Noisy A/C

I am also in the process of tracking an AC compressor noise. I get mine above 3200 rpm and it stays until I let the rpm's fall back down to 2800 or so. Then all is good until I exceed 3200 again. Not there if AC is off. I assume it is the clutch assembly of the compressor drive, but I suppose it could be internal to the compressor. Haven't had time to drive over to my AC man. But I doubt he services the clutch unit and will want to install a rebuilt/new compressor. The clutch units can be bought separately, and I have seen clutch removal tool sets on eBay.

Hope this helps you at least a little bit.

Larry....the info helps alot.I thought it was an internal problem, didn't think about the clutch. I will call a few a/c shops and see what options are available. Thanks #7260

I have the same 3200rpm noise issue. If you figure it out please post the answer.
thanks Rick

You didn't describe the noise but if it is a high pitched shriek it is the idler bearing. They are just a roller bearing but have no means of getting lubrication. What happens is the get sticky and cause the fan belt to slip as your air conditioner loads it up. They are cheap and you can get them at the parts store. All you have to do is look at your belt to see if it looks like it has gotten real hot.
