My AC has been very cold for the last 5 years, but now it's apparently low on R12 since it's not cooling well and the compressor is cycling a little bit at idle. Once I find and fix the leak or problem, what should I recharge it with? I would prefer R12, but since R12 is apparently made from diamonds now days, I'm looking into everything else first.
R-134a is out, not going to happen here. So, that leaves HC12a, Freeze 12, and R416a. Did I miss anything? Folks are telling me that HC12a is flammable, freeze 12 is tough on compressors due to oiling, and R416a is still not very well known, but looks the best so far. All this comes from commercial AC guys that I know, so they may or may not be up on automotive stuff.
Any experts here?
