Re: [DML] A/C gas types

["Mike Walsh" <mike@xxxxxxxxxxxxx>]

I am nowhere near an air cond expert. Living in Canada it is almost
impossible to get any R12. I was studying for the EPA test to get a license
so I could buy some in the US. In the "official" guide the EPA states that
if your system is R12 and is not leaking, it is preferable to keep the
system the way it is. If there are leak problems or if major components need
to be replaced then converting to R134a should be "seriously considered".

R12 is NOT illegal. It is simply not manufactured anymore. Sale of R12 is
permitted for certain uses (like auto air cond) but you must have a license
to purchase it. It is illegal to vent R12 but also to vent R134a too.

R134a can also be flammable under certain conditions.

I got lucky enough to find a garage that was able to add a bit of Freon,
it's been blowing at about 40 deg.
