Why Is My Air Conditioner Making Weird Noises?

If you have had your air conditioner for any length of time, you probably know what kinds of noises it tends to make while it’s operating. As you use your air conditioner more and more to keep cool this summer, you should listen for any unusual noises that may be coming from the system. Odd air conditioner noises tend to indicate a problem that needs to be repaired. Let’s take a look at some common air conditioner noises that should prompt professional service.

Grinding

An air conditioner uses a part called the air handler to move air throughout the house during operation. This part is basically a large motor with a fan attached to it. A lot of strain is placed on the air handler motor during operation, so to compensate it’s equipped with a series of lubricated bearings. These bearings help the system to operate more smoothly, but they do wear down over time. When that happens, the friction on the air handler will increase and produce a loud grinding sound. If you hear this sound coming from your air conditioner, call for repairs right away. Otherwise, the air handler could eventually overheat and burn out.

Hissing

If you hear hissing or bubbling coming from your air conditioner, it probably means that there are air bubbles in the refrigerant line. This means that there is a leak in the refrigerant line. A refrigerant leak will cause the system output to steadily decline. Eventually, the system will break down entirely. Call for repairs as soon as you notice this noise coming from your air conditioner. The leak will need to be sealed and the lost refrigerant replaced to restore the system to full function.
