Do your own heat pump HVAC work?

Interesting topic. Looks like things all changed just over a year ago. Not clear what fines are against the buyer; what I have found is fines on sellers failing to verify certifications. And that still leaves legally handling the 'freon' which is different regs.

Looks like you can get your 608 certification.....I've found online courses and tests.

Not sure what the licensing requirements are in your state however; that is a matter entirely separate from EPA cert's and regs.
