Superheat should be 8 to 12 degree's. Sub cooling around 18-22. I like to use superheat that way I know the coil is doing all it can do.

R22 systems should run a 68# to 70# suction pressue. If you look at the suction guage at 68# that is a 40 deg evaporator coil temp.

Goodman CLJ36-1A with bad Copeland Compressor CR30K6-PFV. Any suggestions where to get a replacement compressor?


Not a DIY project. You'll need refrigerant recovery equipment, vacuum pump, manometer, refrigerant scall, refrigerant disposal bottles, high pressure nitrogen tanks and regulators, acetelyn tanks with regulators and torch tips not to mention EPA license. Call a reputable service company. In South Central PA, fair price range is $1,500 - 2,000. If the unit is more than 10 years ole, replace the condenser (if they can get one for your refrigerant) for about $1000 more.

System not cooling space it cooled once before?


Hi, could be compressor loosing efficiency, i think suction pressure is to high at 85, also it could be moisture in your system, did mechanic replaces filter drier on high side of system , when he replaces evap. install filter drier on liquid line, if there isn't one, also check compressor valve, you can do that by cutting or desoldering the high side from compressor, connect charging port to compressor, conect your gauge charging port, start compressor, pump up to between 150- 200 psi shut off gauge, and leave for about 1 hr. then check pressure, if pressure decreases, then your compressor valve are leaking, if it maintain same pressure, then compressor valve is o/k. you can do same on suction side, this time in vacuum, if it holds vacuum pressure, then valve is o. k, RLA(LRA) lock rotor amps, is amount of amps compressor used to start, but will drop once compressor is running, 11.6 when operating is o/k, does your evap. compatible with condensing unit?, is it right size. check also that you're using right type of freon, check condensing unit & evap labels for right type of freon, make sure they can handle same type of freon. but check compressor valve carefully, i think your comperssor could be loosing it efficiency, compressor could be your problem. good luck.good luck
