Code § 13:32A-5.1. Toms River, Brick, Jackson account for 6% of listings. See what HVAC replacement actually costs in New Jersey for the state-specific price breakdown.
How New Jersey licenses HVAC work
The license number must appear on the contractor's business documents, advertising and vehicles — N.J. Admin. Code § 13:32A-5.1. Here is how to read a license, and what the class actually limits.
The only contractor-level HVAC license
Requires 5 years of documented field experience (via an approved apprenticeship, or a relevant degree plus supervised journeyperson time) and a passing score on the Board's exam — no separate size-limited class below it.
Home Improvement Contractor registration (separate, required alongside)
Residential HVAC work legally needs both the Master HVACR license and a Home Improvement Contractor registration (prefix "13VH") from the Division of Consumer Affairs — one without the other is not enough for a home job.
- A $3,000 guarantor bond and $500,000 of general liability insurance must be on file with the Board.
- Residential HVAC work requires both the Master HVACR license and a separate Home Improvement Contractor (HIC) registration — check for both, not just one.
- Minimum efficiency for new equipment: 13.4 SEER2 for split-system air conditioners (DOE North region, 2023 standard) — the lowest of the four US regions, reflecting New Jersey's shorter cooling season relative to Texas, Florida and California.

Answers specific to state rules. City pages add the local permit and utility details.
Is a Master HVACR license enough to hire someone for a home job?
Not on its own. New Jersey requires residential contractors to also hold a Home Improvement Contractor (HIC) registration, a separate credential from the Division of Consumer Affairs. A legitimate residential HVAC contractor in New Jersey should be able to produce both numbers, not just the HVACR one.
Why is the efficiency minimum lower in New Jersey than in Texas or Florida?
New Jersey sits in the DOE's North efficiency region, which has a shorter, milder cooling season than the South or Southwest regions — so the federal minimum (13.4 SEER2) is set lower than the 14.3 SEER2 required in Texas and Florida. A lower minimum isn't a lower-quality standard; it reflects genuinely different climate demands on the equipment.
How do I check a New Jersey HVAC license?
Ask the contractor for the license number and search it on the NJ HVACR Board lookup (official site). Every verified profile on AirProHQ links straight to it, with the number already on the page.
Why is one New Jersey city mostly verified and another isn't?
It reflects how each listing reached us. Listings pulled straight from the license register verify at very high rates; listings that came from permit filings or public business profiles stay unverified until we can tie them to a license. A low share is a data gap, not a warning about the city.
