A/C performance
It's hot, and while the A/C in my 80 is working I'm not sure that it's doing as well as it should.
There is definitely gas in the system: I can see fluid in the sight glass, and hear the evaporator hissing away.
The pump is definitely pumping: high pressure pipe is hot, low pressure cooler, sight glass shows fluid flow.
I had a leak fixed and the system regassed about 2 years ago.
And it is definitely cooling air ... but just not as much as I'd like and, more to the point, less effectively than I remember. But that's a very qualitative judgement.
Is there any simple way of measuring its efficiency, and estimating whether or not I need to take some action?
