Comment on How would I troubleshoot an AC unit that isn't working well.

  You 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

  Quick Google search I found a website that let you buy it all you have to do is check a checkbox that says your certified.

    Not legal and definitely not easy to get local without a license. There’s always someone will to sell on the black market. Also, shit is dangerous if you don’t know what you’re doing. I was trying to give the OP sound advice, you know, what they’re asking for.

      The fact it’s so easy to obtain without a license online is wild. You wouldn’t think it would be in the top search results.

        You can buy all the toxic chemicals you like, online or at the hardware store

    Totally. Then once you get it, make sure to huff a bit of it to make sure it’s pure

      Nonsense. You pour two fingers and slam it then immediately shotgun a beer. It’s the only way.
