Q: Air conditioner compressor makes noise

asked by on

The air conditioner compressor unit (pulley) is making noise, and the serpentine belt tightens and breaks.

Hello. The way to correct this problem is to simply replace the A/C compressor unit in its entirety, along with the serpentine belt. The other pulleys need to be checked as well, to make sure they are not causing problems. I suggest you have a certified technician, like one from YourMechanic, come out to run an inspection on your AC system.
