Air conditioner stopped working today. I bought a canister of r-134a with a guage on it. When I hooked it up, the pressure was in the red zone. I emptied the system and brought the pressure back up in the system to around
40 psi. It took about an hour and the air was not cool again. A second check of the pressure had it in the red zone again (like 100 psi).Any idea what the probem is?
What can I do to fix it?
