How do I convert a R12 to R134A for my AC system?

처리 내용

Checkout the Auto AC board at AC Source There are some good people on there. Don's right. You do need to flush the old oil out of the system because they don't mix. Also it's difficult to flush the compressor so odds are it will not last if you don't replace it. The best thing to do is change the compressor out if its older at the same time, replacing all the o-rings too. R134 operates at higher pressures and it won't be as efficient, so you have to be careful not to overcharge. Older condensors designed for R12 might not cut it.
