Listen for These Air Conditioner Noises

The more you rely on your air conditioner to keep cool this summer, the more strain is going to be put on the system. That means it will be more likely for problems to occur. Quick response time is vital when it comes to preventing damage to your air conditioning system, so it’s a good idea to know the signs that you need to call for repairs. Read on for more information on some of the common sounds that indicate a problem with your air conditioner.


The air handler is the part of the air conditioner responsible for actually circulating air during operation. In order to cope with the massive amount of friction that the air handler motor generates while it’s running, the system is equipped with a number of oiled bearings. These bearings wear down over time, causing the friction on the air handler motor to increase and creating a loud grinding sound during operation. If you hear this sound, call for repairs right away. Otherwise, there is a very real possibility that the air handler motor will overheat and burn out.


Hissing, bubbling, and similar noises often indicate air bubbles in the refrigerant line, which means that there’s a leak somewhere in the system. Air conditioners cycle refrigerant through their systems during operation, in order to move heat out of the home. A refrigerant leak will drain the air conditioner of the fluid it needs to operate, causing a steady decline in output followed by a complete breakdown. If you hear this noise, or see liquid dripping from your air conditioner, call for repairs right away. Otherwise, you will be paying a lot more in repair costs down the road.
