R12 is neither illegal nor is it flammable.  (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).

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.  YMMV.
