There are, and that’s the way the average joe is supposed to do one of these. Technically speaking you can’t even hook up a refrigerant manifold to a system legally without an EPA 608 cert (assuming you’re in the US). Of course the EPA doesn’t exactly have the funding or support to enforce anything right now. Even if they did, they have far bigger fish to fry than a homeowner doing their own HVAC work.
Of course, if you do want to work with refrigerants more then an EPA 608 cert is prettyeasy to get. It’s a lifetime cert and I was able to get it with a week of self study and an online test. 608 type 2 is what you need for most HVAC but really it’s not that much harder to just get the universal cert.
