A/C noise

[Mr Z]

Whenever I'm running my A/C, and upshift or am accelerating relatively hard, I get what sounds like a quick belt squeak. Is this what I should be looking at, or could it be the compressor clutch?

It might just be that your belt is not tensioned enough,and the only time you hear the squeak is when the added drag of the a/c compressor is on.

Check the tension on your belt,,and perhaps just tighten the tensioner a little,,then drive it again and see if the squeak persists.

Im not sure if a little shot of spray 'belt squeak stop', would help or not,- perhaps others on here with more know-how will be able to offer better ideas,but,thats where I'd start.
Check your belt for signs of wear- little cracks at the edges.
