Air conditioners are supposed to keep your home cool in the year’s hottest months. But, it can be annoying when you hear strange noises coming from yours, especially a squeaking sound. Fortunately, there are three possible reasons for the noise, and by knowing what they are, you’ll be able to find a solution that works for you.

1. The Fan Belt Is Worn Out or Misaligned

If your air conditioner starts to make a squeaking sound after you turn it on, you may have a problem with the fan belt or pulley. The fan belt is responsible for driving the compressor, which cools the air before sending it into your home. A worn-out or misaligned belt could cause a squeaking sound.

If this belt is worn out or misaligned, it will transfer power unevenly, which causes it to make a grating noise. Replacing the belt will quiet down your unit, which may be the best option if this is the case.

2. A Failing Compressor

Your air conditioner’s compressor is what pumps the refrigerant throughout the system to keep your home cool. If it fails or is beginning to fail, it will make a squeaking noise as it works harder to stay operational. A failing bearing could also cause noise if the pump moves back and forth unevenly.

If you hear a squeaking sound coming from your air conditioner, your compressor is likely failing, and you should schedule an appointment with a professional. We at CSL Climate Control Company will help you address this issue by inspecting your unit and fixing the issue.

3. The Refrigerant Is Leaking

If your air conditioner is leaking refrigerant, it will work harder to cool your home, which becomes a squeaking noise as the unit’s components wear out. You may notice other signs of a refrigerant leak, like a hissing noise or increased energy bills.

Overall, there are a few reasons your air conditioner may be squeaking, but you’ll want to address the problem as soon as possible. If the bearings or fan belts are worn out, you can replace them and solve the problem. We offer cooling, heating, and indoor air quality services.
