I have a Delfield commerial cooler. It runs on R-22 with a 2500 btu compressor. The compressor might be no good, or it's possible there is a blockage in the system. I haven't messed with it yet. I was told that it does have a full charge.

I was thinking about replacing the compressor and running on R-134a. Of course a new cap line or even a TXV.

Does this sound like a good idea or not?
