Air Handler
An air handler is a critical component of an HVAC system that circulates and regulates air as part of the heating, ventilating, and air conditioning system. Typically housed in a large metal box, it encompasses a blower, heating and/or cooling elements, filter racks or chambers, and dampers. Air handlers connect to ductwork that distributes the conditioned air throughout a building and returns it to the air handler. They are crucial in efficiently maintaining indoor air quality and comfort by ensuring that air moves through the system as intended, often working in tandem with outdoor units in split systems.
