R12 or R134
I was just about to remove my AC system and then I realized that the compressor is an aftermarket. Is there a easy way of telling if I have the R12 or R134 system? Because if it is a R134 system I'll just check it for leaks and recharge it. If it is the R12 system I'm going to remove it.
Thanks, Bill |

If the conversion was properly done there should be a R134a label and a high pressure cut out switch on the high pressure side (side with hose going to the condenser) on the system. In addition to that, the correct R-134a charging fittings will be of two different sizes (high and low pressure are different) and have a red and a blue cover or cap respectively on them. However, who knows? A "Dukes of Hazard type" could have filled it with Coleman stove propane. Pro A/C shops have this trouble all the time, hence their use of refrigerant sampling units. Perhaps you should have such a shop check it for you. Cheers, Jim

Thanks! It looks like it's an R12 system then, but I'll run it by a shop just to make sure.
