An air handler is the indoor part of your HVAC system that circulates conditioned air through your home.
If you have a forced air furnace, the air handler is the part that blows the hot air out and circulates cooled air from your air conditioner.
A stand-alone air handler to blows cool air from your air conditioner and/or hot air from your heat pump through your home’s ductwork.
An air handler includes a blower, heating elements and cooling evaporator . Air handlers usually connect to ductwork that distributes the conditioned air through the building and returns it to the air handler.
Air handler care. Changing your filters regularly is the key maintenance for your air handler, whether it’s part of your furnace or a stand-alone unit. You should also have your entire HVAC system inspected and maintained by a professional each year to catch any small problems before they become big.
