An air handler in your heating & cooling system

What is an Air Handler?

An air handler, or air handling unit (AHU), is a device used to regulate & circulate air as part of your heating & cooling system. It's usually a large metal box that contains:

  • Blower / fan
  • Heating and cooling elements
  • Air filters
  • Sound attenuators to reduce noise
  • Controls to regulate all aspects of the air handler
  • Dampers for moving air through the ductwork

Air handlers usually connect to ductwork, but also operate without ductwork.

Small air handlers are called terminal units, and may only include an air filter, coil, and blower. These small units are called blower coils or fan coil units. A handler that conditions only outside air, not recirculated air, is known as a makeup air unit (MAU) or fresh air handling unit (FAHU). An air handler designed for outdoor use, usually on roofs, is called a packaged unit (PU), heating and air conditioning unit (HCU), or rooftop unit (RU).
