(Just because the chemical name ends in "methane" doesn't mean it's flammable.) It is illegal to *produce*, not to use. You may be confusing some posts in which people have mentioned the replacement of R12 with propane, which has similar condensation and evaporation properties and which *is* flammable (and absolutely should not be used in an AC system). > I have got the above pro's and con's correct. What should I go for? You will get half a dozen responses telling you to stick with R12, because it's what the system was designed for. They're probably right. However, I filled mine with R134a because I had it on hand, and my AC works quite nicely even in Houston.
