Checking A/C freon pressure

[cjracing15]

I am a refrigertion service man by trade. If ( and it is a big IF) you did not lose any freon the only way to save it is to recover it. To do this you will have to find someone that is epa approved to handle R-12, and also have a recovery machine to recover your R-12. If it was mine I would bite the bullit and swap to R-134A. R-12 is the best refrigerant for cars and trucks BUT, it is to hard to come by and to EXPENSIVE to use. Just my two cents.
