Warning sounds are one of the major ways that you can tell your home’s air conditioning system is in need of repair work. There are many kinds of cautionary sounds like this: hissing often means losing refrigerant, clanging indicates loose mechanical parts, and clicking can mean a failing capacitor or a hard-starting compressor.
In this post, we’re going to look at a specific warning noise, which is a mechanical shrieking/screeching sound. No matter the volume of this sound, it’s something you must take seriously. Call for repair technicians right away and let them look into the problem as soon as you notice the sound.
What This Noise Means
This shrieking sound is a problem with one or more of the bearings in the motors. An air conditioner has a number of motors to operate their fans and compressor. A number of different problems can lead to one of these motors failing, but the main cause of motor failure—and this applies to any motor at all—is bearing-related problems.
Bearings are responsible in motors to reduce the friction of the moving parts. Essentially, the bearings “bear the load” of the moving parts of the motor to prevent damage. But the bearings in a motor can wear down like any other mechanical component. When the bearings in one of the motors of your AC start to wear to the point of failure, it will create a screeching/shrieking noise.
It’s important not to ignore these sounds, because if the bearing fails, its motor will be at a high risk of breaking. It’s much easier (and less expensive) to replace worn bearings and rescue the motor than it is to replace the entire motor.
