How to choose a HVAC contractor in Bergen County
Start with the license. New Jersey requires heating, ventilation, air conditioning and refrigeration work to be done under a Master HVACR Contractor license, and the license number must be shown on the company's vehicles, invoices and ads. Look it up on the state's license lookup before you let anyone open up your system.
For a repair, ask what the diagnostic or service-call fee is and whether it's credited toward the repair. For a replacement, get at least two written quotes that name the equipment (brand, model, capacity), say whether ductwork, venting or a new thermostat is included, and say who pulls the permit. Swapping a furnace, boiler or central AC for a similar unit is still permit work in New Jersey, even though the work can begin once the town has been notified.
Be wary of a quote that's much bigger or smaller than the others without a clear reason. A good contractor will explain why a system should be repaired or replaced, sized to your house rather than to whatever is on the truck.
Questions to ask
- What is your Master HVACR license number?
- Is the diagnostic fee credited toward the repair?
- What exact equipment are you quoting, and who pulls the permit?
- What warranty covers parts and labor, and for how long?
Red flags
- No Master HVACR license number on the van, invoice or ads (N.J.A.C. 13:32A-5.1).
- Offers to skip the permit on a furnace, boiler or AC replacement. Like-for-like swaps are minor work and still need a permit (N.J.A.C. 5:23-2.17A).
- Quotes a larger or different-capacity system but treats it as a simple swap. Only like-capacity replacements qualify as minor work (N.J.A.C. 5:23-2.17A).
- Can’t show its $500,000 general liability insurance. The licensing law requires that minimum (N.J.S.A. 45:16A).
- An unlicensed worker handles refrigerant (CFC/HCFC) work. Even the homeowner exemption doesn’t cover it; it must be done by a licensed Master HVACR contractor (N.J.S.A. 45:16A-9).
New Jersey licensing
What to check: New Jersey Master HVACR Contractor license. It appears as “Master HVACR contractor license number” or “Master HVACR contractor Lic. #” on vehicles, invoices and ads. The number’s format was not confirmed.
New Jersey’s HVACR licensing law (P.L.2007, c.211; N.J.S.A. 45:16A) bars any business from HVACR contracting unless it is authorized to act as a Master HVACR contractor. The company acts through a licensed bona fide representative (its owner, partner, LLC manager or corporate officer). The Master HVACR contractor’s pressure seal must be on every HVACR permit application. Licensees must carry at least $500,000 in general liability insurance and a $3,000 surety bond. The license covers furnaces, boilers, hydronic heating, air conditioning and refrigeration, but not equipment used only to heat potable water. Vehicles, invoices and ads must show the license number (N.J.A.C. 13:32A-5.1). To verify, use the license lookup (profession “HVACR”).
Permits
Replacing an existing furnace, low-pressure boiler, air-conditioning unit or condensing unit with new equipment of like capacity is minor work under the Uniform Construction Code. A permit is required, but work can start after notifying the local construction office, and the application is filed within five business days (N.J.A.C. 5:23-2.17A). Repairing or replacing ductwork and controls, repairing AC equipment, and replacing motors, pumps or fans of the same capacity are ordinary maintenance with no permit (N.J.A.C. 5:23-2.7). New systems, or equipment that changes capacity, need a regular permit before work begins (N.J.A.C. 5:23-2.14). Permits come from your town’s construction office, and each municipality sets its own fees by ordinance (N.J.A.C. 5:23-4.17).

Common questions
Do I need a permit to replace my furnace, boiler or central AC in NJ?
Yes. Replacing an existing low-pressure boiler, warm-air furnace, AC unit or condensing unit with new equipment of like capacity is “minor work” under the Uniform Construction Code. A permit is required, but work may begin once the contractor notifies your local construction office, and the application must be filed within five business days. An inspection follows. Installing new or larger systems needs a regular permit before work starts. (Source)
Who is allowed to install HVAC equipment in New Jersey?
A business doing HVACR contracting must be authorized as a Master HVACR contractor under the state licensing law, acting through a licensed bona fide representative. Single-family homeowners who live in the house may do HVACR work on their own home once they have the required permits. Work involving CFC or HCFC refrigerants must still be done by a licensed Master HVACR contractor. (Source)
Is a water heater an HVAC job or a plumbing job in NJ?
New Jersey’s HVACR licensing law excludes appliances used solely to heat potable water from its definition of HVACR. Under the Uniform Construction Code, replacing a water heater with one of like capacity is listed as plumbing minor work, so it needs a permit. In practice, hire a licensed master plumber for a water heater and a licensed HVACR contractor for heating and cooling. (Source)
Do I need a permit for duct repairs or a new thermostat?
Generally not. The Uniform Construction Code lists repair and replacement of ductwork, repair of air-conditioning equipment, repair or replacement of heating and AC control devices, and replacement of motors, pumps and fans of the same capacity as ordinary maintenance. Ordinary maintenance needs no permit, inspection or notice to the construction office. Rearranging the heating piping system is not ordinary maintenance. (Source)
What insurance and bond must an NJ HVAC contractor have?
Under the HVACR licensing law, a Master HVACR contractor must keep, and file with the state board, general liability insurance of at least $500,000 for combined property damage and bodily injury per occurrence. Before doing HVACR work, the contractor must also post a $3,000 surety bond in favor of the State, renewed every 12 months. Ask for the insurance certificate before work starts. (Source)
How do I check an HVAC contractor’s license in New Jersey?
Use the Division of Consumer Affairs license verification site. Choose Person Search and the profession “HVACR” (license type “Master HVACR Contractor”), then search by name, license number or city. Board rules require the license number on the contractor’s vehicles, invoices and advertising, so compare that number with the lookup result. (Source)
