How Air Handlers Work in Your Heating System

If you used a forced-air system to heat your home, such as a furnace or a heat pump, one of the essential components of the unit is the air handler. The air handler performs the crucial task of air distribution through the ventilation system and into the rooms of your house. Without the air handler, the heat from the burners or heating elements in the furnace, or the coils in the heat pump, would go nowhere and you would receive no comfort from your system.

Care and maintenance of an air handler is a major part of the job of heating repair technicians. Contemporary air handlers are too complex and intricate devices for amateur work. When you need repairs for the air handler to restore your heating in Coeur d’Alene, WA, you must call up experienced heating contractors. ACI Northwest has the training and years of experience to help you with any trouble you may have in your air handlers or any other part of your heater.

The operation of the air handler

The main component of an air handler unit is a large blower fan inside a durable casing connected to a blower fan motor. Some air handlers have variable speed motors that can run at lower power to reduce noise and to assist with even air distribution. The blower sends out air into the ventilation system; sometimes this is air from the outside or sometimes from the return vents that re-circulate air. Blower fans can sometimes require repairs if the blades become bent from debris that enters the air handler. A filter rack or filter chambers in the blower help keep dust and debris picked up from the re-circulated or outside air from entering into the ductwork. Sound attenuators help reduce the noise from the blower.

For heat pumps, air handlers also contain the coils necessary for conditioning the air in heating and cooling mode, making it not only essential for air distribution, but also for providing a comfortable temperature. (With a furnace, the air handler usually plays no role in generating heat.) For ductless mini split heat pumps, the air handlers are often referred to as terminal units, and contain fewer components: usually an air filter, coil, and blower.

Keep your air handler working

Because an air handler is a major mechanical part of your heating system, it needs regular maintenance and prompt repairs to make sure it does not wear down and threaten you with a loss of heat. Should you hear loud banging sounds from the air handler, or if the airflow from your vents drops, you should call for professional repairs as soon as you can.
