    I beleive the compressors have a clutch on them, so they only engage when the air con is switched on.

    ignore that removal advise, that refers to mine where i have already disconnected the aircon system. You will need to go to an aircon place with your new compressor and have them swap it for you as they need to dispose of the chemicals/gases properly and then refill it afterwards.
