I have my own small company and I know I shouldn't have done this but I'm kinda stuck now. I have a carrier condensing unit Model 38TRA060330 R-22 and bought a ADP 13 seer, changed out txv vale to R-22 but having major screwed up readings on gadges. 250 on high side and 60 on low side . Its a Copland scroll model zr57-k3-930.Txv valve is 5ton, indoor coil is 5ton and out unit is 5 ton. Cant even get to do a supper heat or anything because it seem like the compressor goes into some internal dump mode. not sure what to do. any suggestions?
