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.
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 AC repair and replacement expert, we recommend choosing a system that’s neither too small nor too large.
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.
