I changed the R-12 compressor due to a extremely noisey clutch bearing failure. The A?C worked perfect despite the noise. After installing a compatible Harrison 134A compressor, and the necessary retro fittings etc the system is not getting cold. The line from the condenser outlet is sweating? And the suction line to the compressor is not like it should. Pressures seem to be adequate. It seems like the orfice tube(assuming it has one) is plugging but the suction pressure is 30 or so psi. Not sure if I missed something on this model. I have changed several R-12 to 134A by simply evacuating and changing the freon and fittings only.
have the same problem?
