So the A/C compressor on car seems to be going out as it has stated squeaking and making a lot of noise. So I think it's time to change it as my car has over 200k and I believe it's never been changed. My A/C works just fine but when changing the compressor is there anything else I should change or just change the compressor.

Are you absolutely sure it's the compressor and not one of the 2 pullies? I had my compressor replaced (it was leaking and eventually went out completely), but I still had a squeel. Turned out to be the the 2 pullies and tensioner.

Here's the tensioner with new pulley:

and here's just the pulley:

The pulley will actually work on both the top and bottom, if you don't think you need to replace the tensioner. Also, I'd go ahead and replace the belt too.

I'm a fairly decent shade tree mechanic, but I let a professional shop handle my compressor swap since you'll still need to have the system discharged, recharged, etc. It was really only a couple of more hundred dollars to have it done professionally...by the time you buy all the parts and then pay a shop for the discharge and re-charge, it just seemed like the better option...

Well the belt is band new, only a few weeks old. I'm going to replace the tensioner pulley since it's kind of broken. Well I believe it is the compressor since when the A/C is of it spins slowly but it still spins and makes a hissing noise.
