I have a slow leak in one of my units, a couple of lbs per year
I have been getting help charging it and decided to get my own gauge.
The inside green scale is labeled R22, it maxes out at 70 where the outside line reads 115
I checked my unit that has never been recharged and it read approx 63 on the green and a little over 100 on the outside
I put in 3 cans of R22a from Envirosafe and after the second can the water poured out the drain as the coils thawed. After the third can it read around 64green 104 outside line.
Outside temp was approximately 97°F
Neither unit is very cold inside, I don't have a thermometer to read the outlet air, but it cannot be much under 70, the house climbs into the 80s with AC on all the time, never drops to low 70's until around 4am.
Are they both overcharged?
The last guy who was a tech and serviced it complaineded that the new guys never charge these units high enough so they never really get cold.
I assumed (yea I know) that if I matched the two, I would not overcharge the one I was working on.
Both units were new with the house and are about 7 years old
hot in SC
