AC Squealing? Here Are the Possible Causes

Noisy AC in Cheyenne, WY

Your air conditioner shouldn’t make loud noises if it is working correctly. If you suddenly hear your AC start to make squealing or squeaking noises, it is a sure sign that you need to have your system serviced. There are two main issues that can cause an air conditioner to make squealing noises, and both of them will eventually prevent your system from running if not fixed.

Misaligned or Damaged Belt

If you have an older air conditioner, the squealing is usually a sign that the belt that drives the fan motor in the outdoor AC compressor is worn out. You will also hear the same squealing noise inside the house if the belt that drives the blower fan motor is worn.

Heat and moisture can cause the belt to become stretched. The belt can also start to fray or otherwise become damaged. When the belt isn’t in good condition or not properly aligned, it will start to make a squealing noise similar to a squeaky belt in a car. The good news is that the belt can easily be replaced, which will stop it from making noise.

Worn-Out Ball Bearings

Newer AC units no longer use belt-driven motors. Instead, they have direct-drive motors that use ball bearings to spin the fan blade. When these ball bearings begin to wear out, they will start to make a loud squealing noise similar to a worn-out belt. The only solution to fix this problem is to replace the fan motor. If not, the system will eventually stop working.
