This is the 2nd AC compressor unit that I have installed. My high pressure gauge keeps showing 52 psi and my low pressure keeps showing 55 to 60 psi. I replaced the dryer and it still is not blowing cold air. I check the low pressure hose to see if it was cold and it is not. I was thinking, if the previous compressor contaminated the system and clogged the expansion valve. Is that possible? And now it does not have enough circulation on the system? I got the same readings on both used compressors that I bought from the auto part store.
