Q: AC making clicking noises upon startup.

asked by on

The AC is making a clicking noise when I start the car.

There are a lot of components in the AC system that could cause a clicking noise. The AC compressor clutch makes a clicking noise when engaging, which is normal. My guess is that this is what you are hearing. A trained professional, such as one from YourMechanic, will be able to listen to the noise and give you a proper diagnosis.
