If Your Air Conditioner is Making These Noises, Call for Repairs

Dependable Service Since 1926

With the weather heating up, you’re going to be relying on your air conditioner more and more often. More demand means more wear and tear on the system, which means it will be more likely to develop problems. You need to be able to identify possible issues with your air conditioner early if you want to keep the system from becoming damaged. One of the most common warning signs that your air conditioner is in trouble is strange noises coming from the system.


A grinding sound coming from your air conditioner is probably the result of a problem with the air handler. The air handler is the part of the system responsible for circulating air throughout the house during operation. Inside the air handler motor are a number of bearings, designed to reduce friction on the system while it’s running. These bearings wear out over years of use, causing the friction on the system to increase and a grinding sound to occur. If you hear this sound, call for repairs as soon as possible. If the bearings are not replaced in time, the air handler motor could overheat and burn out.


One of the most dangerous problems that can affect an air conditioner is a refrigerant leak. Air conditioners do not consume refrigerant, and rely on the same amount that they receive when first installed for their entire lifespan. If a leak develops in the refrigerant line, it will cause a steady drop in output followed by an eventual breakdown. A hissing sound indicates that there are air bubbles in the refrigerant line, which means there is a leak somewhere. Call a professional immediately if you hear this.
