I had "help" from the manager at the auto parts store who added a full R134a can upside down "cause it's quicker" (and poured liquid into the system instead of allowing the gas to be drawn into the system). I filled it 3 years ago and it has been running OK for the last 3 years, but not as cold as new. When I added the stop leak 3 years ago, there was not enough pressure in the can to fill it, but it was at a steady 40 PSI for the last 3 years so there are no leaks.
What do I do now?
I cannot get the pressure to come up beyond 32 PSI and the compressor feels slugged and rattles a bit when it turns on. I am afraid to use the AC until I get it fixed and it's hot out there! It was added on the low-pressure side, so he got that right, but clear as day it says on the bottle "to not turn the can upside down"... It's a 2013 Honda CR-V.
