Air handler is a device used as part of any heating, ventilating, and air-conditioning (HVAC) system and its job is to effectively circulate conditioned air throughout a building. A air handler typically includes a blower, heating or cooling elements, filter racks or chambers, sound reducers, and vibration dampers, concealed in a metal box.



An air handler helps in making an HVAC system more effective. This can be realized when the basic functioning of an air handler is understood. Any central air conditioning system consists of two key divisions…first is the outdoor unit and second is the indoor unit. An air handler is typically connected to the duct that distributes conditioned air and circulates conditioned air throughout your home. Some air handlers come with inside coils and blower fans which acts as an auxiliary electric strip heater.

Nowadays air handlers are available with single speed motors for recurrent use, variable-speed motors for all year round effectiveness, and for additionally functionalities for humidity control features and selectable levels of airflow capacity. You can also choose air handlers for enhanced comfort mode.

Air handlers can make also contribute to overall efficiency of an HVAC system. This is because more efficient the air handler less work for the outdoor cooling unit, which, in turn means lesser electricity consumption. The onus is on matching the size of an air handler effectively with the HVAC system to produce the right amount of clean and conditioned air.
