these houses were built speaks a lot about the ways to live comfortably in winter. The first thing is that these houses had very thick walls that helped to retain indoor warmth from seeping out. Similarly, the walls also helped to keep the cold air from entering the house.

Sometimes, homes had double walls to keep the indoors warm. It was not uncommon to see people building a concrete wall on the outside and having a wooden one inside. This double wall served as an excellent insulator.

Bricks

The bricks used in houses built a century ago were large and thick. This made the walls thick and prevented indoor air from moving out. Typically, bricks take a long time to heat and a long time to cool. Thus, in winter, when the indoors are kept warm, the bricks once warmed, do not lose their warmth quickly. This works both ways.

Natural resources

The absence of electricity was not a problem for the people of the yester years. They used natural resources to keep warm in winter. Almost every house had a large fireplace in each room and lighting a fire would be a daily ritual at dusk. Each fireplace would have sufficient logs to last the entire night. Flames from these logs would provide warmth in the room. This warmth would be absorbed with the walls, which would either be made of thick bricks or stone.

Both stone and bricks have strong energy retention properties that help keep the indoors warmer and for longer periods of time too.

Paint

People who lived in places that were cold painted their homes with dark colors. Dark colors absorb heat quicker and more efficiently than light colors. As that radiation from the sun warms that outdoors, the dark color paint absorbs that heat and retains it as these colors do not reflect sunlight as light colors do.

Glass

In the yesteryears, people used a lot of glass in the construction of houses. They would usually place large amounts of glass on or around the south side of the house. This means that the glass will be in the sunlight most time of the day. The rays of the sun would penetrate the house and warm the indoors. Radiation from the sun gets converted to heat energy that warms the entire room. The heat slowly moves further indoors and warms the entire house. The result is warmth and increased indoor temperature.

These houses usually used thick and dark curtains to prevent heat loss.

Heat retention methods

Sometimes, windows can also help in reducing heat transfer from indoors. Some houses would have cement fillings in the gap between the window frames. This would result in decreased air flow and thus heat retention.

History says that Romans had an advanced way of heating their homes. They used underfloor heating which they called hypocaust. This hypocaust would get its heat from wood fire.

Traditional Heaters are Common in Older Houses

Thu, 19 Jan 2023 18:48:32 GMT

Traditional Heaters are Common in Older Houses

While looking for a place to stay, one of the things that you need to carefully check is the type of home heating and cooling system that comes with the house or apartment. If there are any HVAC systems already installed, check their working conditions and decide if you want to continue using them. Not all residences are designed to accommodate all types of heating and cooling systems.

If the place shown by your agent is old, it is likely that there will be a traditional home heating system installed in the house. In the traditional systems, there is usually a furnace that draws air indoors and pushes it through a duct work system, which transports the air to a warming unit. Here the air is heated and then delivered back to the living area of the house. These types of heating systems usually last long, provided they have been maintained well. You could get the help of the local HVAC contractor for details on the system’s condition before deciding to move in.

72 Degrees Cooper Brothers has the highest regard for referrals for their HVAC services . In the company’s opinion, the best way to spread word about their expert services is through referrals from satisfied clients.

Lemon laws for Faulty HVAC Equipment

Mon, 25 Apr 2022 18:45:08 GMT

Lemon Laws for Faulty HVAC Equipment

Are you aware that there are laws that protect you when you are supplied with a faulty or sub-standard heating and air conditioner?

If your contractor has installed a system that needs excessive repair, or if it fails to meet the required quality standards, you can ask your contractor to replace the system with a new one. The contractor, in turn, will ask the manufacturer for the replacement. But it is not always that the manufacturer agrees to replace the home air conditioning systems.

When the manufacturer is unable to supply a defect-free product within a reasonable period, the government will grant monetary compensation. This consumer privilege is under the Lemon Law of the state. It is always advisable that you ask your HVAC contractor to give you at least a five year lemon guarantee in writing. This guarantee should cover the major components, so that in case your system ends up in a problem, according to the contract, they need to replace the defective faulty system with a new one.

A good contractor goes a long way in helping you look after your HVAC systems. We at 72 Degrees Cooper Brothers Inc., we provide air conditioning and heating repair , maintenance , and replacement services . Leave the installation and maintenance of your air conditioning, heating, and duct designing to us.

Tips on Saving Energy & Cutting Costs This Spring

Wed, 16 Mar 2022 18:21:54 GMT

Tips on Saving Energy & Cutting Costs This Spring

Fortunately, there are many ways to save energy and keep your utility bills low this spring. Cooper Bros shares some tips below.

Use a ceiling fan to cool off. If the weather is mild enough, you don’t have to rely on your air conditioner. To keep your living spaces well-ventilated and cool, you can use ceiling fans instead. Ceiling fans have a lower wattage and consume less power than AC units. They can also help keep your home at a cooler temperature and lower your electricity bills.

Have experts maintain your air conditioning unit. Keep your AC unit in optimal condition by scheduling regular inspections and maintenance. If repairs are needed, make sure to do them immediately. There are HVAC maintenance tasks that you can do yourself — for instance, cleaning or replacing the air filters. However, there are also several parts of your AC unit that are best checked and accessed by experts who have the appropriate skills and experience. HVAC units that aren’t properly tuned up can’t perform efficiently, so they tend to consume more energy.

Improve airflow and ventilation. Keep your living spaces from getting too hot by using exhaust fans and other ventilation devices. Reduce the strain on your air conditioner by making sure the warm air inside your home is properly vented out. To further improve airflow, you should place large appliances and pieces of furniture away from your vents. It may not look like it, but even how they’re arranged can affect your home’s energy efficiency and airflow — both of which can influence your HVAC system’s energy consumption and electricity bills.

Spring is a great time for HVAC maintenance and repairs, and Cooper Bros can help you with these tasks. We’re a reputable HVAC company with over 20 years of experience in the industry. To request a quote, fill out our contact form or call us at (408) 662-1538.

Air Purifiers & How They Improve Indoor Air Quality

Wed, 02 Mar 2022 19:44:52 GMT

This is a subtitle for your new post

Good indoor air quality is essential for the best living conditions. However, there are several things that can affect the quality of the air you breathe inside your home. Fortunately, air purifiers can help improve your indoor air quality.

In this article, air quality HVAC expert Cooper Bros shares some of the ways that an air purifier can help clean the air inside your home.

Prevent excess moisture and microbial growth. Moisture cannot be completely removed from any household, so keeping it at a moderate level should be your priority. Having too much moisture inside your house can affect air quality and promote microbial growth, while having too little can affect your health. For example, dry air can cause sore throats and trigger allergies. With air purifiers, you can better manage indoor humidity levels and prevent microbial growth.

Minimize dust buildup. By having an air purifier installed during your next air conditioner replacement , you can reduce dust buildup in your home and improve indoor air quality. Keep in mind that dust consists of various particles and can include pollen and even shed skin cells. These are air pollutants that can cause allergic reactions and other health risks. By installing an air purifier, the risks for allergies and respiratory illnesses will be significantly reduced.

Reduce pet dander. If you have pets at home, installing an air purifier can reduce the amount of pet dander in your home and improve your indoor air quality. Pet dander may not be an issue for your family, but if you often have guests over, it can be a health risk to them. Make sure your home is a safe place for your friends by installing an air purification system. Most HVAC systems do remove some of the dander by trapping it in the air filters, but an air purifier offers additional protection.

Cooper Bros is a leading HVAC company with over 20 years of experience. When it comes to air conditioner repair , you can trust us to handle your problem with speed and efficiency. If you’re having issues with your indoor air quality, our highly trained technicians can evaluate your home to identify specific concerns.

Best Practices of HVAC Duct Installation

Wed, 16 Feb 2022 17:55:07 GMT

Best Practices of HVAC Duct Installation

The state of your HVAC ducts that deliver heated and cooled air heavily impacts the system’s performance, energy efficiency and comfort. As such, it can only perform as well as it was installed. In this post, the leading air conditioner repair expert, Cooper Brothers, Inc, shares the best practices of HVAC duct installation .

Proper placement. As much as possible, HVAC ducts should be positioned inside the home’s conditioned envelope (the ceilings, floors and walls) to avoid exposure to the elements that will affect its performance. If your contractor needs to install the ducts outside the envelope in a basement, attic or garage, they should be protected by R-8 insulation to mitigate energy loss.

Using high-quality materials. In the past, it was standard practice to use wall cavities and ceiling joist channels to create makeshift ducts. Channeling air through these passageways is not only inefficient but will also allow pollutants and contaminants to find their way into your living space. Nowadays, reputable air conditioner replacement companies use ducts made of sheet metal, fiberglass or other flexible quality duct materials.

Ensuring balanced airflow. Balanced air pressure needs to be maintained in your home to enable your HVAC unit to operate properly and efficiently. To achieve this balance, the proper number of supply and return registers must be placed strategically to deliver and return the same amount of air in each designated room in your home.

Proper sizing and layout. To create an efficient ductwork layout, your HVAC contractor should determine your home’s heating and cooling load per room using Manual J, provided by the Air Conditioning Contractors of America. Afterwards, the equipment is handpicked using Manual S, and the duct size and layout are designed in accordance with Manual D.

Perks of Having a Whole-Home Humidifier

If you live in an area with extreme winters or a dry climate, then having a humidifier will tremendously improve your quality of life. Fortunately, you can get a whole-home humidifier for increased convenience. In today’s post, Cooper Brothers, Inc, a top air conditioner replacement company, shares the perks of having a whole-home humidifier.

Increased sleep quality

A dry throat and unhealthy respiratory system will lead to snoring, discomfort and other complications. How many times have you experienced being woken up from a deep sleep by some solid snoring? Remember that snoring can prevent others from getting a good night’s rest. Low indoor humidity will make snoring worse by drying out your palate. An indoor air humidifier will moisturize your palate, helping reduce snoring, allergies and congestion. In turn, you can get some quality rest.

An easier flu season

Doctors will tell you that dry air can draw moisture from your respiratory membranes, causing irritation. This can lead to sore throats, sinus inflammation and labored breathing. Once flu season arrives, your air conditioner repair expert will tell you that a whole-home humidifier will help you through this. A humidifier can help improve your home’s indoor air quality and keep it at ideal levels by reducing the number of pollutants in the air.

Better skin health

If you have skin issues like eczema or dermatitis, dry air can agitate it even further. A whole-home humidifier will moisturize the air inside, helping soothe your skin with natural moisture.

HVAC Corrosion 101

Wed, 02 Feb 2022 17:15:42 GMT

HVAC Corrosion 101

You might be surprised to learn that your HVAC unit is operating inefficiently. This could be due to coil corrosion, which is a serious issue. HVAC evaporator coil corrosion could either warrant a major repair or a full replacement. In this post, Cooper Brothers, Inc, the leading air conditioner replacement expert, gives you the rundown on HVAC corrosion and shares some tips for preventing it.

Causes of HVAC Corrosion

In recent years, HVAC experts have found that corroded coils occur frequently in homes in the south where home builders unknowingly used drywall imported from China. This drywall emits sulfurous gas that causes a chemical reaction when it meets the evaporator coils and wiring. As a result, the evaporator coils form pits, with corrosion shortly following.

Your air conditioner repair expert will tell you that copper corrosion can also occur when it’s exposed to formic or acetic acids, which are commonly found in household products such as cleaning solutions, adhesives, paint and plywood. You can tell if this is the case if you spot blue or black deposits on your coils. Pinhole leaks will form, and refrigerant will leak out, rendering your HVAC unit inoperable.

Corrosion Prevention Tips

It’s important to avoid products that can cause coil corrosion so that you can protect your evaporator coil, as well as your own wellbeing. As much as possible, use building materials that emit little to no volatile organic compounds (VOCs). It also helps to schedule annual inspections and HVAC cleaning to prevent coil damage. Your contractor will use a pH-balanced cleaner and a soft cloth. If there’s damage, they’ll repair it accordingly.

Troubleshooting Common Commercial Heat Pump Issues

Thu, 27 Jan 2022 17:23:37 GMT

Troubleshooting Common Commercial Heat Pump Issues

If you’re having trouble with your commercial heat pump, there are a few troubleshooting steps you can try before calling your trusted heating and air conditioning repair technician.

The Heat Pump Is Icing Up

When a heat pump ices up, this usually signals a problem with the coils. Ice buildup on the coils will prevent heat from transferring between the refrigerant and the outside air, which can impede the operation of the unit. To melt away frost, the heat pump will switch to air conditioning mode periodically. If the unit fails to defrost, the controls or sensors may be faulty, which will require attention from a technician. Icing can develop when air flow is blocked, as well. Water leaking into the unit from overflowing gutters can also cause a layer of ice to form on the exterior of the unit.

To troubleshoot the problem, melt the ice using a garden hose. It’s crucial to keep the area around the outdoor unit clear and free of debris, say heat pump and A/C repair specialists. If the gutters are leaky, call a reliable roofer to fix the issue.

The Heat Pump Is Running Constantly

A heat pump can run constantly if it’s set to an extremely low temperature during the summer. To fix this, check the thermostat and make sure it’s set to “heat”. If this isn’t the case, the unit may be too small, or the interior space may not be adequately insulated to retain the heat. However, if the temperature in the winter is warmer than mid-30s and the heat pump is still running all the time, there might be a refrigerant leak or an issue with the compressor. These scenarios will need to be addressed by a professional.

You can count on Cooper Brothers, Inc. for high-quality HVAC services , including commercial heat pump maintenance and home furnace repair .

6 Reasons Why Your Gas Furnace Is Noisy

Sat, 22 Jan 2022 17:35:43 GMT

6 Reasons Why Your Gas Furnace Is Noisy

Gas furnaces aren’t known for being quiet. If yours is making a noise tha t the blower fan doesn’t normally produce, stop using it until a professional gets to the bottom of the problem. You’ll need to turn it off, since letting a faulty furnace run can further damage its mechanical components.

What’s causing the noise? There’s no telling for sure what it is until a home furnace repair expert like Cooper Brothers digs deeper. However, here are the usual causes:

A problematic blower wheel. If you hear a scraping sound, a loose blower wheel is probably to blame. The racket originates from the friction between this component and its housing. When it’s unbalanced, you can hear loud thumps. But when the blower wheel is damaged, you’re likely to notice a banging, squealing or scratching sound instead.
A compromised motor mount . When it comes to rattling noises, most experienced furnace and AC repair technicians suspect a broken mount first. When this component fails, it causes the blower wheel to drop and hit its housing.
A loose fan belt . High-pitched squealing is your furnace’s fan belt crying for help. This is its way of telling you that it needs to be tightened or lubricated.
A bad burner . Cooper Brothers agrees that constant low rumbling is indicative of a faulty burner. Don’t use your heating unit until a technician investigates the problem.
A trapped piece of debris . If it sounds like something is stuck in your furnace’s fan, it’s probably because something is. The debris needs to be removed from your heating equipment before it causes more headaches.
An electrical issue . Lingering clicks aren’t music to anyone’s ears because they signal an electrical problem. If you don’t address it ASAP, it can necessitate a premature furnace replacement .

Stop speculating what’s behind your noisy furnace. Instead, reach out to Cooper Brothers for them to give your HVAC system a thorough checkup and uncover the problem.

3 Things That Can Drive Up Your Winter Heating Bill

Thu, 13 Jan 2022 17:45:11 GMT

3 Things That Can Drive Up Your Winter Heating Bill

An inefficient home during the winter season can drive up your heating bill significantly. Fortunately, with proper diagnosis of the root problem by a certified furnace replacement technician, you can meet your home heating needs without breaking the bank.

Below are three reasons why heating costs can get extremely high in the winter.

The insulation is insufficient or damaged.

If you notice uneven heating or skyrocketing energy costs in the winter, check your home’s insulation. Oftentimes poor insulation in the attic or walls will give way to air leaks and reduce your home’s ability to retain heat. If the insulation happens to be damp or infested with pests, a full-on replacement may be necessary. Proper insulation can be expected to reduce heating and cooling costs by up to 40 percent per year.

There are leaks in the ductwork.

A forced-air heating system can develop leaks in the ductwork, which will ultimately lead to an increase in monthly utility bills. If you suspect you have a leak in your system, let a furnace and AC repair technician fully diagnose and fix the issue. Leaky ductwork can affect indoor air quality and compromise the HVAC system, so make sure to have it repaired as soon as possible.

The furnace is outdated.

Twenty-five years is the average life of a furnace. If your equipment is old, don’t wait for a breakdown to occur before getting a new one. While replacing a furnace may come with high upfront costs, it will increase the efficiency of your home and save you money on your heating bills.

When it comes to home furnace repair and replacement , Cooper Brothers, Inc. is the team to trust. Our goal is to improve the comfort and efficiency of your home with industry-leading products and services.

Heat Pump Odors: Causes & Solutions

Mon, 27 Dec 2021 16:46:58 GMT

Heat Pump Odors: Causes & Solutions

Imagine switching on your heat pump and detecting a burning odor. What should you do? You may not need to call anyone if you can determine what’s causing the stench. If you’re still concerned because you’re not sure, switch off your heat pump and call a home furnace repair professional to come out and assess the situation.

Your heat pump could be giving off a strange odor for a variety of reasons. Here are some of the most prevalent causes for you to consider determining if one of them applies to your situation:

Burning odor. If your heat pump smells like burning plastic or rubber, you may have an electrical problem. Melting plastic on electrical lines can generate this type of odor. Electrical problems in HVAC systems can be harmful and may even result in a fire.

Musty smell. Mold is most likely forming on damp evaporator coils or in the ducting if your heat pump smells musty. Dirty sock syndrome is a term used to describe the odor of a moldy heat pump. Regular heat pump maintenance and air duct cleaning can help you avoid this issue.

Sulfurous odor. In most cases, when there’s a rotten egg smell, you most likely have a gas leak. However, your heat pump doesn’t use natural gas. If your heat pump smells like sulfur, it’s possible that a small animal died after crawling inside it for warmth. Furnace and A/C repair pros can eliminate the stench by cleaning your heat pump.

Sewer smell. As previously stated, your heat pump is electric; therefore, any rotten egg odors are likely to be caused by a gas leak elsewhere. This odor usually signals a problem with your sewer line. When your sewer line is damaged or your basement has a sewer backup, the odor will likely travel through your ductwork.

Fishy smell. If your heat pump smells like fish, it could be due to several issues, including an overheated engine, a wiring issue, melted plastic components or coatings or another technical issue. Because electrical faults are dangerous, turn off your heat pump system at the breaker box and call an HVAC specialist at once.

3 Common Causes of HVAC Heating Inefficiencies

It’s well into the cooler months of the year, and the mercury is continuing to drop. You’ve just opened your electric bill and are surprised to see an unexpected surge in power consumption. If this sounds familiar, then you’re probably dealing with an inefficient heating system.

Unfortunately, as home furnace repair experts, we see this far too often. To help you better understand what may be causing this sudden surge in usage, here we share three common problems that can lead to an inefficient heating system.

Air leaks. If your home isn’t sealed properly, then the heated air is likely going to make its way to the colder environment outside via air leaks. This will cause your heating system to work a lot harder than it needs to. To find out if this is the case for you, you can seek the help of an energy audit company to pinpoint the sources of the leaks.

Dirty air filters. There’s a reason why heater and A/C repair experts recommend that you change your air filters regularly. Not only will this contribute to better air quality, it will also help keep your HVAC system running smoothly. Clogged air filters will reduce the overall efficiency of your unit and lead to an increase in your heating bills over time.

Compromised air ducts and insulation. Another issue that can contribute to heating inefficiency is leaky air ducts and insulation. If this is the case for you, the warm air that’s being pumped by your furnace or heat pump will simply leak into your ductwork and insulation, which will decrease the efficiency of your heating system.

Whether you’re in need of simple air conditioner repair services or are looking for an experienced company to install a top-of-the-line HVAC system in your commercial building , you can count on Cooper Bros to exceed your expectations.

How Long Can I Expect My Commercial HVAC Equipment to Last?

If your commercial HVAC equipment was manufactured by a reliable company and was put in by a reputable, experienced installer, then it’s not a stretch to say that you can expect it to keep the air quality and comfort levels in your commercial space at an optimal level for many, many years. However, this doesn’t mean that you won’t eventually need to replace it when the time comes.

Although it’s hard to really say when a replacement will be due, as each case is different, we do have general expectations. Here are some of the factors that might affect your HVAC system’s lifespan.

Maintenance schedule

If you want your commercial system to last as long as advertised, then you have to give it the care and attention that it requires. Even the most expensive commercial HVAC unit in the world can’t be expected to keep chugging along without proper maintenance.

This means scheduling preventive maintenance appointments and timely repairs with a licensed heating and air conditioning repair company. Preventive maintenance mainly includes changing your filters every few months and cleaning your air ducts, as well as replacing any worn-out components.

Installation quality

A high-quality HVAC installation can also add years to your commercial system. However, this goes both ways. If the installation was done poorly, it can also significantly reduce the number of years that your unit is able to function properly. This is why it’s absolutely essential that you work with an experienced company when it comes to installation and maintenance.

Whether you’re constructing a new building from scratch or are due for an air conditioner replacement , turn to the experts at Cooper Bros for help.

Improving HVAC Airflow for Better Energy Efficiency

Mon, 18 Oct 2021 18:30:15 GMT

Improving HVAC Airflow for Better Energy Efficiency

Your HVAC system plays an integral role in ensuring consistent thermal comfort in your home. You must, therefore, check for issues that can impede the energy performance of your equipment, including poor air flow. Addressing this problem can help prevent considerable energy loss in your home. Local heating and air conditioning repair contractor Cooper Brothers, Inc. explains further below.

The Impact of Poor Airflow on Your HVAC System’s Efficiency

Your HVAC system’s performance hinges on the effective control of the path of airflow. You can be sure of consistent, comfortable temperatures in every room in your home if the conditioned air coming from the unit is smoothly directed to where it should go. Proper airflow doesn’t put your heating and cooling equipment under unnecessary stress, which means it won’t have to work too hard and consume excessive energy for your living spaces to reach the temperatures set on your thermostat.

Your HVAC system’s efficiency will be jeopardized if there’s an irregularity in the flow of air. Clogs inside the ducts and punctures and detachments at the seams or joints can lead to the following problems:

Wasted energy – It’s costly to operate an HVAC system with reduced airflow because you’ll have to pay more for the energy it consumes.

HVAC failure – An HVAC system that works too hard will most likely fail before it reaches the end of its lifespan.

Insufficient comfort – Weak air distribution from your registers is a sign of poor airflow and must be addressed immediately by your A/C repair contractor.

Top-notch HVAC Repair & Maintenance

At Cooper Brothers, Inc., we offer exceptional preventive care plans that will prolong the lifespan of your HVAC system. Expect our team of highly- trained technicians to professionally inspect, clean and tune your system to extend its lifespan and ensure its long-term performance.

Your Air Conditioning System’s Components & How They Work

Wed, 13 Oct 2021 16:43:54 GMT

Your Air Conditioning System’s Components & How They Work

Your air conditioning system’s job is to cool your indoor air during the warm months of the year. Using a thermostat, you can monitor and regulate the air temperature inside your home. The equipment also comes with a filter that removes airborne particles from the circulating air.

However, what keeps your air conditioner running is its internal components, which work together to provide consistent comfort and dehumidify your living spaces. Cooper Brothers, Inc., your trusted heat pump and furnace replacement contractor, shares a closer look at these components here:

Compressor. Located inside the outdoor unit of your air conditioner, the compressor is a large electric pump that drives the whole system to perform efficiently. It’s responsible for pumping refrigerant through the system, specifically packing molecules in the gas-based refrigerant to raise both its temperature and pressure and turn it into its liquid form.

Condenser coils. These copper coils are likewise located inside the outdoor unit of your AC equipment. They hold the refrigerant in its liquid form, which, at this point, has released the heat outdoors. An AC repair technician will make sure that these parts are in top condition to ensure efficient cooling.

Evaporator coils. Evaporator coils are also made of copper but are located inside the AC system’s air handler unit. The liquid form of the refrigerant, which becomes chilled again after releasing all the heat outdoors, moves through these coils, where it turns back into its gaseous state due to a massive pressure drop. As the air from the blower fan moves over the coils, the refrigerant removes the heat from your indoor spaces. It then moves toward the compressor, starting the process all over again.

Cooper Brothers, Inc. has a team of highly qualified professionals who’ll take care of maintaining, repairing, installing and replacing your AC system. Count on us for your other HVAC service needs, including home furnace repair and indoor air quality assessment.

Repairing vs. Replacing Your HVAC System

Thu, 30 Sep 2021 18:30:48 GMT

Repairing vs. Replacing Your HVAC System

Your HVAC system will deteriorate over time due to many contributing factors. This makes preventive maintenance highly critical, as it will help guarantee the unit’s longevity. While its failure is inevitable, homeowners need to at least be able to determine whether a repair or a replacement is best. Home furnace repair experts enlighten you more about this here.

Repairing Your HVAC System

Minor problems like loose ductwork or disconnected electrical wiring may only need a simple repair. You can make the most of repair services when the affected unit is also still under warranty. Moreover, this is the more logical option if your unit has had fewer than two repairs in the last decade.

Replacing Your HVAC System

As expected, old age is the best indication that a replacement is necessary. Any furnace replacement company will tell you that swapping out an HVAC system that’s at least two decades old with a more energy-efficient one is beneficial. You may also consider purchasing a new one if:

It’s had multiple repairs before. If your system has had at least three major repairs in recent years, then it’s probably more cost-effective to have it replaced with a brand-new unit.

You have a unit that uses Freon. Experts note that units that use Freon are less efficient and usually more expensive to repair.

The problems are substantial. If your system frequently encounters issues that involve other components such as the compressor and condenser coils, perhaps it’s time for a replacement.

Above all, it’s important not to take noticeable signs–such as increasing bills and humidity problems–for granted. Reach out to a trained professional to ensure the proper functionality of your unit.

Why Isn’t Your Thermostat Reaching the Right Temperature?

Thu, 30 Sep 2021 16:56:47 GMT

Why Isn’t Your Thermostat Reaching the Right Temperature?

If you’re currently having trouble with your thermostat not reaching the set temperature, you should understand that there could be more than one cause. We delve into each possibility in this post.

Changes to the setting

Any home furnace repair expert will tell you that this is the most common issue, one which can be corrected without having to call an HVAC technician. What you can do is some troubleshooting to make sure the temperature and fan settings are set correctly. You should also consider putting the thermostat in a spot where children don’t have casual access to it.

Wi-Fi connection issues

It’s inevitable for Wi-Fi-enabled thermostats to lose connection suddenly. When this occurs, your unit may not respond to remote commands. You can try resetting your thermostat first, then restart your router if this doesn’t work. To do this, you must unplug the power adaptor of your modem, then wait at least 10 seconds before plugging it back in. When the lights on the router come back on, try reconnecting to the Wi-Fi network.

Batteries

While thermostats will work with a battery with a low charge, they could work erratically and may completely stop responding. Furnace replacement companies suggest replacing your thermostat batteries annually.

Location of the thermostat

If your home is heated and cooled by a single unit, make certain that the thermostat is in the exact center of the house. This helps ensure that the thermostat reading stays as close to a household average as possible. It’s worth noting that only a reliable professional HVAC technician can calculate the thermostat location relative to your home’s floor plan.

Why Is Undercharging Bad for Your Air Conditioner?

Thu, 09 Sep 2021 18:47:57 GMT

Why Is Undercharging Bad for Your Air Conditioner?

A/C refrigerant changes from liquid to gas to absorb and release heat. Through this process, the warmth from inside your house is removed and your living space is cooled down. However, certain things may not fall into place as they should if your unit is undercharged, which might prompt you to call for an air conditioner repair . Here we explain more about undercharged A/Cs.

What Happens if the Refrigerant Is Low?

It should be noted that low refrigerant usually occurs due to leaks along the line or in the compressor. Since it’s likely you won’t notice anything dripping from your unit because the refrigerant evaporates as it leaks out, you’ll probably see frost forming over the indoor coils first. This is because a low level of refrigerant won’t be enough to warm up the evaporator coil, and when this happens, the remaining refrigerant will be too cold, prompting moisture to freeze on the coil.

Why Is This a Concern?

Low refrigerant levels affect your system’s cooling ability, as well as your home’s air quality . This may lead to more breakdowns and even premature failure. If you notice a rise in indoor humidity, a drop in cooling ability or a frozen evaporator coil, call a professional immediately.

Remember that the only way to avoid spending money on repairs or installing a new system is to have yours regularly inspected and recharged by a trusted air conditioning technician. Moreover, given that refrigerant is a harmful substance, licensed technicians should be the ones to do the job of first sealing up leaks in the unit’s refrigerant lines and then restoring the lost refrigerant to the system.

How to Avoid Costly Emergency HVAC Repairs

Fri, 27 Aug 2021 19:41:59 GMT

How to Avoid Costly Emergency HVAC Repairs

Commercial HVAC systems always need to be in top condition. Otherwise, work and business will likely be disrupted, leading to potential loss of resources and profits. That’s why, as a rule of thumb, you should keep your building’s HVAC system well-maintained to avoid interruptions and costly repairs.

In this post, Cooper Bros, a top-rated A/C and furnace replacement expert, shares two essential tips for preventing expensive emergency service calls.

Create a preventive maintenance program

Preventive maintenance involves regular inspections and tune-ups (at least once a year) to carry out small repairs and prevent issues from causing extensive damage to the system. So instead of waiting for your HVAC system to break down, you should have it checked regularly to stay on top of its current condition and detect any problems that may start developing. It’s highly recommended that you work with a qualified HVAC contractor and come up with a maintenance program that will help you in the long-term care of your system.

Learn how to recognize early warning signs

It’s best to perform heating or A/C repairs while the problem is still in its early stages. This way, you can get ahead of the issue and prevent it from becoming bigger over time. If you notice any of the following symptoms in your HVAC system, let your trusted contractor know immediately.

Strange odors – Unusual smells coming from your heating and cooling systems could possibly indicate a leak — which means your HVAC equipment might have some underlying issues that need immediate attention.

A/C blowing hot air or furnace giving off cool air – This is another sign that something is wrong with your HVAC system. It’s best to call your HVAC contractor for an inspection if this occurs.

HVAC unit shutting off abruptly – Of course, your HVAC equipment shouldn’t turn off by itself, so if it does, make sure to call up your local technician.

How to Reduce the Impact of Paint Fumes on Indoor Air Quality

Thu, 05 Aug 2021 21:37:34 GMT

How to Reduce the Impact of Paint Fumes on Indoor Air Quality

Many homeowners often consider painting the interior of their homes themselves. Generally, it’s best to hire professionals for this task, but if you think you’re up for the challenge, you should first consider how paint fumes can affect your home’s indoor air quality.

In this post, heating and air conditioner experts at 72 Degrees share tips on how to reduce the impact of paint fumes on indoor air quality.

Buy the right paint. You can find two types of interior paint at most local hardware stores: latex (water-based) and alkyd (oil-based). Both of these types of paint emit chemicals, but latex produces a lower amount than alkyd. Furthermore, latex paint can be cleaned up with soap and water, while alkyd paint requires a special kind of solvent.

Test for lead. If your home was built before 1978, it’s likely to have lead buried beneath the layers of paint. This can be a problem for you when the paint starts to peel or chip since it can cause the toxic chemical to be released into the air. So before stripping off the old paint and painting over your walls, call up an inspection company to test your home for lead. If lead is found to be present, you should hire an EPA-certified specialist to remove it. Much like air conditioner replacement , it would be safer to have a qualified professional perform this task.

Get rid of odors. Keep the room well-ventilated so that odors can be eliminated. Experts suggest running exhaust fans 24/7 from the start of the project until two or three days after it’s finished. Take note that harmful chemicals are released during the drying process, so to keep paint fumes from spreading to other rooms or areas of your home, make sure to cover your heating and air conditioning return openings.

Tips on How to Get the Most from Your Ductless Air Conditioner in the Summer

Thu, 05 Aug 2021 17:06:07 GMT

Tips on How to Get the Most from Your Ductless Air Conditioner in the Summer

Set the fan to auto. Each ductless air conditioner is equipped with an air handler that automatically adjusts fan speed as needed. Don’t fiddle with the fan speed: simply set it to auto. Your air conditioner will take care of the rest.

Don’t turn it off. This tip applies to all types of air conditioning systems with a thermostat. Air conditioners consume more energy upon turning them on because they must cool the entire house. While this is less of a problem with a ductless air conditioner due to the smaller space it must cool, you can nevertheless save on your energy bills if you just keep it running.

If your daily routine includes leaving the house for the day, program your thermostat to raise the room temperature by about 10 degrees, then have it return the usual temperature by the time you return. Doing this can help reduce strain on your air conditioner and the likelihood of an unexpected A/C repair .

Clean the air filter. Unlike their whole-home counterparts, ductless air conditioners come with washable user-removable air filters. This means you don’t have to buy replacement air filters for your ductless air conditioner. The user guide should have instructions on how to open the evaporator unit’s front panel, remove the filter and wash it properly. Make sure that it’s completely dry before putting it back to prevent mold growth.

Leave interior doors open to allow for airflow. If your ductless air conditioner is shared between rooms, you can achieve more efficient cooling by leaving the interior doors open to allow for airflow between the rooms. The temperature difference will be about five degrees, but this can help reduce the air conditioning workload, which can result in energy savings and improved A/C service life.

Why Do AC Evaporator & Condenser Coils Need to Match?

Thu, 22 Jul 2021 16:37:11 GMT

Why Do A/C Evaporator & Condenser Coils Need to Match?

Air conditioning systems are equipped with evaporator and condenser coils, which are respectively housed in indoor and outdoor enclosures. These coils are key components that make it possible for air conditioners to produce cool air. In today’s post, local air conditioning and furnace replacement contractor Cooper Bros discusses the importance of having matched evaporator and condenser coils.

How Do Evaporators and Condensers Work?

Air conditioners cool indoor air by putting a substance called refrigerant through various stages of compression and decompression. Refrigerant is very cold when it passes through the evaporator coils located in the indoor unit. At this stage, it does two things: it absorbs heat from the room and helps generate cool air with the aid of an air blower. The less-than-cold refrigerant is then compressed and moves on to the condenser coils. As it decompresses, it expels heat through cooling fins in the outdoor enclosure and returns to a cold state as it makes its way back to the evaporator coils.

Mismatched Evaporator and Condenser Coils

Every brand-new air conditioning unit comes with matching evaporator and condenser coils. Daily wear affects them differently. Later in their service life, the differences in their capacity become more apparent, resulting in a mismatch that causes a decline in air conditioning efficiency. The good news is that an A/C repair technician should be able to replace one or both sets of coils.

Homeowners often ask us why we don’t replace worn-out coils with higher-capacity ones to compensate for the relatively faster wear. The answer is simple: this would create a mismatch in the other direction, which doesn’t really fix the problem. It’s like replacing a car tire with one sized for a truck: not only wouldn’t the new one wear the same, it also wouldn’t work with the rest of the tires, let alone with the car. The mismatched evaporator and condenser coils would still exhibit the same problems, like a raised system workload and increased energy consumption.

Air Conditioning Myths That May Be Costing You Money

Thu, 15 Jul 2021 22:44:49 GMT

Air Conditioning Myths That May Be Costing You Money

Air conditioners are complex systems, which is why myths about them persist to this day. While most air conditioning myths are harmless, some may end up costing you money on your utility bills. In today’s post, local air quality HVAC contractor Cooper Bros shares a look at common air conditioning myths that might be costing you money.

MYTH: Fans are for cooling the room.

Running a fan along with the air conditioner creates airflow in the room. While this helps cool air get to you faster, it doesn’t cool the room. Airflow creates a greater cooling effect than just letting the heat radiate off your skin. It also enables you to turn up the thermostat a few degrees to save energy. However, there’s no benefit to keeping the fan on when nobody is in the room.

MYTH: A bigger air conditioner equals a cooler house.

“Bigger is better” applies to many things, but air conditioners are certainly not among them. An air conditioner needs to be properly sized for the house in which it’s installed. One that’s too small will redline all the time just to meet the home’s basic cooling needs. An air conditioner that’s too big will turn off and on too often, which will consume more energy. Frequent stop-starts can also result in inefficient cooling and uneven indoor humidity levels. If you’re considering an air conditioner replacement , have a certified technician first measure your home’s square footage. They can then recommend the models that are most suitable for your home’s size.

MYTH: Turning off the air conditioner when you’re away from home will save you money.

You can save a little on energy costs if you turn off your appliances when you’re not using them. However, doing so with your air conditioner will do the opposite because the air conditioner will have to cool the entire house down again when it starts back up. You’ll save on energy costs by setting a programmable thermostat to raise the temperature by about 10 degrees when the house is unoccupied and automatically lower it back down when you’re scheduled to return.

When Should You Turn Off Your Humidifier?

Mon, 28 Jun 2021 21:59:39 GMT

When Should You Turn Off Your Humidifier?

Using a humidifier during cold weather has a lot of benefits. But you might be wondering: when is the right time to turn it off?

When to Turn It Off

Your home’s humidifier may have helped you get through winter just fine, keeping your household warm and comfortable while saving you money by reducing energy costs. It probably also saved your wood furniture and floor from the effects of drying. It’s earned a rest, so you’ll want to switch it off now that the cold weather is over.

You must turn off your humidifier at the end of the heating season, as a humidifier is simply unnecessary during the warm months. Keeping it on will just cost you more money. Warm weather will make your air conditioner work harder and longer to remove the excess moisture. Your air conditioner will not be able to cool and dehumidify your home properly, and ultimately this will increase the energy costs for operating your cooling system. It’s best to look for a local AC repair professional for consultation and maintenance.

How to Turn It Off

Step 1- Turn it to the off position or the lowest percent of humidity.

Step 2- If your humidifier has duct dampers, close the bypass duct damper or turn it to the summer position.

Step 3- Turn off the water supply to the humidifier. Follow the quarter-inch water line from the humidifier. Turn the valve clockwise until it stops.

Step 4- Don’t forget to clean the humidifier. Replace the water panel and leave it to dry until winter.

What Causes Ductwork Damage?

Thu, 20 May 2021 19:55:22 GMT

What Causes Ductwork Damage?

Ductwork is an essential part of your heating, ventilation and air conditioning system. It works as the veins of the system, distributing air conditioning throughout the house. Damaged ductwork will negatively affect your home’s temperature. In this article, trusted AC repair contractor Cooper Bros discusses what causes ductwork damage.

Ductwork Damage

Damage to your ductwork will have adverse effects on your home. Damaged ducts cause excess wear and tear on your air conditioner and furnace. You’ll experience an imbalanced distribution of poor indoor air; your home’s energy efficiency will be reduced, and your utility bills will increase.

Possible Causes of Ductwork Damage

It’s important to understand the potential causes of damage to prevent it from happening. Local ductwork and furnace replacement professionals can help you identify the cause of damage.
Poor maintenance can lead to mold, dirt and particulate buildup. This won’t cause serious physical damage to your ducts, but it can lead to poor air quality in your home and consequent health problems in your household. Keep your ducts clear of any contaminants by regularly cleaning your ductwork. It’s advised that ducts should be professionally cleaned at least once every three to five years.
Small critters and insects aren’t common, but they can cause problems if left unchecked, including serious damage to your HVAC system. They can usually be detected by the noise they make as they move through the system. Smaller insects are more difficult to detect, but you can observe them as they exit around vents. Make sure to keep an eye out and resolve the problem immediately before they cause irreparable damage.

Ductwork materials will break down eventually due to old age. Most ducts last 20-25 years before damage occurs or replacement is necessary. Learn how old your ductwork is to prepare for preventive actions. If the leaks and holes are persistent due to old age, consult with local ductwork and home furnace repair professionals.

How to Reset Your Digital Thermostat

Fri, 14 May 2021 18:22:06 GMT

How to Reset Your Digital Thermostat

If you’re having trouble maintaining a comfortable temperature in your home, you might be having problems with your heating, ventilation and air conditioning system. In this post, air conditioner repair contractor Cooper Bros explains how to reset your digital thermostat.

Resetting Your Thermostat

As with other electronics, your thermostat needs to be reset occasionally, and it’s important to know when it’s necessary to do this. If adjusting the thermostat up and down isn’t working, then try resetting it. You may need to reset your thermostat after a power interruption or if it’s failing to regulate the temperature as usual.

Resetting it to its factory setting will help its programming and correct your HVAC system air quality issues. It’s best to regularly check your thermostat. This keeps you up to date on if it’s still effective at maintaining a comfortable air temperature in your home.

The Process

There are a few ways to reset your thermostat. Instructions may vary depending on the model. Most units can easily be reset by one of the following methods:

Battery backflip- This is a very quick method. You just have to install the batteries backward, wait for a few seconds, then reinstall them correctly.

Paperclip punch- This is for thermostats with a recessed reset button. Just press it in with a paperclip for five seconds, then release.

Circuit breaker flip-flop- For this method, you have to turn your thermostat to the off position, then locate the breaker for your HVAC system on your home’s circuit breaker box.

The Importance of HVAC Duct Sizing

Thu, 29 Apr 2021 22:49:23 GMT

The Importance of HVAC Duct Sizing

When professionals install a central HVAC unit for the first time, one of the most important things they spend time on is sizing the ducts that will deliver the cooled or heated air to the rooms in your house or commercial space.

Not all ducts are sized the same. Problems can occur if the size of your ducts isn’t suited for your space. Here are some of the most common issues with incorrectly sized ducts:

When the Ducts Are Too Big

Properly sized ducts enable your HVAC system to distribute air as evenly and efficiently as possible. While oversized ducts are certainly better for improving airflow, they won’t do any good if your system isn’t powerful enough. HVAC systems need specific air pressure in the ducts to do their job well. If the ducts are too big for your HVAC system, you’ll probably need a home furnace repair or even a replacement in the near future.

When the Ducts Are Too Small

If the ducts are too small, on the other hand, there might be so much pressure that it backs up into the HVAC system, causing resistance. The blower fan will have a more difficult time distributing air as well, which will reduce the efficiency of your system. This stresses out the components of the system, which can also lead to an air conditioner repair or replacement sometime soon.

Factors That Affect Sizing

There are several factors that professionals take into account when they measure to determine the size of the ducts you need for your HVAC system. Some of these factors include the following:

The size of the rooms and their individual heating and cooling needs

Insulation

Noise

Sealing

Areas where the ductwork design has to be retrofitted

It’s not advisable to attempt DIY ductwork installation. These factors have to be considered carefully, and professionals are the best people for the job.

How to Clean Your Outdoor A/C Unit

Thu, 15 Apr 2021 19:51:03 GMT

How to Clean Your Outdoor A/C Unit

Most homeowners never take the time to maintain their air conditioner. While it’s always a good idea to call a professional to perform air conditioner or home furnace repairs and regular maintenance, this doesn’t mean there’s nothing you can do yourself to keep your air conditioner in good condition. In fact, you can actually clean your heat pump or ductless mini-split system’s outdoor unit on your own.

Here’s how to do it safely:

Prepare Your Tools

You’ll need these tools to clean your outdoor unit:

Screwdriver

Shop vacuum

Garden hose

Rags

Pipe cleaner or a brush with soft bristles

Fin comb

Replacement filter

Remove Debris Around the Unit

Get rid of any leaves, branches, pine needles, etc. that have built up around your outdoor unit. These can block airflow. If there are shrubs surrounding your unit, it’s a good idea to regularly trim them so they never touch it. Keeping the area around your unit clear is one way to avoid premature air conditioner or furnace replacement .

Start Cleaning

Make sure the power to your unit is off. You can do this by flipping the breaker switch to OFF or unplugging the unit.

Use a shop vacuum to remove dust, dirt and cobwebs from around the unit and the fins.

Use your fin comb to straighten any bent fins.

Refer to your manual to find the filter. If you have a reusable filter, clean it with your garden hose using a strong spray. For disposable filters, make sure to have a replacement filter available that’s recommended for your unit.

Locate the access panel and take out the screws to remove it. Carefully place it aside and don’t get it wet.

Vacuum the condenser coils to remove dust, cobwebs and debris buildup.

Use your garden hose to clean the condenser coils after vacuuming them. Don’t use the strongest spray to avoid damaging the coils.

To clean the fan blades, use clean, damp rags.

Clean the fan vents with your vacuum and wipe away any buildup.

Let the unit dry for a few minutes. Carefully wipe surfaces dry with a clean rag.

Put the access panel back and screw it in place.

If you think the job is too challenging or time-consuming for you, call on a Cooper Brothers, Inc. maintenance or for deep cleaning.

Design Considerations for Commercial HVAC Systems

Mon, 22 Mar 2021 17:34:43 GMT

Design Considerations for Commercial HVAC Systems

The design of your commercial HVAC system is crucial, as it will impact many things in your home, from thermal comfort to indoor air quality. Moreover, to ensure the effectiveness and efficiency of your HVAC system, there are several considerations that you need to make.

In this post, home furnace repair expert Cooper Bros discusses the major factors that you should take into account when designing your commercial HVAC system.

Climate Zones

Climate zones aren’t necessary for residential homes, but in commercial buildings, having zones is a must. One reason for this is that different areas in large buildings have different heating and cooling requirements. For example, offices or rooms where workstations are located are used all the time, so these areas will need more heating and cooling than other rooms or areas that aren’t often used.

Without zones, you’re only able to set one temperature for the entire building. If you have zones, however, you can have multiple thermostats throughout the building, with each thermostat controlling the temperature in a specific zone.

Building Design

Make sure to consider the entire building when designing your HVAC system. Typically, there’s much more leeway when you’re starting from scratch, as you’re able to adjust the building design to suit heating and cooling requirements. But even if you’re renovating a building, there are still some ways for you to improve the efficiency of your HVAC system.

A/C repair can sometimes do the trick, but you can also look beyond the actual HVAC system for solutions. For example, you might want to consider adding more windows so that you can maximize natural light and heat. Adding an appropriate number of windows can lighten your heating loads during colder weather as well. To protect your building and its employees from excessive heat during the summer, experts recommend using tinted windows.

Air Distribution

Commercial buildings typically use overhead air distribution. However, since office spaces are continuously evolving and are now often designed with wide-open, high-ceiling designs, this type of air distribution may no longer be the best choice. In more open spaces, underfloor air distribution can provide more comfort, better air quality and greater energy efficiency.

Indoor Air Quality, Temperature & Your Health

Mon, 22 Feb 2021 22:55:06 GMT

Indoor Air Quality, Temperature & Your Health

Did you know that your HVAC system influences your mood and ove rall health? Indoor air quality , temperature and humidity levels all play a part in how good or bad you feel whenever you’re indoors.

Home furnace repair experts sometimes discuss the following facts when explaining why a homeowner should always keep their HVAC system clean and properly functioning.

Workplace temperature affects productivity

The Lawrence Berkeley National Laboratory Environmental Energy Technologies Division at Berkeley, CA, and the Helsinki University of Technology, Laboratory for Heating, Ventilating and Air Conditioning in Finland, determined in a study that people are most productive in a workplace with temperatures between 69.8 and 71.6 degrees. The right temperature helps workers concentrate.

Higher temperatures can increase anger

If you’re at home, it’s best to keep temperatures between 68 and 70 degrees. Anything higher than that can contribute to aggression and anger, while anything lower can lead to pent-up anger and aggression. Lethargy and sluggishness, however, can subdue these emotions. If your A/C is broken, make sure to call a pro for an A/C repair and avoid such hairy situations.

Temperature and humidity levels affect sleep quality

A good night’s sleep helps reduce a person’s tendency to be irritable, stressed or angry. Keeping your room between 62 and 67 degrees at night can help you sleep better. If the air is too dry, use a humidifier and set it to an optimal humidity level.

Indoor air quality plays a role in overall health and mood

Indoor air pollutants can cause allergic reactions. You can clean your indoor air by using an air conditioning unit with a true HEPA filter, which is more effective than a regular filter at catching air pollutants. If your A/C won’t take a HEPA filter, think about investing in an air purifier that’s properly sized for your home. It’s very important to maintain and clean your HVAC system to make sure it isn’t the cause of pollution in your home.

Should You Close Air Vents in Unused Rooms in the Winter?

Should You Close Air Vents in Unused Rooms in the Winter?

Many homeowners think it’s a good idea to close air vents in unused or infrequently used rooms during the winter months to save money on heating. Should you do the same?

The short answer is no.

As a matter of fact, doing this can lead to the need for a home furnace repair . Here’s why closing those vents during the winter season is a bad idea:

Furnaces and the ductwork that distributes warm air aren’t one-size-fits-all. They’re designed for the specific square footage of the home in which they’re installed. The distribution of air through the system is disrupted when vents are closed.

The room still has a working return air vent that pulls air out from the space. Pressure will build up if the return vent can’t get cold air. This will cause cold air to be sucked out from the gaps around the door and windows, as well as through cracks in the wall or ceiling. Your furnace then must work twice as hard as it attempts to warm the room.

Closing air vents can lead to a drastic change in the room’s temperature. This is bad for wood furniture, as it can cause warping. Ice may also start forming on the room’s windows. Moisture that gets in the gaps and crevices will freeze and expand, forcing those openings to enlarge. In addition, if the room has vinyl floors, low temperatures can cause them to crack.

Your furnace is designed to keep your entire house warm. Closing the air vents in some rooms means those rooms will have freezing temperatures that affect the entire house. This will force your furnace to work harder and longer to combat the cold coming from those rooms. This means it uses up more energy, which you’ll see on your next bill.

If the furnace breaks, you’ll be paying a lot more for an ill-timed furnace replacement. Before your furnace can be replaced, you’ll have to deal with a freezing house.

Instead of completely closing the air vents in unused rooms, you can save energy with these alternatives:

If your home has a second story, you can partially close your upstairs vents. Heat naturally rises, so your furnace can still maintain a balanced level of warmth around the house.

Close all gaps, cracks and crevices around your windows and in the walls. Hire a pro to apply caulk, sealant, weatherstripping and other weatherproofing materials.

Have your furnace maintained at least every two years to keep it working optimally. Clean and reseal the ductwork wherever necessary.

Increase the insulation in your attic and make sure the ventilation system isn’t blocked. Never cover your attic vents, as this will prevent moisture from leaving your attic, leading to water damage.

How to Use a Humidifier to Achieve a Comfortable Winter

Thu, 04 Feb 2021 16:30:07 GMT

How to Use a Humidifier to Achieve a Comfortable Winter

Heating and air conditioner repair technicians sometimes get questions from customers about humidifier use and its effects on their indoor environment. One of the most common questions is about recommended indoor humidity levels for the winter season. The guide below is useful in answering this question:

Outdoor temperature: 20-40 degrees above 0; indoor humidity =/<40%

Outdoor temperature: 10-20 degrees above 0; indoor humidity =/<35%

Outdoor temperature: 0-10 degrees above 0; indoor humidity =/<30%

Outdoor temperature: 10 degrees below 0 to 0; indoor humidity =/<25%

Outdoor temperature: 20-10 degrees below 0; indoor humidity =/<20%

Outdoor temperature: lower than 20 degrees below 0; indoor humidity =/<15%

Why You Need a Humidifier in the Winter

Many people need a humidifier to control indoor humidity levels during the winter. This is because when the air is too cold, it’s often also very dry. Cold air is incapable of carrying much moisture. To combat the ill effects of cold and dry air, a humidifier must produce optimal indoor humidity levels.

When the Air Is Too Dry

Without a humidifier, winter air can be a problem. You may have problems sleeping because the cold, dry air makes your home uncomfortable. You might also have problems with irritation, including nosebleeds and dry, itchy skin. Dry air also makes it harder for your HVAC system to make your rooms warm and comfortable. When there are problems like this with air quality , HVAC technicians are sometimes called in because the homeowner thinks there’s an issue with the heating system.

When There’s Too Much Humidity

However, if you constantly use a humidifier, this might lead to problems with condensation. This problem is typically due to a lack of attic insulation and ventilation, so when warm, moist indoor air rises into the attic, it can’t escape. This happens when temperatures rise after a deep freeze. When the warm, moist air hits the underside of the roof, which is cold, condensation forms. If there’s another cold snap, that condensation freezes and gets thicker. Another rise in temperatures will then melt it until you think your roof is leaking.

By following the guidelines above, you can prevent dry, uncomfortable air, and as well as excess humidity in your home. Make sure to have your attic inspected for adequate insulation and ventilation, also.

These Home Improvements Can Really Up Your Energy Efficiency

In addition to keeping on top of the necessary home furnace repair and air conditioning maintenance service visits, there are numerous other ways you can considerably cut your energy costs. You’ll find no shortage of tips and tricks on the internet on how to effectively improve efficiency and save money. The problem is, it’s not always clear which tips are worth giving a try and which ones won’t be helpful.

Our energy efficiency experts at Cooper Bros have classified these tips into three main categories: “Easy,” “Worth It,” and lastly, “Don’t Bother.” Here are the best ones you can try right away.

Easy Energy Efficiency

Switch your incandescent light bulbs to cooler, more efficient LED lighting. While this might not have much to do with air conditioner repair and efficiency, using LED lighting can still save you a lot of money by reducing your energy consumption. In fact, by choosing the right products, you can recover up to 80% of the initial costs in just one year and bringing this about requires nothing more than changing a light bulb.

Worth a Try

Contact your local HVAC contractor to inspect your duct network for holes and leaks. This may not be as simple as switching your bulbs, but the savings you’ll get from selling up potential leaks are worth the effort. While you’re at it, reapply any deteriorated caulks and foam around your windows and doors to further prevent air leaks.

Don’t Even Bother

Unless your windows are at the end of their lifespans, you’d be better off paying for A/C repairs and upgrades than replacing your windows. Chances are, your windows are already efficient, and whatever features new windows may advertise, they’re likely to not be as useful as simply upgrading your HVAC system.

At Cooper Bros, we’re your leading provider of HVAC services and energy efficiency upgrades.

How to Save Money on Your Heating Costs This Winter

How to Save Money on Your Heating Costs This Winter

While you may not need extensive home furnace repairs or replacements in preparation for a California winter, it’s still a good idea to make sure your system is in good shape before the temperature starts to drop. Even mild winters can put a lot of strain on heating systems like furnaces and heat pumps, so it’s important to keep on top of all your maintenance requirements to make sure you’re not surprised by sudden heating problems.

Even in relatively mild climates, wintertime can still mean a slight increase in your energy bills due to heating use. Here are a few tips from our experts at Cooper Bros on how to maximize your heating performance during this time of the year.

Don’t neglect maintenance

Ask your local heating and A/C repair company if they offer regular maintenance programs. It’s easy to forget when you should have your system tuned up for the season, but having a professional keep track of your inspection schedule can help you stay up to date on all your maintenance needs. A poorly maintained HVAC system can be a huge energy drain. Save a percentage of your monthly bills by making sure your heating is working properly before winter starts.

Clean your filters

A lot of HVAC performance issues can be mitigated just by making sure your air and furnace filters aren’t clogged. Dust and other contaminants can clutter up your filters over time, which is why experts recommend regularly cleaning or changing them at least once every 30 days.

A little cold can be good

Many furnace replacement and energy experts say that for every degree you turn your thermostat down this winter, you can save up to 1% on your energy bill. Lower temperatures during times of low use save up to 10% annually on your heating costs.

Fri, 15 Jan 2021 23:01:10 GMT

HVAC Resolutions for the New Year

The New Year is often the time when people devote themselves to some self-improvement resolutions. But as you take steps to better your life and yourself, don’t forget to look at other parts of your life and home as well. There are many ways you can improve your air quality , HVAC performance and energy efficiency just by establishing some good, helpful habits regarding your heating and cooling.

Proper care and maintenance of your HVAC system can help save you money on your energy bills, prevent expensive repairs and even prolong the life of your system. Here are some things our HVAC experts at Cooper Bros suggest can help you make better use of your air conditioning and heating system this year.

Filter changes

More often than not, most air conditioner repair jobs can be traced back to a clogged filter. Air filters must be replaced at least once every 90 days. In areas that get a lot of dust and pollution, you may even need to up your frequency to once every 30 days, or as needed. This year, mark your calendar in advance to remind yourself when to check your filter and schedule a change so you never have to suffer through low air circulation and poor performance at the times you need, you’re A/C the most.

Air and water leaks

Contact your local HVAC contractor for a thorough inspection of your system at least once every six months. This is most often done at the beginning of summer and winter. Talk to your contractor about detecting and selling any potential air leaks in your windows and doors as well to further improve the performance of your HVAC system.

Regular maintenance

Along with inspections and tune-ups, call your air conditioner replacement and repair contractor for regular maintenance visits as well. This can be done at least once every year, or for older systems, as often as needed. Sign up for a maintenance program so you never forget any important HVAC service appointments again.

This New Year, make sure your HVAC system is in good shape with the help of our professionals at Cooper Bros.

3 Telltale Signs of an HVAC Scam

Mon, 07 Dec 2020 16:20:46 GMT

3 Telltale Signs of an HVAC Scam

Opting for a cheaper, faster alternative to a home furnace repair or air conditioner replacement is very appealing when you’re feeling inconvenienced and just want to get things done. However, you could also invite possible rip-offs and scams if you’re not careful. Avoid getting caught up in a swindle by familiarizing yourself with these common signs of an HVAC scam.

They try to sell you the most expensive products. When it comes to a new furnace or air conditioner, the appropriate size and model will depend on your home and how many family members live there. If you suspect that they’re trying to push the biggest and priciest products on you, be sure to ask them why they’re recommending them in the first place. They need to complete an assessment of your home as well as perform certain calculations to properly determine what’s best for your comfort at home.

They try to rush you. If your technician is demanding an immediate decision, particularly one that costs quite a lot of money, be extra vigilant. A reliable, trustworthy company won’t try to pressure you for an answer and will instead inform you of relevant information to help you make the right decision for your home. Also, certified technicians won’t force you to buy equipment that you don’t necessarily need, especially for a simple furnace or AC repair.

They appear to be unaffiliated. Any reputable HVAC company will set a schedule for an inspection or service before showing up on your doorstep. It’s important to be aware of the specific time when a technician is scheduled to visit your home, including the reason why, so you can prepare the unit and be ready with pertinent questions that you can ask. Another sign of a potential scam is technicians appearing on the work site without uniforms or a company vehicle.

When to Replace Your Commercial HVAC System

Tue, 01 Dec 2020 18:25:30 GMT

When to Replace Your Commercial HVAC System

The condition of your commercial HVAC system is critical to the comfort and ease of the people spending time inside your building or establishment. It’s important to know when it’s the right time to replace your existing commercial HVAC system to avoid dealing with big, costly problems in the future. In this article, an air conditioner repair company shares a list of things to consider when evaluating your system.

Age

Old age is one reason you should replace your heater or air conditioner unit. If your commercial HVAC system is at least 15 years old and is starting to look like a big hunk of metal rusting away on top of your building, then it’s high time to replace it. Keep in mind that old, shabby commercial HVAC systems are significantly less efficient and more expensive to maintain than a brand-new system.

Wear & Tear

A system upgrade is long overdue by the time a unit reaches its 10th year, mostly because of the daily wear and tear it’s sustained over the years. If your commercial HVAC units have been bruised and battered due to weather conditions such as sharp-hitting hail, extreme heat from the sun and strong, high winds, it probably doesn’t heat or cool as effectively as it used to. If this is the case, be sure to call for a heater and air conditioner replacement as soon as possible.

Malfunctions

When it comes to HVAC units, a few sources of malfunctions can be easily remedied, such as blown fuses, dirty filters or motors that need oiled. Others, like a broken furnace fan or low refrigerant levels, should be left to the experts. However, if the problems your commercial HVAC system is experiencing are severe enough, it may be due for a replacement. Schedule an inspection with an air quality HVAC contractor to help you properly address these issues.

What HVAC Short Cycling Is & How to Prevent It

Fri, 27 Nov 2020 23:10:42 GMT

What HVAC Short Cycling Is & How to Prevent It

During the winter and summer months, our HVAC units work overtime to ensure that we’re comfortable throughout the season while bringing in fresh, clean air to breathe. However, if you find that your HVAC unit shuts off intermittently, then your unit is “short cycling”. This isn’t an issue that you should try to DIY, so you should leave it to your HVAC and home furnace repair professional, as they have the skills and tools to pull off the job correctly.

In this post, Cooper Brothers Inc, a top A/C repair company, shares what HVAC short cycling is, what causes it and how you can prevent it from occurring.

What Causes HVAC Short Cycling?

If your unit is short cycling, you’re heating and cooling systems must work harder than usual. As this issue persists, the internal components will start to wear out, reducing their lifespan further. Before this problem worsens, here are some signs and the underlying causes you should address immediately.

Incorrect sizing. Your A/C repair expert will tell you that one of the main causes of short cycling is that your HVAC unit is incorrectly sized for your home. This results in your HVAC unit exceeding its temperature threshold, which causes it to shut off.

Storm outages. If a storm has passed through your area, electrical issues can cause your HVAC system to shorten cycle as well if the power goes out where you’re located.

Thermostat issues. If you install yo ur thermostat in a spot that’s exposed to direct sunlight or hot appliances, this will lead to your thermostat reading the temperature incorrectly, which can cause your HVAC system to operate intermittently.

How to Prevent HVAC Short Cycling

To prevent this issue, make sure that you contact your trusted HVAC contractor to conduct a thorough inspection, during which they can spot any underlying issues that can cause HVAC short cycling. Addressing the issues early on can save you a ton of time and money and keep you feeling comfortable in the season to come.

Why Is There a Grinding Noise Coming from Your Heat Pump or Furnace?

Thu, 08 Oct 2020 17:27:35 GMT

Why Is There a Grinding Noise Coming from Your Heat Pump or Furnace?

Keeping your heating system in good shape is a year-round priority. That’s why you’ll want to keep tabs on its condition and make sure to check that there aren’t any loud grinding noises coming from your heat pump or furnace when it’s operating. But what should you do if there are? The premier furnace and AC repair company, Cooper Brothers, Inc. shares why your heat pump or furnace is making grinding noises here and how you can deal with them.

On Heat Pumps

The loud, worrisome sound you’re hearing may indicate compressor problems. This component serves as the core of your heat pump, and when the compressor is worn out, it creates a metallic grinding noise. This usually means this component will need to be entirely replaced to ensure your heat pump can deliver the reliable heating performance you’ve come to expect.

Loose or damaged blower fan belts also generate these grinding noises. This occurs when the loose belt rubs up against the other components within the system. When overlooked, the belt can damage these other parts and negatively affect the way your heat pump functions. You want to avoid this, of course, so have the unit checked immediately by a trusted heat pump and home furnace repair company like Cooper Brothers, Inc., who’ll assess the severity of the issue and provide the appropriate fix.

On the Furnace

One typical reason for grinding noises in the furnace is a busted blower wheel. It may have become loose from the motor wheel; in which case you’ll need a professional HVAC technician to tighten the wheel. The blower wheel might be broken instead, which will require a quick replacement, or perhaps the motor mount has been damaged, causing the whole blower assembly to drop and hit the housing. Whatever the case, once you hear a metallic grinding noise, turn the heating system off promptly and consult a reliable HVAC company for the necessary solution.

In this area, that would be the leading furnace replacement and repair company, Cooper Brothers, Inc. With our unmatched workmanship and decades of industry experience, we’ll restore your heating system to exceptional condition and extend its service life. Our service areas include the cities in and around San Jose, CA.

What Causes Your A/C to Leak Water Inside Your Home?

Thu, 20 Aug 2020 18:28:45 GMT

What Causes Your AC to Leak Water Inside Your Home?

If there’s one thing an air conditioner shouldn’t do, it’s to leak water inside the house. This HVAC problem usually occurs in the months when cooling is required, and when it does come up, the first thing you need to do is turn off your air conditioner’s thermostat.

Keep on reading to learn what can cause your air conditioner to leak water indoors from a trusted provider of air conditioner and furnace replacement services.

A broken condensate pump

Furnaces and air conditioners installed in the basement have a condensate pump that releases water outside. If this pump breaks, the water won’t get pumped out anymore. This will require you to have the pump repaired or replaced.

A dirty air filter

Dirty air filters contribute to poor airflow. A dirty filter can cause the evaporator coil to get extremely cold and freeze over. Once the ice melts, excess water will drip from the pan. Experts recommend replacing your filters every one to three months, depending on the manufacturer’s instructions.

A clogged condensate drain line

The most common cause of AC water leaks is a clogged condensate drain line. Water will back up into your interior when the drain line becomes clogged with dust, dirt, mold or sludge, so you’ll need to have the drain lines unclogged. However, this job is best left to an AC repair expert. Professionals use a special vacuum to get rid of clogs.

Low refrigerant

Like a dirty air filter, low refrigerant will reduce pressure in your air conditioning system, also causing the evaporator coil to freeze. Again, when the ice on the coil melts, water will leak from the pan. You’ll know your unit doesn’t have enough refrigerant when the AC stops cooling properly or emits a hissing or bubbling sound.

What Are the Pros & Cons of HEPA Air Filters?

Tue, 18 Aug 2020 17:16:16 GMT

What Are the Pros & Cons of HEPA Air Filters?

Today, making the air you breathe as clean as possible is more important than ever. The air filter in your heating and cooling system is essential to maintaining good indoor air quality. However, standard air filters don’t do a great job of cleaning the air because their main function is to protect the mechanical components of your HVAC system from wear and tear.

In this blog post, discover the pros and cons of installing HEPA air filters as well as how they work from an air conditioner repair expert.

Pros

Experts use the minimum efficiency reporting value (MERV) system to rate the efficiency of air filters. This rating ranges from 1 to 16. A filter with a high MERV rating is more likely to contribute to good indoor air quality. HEPA filters are over MERV 16, meaning they remove 99.97 percent of particles up to the size of 0.3 microns.

Hospitals usually use HEPA filters because they remove both inorganic dust and microorganisms such as mold spores, pollen, dust mites, bacteria and viruses. Standard filters use flat fiberglass media, while HEPA filters are made from pleated media to increase their surface area for filtration, which can also increase their lifespan. When it comes to HVAC air quality , these filters are something you should consider.

Cons

The problem with efficient air filters is that they can limit your system’s airflow. Keep in mind that HEPA filtration isn’t ideal for all residential systems. A skilled HVAC technician can determine if your system is suitable for this type of filter.

Moreover, some HEPA filtration options feature whole-house air filters connected to the ductwork through a bypass loop. These units take the air out of the ducts and covey it through the HEPA filter array, then return it into the ducts without affecting airflow.

Handling Dead Animals in Your Air Ducts

Tue, 09 Jun 2020 22:25:09 GMT

Handling Dead Animals in Your Air Ducts

The possibility of dead animals getting trapped in the air ducts isn’t something most homeowners normally think about or prepare for. It is, however, a much more common issue than you might think. This occurrence causes discomfort due to the foul odor the carcass emits. Attics, basements and wall crevices are enticing places for small animals to seek refuge, and air ducts help them maneuver their way through your home. This issue, if not addressed immediately, could wreak havoc on your ventilation system and require you to call a home furnace repair specialist.

As a homeowner, it’s up to you to prepare for this situation. Follow this guide for handling dead animals in your air ducts:

Locate the Carcass

As unpleasant as it may sound, it’s important to follow your nose. If you can’t bear the stench, dab the area beneath your nostrils with menthol ointment to neutralize it. First, shut off your HVAC system and open all your windows for the foul odor to escape. Leaving your HVAC system running will cause the odor to circulate through your home. Turning off your HVAC system allows the smell to dissipate until it’s isolated to the area where the carcass is located. You may have to smell each air register until you isolate the vent with the strongest odor. The carcass will be in this area.

Remove the Carcass

Once you locate it, you can call a trusted professional to remove the carcass or do it on your own. Should you decide to do it yourself, you’ll need a flashlight, screwdriver, gloves, trash bag, tissue paper and disinfectant cleaner. Start by unscrewing the register cover, then use your flashlight to peek inside the air duct to see if the carcass is visible. If you can’t locate it, you may need to use a small camera. Once you find the body, you can use your gloves or a broom to grab it and dispose of it in a garbage bag. If the animal proves too difficult to remove or dispose of, contact your trusted air conditioner repair company to handle the situation.

Clean the Area

After you’ve removed the carcass, sanitize the affected area with a disinfectant cleaner. If the area is hard to reach, you can opt to use a mop with a long handle to clean the affected surfaces to prevent mold and bacteria growth. To ensure that this won’t happen again, have a professional thoroughly inspect your air ducts and the rest of your HVAC system for any holes or other damage.

Overall, this process can be done on your own, but we recommend that you leave it to the professionals so that they can ensure every step is taken properly and do what it takes to prevent this problem from happening again.

5 Signs That Says You’re A/C’s Fan Motor is Failing

Mon, 13 Apr 2020 22:10:49 GMT

5 Signs That Says You’re A/C’s Fan Motor is Failing

As a homeowner, you tend to rely on your air conditioner to keep your home cool and comfortable all year ’round, especially during the summer months. It’s understandable if you want it to remain in good condition as much as possible. Unfortunately, A/C repair pros say that there are some instances when your air conditioner’s fan motor could fail. and it’s your responsibility to look out for the signs that it is.

Here are five signs that say your A/C’s fan motor is failing.

The Fan Runs Even After the A/C Is Shut Off – If you turn off your A/C and notice that your fan is still running, it’s possible that your thermostat is the issue and will have to be replaced. Unfortunately, if a professional looks at the unit and says that the thermostat isn’t the problem, then it’s likely the issue is caused by a stuck relay switch. If the relay switch is stuck, the circuit will remain closed, preventing the electricity powering the fan motor from stopping and allowing the fan to continue running as a result.

The Fan Won’t Start Even When the A/C Is On – Alternatively, the opposite can occur as well; the fan may not start even when the A/C is turned on. This is a clear sign that there’s something wrong with the motor, and if this happens, the evaporator coils of your unit can freeze over. This puts your unit at risk of sustaining even more serious damage. Should you notice that this is occurring with your A/C, turn it off and call an A/C and home furnace repair pro immediately.

Rattling or Buzzing Noises from the Condenser Unit – If you’re hearing noise from the condenser unit when you turn on the fan, there could be many causes. For instance, there may be loose stones or debris caught in it, or loose and unbalanced fans might be striking the unit’s side. However, if neither of these are the cause, it’s most likely the fan motor that’s causing the issue, and this is a sign that the motor is reaching the end of its lifespan and will have to be replaced.

The Fan Is on But Rotating Slowly – On the other hand, if your A/C unit’s fan is rotating slowly even when it isn’t set to low speed, the motor bearings may have to be oiled for it to spin smoothly again. However, it’s also possible that the capacitor is failing and will have to be replaced.

The Fan Runs Intermittently – If you notice that your A/C’s fan is running intermittently, there are two possible causes for this: the first is that the motor could be overheating and causing it to cut out, the second is that a loose wire or a short in the motor windings could be the culprit. Either way, it’s an issue that you shouldn’t handle on your own, so don’t hesitate to contact a professional if needed.

Are you looking for experts who can help you replace your air conditioner? If so, don’t hesitate to turn to Cooper Bros, the leading experts to approach when it comes to A/C and furnace replacement services.

When you use your air conditioning unit, water is a byproduct while it’s running. Normally, that water will be drained out of your home but if your A/C unit’s condensate drain becomes clogged, it can cause the water to leak from your air conditioner. But what exactly causes clogs in AC drains?

In this post, air conditioner repair pros from Cooper Bros explain everything you need to know about A/C drain clogs.

Causes

There’s only one way for your air conditioner’s condensate drain to develop a clog and cause your drip pan to overflow. According to experts, clogging occurs when the moisture that drips off your evaporator coil carries dirt, small debris and other airborne particles into the condensate drain. The dirt and airborne particles will eventually build up and cause a clog.

Signs

There are many signs that indicate your unit’s condensate drain line is clogged. One of these signs is standing water. While a small amount of standing water isn’t much of a concern, if you notice that the volume is more than usual, consider calling an A/C repair expert to inspect the unit.

Another way you can determine whether your condensate drain line is clogged is by examining the condensate pan. Like standing water, if the condensate pan becomes full time and time again, it’s likely that your A/C unit’s drain line is clogged and will have to be repaired immediately to prevent mold growth and water damage.

Prevention

Thankfully, preventing your air conditioner’s drain line from clogging can be done in a few simple steps. First, you’ll need to ensure that the drain line is regularly cleaned by a professional to prevent fungus and excess water from building up and causing issues. The second step you’ll need to take is to replace your old air filters with high-quality ones. By doing so, you can prevent dust particles from building up on the evaporator coils.

Why Your Heat Pump Can’t Reach the Set Temperature

Wed, 05 Feb 2020 17:40:52 GMT

Why Your Heat Pump Can’t Reach the Set Temperature

With proper maintenance, you can keep your heating system in good condition for many years. However, certain problems can still occur, especially during extreme weather. For instance, in the winter, heat pumps sometimes struggle to reach the set temperature, affecting your indoor comfort.

Find out what may be causing this problem from a furnace and air conditioner replacement expert.

Outdoor Unit Failure

If your outdoor unit fails, inspect the power supply and replace the filters. You may feel cold air coming from the vents when the equipment is in defrost mode and you don’t have a supplemental heating system. While this is normal, you should contact a professional if the unit doesn’t turn back on once the defrost cycle ends.

Frosted Outdoor Unit

Running a defrost cycle will usually fix a condenser unit that’s iced or frosted over. However, you’ll need to contact a heating and air conditioner repair expert if the entire unit is covered in ice.

Cold Air Entering the House

To keep the heat contained inside your home, make sure that the windows and doors are tightly closed. Sealing air leaks around your house can help minimize energy loss, saving you on heating and cooling costs. Your attic and basement should also have sufficient insulation.

Closed Vents

User error can sometimes cause problems. Check to make sure all your vents and registers are open. When your supply and return vents aren’t open, the heat won’t be able to disperse throughout the house.

When to Call a Professional

Keep in mind that heating and cooling system repairs are best left to professionals. Attempting to do the job on your own may cause more harm than good. You’ll need to contact an expert if the unit’s compressor isn’t running or if the compressor valve is faulty. Thermostat issues, refrigerant problems and heat pump maintenance are also best handled by the pros.

4 Best Practices to Observe When Using a Programmable Thermostat

Sat, 18 Jan 2020 19:13:07 GMT

4 Best Practices to Observe When Using a Programmable Thermostat

Getting the most out of your programmable thermostat has its benefits. For one, it can help you save at least 10% on heating and cooling costs a year. As a leading air conditioner repair contractor in the area, Cooper Brothers, Inc. recommends you follow these five best practices when using this important component of your HVAC system.

Pick the right thermostat model.

Programmable thermostats in the market vary in terms of customization levels, so you must choose the right one that matches your family’s weekly schedule. A 5-2 model is a thermostat model that allows you to set your indoor temperatures during weekdays and another during weekends. A 7-day model helps you customize different temperature settings for every day of the week.

Adjust your thermostat when your home is empty.

When most members of your family are away from school or work, it’s not good to keep your HVAC system running on a higher thermostat setting. Adjust the setting back from the time your home is empty until everyone is back.

Don’t overdo setting your thermostat back.

It’s good to set back your thermostat settings when you are out for the night or when everyone is not around, but A/C repair pros recommend not to overdo it for the sake of achieving energy savings. Adjusting your thermostat to about five degrees at a time is enough so as not to force your furnace or A/C equipment to work too hard just to bring your indoors back to its normal temperature.

Use the thermostat’s hold setting .

If you and your family are out of your home for an extended time, be sure to take advantage of the thermostat’s hold or vacation setting. For this, you can set temperatures back to about 55 degrees for maximum savings.

How to Protect Your Central HVAC System During Remodeling

Thu, 12 Dec 2019 18:25:20 GMT

How to Protect Your Central HVAC System During Remodeling

Any remodeling project can be hard on your central HVAC system. You can expect large amounts of airborne dust during construction, so you’ll want to make every effort to minimize the negative impact of home renovations on your heating and cooling equipment.

Before you begin with your home improvement project, follow this advice from Cooper Brothers:

Consult Your HVAC Professional

After laying the groundwork for your remodeling project, discuss your plan with your trusted A/C repair or furnace installation technician. An HVAC professional who knows your system can determine whether some aspects of the job might be detrimental to your heating and cooling units.

Keep the Mess Outside

Dust may be inevitable, but it can be reduced. One way to minimize the number of contaminants in the air inside your house is by doing prep activities such as standing and cutting outside.

Close Registers and Vents

Restrict the entry of dust into your HVAC system by closing off your registers and vents for the time being. You shouldn’t be using your heating or cooling equipment during construction anyway, but if you must run your furnace or A/C, make sure enough registers and vents are open to prevent choking your units.

Putting a Premium on Dust Control

Any furnace and air conditioner repair specialist will advise you to ask your remodeler about dust control. There must be a protocol in place to protect sensitive HVAC equipment from construction, dirt and debris. Also, make sure your home improvement contractor is contractually obliged to clean the work areas regularly.

Maintain the Filter More Often

The frequency of air filter maintenance doubles during remodeling projects. Don’t let appearances fool you; a rather clean-looking filter can still be clogged enough to inhibit proper airflow.

Schedule Duct Cleaning Afterward

To reduce the chances of dealing with an emergency A/C or home furnace repair , have your entire duct system cleaned post-renovation. It is best to schedule your duct-cleaning appointment in advance and get it done right after construction ends to minimize indoor air pollution.

Let Cooper Brothers help keep your central HVAC system in good shape both before and after your home improvement.

Understanding Thermodynamics: Avoiding HVAC Issues

Wed, 13 Nov 2019 21:53:21 GMT

Understanding Thermodynamics: Avoiding HVAC Issues

Heating and cooling are critical components of a comfortable home life. Without an HVAC system, your winters would be unbearably cold and your summers swelteringly hot. Your HVAC unit works quietly in the background, keeping your home warm and toasty or cool and comfortable, but even the best systems can encounter problems in the long term. Sometimes, HVAC units break down prematurely, which means you could need an air conditioner replacement in the middle of searing summer heat. In most of these cases, it’s not a problem with the HVAC system itself, but rather a matter of upkeep–or more accurately, the lack thereof.

To help you maintain your HVAC equipment and enjoy its benefits for as long as possible, it’s important to have a basic understanding of thermodynamics, the branch of physical science that has to do with how heat interacts with other forms of energy. Your HVAC system–and truly, your entire home–is a prime example of that interaction.

Here are the principles you should be aware of that will enable you to take better care of your heating and cooling equipment.

Heat Goes Where the Cold Is

Heat likes balance, which means it seeks to occupy as much space as possible. When you open the door of an air-conditioned room, for example, the cold air doesn’t rush out; rather, the hot air outside rushes in, and will keep doing so until the temperature in the room is equal to the temperature outside. This is why it’s important to keep your windows and doors closed when your air conditioner is running. Seal any gaps where cold air can escape and hot air can enter, such as the space around lights and poorly sealed windows. Keeping your air conditioned rooms properly sealed will prevent your cooling equipment from becoming overworked, which can shorten its lifespan, increase energy output and lead to frequent air conditioner repair or even premature replacement.

Convection

When hot air is trapped, it tries to escape by rising. The spaces around lights and other such areas serve as passageways for heat to escape. In the winter, this rising heat may make your upstairs rooms warmer than the downstairs living areas. It can also make the attic too hot, baking your shingles and possibly causing moisture buildup (condensation), which can damage almost anything it touches.

The best step to take is to call a professional to perform a thorough inspection of your home. Keeping your home tightly sealed against escaping or entering air will keep it from encountering problems related to thermodynamics.

How an Excess of Dust Can Damage Your HVAC System

Wed, 13 Nov 2019 19:52:36 GMT

How an Excess of Dust Can Damage Your HVAC System

Your heater and air conditioner draw in outdoor air that can contain dirt, dust, pollen, mold and other harmful particles. When regularly replaced, the air filters are usually able to catch these contaminants. If you don’t change filters at least once every three months, though, the inside of your HVAC system will become dirty.

Learn the consequences of excessive dust in your HVAC system from your home furnace repair expert.

Breakdowns

Excessive dust inside your HVAC system can cause damage and breakdowns. The coils can’t work efficiently if they’re covered in dust. So, your home may remain hot or cold even when your air conditioner or heater is running. Poor airflow will create drafty or warm areas in your home, and the resulting wear and tear from this and the aforementioned issues can lead to early system failure. If you don’t take care of dust in your system right away, you may end up having to replace your furnace or air conditioner because of it.

Decreased Energy Efficiency

Too much dust in the air filters, ductwork and your indoor unit will make your system work harder, wasting energy and increasing utility costs. Hire a professional to check and clean your system if your power bills remain high despite your best efforts to save energy. They can also determine if you need a furnace or A/C repair .

Ice on Your AC

In air conditioners and heat pumps with excessive dust, the coils won’t absorb or release sufficient heat to keep your indoor spaces comfortable. Over time, ice will form on them, damaging the compressor and other components of your HVAC system. Turn off your system if you notice ice on your indoor or outdoor unit. Don’t attempt to remove the ice yourself, as you may end up causing more harm to the system.

Prevent problems such as these by hiring an experienced contractor like Cooper Bros Inc. to maintain your HVAC system. With our preventive care plan, you can improve the performance of your system while extending its life at the same time. We also offer high quality air conditioner and furnace replacement services.

How Carrier® Became a Trusted Name in the Industry

Fri, 20 Sep 2019 18:11:12 GMT

This is a subtitle for your new post

Choosing an HVAC brand can be tricky. While homeowners often consider a company’s customer service and product reviews before making a purchase, there’s another important factor that shouldn’t be forgotten—the company’s history. With a rich history comes expertise.

The history of Carrier® stretches back to the start of the 20th century. The air conditioner repair experts at Cooper Brothers Inc. give a quick recap of how Willis Carrier founded the company and invented modern air conditioning below.

How It All Started

Finding comfort back then was hard, with hot, steamy weather often keeping people awake at night. But that all started to change with one observation: Carrier realized he could control moisture levels in the air by passing it through water to create fog. Humidity control is an essential function of any air conditioning system.

Carrier got the idea while working for Buffalo Forge Company in 1902. In the same year, he invented the world’s first scientific air conditioning system. Thirteen years later, Carrier left the company to establish the Carrier Engineering Corporation.

The Spread of Air Conditioning Systems

The first air conditioning system was installed at a printing plant in 1902. The first commercial installation was in a movie theatre in Detroit in 1924. Five years later, air conditioning systems gained national recognition. In 1929, the Carrier Corporation installed air conditioning systems in the U.S. Senate and House of Representatives. Eventually, air conditioning systems would spread to households as well.

The Carrier Corporation Today

Throughout its history, Carrier has made a series of acquisitions and was itself acquired by United Technologies Corporation. For almost a century, the company has navigated economic headwinds and market disruptions to cement its position as a leading manufacturer. To maintain this position, Carrier has produced over 50 brands and continues to make innovations, particularly in energy-efficient features, through joint ventures with other companies.

Carrier products are known for their quality and cutting-edge features, which you won’t be able to enjoy if they’re not properly installed. That’s why, whether it’s an A/C repair or installation work, you should only hire experienced contractors.

Tips to Help You Calculate the Right Size for Your A/C System

Mon, 19 Aug 2019 17:54:12 GMT

Tips to Help You Calculate the Right Size for Your A/C System

An undersized or oversized air conditioning system can cause a lot of problems. For instance, an air conditioner that’s too small will consume too much energy while still failing to cool the home properly. An oversized air conditioning system, on the other hand, will constantly short cycle. Electric bills also tend to be high in both cases. In today’s article, Cooper Brothers, Inc., the leading expert in air conditioner and home furnace repair in our area, provides some tips to help you choose the right size of air conditioner.

Sizing Your Air Conditioner

The cooling capacity of your air conditioning system is measured in BTUs, or British Thermal Units. To figure out what size air conditioner is right for your home, you’ll first need to calculate the size of the spaces that will be served by the air conditioner. Multiply the length times the width of the room or area to be cooled to calculate the size of the area in square feet.

Next, you’ll need to multiply that total by 25 BTU. For example, if a room is 15 feet long and 12 feet wide, then it has an area of 180 square feet. Multiply 180 by 25, and you’ll get 4500. This means that you need to get an air conditioner that has a minimum of 4500 BTU in cooling capacity. Don’t buy an air conditioner that has a cooling capacity that’s too large for the size of the room. As an A/C repair and replacement expert, we recommend choosing a system that’s neither too small nor too large.

Why You Should Work with a Professional

Figuring out the area of your interior and multiplying it by 25 BTU is a good way to get a ballpark figure. However, for best results, we still recommend consulting with a professional HVAC company and asking them to inspect your home. We have the training and tools to accurately figure out the best air conditioner size for your home. Our calculations will take a lot of other factors into account because we aim to install the most energy-efficient air conditioning system for your home.

The History and Applications of the HEPA Filter

Thu, 06 Jun 2019 22:33:24 GMT

The History and Applications of the HEPA Filter

Indoor air quality is important to homeowners, especially when there are household members who are prone to allergies. Most homes just have the standard equipment installed, which unfortunately is inadequate for keeping your air as pure as it should be.

This is where HEPA filters come in. HEPA filters are an HVAC component often recommended by A/C repair experts, and are considered the gold standard when it comes to keeping your indoor air pure. With that in mind, it’s best to learn as much as you can about this type of filter. In this post, Cooper Brothers, Inc. discusses the history of the HEPA filter and where they’re usually used.

HEPA Filters: History

HEPA filters were first designed in the 1940s but weren’t used in homes at that time. Instead, they were created to protect nuclear facility workers from breathing in irradiated airborne particles. By the 1960s, they moved to hospitals, where they were used to help prevent the spread of airborne germs. Finally, HEPA filters made their way to American homes, particularly in household appliances. In fact, they’re so efficient and effective that the Environmental Protection Agency says they can remove more than 99% of airborne pollutants.

According to furnace replacement experts, having HEPA filters in your home is a good thing because they allow those who suffer from allergies or asthma to finally receive get some form of relief. This is because the HEPA filter easily traps the airborne particulates that can trigger respiratory symptoms, allowing them to live in relative comfort indoors.

Applications for the HEPA Filter

HEPA filters can be found in three common home appliances: the HVAC system itself, portable air purifiers and vacuum cleaners. Having one or all these appliances can aid in keeping your indoor air clean and pure and help alleviate any allergy symptoms. Portable air purifiers can reduce airborne contaminants such as dust and dander by drawing air into the unit and blowing it back out via the HEPA filter.

A whole-house HEPA purifier, meanwhile, can remove allergens from the air through your HVAC system, and is more effective than a portable air purifier. Finally, there are also HEPA vacuum cleaners. These allow you to collect and trap any harmful particles that may be on the floor before they have the chance to become airborne.

How to Adjust Your HVAC for Daylight Savings Time

Wed, 06 Feb 2019 18:52:31 GMT

How to Adjust Your HVAC for Daylight Savings Time

Every year, people across America (except those in Arizona and Hawaii) move their clocks one hour forward in the spring and one hour back in the fall. While this practice that aims to make use of longer daylight hours in the evening has been in effect as a federal law since 1966, many people still have a hard time remembering which way the clock moves when Daylight Saving Time (DST) rolls around each year. This year, DST starts on March 10, which is the second Sunday of March, and ends on November 3.

In this article, air conditioner replacement company Cooper Brothers, Inc., discusses essential things to remember when adjusting your HVAC system to coincide with local DST.

Why Adjust Your HVAC?

Along with the challenges to your body clock, DST also affects your home’s heating and cooling schedule. Adjusting your smart thermostat’s schedule accordingly allows you to reap the benefits of an extra hour of heat and light. In other words, adjusting your HVAC unit’s schedule ensures efficiency. Waking up an hour earlier and getting used to leaving the house when it’s still relatively dark can be a difficult adjustment, and having your HVAC system ready when DST arrives gives you one less thing to worry about.

Allow for an Acclimation Period

According to air conditioner repair and HVAC experts, you should synchronize all the thermostats and clocks in your home. To get the most out of your programmable thermostat, set the temperature to raise or lower one hour before you must leave the house, then return to your preferred settings an hour before you arrive home. In this way, you’re saving energy while you’re away, and allowing your home to reach an ideal level of comfort by the time you get back.

Benefits

Adhering to DST may seem like a nuisance at times, especially because of all the adjusting you must do. However, you stand to save as much as 10% on your annual utility bills if you cut back on temperature levels for at least eight hours a day. Syncing your HVAC system with DST can also help reduce maintenance and repair costs by decreasing demand on the system.

The Importance of the ENERGY STAR® Label

Fri, 25 Jan 2019 19:32:01 GMT

The Importance of the ENERGY STAR® Label

Whether you’re replacing an old heater or buying a new air conditioning unit, it’s important to always check for the blue ENERGY STAR® label. While it shows the technical specifications of the unit, it also serves as a buyer’s guide for those looking for the most energy-efficient unit possible.

Cooper Brothers Inc., your heating and A/C repair experts, discusses in-depth the importance of the ENERGY STAR label.

What’s In the Blue Label?

The ENERGY STAR label outlines the energy efficiency specifications of the heater or air conditioning unit. The rating compares the energy performance of the product to the minimum efficiency requirements set by the federal government. As a rule, a heater or A/C unit needs to be 10% more energy-efficient than the standard model to get the blue label.

There are a few details worth noting on the label, two of which are the estimated yearly operating cost and the estimated yearly electrical use of the unit. The former is an estimate of how much the unit costs to run while the latter details how much power it will consume on average within a year. Both are important considerations on your next air conditioning or furnace replacement.

The Benefits of Installing ENERGY STAR Equipment

The most important benefit of installing an ENERGY STAR-rated heater or air conditioner is reduced energy consumption, which translates to savings. These systems are designed to meet and adapt to the climate of a local area, which means it’s always efficient at generating and supplying your home with warm and cool air.

Since these units are as energy efficient as possible, they also don’t encounter problems that plague non-rated units. ENERGY STAR heaters and A/C units also last longer and only require general maintenance and cleaning to ensure smooth operation.

At Cooper Brothers Inc., we install your new heating and cooling systems with the utmost care so you can take full advantage of their energy-efficient benefits. We offer home furnace repair , timely replacement , and preventive care services.
