Common Air Handler Problems

Posted on: August 12, 2014

Your air handler is an important part of your HVAC system. If your air handler system is not working, it can cause a lot of trouble when it comes to cooling your home. 

Air Handler Issues and What to Do About Them

Noisy Air Handler

If there are unusual noises coming from your air handler, then you will want to do a quick diagnosis to find out what the problem may be. Here are some of the more common noises you may hear:

  • Louder than Usual and Vibrations – If your air handler starts sounding louder than usual and a vibrating accompanies the noise, your air handler may be off balance.
  • Roaring or Hissing – This is likely due to duct connections that are leaking air. By reconnecting the leaky ducts you may be able to stop the roaring and hissing noises from occurring.
  • Humming – If there seems to be a loud humming sound coming from the air handler, this could be due to a few things. A dirty blower wheel may cause the humming and cleaning the wheel could help. It may also be due to a bad motor; in this case you will need a professional to assess your air handler.

Air Handler Not Working

If your air handler stops working and there is no air movement, the most common reason is a broken belt. First, make sure the belt is in place. If it is and your system is still not working, call a professional so that more damage is not caused to your system.

Air Handler Leaking

If your air handler is leaking water on to the floor, it could be due to condensation accumulating in your system. If your condensation pan is not working correctly, it can cause this build up to leak from your system.

The condensation pipe may also be the culprit. If this pipe is clogged or has a crack in it then leaks are bound to happen. If it is clogged, you can clean it with a small piece of wire. However, if you inspect the pipe and you find a crack in the pipe or your pan is bent or damaged, call a professional.
