I'm have a strange problem with my A/C. Sometimes it will suddenly stop blowing cold even though the compressor is engaged. It's not an icing problem because sometimes it will start out only blowing warm air. Other times it will blow cold for a period of time then stop...or not.

It's 78 Eleganza II and I've just replaced the compressor and charged the system with DuraCool. System was working fine when last used but had leaked down through compressor seal several years ago and although the engine and generator has been run periodically, not so with the A/C. System was 134A before the compressor swap and was evacuated overnight and let sit for hours with no leaks after the swap.

Low and high side pressures are fine when running but haven't caught it blowing warm with the gauges in place but will keep trying. Is there any kind of vacuum control on the compressor?
