If your compressors are going bad, there is a good chance you have particles from the compressor in the system. The only way to be sure the system is clean is to flush every component very, very, very thoroughly with compressed air and a/c flush (although you can use odorless mineral spirits). While the system is open you should replace the reciever drier (this, by the way, should be the last part you put in the system before you button everything up and pull a vacuum on it. If the r/d is opened and allowed to be exposed to open air for any length of time, or installed in the car and you don't pull a vacuum immidiately, it will be wrecked), as well as install a filter on the vacuum side right before the compressor. This will catch anything you didn't get out during the flush proceedure.

Might as well through in a new expansion valve while you have the system open.
