Solution to a Noisy Air Conditioner

Air conditioner compressor noises are generally disheartening. Here are some of the solutions to solve this problem.

Noisy Fans

If the fan is not working properly, it will need to be cleaned and maintained properly. Fans that produce a humming or rattling noise may be loose or need some cleaning. All you have to do is open the ac unit and locate the fan. Remove any obstacles or debris that may have found their way into the fan.

If debris is not the problem, check the blades to see if they are loose and ensure they are straightened. If they are loose, tighten the screws at the hub. On the other hand, a slight bend on the blade may touch the inside of the unit thus producing a disturbing noise.

Loose Bolts and Screws

Once the air conditioner is running, it produces some form of vibration that cause the screws to come loose. The result is a rattling noise on turning on the air conditioner. This can be fixed by tightening the screws and bolts with the help of a screw driver.


The motor in the AC unit needs regular lubrication. If it is not lubricated, it may emit a grinding or humming noise. Some ac units come with unsealed motor making it easier to apply the lubrication in oil form. You can make it a routine to oil your conditioner at the onset of summer.
