The lines and seals need to be replaced. 134A runs a much higher pressure than the old R-12 did. MUST change the lines. I am sure there is an anomaly to this statement, but the best approach is to replace as much hose as you can.

> Small refrigerant leaks are usually hard to find and often harder to fix. Automotive systems leak a lot due to multiple connections, hoses, and the fact that the compressor has some type of shaft seal. Yes R-134a can leak out older style hoses faster that R-12 but since the R-12 did leak out that problem needs to be addressed. While everyone looks at hoses and compressor for leaks it also common for the evaporator and condenser to leak. Condenser leaks often occur between on the radiator side. Very difficult to find. You need a sniffer or take it out and look for the oil stain. Same for the evaporator. The duct work has to come down. The expansion valve can also be a leaker.

I figured I had nothing to lose by playing with it so tried one of the cheapo R134a conversion kits from an auto parts store. That worked to cool things down. I suspect a leak somewhere since I must recharge annually, but that is very little trouble for the real benefit it provides.

Good luck!
