Air Handlers

An air handler is used to regulate and circulate air as part of a heating, ventilating, and air-conditioning HVAC system. The unit is usually a large metal box containing a blower and heating and cooling elements. Air handlers usually connect to ductwork that distributes the conditioned air through the building and returns it to the air handler.

Air handler components:

  • Filters—provide clean dust-free air to your home.
  • Heating/Cooling Elements—heat exchanger coils, which vary depending on the type of air handler.
  • Humidifier—helpful in reducing static electricity.
  • Mixing Chamber—uses dampers to control the ratio between the return, outside, and exhaust air.
  • Blower/Fan—pushes conditioned air into your ductwork.
  • Controls—regulate every operating aspect of the unit.
  • Vibration Isolators—reduces noise of operation.

Signs Your Air Handler Needs Repair

  • Fan Unit Problems. If your air handler starts making odd noises or fails to blow any air, the main fan may need to be replaced.
  • Condensate Leaks. If you notice moisture or water pooling below your air handler, a condensate leak is usually the cause. These leaks could cause water damage to your home, so have them resolved as soon as possible.
  • Dirty Filters. Dirty filters can reduce your air handler’s working efficiency by as much as 50%, so it’s important to change them monthly. If you just can’t seem to keep your filters clean, have your unit checked for proper functioning.
  • Contaminated Blower Compartment. A contaminated blower compartment can lead to poor indoor air quality and can create mold problems as well. The best way to avoid this issue is with seasonal maintenance.
