Why Odd Noises Are Coming from Your Air Conditioner

If you’ve had your air conditioner for any length of time, you’re probably familiar with what it normally sounds like when it runs. Sometimes, however, you’ll turn on your air conditioner and be greeted with a completely different set of noises. This typically indicates a problem with your air conditioner, though the kind of problem ranges in severity from minor to serious threat. If you’re not familiar with what each sound means, though, it can be difficult to tell whether it’s an emergency or not. Let’s take a look at some of the common noises, and what they mean.

Grinding

If you hear a grinding noise, it’s almost certainly coming from your air handler. The air handler is the part that circulates the conditioned air throughout the house. The air handler motor has a number of lubricated bearings inside it, which help to reduce friction while it is running. If the bearings start to wear down, the friction on the motor will increase and generate that grinding sound. If not fixed soon, the air handler motor will eventually burn out and need to be replaced.

Hissing and Gurgling

This one is harder to detect unless you are close to your actual air conditioning unit. If you hear a hissing or gurgling noise coming from your air conditioner, it is very likely that you have a leak somewhere in your refrigerant line. The refrigerant in your air conditioner is not supposed to be consumed, which means that if the refrigerant levels start to drop your system will begin to malfunction. If the leak isn’t found and sealed quickly, the refrigerant levels will drop to the point where the system will break down.
