How HVAC replacement costs vary in New Hampshire
State-specific code or insurance rule: New Hampshire issues no statewide HVAC contractor license (one of only a handful of states with no licensure floor), relying instead on EPA Section 608 refrigerant certification at the federal level — meaning the homeowner's primary protection against unlicensed work is the town code officer's permit-and-inspection process, not a state board.
