Hi all, and thanks in advance for the help.
I moved into my current house 3 yrs ago, and the AC was just adequate on very hot days (say 85 deg). Last year it was less capable, and this year it is even less so. I've had it checked and charged (more or less R22 didn't really change much). It is a 10 yr old Trane XE1200, 2 ton unit, details below:
On a sunny 75 deg day, moderate humidity, it had the following condition:
Low side pressure = 90 (line a bit cold and sweaty to the touch)
High side pressure = 150 (line barely warmer than ambient temp)
Pressure when compressor goes off equalizes in 45 sec to 1 min
Compressor/condenser never too noisy or hot
Air duct inlet temp = 76
Air duct outlet temp = 65
Before I pay someone thousands to take a stab at maybe fixing it, does it seem like compressor/condenser, evaporator/orifice, or refrigerant line issue (too much oil or dirt)? I've been told different things.
