check these number
OK I got a chance to change the filter drier today and basically got the same numbers. I added more R-22 to see if I could get about 15 degrees of subcool. The factory charge is 6.38, but I do have about 45 feet of line set. I put a total of 7.5 pounds and got these numbers
ODB 38 IDB 72
vapor 298 150 degree
liquid 80 77 degree
according to the charts I should have about 218 and 48; so I am close on the suction - makes me think the charge is correct, but once again look at the subcooling and the vapor line. WTF? Its like the inside coil is not rejecting the heat. Once again I checked the filters and fan, I did not check the coil because it was cleaned not to long ago.
Thanks for any help you can give
edit- forgot to tell you when I did open the lines, I blew nitrogen from one side to the other then did a triple vac.
