Re: AC Condensor fittings size

Thanks again for the help guys. I did some more research and discovered a few things. To check the POA valve you disconnect the vent fan and watch the pressures. I could see my POA cycling at about 26 psi, so my 3/4 turn method worked pretty good. POA valve set for 134a. Then I checked my pressures again with the fan on. Low side was a little low, high side a little high. I added some more 134 and my low side went up slightly. I also raised the rpm's and my low pressure dropped and high pressure increased. From my research it looks as though I may have too much oil in the system. This is very possible since I'm not sure how much oil was in the compressor when I began, I added about 7 ounces. I also had a mishap in the middle of one of my Freon adds so I can't say for sure how much I have in, but most likely too much. Here are my pressures if anyone wants to confirm or deny my findings.

41 psi low - 255 psi high - 65 vent temp - med fan - 80 degree day
35 psi low - 275 psi high - @ 1500 rpm

I'm a windows down guy anyway so this is no great loss to me, I just like things to work.
