Comment on How would I troubleshoot an AC unit that isn't working well.
givesomefucks@lemmy.world 2 months agoYou also can’t buy refrigerant without a license.
That’s gotta depend on location…
I’ve lived in a couple US states, and AutoZone always carried it.
Just checked online and even amazon sells 134a

134a is for automotive ac units. Unless something has changed recently, household hvac systems use a different type. It used to be R22 for both, but that was a long time ago. Turned out freon (R22) was bad for the environment.

They’re pretty much all bad for the environment, just to different degrees. Even the “greener” refrigerant choices (which have suboptimal thermodynamic properties, BTW) are things like ammonia, carbon dioxide and propane.
Point is, don’t be cavalier about letting your refrigerant escape even if it isn’t R22.

Freon is an actual trade name, like Kleenex it wasn’t defended rigorously and now it’s used for all refrigerants generically. FYI

Didn’t know that. Thanks!
