What You Need to Know About Car AC Compressor Noise When Engaged

The car AC compressor noise is the sound produced when the air conditioning compressor is engaged. This sound is typically a loud, whining or buzzing noise that can be heard from within the car’s cabin. The noise is caused by the compressor’s internal components vibrating as it cycles on and off in order to cool the air. This noise can be minimized by properly maintaining the car’s AC system and checking for any issues with the compressor or other components. Additionally, some cars may have a sound dampening material that can be installed to reduce the noise of the AC compressor.
