STATE LICENSE
RequiredNJ State Board of Examiners of Master HVA…
The HVACR Licensing Act (P.L.2007, c.211; N.J.S.A. 45:16A) bars anyone from working as or using the title of Master HVACR contractor without a license. Applicants must be at least 21 and show five years in the HVACR field, at least four of them in a USDOL-approved apprenticeship or training program — or a bachelor's in HVACR technology plus one year, or any bachelor's plus three years supervisory experience.
Unlike New Jersey's plumbing board, the HVACR act writes an insurance floor into statute: general liability of at least $500,000 combined per accident. The same board also licenses Master Hearth Specialists. Homeowners working on their own residence are exempt except for CFC/HCFC refrigerant work.
The state sets the license floor; the county or city permit office controls filing, inspections, and local rules wherever the job site sits.
The license is statewide; mechanical permits and inspections come from municipal construction offices under the Uniform Construction Code. Licensed HVACR contractors working within their scope are exempt from home-improvement registration.
The local offices section below names the exact permit desk for every New Jersey county on file.
Each row names the issuing authority, cost, timeline, citation, and status behind the requirement — verified against the official source.
Published fees from the issuing authorities, as of October 2026. Local permit fees vary by project and jurisdiction — the basis is stated where a flat number does not exist.
The $500,000 general liability floor is written into the HVACR act itself, not left to board policy.
A bachelor's in HVACR technology plus one year, or any bachelor's plus three years' supervisory experience, substitutes for the five-year field path.
Master HVACR and Master Hearth Specialist licenses carry identical fees: $100, $160/$80, $160 renewal, $50 late, $150 reinstatement.
