My car has the dealership installed VPC AC. I purchased the car 5 months ago and the AC doesn’t blow cold. I have no history on it. Still had a little pressure in the system. I’m thinking of charging it with R134. Has anyone done this and know how if it will work and how much I should try to put in the system?

R134 molecules are smaller than R12 molecules and they leak out through the old hoses, even if the old hoses were new the R134 would leak out through them. This is why you need new barrier hoses.
R134 is also not as thermally efficient as R12, so a R134 system has to be bigger to provide the same cooling capacity as a R12 system. This is why an additional condensor or a larger condensor is needed. The rotary compressor also moves more freon with less load on the engine than the York piston compressor. R12 systems are expensive to upgrade but they are also expensive to maintain. R12 is probably $50 a pound and the system has to be serviced by a licensed tech (at least in CA). Jim |
