Well.. I'll give you one guess..
We hooked up the pressure guage, observed the low reading, added more R-whatever it took, and from then on it worked perfectly till the next time it needed a re-charge (or till it's end of days whichever came first)
Do you know of another way to do it? I don't.
Depending on the unit in question "WE" either refers to a professional Air Conditioning serviceman, with me watching, or myself.

Well, WRONG. To attach a a gauge meant you HAD to tap into the system. The CORRECT way to determine a Charge state is, you connect a digital amp gauge and take a amp reading after 15 minutes and the amp reading is based on the ambient temp and the amp draw listed on the AC spec plate. The amp draw is temp biased depending on the ambient temp. There is NO other way to do it on a RV AC roof air as they are ALL sealed systems. He was NOT a professional RV AC unit Serviceman if he did not know to do it this way. Doug

Well, my edits I did above in red explain this reply.
"R-whatever it was"?
"till the next time it needed a re-charge"?
"Professional"?
Sorry, but reading these statements, there is obviously no-one that was professional that worked on these units.
A competent service man would know that R-22 is what is used in a roof-air and would know that if the unit was low on refrigerant, there had to be a leak that needed to be addressed so it wouldn't need to re-charged again.
And BTW, the now Federal laws governing the release of refrigerant into the atmosphere prohibits a mechanic, especially one with an EPA license, to knowingly allow a refrigerant system he has worked on to continue leaking refrigerant and to place back into operation any equipment that they know has a leak.
Not trying to be a wise-a@* here but facts are facts and since many that read this Forum take posts here as "gosple", they need to know the CORRECT facts.
