If your system is properly prepared with the proper seals, suction valve,
dryer, compressor seals and hose the R134a will work as well as the R12.
Horse pucky! 134a is 20 percent LESS EFFICIENT than R12
Its a FACT that if you convert an R12 system over you will loose cooling
ability
Unless you are willing to re engineer the system with larger condenser etc.
It's sad that simple freon has been outlawed 134a has huge environmental
problems that R12 never had.
