How New Jersey licenses HVAC work
HVAC contractors are licensed by the state.
License types: Master HVACR Contractor.
Companies: Under N.J.S.A. 45:16A-7 (P.L. 2007, c.211) a person may not work as a master HVACR contractor, or use that title, without a license from the State Board. The statute defines HVACR work to include installing, servicing, maintaining or repairing boilers, hydronic heating, furnaces, warm-air heating, refrigeration and evaporative cooling, ventilation and exhaust systems, gas piping on the load side of the meter, and pneumatic controls. The Board's FAQ says it issues one license type, the Master HVACR Contractor license, and does not license companies. Exemptions listed in the act include owner-occupants working on their own home (CFC/HCFC refrigerant work excepted), regulated utilities, and licensed architects, engineers, electrical contractors and master plumbers working within their own scope.
Local rules: The act says a municipality, local board of health or other agency may not issue or renew a Master HVACR contractor's license (N.J.S.A. 45:16A-6), so the license is statewide only. We did not research municipal construction permit rules.
Check a license: newjersey.mylicense.com
Search the contractor on the Division of Consumer Affairs license verification page (license type 'Master HVACR Contractor') and confirm the license is active; the Board's rules require licensees to show their license number on vehicles, advertising and websites.
Federal rule: in every state, technicians who handle refrigerant must hold EPA Section 608 certification, whatever the state or city requires.

Before you hire
Ask for the license number and check it on the official lookup where one exists. Ask for proof of insurance and a written, itemized estimate, and ask who pulls the permit if the job needs one – a new furnace, heat pump or air conditioner usually does.
