Why Is My Air Conditioning Making A Grinding Noise?

You need an air conditioner you can depend on if you live in Florida.

If your AC starts sending you signals that it might be struggling or heading toward a breakdown, you need to act fast to get it the necessary repairs.

Is that grinding noise from my AC a warning sign?

Strange noises are one of the ways you can tell if your air conditioner is encountering trouble. You are probably familiar with the sounds your AC makes during normal operation, so when something like a grinding noise starts, it will stand out—as it should. A few of the main causes of this pesky grinding noise we see on a routine basis include:

  1. Trouble with the compressor: This is the #1 most likely cause of this issue. This vital component is what sends the refrigerant through the air conditioner’s lines and allows for heat exchange. Compressors operate similar to motors, with pistons that compress the refrigerant inside. If the compressor wears down, the pistons can start to cause an unpleasant grinding noise. Other internal components may have broken or come loose. Usually, the compressor will need a full replacement, which is a job trained HVAC professionals can get done for you.
  2. The blower fan belt has come loose: Occasionally, this component comes loose and starts to rub against other parts of the air conditioner’s cabinet. The damaged belt will need to be changed before it causes further trouble for other components. This isn’t like changing the motor belt in a car: it requires special knowledge and the right tools.
  3. Lack of Motor Lubrication: Sometimes with older units (and newer ones if they are put through the ringer like they do here in Jacksonville) the motor needs additional lubrication to continue to run smoothly and quietly. While this is a small fix if you catch it early, over time it can cause real damage to your AC’s motor.

Please keep in mind that your air conditioner may still seem to function normally even with these problems occurring. Don’t give into the temptation to just tolerate the sound and try your best to ignore it—the problem will not go away, and it will get worse until a major malfunction occurs that will require expensive repairs. When you hear these grinding noises, call in HVAC professionals who will be able to identify where the issue lies and fix it so it won’t reoccur.
