Freon is an actual trade name, like Kleenex it wasn’t defended rigorously and now it’s used for all refrigerants generically. FYI
Comment on How would I troubleshoot an AC unit that isn't working well.

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.
