What Various Air Conditioning Noises Mean

If you’ve had your air conditioner for a summer or two, you probably know what noises it’s supposed to make while it’s operating. What does it mean when your air conditioner starts making some very unusual noises, though? That entirely depends on the noises you’re hearing. It’s best to call for a professional any time you hear an unusual noise coming from your air conditioner. While you’re waiting for them to arrive, though, here are a few possible causes of weird air conditioner noises.

Short Cycling

Short cycling is when your air conditioner starts turning itself on and off every few minutes, much more rapidly than it normally does. This is caused by a number of different things, but the important thing to remember is that it’s a major threat to your system. If the short cycling isn’t dealt with immediately, it can shorten the life of the system and increase the chances of a breakdown.


A grinding noise is likely located in the air handler section, which is responsible for circulating air throughout the house. The air handler motor is outfitted with a number of lubricated bearings, which help to keep friction low while the system is running. As the bearings start to run down, they actually become a drag on the motor. If not replaced, the motor will eventually overheat and burn itself out. Replacing an air handler motor is very expensive, and not something you should ever have to do. So do yourself a favor and call for repairs as soon as you notice that grinding sound coming from your air conditioning system.
