Thankfully, the training is only required if you're doing the installs for/as a business.
I think in pretty much every state releasing the refrigerant 'requires' a license (if it's not a DIY model).
And in my state, I copy pasted what was required for a 'residential' HVAC license (idk if you meant commercial HVAC or just making money on installs).
