Why Is My Air Conditioner So Loud?

Posted on

It’s the height of summer, and the last thing you want is for something to go wrong with your cooling system. If the sound of loud, unusual air conditioning noises can be heard throughout your home, it’s easy to become alarmed. For most people, it’s difficult to tell which noises are harmless and which ones could signal it’s time for AC repairs. We’re here to walk you through the most common air conditioning noises so you can evaluate the severity of your issue and call a professional if you need to.

Common Air Conditioning Noises—And What They Mean for You

Not all air conditioning noises indicate a major problem. Below are just a few of the most common reasons your system is making such a racket:

  • A dirty fan or filter. If your filter is clogged with dirt and debris, it can cause loud air conditioning noises. Fortunately, this issue can be easily remedied and prevented with a thorough cleaning or a filter replacement. Routine service visits each spring can help you avoid the issue altogether. A system that needs to be cleaned is not only noisy, but also works harder, using more energy and costing you more on your utility bills—so don’t wait to deal with the issue!
  • A system that need lubrication. Another common cause of air conditioning noises is the need for system lubrication. This can also be handled during your annual service call.
  • Leaky ductwork. Ducts that are coming apart can make a rattling sound that you’ll hear all over the house. Leaky ductwork can also be costing you more than necessary in your electric bill. A professional can get your ducts sealed to eliminate this issue.
  • A problem with the fan. A loose can blade can cause a grinding sound to come from your unit. The fan can also get noisy if the screws become loose. If tightening the screws doesn’t solve the issue, it’s time to call your AC repair company.
