Squeaking/chirping noise - ? Ac compressor

Van has been squeaking / chirping for last couple of months, gradually getting louder. It's most noticeable when idling but I think it's still there when driving just drowned out by engine noise.

My local garage changed the auxiliary belt but it hasn't made any difference. After a lot of head scratching they *think* it's something to do with the AC compressor but they don't seem very sure and quoted £600 to replace. The noise happens regardless of whether my heating/AC/cabin fan are on or off. Has anyone else been in this situation and solved it before I drop £600 on a fix which may not work?
 
Similar; however mine was the cam belt idler pulleys.


It would be easier to rule the A/C compressor in or out by running the engine with the aux belt removed. I'm surprised they didn't do that. Belt off, no noise etc..
