What are Some Common Causes of Noisy Window Air Conditioners

If the blades are un balanced, they will hit against other parts of the unit creating a rattling sound. Finally, worn-out bearings in the motor can also create noise. If your window air conditioner is making any unusual noises, it’s best to have it checked by a qualified technician to prevent further damage to your unit.
