What is an air handler?

Your central heating and cooling system consists of two main parts: an outdoor unit (like a heat pump or air conditioner) and an indoor unit (like an air handler or furnace). When matched with a heat pump, an air handler circulates both cool and hot air throughout the seasons. Plus, air handlers make a significant contribution to the overall efficiency of your entire heating and cooling system. The more efficient your air handler is, the less work your outdoor unit has to do to keep your home comfortable.

Air Handlers

Pair air handlers with your air conditioner or heat pump to circulate warm and cool air all throughout your home. Air handlers fit in attics, basements and crawlspaces, and are insulated to prevent sweating and energy loss.
