If anyone knows the unique sounds that your air conditioner makes, it’s going to be you. There’s no such thing as a completely quiet air conditioner. However, that doesn’t mean you should ignore it when there are excessively loud or strange noises coming from your cooling system. You should be on alert for any unusual noises you haven’t heard before.
Odd AC system sounds typically indicate an issue that needs to be resolved ASAP. Read on to learn about two of the most common air conditioner noises that prompt the need for professional repairs.
Hissing or Bubbling
Sometimes described as a bubbling sound, hissing coming from your AC system is not normal. In most cases, it’s the result of air bubbles existing within your refrigerant line. What this means is that you have a leak occurring within this line, and the output of your air conditioning system is going to rapidly decline.
This is not a problem that should ever be ignored, as your air conditioner can eventually break down entirely if neglected for too long. As soon as you notice this ominous sound, you’ll want to shut your system off and call for repairs. Refrigerant leaks need to be sealed, and refrigerant must be replaced to restore the full function of your air conditioning unit.
Grinding
One of the many components housed within your air conditioning system is the air handler. Your air handler functions by moving air throughout your home during its operation. This component is comprised of a large motor with a fan attached to it. During its operation, a lot of stress is placed on the air handler, and therefore it has a series of lubricated bearings to help it do its job.
These bearings are necessary to assist your air handler in operating smoothly and help your AC system work more smoothly overall. However, like any other component, they are going to wear down over time. When this happens, the friction on the air handler increases and produces a loud grinding sound. If you hear this noise, be sure to call for repair services ASAP.
