One of the features of a modern air conditioner is its quiet motor. If your air conditioner is too loud, the type of noise it is making may help you diagnose the problem. Here are some common noises and the possible problems they may be causing in your air conditioning unit. If you aren’t sure what the problem is, your best bet is to contact a licensed air conditioner technician to diagnose the problem.
Rattling noises may indicate something as simple as a loose bolt on the air conditioner cover plate. It could also mean that something has come loose elsewhere in the unit. Flip the power off at the breaker before removing the cover from the box and checking for loose screws.
Air Conditioner Sounds and Problems
Thudding sounds indicate that something has come loose inside the air conditioner while it is attached to the motor. This could be the fan blade, a plastic component, or a cover plate. To find out, remove the cover plate and perform a visual inspection for the loose object.
Screeching when the unit turns on to blow air or cool the air down would be an indication that the serpentine belt of the air conditioner’s interior motor has begun to wear out and stretch. You will need to have it replaced.
Whistling sounds indicate that seals are not performing properly. Check the ducts in your home for loose connections and tighten the bolts and screws. Make sure that any heat tape used to cover the seals is completely adhered to the duct seams.
