 Texas/New Mexico Stateline | You said: "tightened some fittings and added 3 cans of freon."
Was the system completely drained at that point? If it was you should have pulled a good vacuum before adding refrigerant. With somewhat normal pressures, and poor cooling after a system has been messed with I would suspect it has air mixed in with the freon. Or the heater valves leaking, which you already checked.
I would break it down myself and change the expansion valve and drier for good measure and evacuate it good before charging it again. |
