|Some new numbers here... Still a little cool outside, but not much I can do about that.
Inside/Outside ambient: 74F/76F
Lo/Hi Pressure: 57psi/205psi
Pressures converted to temperature: 34F/112F
Suction line temp at compressor: 53F (19F superheat?)
Temp at nearest indoor vent: 55F
I've also noticed the compressor is quieter than the fan now. It's now sounding about the same or a little less noisy than before all this happened.
Total refrigerant added - about 5.5lbs of ES-22a.
So now the question is "what caused all this?" 20+ years of very slow leak (bad service valve/cap?) or something less slow and more recent? The service caps on this unit are brass with no seals. I'm told they tend to be leaky, which is presumably not a good thing. When I removed the hi side cap, it gave me a little PSST, so sounds like the valve was leaking at least a tiny bit. Perhaps the question is, was the cap leaking a little too? I plan to leave the gauges hooked up for a couple of days to keep an eye on things. Might new caps be a good idea anyway, just as general preventative maintenance?
Thanks for any clues...
