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 ductwork that distributes the conditioned air through the building and returns it to the AHU. Sometimes AHUs discharge ( supply ) and admit ( return ) air directly to and from the space served without ductwork.
