Why do you think the refrigeration industry went to so much trouble to
develop nontoxic, nonflammable refrigerants in the 1920s if
propane/butane was so good?
Either stay with 100% Freon R-12 or switch to 100% R-134a. Proper
R-134a conversion at the very least consists of fixing the leaks,
switching to compatible materials (o-rings, shaft seals, dissicant),
draining out all the old oil, and adjusting the evaporator pressure
cycling switch to turn off at 4 PSI less than for R-12. But it's
better to also switch to an orfice tube calibrated for R-134a. If you
live in a very hot climate, try window tint, or install a
high-efficiency flat-tube condenser.
