Update to a/c R134a retrofit from May 8th:

I have received several e-mails from list members,
asking about the cooling performance of the
R134a refrigerant. I measured the temperature
of the cooling air at the a/c vents in the back
in the camper. It showed 42 degrees Fahrenheit.
I haven't noticed a temperature difference between
R12 and R134a. But, of course, my R12 never
seemed to work for very long.
It sure is a lot less costly to recharge with R134a,
compared to R12.
