A PROPERLY retrofitted system WILL perform as good as a R-12 system.
Retrofitting is more than changing fittings,oil and refrigerant.All the parts in the system have to be in top notch condition,a modern condenser, a compressor in great condition and the appropriate expansion device.I have done literally thousands of retrofits and the only ones that were problematic were ones that the customer wanted to cheap out on.Once all the other demons are exorcized from my jeep I plan on adding A/C and you can bet it will be an ice cold R134a system.
