Call for Service When You Hear These Sounds

April 20, 2019

You’re accustomed to the comfortable hum of climate-controlled air blowing through your vents. You’re used to the familiar sound of your heating or cooling system switching on and off. All of a sudden, however, you might start to notice new noises coming from your furnace or air conditioner. If that happens, you could have a problem on your hands. The following sounds indicate that it’s time to call in the heating and cooling experts.

1. Shrill Squealing

When high-pitched sounds come through your system, it’s likely that the fan belt has slipped out of place. Having the belt tightened right away can prevent it from wearing out prematurely. You may also have parts that need to be lubricated. Sometimes, adding a bit of oil in the right places can stop the squeaking. However, if your air conditioner starts to sound as if it’s screaming, shut it off right away. You could have a refrigerant leak.

2. Noisy Rattling

Older furnaces and air conditioners sometimes start to rattle or clank as worn-out parts become loose. It may be time to consider heating and cooling replacement. On the other hand, the fix could be as simple as removing trapped leaves or changing your filter.

3. Continual Buzzing

You’ll probably need a professional to diagnose the problem if you hear buzzing noises. These can be caused by a number of different issues:

  • Trapped debris
  • Dirty filter
  • Worn-out fan motor
  • Failing blower

4. Loud Popping

Noisy bangs can be a sign that your system’s sheet metal is bending. You may need to have your ductwork resized to make it a more appropriate fit for your system’s capacity. Opening vents or changing the filter can help as well.

5. Persistent Clicking

If you hear start-up clicks throughout your unit’s cycle, there may be an electrical issue. This is often due to a part that’s no longer working properly, such as a:

  • Relay
  • Thermostat
  • Control
  • Compressor
