What It Means When Your Air Conditioner is Making Strange Noises

When it comes to preserving the health of your air conditioner, a quick response to problems is paramount. That can be rather difficult, though, if you can’t identify when your system is actually in trouble. One of the best ways to do that is to listen for strange noises, which are typically among the first identifiable external symptoms of a problem. Let’s take a look at some of those noises now, and what they mean.


Your air conditioner moves air around your house by using a part called the air handler. The air handler is little more than a large motor attached to a fan, which is constantly blowing air through the ducts. It takes a lot of force to move that much air, so to compensate for the strain the motor is outfitted with oiled bearings. These bearings wear down over time, however, causing the friction on the motor to increase. This makes a loud grinding sound. If you hear that sound, you need to call for repairs right away. If the bearings fail completely, the air handler motor can overheat and burn out.


If there is a hissing sound coming from your air conditioner, it probably means that there are air bubbles in the refrigerant line. This means that there’s a leak somewhere in the system. A refrigerant leak will deprive the air conditioner of the heat transference fluid that it needs to cool your home. The result is a steady decline in output, eventually culminating in a full breakdown. If you hear hissing, gurgling, or anything similar coming from your air conditioner, you need to call for repairs right away. Otherwise, you could be replacing the entire system in the near future.
