Yesterday I got a wild hair and decided to refill my a/c system. The previous owner had put r134 in the system, who knows if he did anything else to convert it. My York looks like it might be a rebuilt unit though, fresh paint, clean and just looks like the newest component under the hood.

Anyway I checked the York’s oil level, hooked up the gauges and dumped a can of 134 in. This brought the high side up to 140 PSI and I was getting cold air! No bad noises, no huge drop in engine RPMs just cold air. My happy moment was short lived though when I noticed oil was leaking from the bottom on the compressor at a rapid rate so I shut it down. I kept leaking I am guessing until all the r134 pressure was gone.

Can you still get gasket sets for these?

Would it leak pressure from the bottom plate on the unit?

Should I just skip repair and go for a Sanden retro fit?
