Question: What Is An Air Handler?

An air handler is usually a large metal box containing a blower, heating or cooling elements, filter racks or chambers, sound attenuators, and dampers.

Air handlers usually connect to a ductwork ventilation system that distributes the conditioned air through the building and returns it to the AHU. In some instances, with a ductless mini or multi-split the air handler may NOT require a duct system at all, therefore the name is ductless.
