Sound That Signal Your AC Unit is Failing

The summer is here and the mercury is continuing to rise throughout the country at a dangerous rate. That is why having your air conditioning unit up and running has gone from a comfortability benefit to a necessary health need. But with the rising heat index, the unit may be pushed to and possibly beyond its limit. That is why it's so important to keep an ear on the unit as the sounds it makes can be the biggest sign for any homeowner.

Here are the sounds to listen for to signal if your AC unit is failing:

  • Squealing
    • A loud, screaming-like sound normally indicates a belt issue or motor bearing problem. If it happens to be the belt, that is an issue that will liekly need to be repaired by a professional as it is both expensive and difficult to repair. As for motor issues, lack of lubricant can be the main problem.
  • Banging
    • If it sounds like something is rattling and banging inside the unit, it's likely an issue with the blower or motor. The noise is coming from a loose object inside and is an issue that has to be fixed immediately before it causes permanent damage.
  • Clicking
    • The repetitive clicking noise is one of the least worrisome but still an issue to fix. It normally means there is a problem with the relay from the control panel or outside compressor.
  • Rattling
    • If you hear a rattling coming from inside the unit, it's very likely a sign of a piece of the fan or motor coming loose. This is a sound that should have the unit shut off immediately and repaired before the issue turns into a larger and more expensive problem.
  • Twhapping
    • The sound of a baseball card in the spokes of a bike tire is normally the sound of a piece of debris or loose item contacting the fan. Make sure to fix this issue quickly as well to stop the fan from wearing down and breaking.

The summer heat can cause many issues to both the home and residents. If there are any noises outside of the purring of a well-run unit, make sure to contact us as soon as possible so our professionals can get to your home and fix the unit before any permanent damage is done.
