Freon is a brand name, like Sunoco, or Sue Bee Honey. The fact that it's
been improperly used for decades doesn't change that fact.

That said, refrigerant 134a has a whole different pressure, temperature
relationship. And different heat carrying capacity. If it works at all, in a
R-22 system, it won't work well.

I have a '88 Toyota that I converted over to 134a, it blows ice cold,
and I'm in Florida.
