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.
