A New Jersey HVAC license is the Master HVACR contractor license, and it belongs to you as a person. A business, your own one-truck LLC included, can sell heating, cooling or refrigeration work only through a master who owns at least 1% of it and registers with the board as its bona fide representative within 30 days, and one master can do that for one company at a time. Before the first job the board wants a $3,000 surety bond, a $500,000 liability insurance certificate and the business's federal tax ID on file. Your license number goes on every truck, invoice and ad.

If your company is on the home improvement register with an HVAC name, the short version is harder: that registration doesn't cover HVAC work at all. Not a change-out, and not a tune-up either. Below is how the license and the business fit together, what the license covers (gas piping and the wire to the condenser included), where it stops, permits, a table for the jobs customers call about, what crossing the line costs, and a 30-day checklist you can print.

NJ Master HVACR license vs. your HVAC business: the bona fide representative

New Jersey licenses one kind of HVAC contractor, the master. The law says "a person shall not work as a Master HVACR contractor" unless licensed, and no "person, firm, partnership, corporation or other legal entity shall ... engage in the business of HVACR contracting or advertise in any manner as a Master HVACR contractor" unless authorized.¹ There's no separate license for the firm, and no company form on the board's forms page.² A business gets its standing through a master who acts as its bona fide representative: a Master HVACR contractor "who has not less than one percent ownership" of the corporation's stock, the partnership's capital or the firm.³

The 1% has a definition. The master "is entitled to one percent of any net profits from a business, owns one percent equity," and gets 1% of the net proceeds if the business is sold. In a corporation with more than one class of stock, the master's shares must be "the highest level stock with full voting rights."³ The board wrote the 1% test into its rules in January 2022.⁴ A company that earns more than 65% of its revenue outside HVACR, or a publicly traded one, can use its owner, a partner, an LLC manager or an executive officer instead.^{3, 5}

A New Jersey poster put the basic rule plainly: "you need to have a Master HVACR contractor's license to buy or start an HVAC business".⁶ A reply in the same thread added: "Have to give them minimum of 25% equity for it to be legal... just btw... There is no 'renting' a license."⁷ The second half is right. The 25% isn't in the law. The floor is 1% (New Jersey's plumbing rule is 10%, which may be where bigger numbers come from).

• Register within 30 days. Once you take on the role, you send the board the business's name and address, its officers if it's a corporation, the business's written consent that you're its agent for service of process, and its written acceptance of liability for penalties, consumer refunds and costs assessed against you.⁸ The board's form has you sign both statements and finish with an affidavit in front of a notary. It dates from 2015 and still asks you to tick owner, partner, manager or officer, so if you qualify through the 1%, say so.⁹
• One company. You "Serve as a bona fide representative for only one HVACR business," and you keep a place of business in New Jersey or name an agent here for service of process.¹⁰ I read this rule in LII's republication of the code; the official text sits on the state's LexisNexis site, which I couldn't open.
• What you sign up for. You supervise all HVACR work the business does, see that permits get pulled, and answer for "any and all violations" employees commit on work you were required to supervise. You also have to know the books well enough to tell the board about the company's "price-setting, billings, costs, subcontractors, overhead costs, and profits."¹⁰
• If the master leaves. The business can keep working for 60 days without a bona fide representative, as long as a master supervises all the work and the business, the departing master and the stand-in each tell the board within 10 days. After a death, illness or disability, the window is six months.⁸ The statute's six months also names "termination of employment,"¹¹ but the board's rule gives a company whose master withdraws 60 days, so plan on 60.
• It can't be lent. The pressure seal is used "exclusively by the master HVACR contractor," and letting someone else use it, or securing a permit for an unlicensed person, counts as "dishonesty, fraud, deception, misrepresentation, or false pretense."¹² Transferring an HVACR license to another person adds a civil penalty of up to $15,000, then $25,000.¹³

Being someone else's bona fide representative works the same way: you own at least 1% and register, or you don't do it. The board can act against you for violations by employees on work you were required to supervise, and anyone with a claim on a bond can go after you as well as the company.¹⁰ The company's signed acceptance of liability helps, but it's your license on the line.⁸ Because 1% is cheap to give, expect offers. When I pulled Google's top ten for "nj master hvac license" on November 3, 2026, two were Facebook posts about finding or being a New Jersey master for someone else's company. What the role pays and what to ask before you say yes is a separate article.

One date to watch: the board's rules (N.J.A.C. 13:32A: the 30-day registration, the one-company rule, supervision, vehicle lettering) expire February 4, 2027.^{4, 14} Rules lapse unless the agency readopts them, and it can keep them unchanged for seven more years by filing a notice at least 30 days before.¹⁵ I found no readoption proposal on the Division's proposals page on November 3, 2026.¹⁶ The statute (the license itself, the 1%, the bond and the insurance) doesn't expire.

NJ HVAC license requirements, in one paragraph

If you're reading this before the exam, here's the road. You must be 21 and show five years in the HVACR contracting business: at least four in an HVACR apprenticeship approved by the US Department of Labor (steamfitter, pipefitter and sheet metal programs count) and one as a journeyperson. A two-year HVACR program at an accredited trade school or college covers two of the four apprenticeship years. A bachelor's in HVACR plus one year installing and servicing systems, or a related bachelor's plus three years, also qualifies.¹⁷ Your employer has to sponsor the apprenticeship, and the board's FAQ says it doesn't move with you to a new employer.⁵ The exam has two written parts (HVACR practice, and New Jersey law and rules) and you need 70 on each; fail and you wait six months. It runs at least four times a year.¹⁷ The application fee is $100, and the initial license fee is $160 in the first year of the two-year period or $80 in the second, plus $25 for the pressure seal.¹⁸ The board approves applications at its monthly meeting, and the license comes 15 to 20 days after the fee is processed. The grandfather route closed on September 3, 2014.⁵ Licensed in another state? The board may license you without the exam if that state's standards are comparable and it gives New Jersey masters the same deal.¹⁷ The rest of this page is what comes after.

What your NJ HVAC license covers

HVACR, in the statute, is a long list. It starts with handling refrigerants "in stationary sources" and runs through boilers, hydronic heating, furnaces and space heaters, warm air heating, refrigeration and evaporative cooling, ventilation and exhaust, air handlers, coils, compressors, chillers, condensers, humidifiers, filters, "humidity and thermostatic controls," and "natural or manufactured gas piping on the load side of a meter."³ Contracting means doing any of it "for a fixed price, fee, commission, or gain of whatever nature," and that includes "maintenance, service, repair."³ I found no residential or commercial class and no dollar limit in the law or the board's rules. The parts new owners ask about:

• Heating, any fuel. Furnaces, boilers and space heaters "utilizing electric, fossil fuel, wood pellets, or solar energy," plus oil, gas and coal burners and their controls.¹⁹ Central air, heat pumps and ductless mini-splits sit under the cooling, refrigerant and air handling items.
• Boilers and hydronic heat. Boilers, hydronic piping, expansion tanks, pumps, radiators and fan coil units are on the list.³ You don't need a plumber for them, though master plumbers may do boilers and hydronic work here too.²⁰
• Propane. The board's rules add "the provision of propane services," meaning leak testing and installing or servicing propane appliances, furnaces and containers.¹⁹ Licensed LP gas marketers are outside the act altogether.²¹
• Ductwork and ventilation. Plenums, fans, blowers and the "related air distribution systems," plus the testing and balancing of air and hydronic systems.¹⁹
• Refrigeration. Walk-ins, reach-ins and ice machines come under "refrigeration piping," compressors, evaporators and condensers.¹⁹ The license has no tonnage cap. The wiring rule below does.
• Water to your equipment. You may run "supply water piping to equipment being served from an existing dedicated source connected downstream from an approved backflow preventer," and install a replacement non-testable backflow device downstream from an existing valve.¹⁹ For ice machines and humidifiers the board says you may connect the piping if the unit has a backflow connector; if it has no backflow preventer, you may not install the piping.⁵
• Condensate. "Condensate piping not discharged into a sanitary sewer," with disposal following the construction code.¹⁹
• Geothermal. The horizontal connections between the wells and the heat pump. Drilling, grouting and anything placed in the well need their own licensing under the Department of Environmental Protection.¹⁹
• In-duct smoke detectors. You may install them, wire them to the equipment or a remote station, and service them.¹⁹
• Not design. The definition stops at design work "within the practice of professional engineering."³

Gas piping in NJ: it's in your license

Gas piping is written into the HVACR definition itself: "natural or manufactured gas piping on the load side of a meter."³ That's the line from the meter to the furnace, boiler, rooftop unit or unit heater, and you don't need a master plumber for it. Master plumbers may run gas piping too, under a carve-out in the same law.²⁰ The definition doesn't tie the gas line to heating equipment, and the board's rules let electrical contractors pipe gas to generators only as a named exception, after two hours of training.²² So, as I read it, a gas line to a standby generator or a range is inside your license as well. Three limits:

• Fireplaces and fire features. Gas fireplaces, inserts, log sets, outdoor fire pits and patio heaters are "hearth professional work," and the law says no one may run gas piping for them "unless licensed by the board as a master hearth specialist."²³ That law doesn't stop other licensees working within their own scope, but a decorative fireplace isn't on the HVACR list, so ask the board before you quote one.
• The utility. New gas service, or more gas for a generator or tankless water heater, goes through the utility first. PSE&G says customers "must apply to PSE&G to add or increase service for gas generators or tankless hot water heaters," and generator projects can take up to six weeks. New or upgraded service also needs "a mandatory local inspection to receive your Certificate of Approval (or cut-in card)" before the utility's service date.²⁴ A swap on an existing gas line doesn't involve the utility; outside PSE&G's area, ask your gas utility how it takes contractor requests before you promise a date.
• The permit. New or altered gas piping is never ordinary maintenance, so it needs a permit.²⁵ The fuel gas subcode is the 2024 International Fuel Gas Code.²⁶

The electrical line to the condenser

This is where the license is narrow. A Master HVACR contractor "shall not perform any electrical work which has a potential of greater than 30 volts" on HVACR equipment, except on replacements and where the electrical law exempts the work.²⁰ What that leaves you:

• Thermostat and control wiring: yours. Standard thermostat wiring runs at 24 volts, under the line, and thermostatic controls are on the HVACR list.¹⁹
• Reconnecting a replacement: yours, within limits. You may connect the wiring "from an equipment service disconnect box of adequate size" that was "previously dedicated to that equipment," if each piece of equipment is 25 tons or less, the system is 240 volts or less, and the connection follows the construction code.¹⁹
• The disconnect: not yours. The board's answer: "a licensed master HVACR contractor may not replace a disconnect box or disconnect switch." A surge protector on the load side of the disconnect is fine; on the line side it "requires a licensed electrician."⁵
• Service calls: the electrical law exempts "the testing, servicing or repairing of electrical equipment or apparatus," and the HVACR law points to those exemptions, so a capacitor, contactor or motor on a service call is fine.^{27, 20}
• Gas and oil burners: the electrical law also exempts "the maintaining, installing or connecting of automatic oil, gas or coal burning equipment" to "a supply of adequate size at the load side of the distribution board."²⁷ As I read it, that lets you connect a gas furnace or boiler to an existing, adequate circuit.
• Anything new on the line side: a new circuit, a new or bigger breaker, a new disconnect or a new whip from the panel is electrical contractor work.^{20, 27} On most ductless mini-splits, the cable between the outdoor unit and the heads carries 208 to 240 volts. As I read the 30-volt rule, that's the electrician's on a new install. Ask the board in writing before you land it yourself.

It cuts both ways: electrical contractors may maintain and repair "the electrical sections of any equipment used for heating, ventilating, air conditioning or refrigeration," and install electric resistance heat and small exhaust fans.²⁰ My NJ electrical contractor license article covers their side.

HVAC-named firms on the home improvement register: what you may and may not do

Four of the six New Jersey HVAC rows on my list this month are home improvement registrations with an HVAC name. That's the Division of Consumer Affairs' register for home improvement businesses, and it stops where HVAC starts: "home improvement" "does not apply to any work required to be performed by a licensed master heating, ventilating, air conditioning, and refrigeration contractor."²⁸ The registration lets you sell remodeling, windows or insulation. It gives you nothing on the equipment.

Without a master, the law leaves very little HVAC work open. "HVACR contracting" is any of the listed work "for a fixed price, fee, commission, or gain of whatever nature," including maintenance and service, and "advertising to undertake" it counts.³ No firm may "engage in the business of HVACR contracting or advertise in any manner as a Master HVACR contractor" unless it has a licensed bona fide representative, and knowingly doing it is a crime of the fourth degree.^{1, 29} I found no carve-out for tune-ups, filter changes or duct cleaning; the definition names "filters," "air cleaners" and maintenance.³ The exemptions go to other licensed trades within their scope, single-family homeowners on their own homes, utilities, licensed LP gas marketers, and in-house maintenance staff who don't contract with the public.^{22, 21} As I read it, that leaves three clean routes:

• Bring in a master who owns at least 1% and registers as your bona fide representative within 30 days. Everything in this article then applies to the HVAC side of the business, and you keep the home improvement registration for the rest.^{3, 8}
• Refer HVAC jobs to a licensed HVACR company that signs with the customer directly. Selling the job yourself and subbing it out still reads like "undertaking" HVACR contracting, and the board's subcontracting rule is written for HVACR businesses with a registered representative on both sides.^{3, 10}
• Keep heating, cooling and HVAC words off the name, the trucks, the website and the listings until one of those two is in place.

The registration's own rules still apply to the rest of your work: liability insurance of $500,000 per occurrence, workers' compensation, and "HIC reg. #" with your number on both sides of your vehicles.²⁸ My NJ home improvement contractor license article covers it.

Federal rules every NJ HVAC business meets

EPA Section 608. EPA's rules "require that technicians who maintain, service, repair, or dispose of equipment that could release refrigerants into the atmosphere must be certified." There are four types: Type I for small appliances, Type II for high-pressure systems (where residential split systems sit), Type III for low-pressure, and Universal. The cards don't expire. To buy refrigerant, "any person servicing, installing or disposing of stationary appliances ... must be a section 608 certified technician," and the seller has to check. An office manager can still buy on the company account if the seller has a copy of the tech's card and a list of who may buy. Apprentices are exempt only while "closely and continually supervised by a certified technician."³⁰ New Jersey adds one line of its own: a single-family homeowner may work on their own home's system, but "any HVACR work involving" CFCs or HCFCs (R-22 is an HCFC) is for a licensed master only.²¹

A2L refrigerants (R-454B, R-32). New Jersey switched its mechanical subcode to the International Mechanical Code 2024 on August 17, 2026, and kept its own refrigerant rule: "Only refrigerants listed by the US Environmental Protection Agency (EPA), pursuant to the Significant New Alternatives Program (SNAP) ... shall be permitted."²⁶ EPA's SNAP list for residential and light commercial air conditioning and heat pumps has R-454B (an A2L, global warming potential 470) as "Acceptable with Use Conditions," and R-32 (an A2L, 675) on it too.³¹ For six months after a code change, a complete permit application can still be reviewed under the old edition, so until about February 17, 2027 you may meet both at the permit counter.³² EPA's rule of May 26, 2026 lets residential and light commercial AC and heat pump equipment made or imported before January 1, 2025 "continue to be installed," so older R-410A stock isn't stranded.³¹ If your first A2L job is coming up, you're in good company: "Will be my first time installing these. I was always a service tech but now I have a company and have to up my install game."³³ Follow the maker's installation manual to the letter and ask your town's mechanical inspector what they'll look at.

EPA lead-safe rules (RRP). New Jersey isn't on EPA's list of states that run their own program, so EPA runs it here. Anyone "paid to perform work that disturbs painted surfaces in homes, childcare facilities and preschools built before 1978" has to be certified, with employees trained in lead-safe work. For you that means cutting a new register opening, a chase or a vent through painted walls. The minor repair exception stops at 6 square feet of painted surface per room inside or 20 square feet outside, and jobs in the same room within 30 days count together.³⁴

Who can work under you: journeypersons, apprentices and helpers

HVACR work you agree to do, and don't sub out, "shall be performed only by the master HVACR contractor or those employees ... whose remuneration is reported on a Form W-2."³⁵ A 1099 helper on the equipment doesn't fit. If you hire, budget from the going wage: the Bureau of Labor Statistics' 2025 median for HVAC mechanics in New Jersey was $35.79 an hour, against $29.33 nationally.³⁶ New Jersey licenses masters only. The law defines journeypersons and apprentices, but I found no license or registration for either in the board's statute or rules.³ I found no apprentice ratio either. Supervision goes by experience:¹⁰

• A master on your payroll: a report at the start of the job and a final report at the end.
• Two years' experience or more: daily contact in person, by phone or in writing, recorded, and you (or a master you employ) inspect permitted work when it's done.
• Preventive maintenance by someone with at least a year: daily contact, recorded.
• Everyone else under two years: "constant on-site supervision" by a master or a journeyperson with at least five years' experience, the whole time HVACR work is going on.

If you sub HVACR work on a consumer job, it goes only to a master sole proprietor or a business with a registered bona fide representative. Before work starts you tell the customer the sub's name, address and phone, its representative's name and license number, that they may cancel because of the subcontract, and that you both stay liable. The sub sends you copies of its permit applications within five business days.¹⁰ Sub out more than a third of your HVACR work in a year and every ad must say: "A substantial part of the HVACR work which we undertake may be subcontracted to independent licensed HVACR contractors."³⁷ Workers' compensation goes in before the first employee starts. Without it you face a disorderly persons offense, a stop-work order and penalties of up to $5,000 for every 10 days uninsured, and you're liable for an uninsured sub's injured worker.³⁸

Where your NJ HVAC license stops

• Domestic water. The HVACR definition leaves out equipment "utilized solely for the purpose of heating potable water."³ The board says you may replace a combination tankless water heater and hydronic unit "but may not connect or disconnect the domestic (potable) water."⁵ Water heaters and new backflow preventers on the water supply are master plumber work.³⁹
• Condensate into the house drain. Plumbing includes "refrigeration and air conditioning drains," and your scope covers condensate piping "not discharged into a sanitary sewer."^{39, 19} As I read that, tying a condensate line into the drain system is the plumber's. My NJ plumbing license article covers what a master plumber does.
• New circuits, disconnects and panels. Electrical contractor, as above.²⁰
• Gas fireplaces and fire features. Master hearth specialist, unless the board tells you otherwise.²³
• Well drilling and engineering design, as above.^{19, 3}
• The rest of the remodel. The home improvement registration law exempts a state-licensed trade "acting within the scope of practice."²⁸ Carpentry, drywall or insulation sold as work of its own isn't HVACR, and needs the registration.

One set of rules follows you onto every house anyway. The Home Improvement Practices rules apply to every seller "whether or not they are exempt" from registration, and their definition of home improvement names "central heating and air conditioning equipment." Contracts over $500 go in writing, work waits until required permits are issued, and the customer gets copies of inspection certificates before the final payment is due.⁴⁰ The NJ home improvement contract template covers the written part.

NJ HVAC permits: who pulls them, who inspects

New Jersey has one statewide construction code, the Uniform Construction Code, enforced by each town's construction office. Since August 17, 2026 the mechanical subcode has been the International Mechanical Code 2024, and the fuel gas subcode the International Fuel Gas Code 2024.²⁶ In existing one- and two-family houses, a mechanical inspector handles heating, cooling, refrigeration, ventilation and gas piping. Where a town has none, the plumbing subcode official or a plumbing inspector does it.²⁶

The permit is yours to pull. You "shall impress [your] pressure seal upon all applications for HVACR permits," and the code wants your name, license number, seal and signature on the subcode application.^{41, 42} Since May 18, 2026 a digital signature and seal counts the same as the pressure seal, as long as it's unique to you, verifiable, and kept on a private digital key under your control.¹⁴ As bona fide representative you can send an employee with a letter carrying your seal, good for up to 60 days, but "the permit shall be signed by a master HVACR contractor."¹⁰ Bring your wallet ID card, since the permit office can ask for it.³⁵

The code sorts HVAC jobs into three bins:

• No permit (ordinary maintenance). Motors, pumps and fans of the same capacity; heating supply and return piping repairs "which does not require rearrangement of the piping system"; "repair and replacement of duct work"; "repair of air conditioning equipment and systems"; "repair or replacement of control devices."²⁵ No permit doesn't mean no license.³
• Start on notice, file within five business days (minor work). "The replacement of existing low-pressure boilers, warm air furnaces, air conditioning units, and air conditioning condensing units with new appliances of like capacity," condensate drains in existing buildings, and, in one- and two-family homes, the electrical work incidental to an AC install. The town inspects within three business days of your request.⁴³
• Permit before you start: everything else. That includes new gas piping, a system that isn't like capacity, and equipment where there was none.^{25, 44} In an emergency you can start and apply "not later than 72 hours thereafter."⁴⁴

The like-for-like change-out is the easy bin. Call it in, do the job, file within five business days, and hand the customer the inspection certificate before you ask for the last payment.^{43, 40} A bigger system, or a switch from furnace and AC to a heat pump, isn't obviously "like capacity," so ask the town before you treat it as minor work.

The homeowner exemption covers the homeowner's own hands, not yours. The law exempts a single-family homeowner "who personally occupies his own dwelling and who solely performs HVACR work on his own dwelling, upon receipt of all required permits."²¹ A customer who pulls a homeowner permit and then hires you has a permit that doesn't fit the job.⁴²

Local licenses: towns can inspect, not license

The law says "a municipality, local board of health or any other agency shall not issue or renew any Master HVACR contractor's license," and none may make you "obtain any additional license, apply for or take any examination, or pay any licensing fee." Towns keep the power to inspect and to enforce standards.⁴⁵ No town may ask for a bond like the state's either.⁴¹ Your license works the same in Newark as in Cape May. Two big cities run contractor licenses worth knowing about:

• Newark licenses general, demolition, moving, and roofing and siding contractors. It has no HVAC class.⁴⁶
• Jersey City says "A JC Contractor license is required for all non-state licensed contractors and for all work done on a commercial property."⁴⁷ The state law reads against that for licensed masters, so before a commercial job there, ask the construction code office in writing.

Can I take this job? A table for NJ HVAC contractors

Two questions decide every row. Who is allowed to do the work is the licensing law. Whether it needs a permit is the construction code. "Yes" means your Master HVACR license, with a registered bona fide representative behind the business, covers it. "Sub it out" means another licensed trade does that part, on its own permit.

What happens if you cross the line in NJ

• Working as a master without a license, or contracting without a master behind the business. Knowingly doing either is a crime of the fourth degree, on top of civil penalties.¹ That carries up to 18 months and a fine of up to $10,000.⁴⁸ The civil penalties run up to $10,000 for a first violation and $20,000 for each one after, with each act counted separately, plus the State's investigation and legal costs.¹³
• Lending the license, the seal or the ID card. Up to $15,000, then $25,000, for transferring a license.¹³ An unlicensed person who uses your seal, or gets a permit through you, can be refused a license "at any point in the future," and the same goes for your ID card.^{12, 35}
• Skipping the registration or the permits. Both are duties under the board's rules, and every violation of a board rule carries the civil penalties above.^{8, 10, 13}
• Letting the license lapse. Renew by June 30, 2028. For 30 days after that, renewal plus the $50 late fee keeps the license valid. Then it's "suspended without a hearing," and working on it is unlicensed practice "even if no notice of suspension has been provided."^{49, 18} The company you stand behind can't operate under your license either.¹¹
• Letting the insurance lapse. A replacement certificate has to reach the board "before the former policy is no longer effective," and you can't keep the pressure seal without it.⁴¹
• The bond. Anyone "injured, aggrieved, or damaged" by your failure to follow the HVACR law or rules can claim on your $3,000 bond, and you top it back up to $3,000 after a claim.⁵⁰
• The price. A price "so high as to be manifestly unconscionable or overreaching" is occupational misconduct under the board's rules.³⁵
• No workers' comp. A disorderly persons offense, a fourth-degree crime if knowing, a stop-work order, and penalties of up to $5,000 for every 10 days uninsured.³⁸

Can you still collect?

I found no New Jersey statute that voids an unlicensed HVAC contractor's contract, and no published New Jersey decision on one suing for payment. The risk sits elsewhere. On a house, the Home Improvement Practices rules say no work until required permits are issued, and only a licensed master can seal an HVACR permit application.^{40, 41} Breaking those rules is a Consumer Fraud Act violation. A customer with "any ascertainable loss" can sue or "assert a counterclaim," and the court awards "threefold the damages sustained" plus attorneys' fees.⁵¹ Licensed tradesmen have lost money on the paperwork side too: in a published 1997 case, an electrician's oral agreement for extra work was "unenforceable under the Act and the regulations," so he was "limited to quantum meruit," meaning whatever he could prove the work was worth.⁵²

Insurance: no New Jersey rule I found voids an HVAC contractor's liability policy for work outside the license. Read your policy's exclusions before you take anything off the "sub it out" rows above.

Your first 30 days: the NJ HVAC license checklist

This is the whole list. The printable version has the same items with blanks for your license and bond numbers, policy numbers, your bona fide representative registration, EPA 608 card numbers and your renewal date: make your own copy in Google Docs, download the Word version (.docx), or download the PDF. Pick a format, enter your email and I'll send the links.

The business

• ☐ Entity. Form the LLC or corporation with the state, or, as a sole proprietor, file the trade name with the county clerk. The bona fide representative registration names the business, its address and, for a corporation, its officers.⁸
• ☐ Federal tax ID (EIN). The board wants the HVACR business's federal tax ID number when you license and when you act as a bona fide representative.^{12, 41}
• ☐ State tax registration (NJ-REG). "All businesses must register for state taxes" with the Division of Revenue and Enterprise Services.⁵³
• ☐ Sales tax. Repairs and maintenance are taxable: 6.625% on the labor, with only materials stated separately at your cost left out. A "New heating system" or "New central air conditioner" is an exempt capital improvement once the owner gives you a Form ST-8, which you keep.⁵⁴ Know which kind each job is before you quote it.

The board: license, bond, insurance, bona fide representative

• ☐ $3,000 surety bond in favor of the State of New Jersey, from a surety authorized in the state, filed before any HVACR work. It runs 12 months and renews, and the license renewal needs it. If you're also a master plumber, the plumbing board's $3,000 bond counts.^{41, 12}
• ☐ General liability, $500,000 "for the combined property damage and bodily injury to or death of one or more persons in any one accident or occurrence," certificate filed with the board.⁴¹ The board says that applies "any time" you provide HVACR contracting to the public, not only as a representative.¹⁴
• ☐ License fee and pressure seal. $160 if paid between July 1, 2026 and June 30, 2027 ($80 in the second year of the period), plus $25 for the seal. Only you use the seal; a digital seal is allowed if it meets the board's rule.^{18, 12, 14}

Where Deepsel fits

Deepsel is the field service software I build, and for this topic it handles the paperwork side. Your shop's name and address print on every online quote and invoice. Your shop-wide quote terms are copied onto every new quote and your invoice footer onto every invoice, so the master's name, "Master HVACR contractor Lic. #" with the number and your New Jersey street address can live there and reach the customer every time. Customers approve and sign quotes on screen. Each price book item has a taxable switch and each quote and job has its own tax rate, so a taxable repair and an ST-8 system replacement can sit side by side. Equipment records keep the type, brand, model, serial, year, filter size, tonnage, refrigerant, location and a nameplate photo, so the condenser you set is on file for the next call. It's free up to 30 estimates and 30 invoices a month, with scheduling and dispatch, quotes, invoicing, card payments, and customer and equipment records; Pro is $29 a month with unlimited estimates and invoices (see pricing). Deepsel doesn't know New Jersey law. It has no permit, inspection or license-renewal tracking, no field for bond, insurance or EPA 608 card dates, and it won't stop you quoting a gas fireplace.

Frequently asked questions

How do you get an HVAC license in NJ?

New Jersey's HVAC license is the Master HVACR contractor license from the State Board of Examiners of Heating, Ventilating, Air Conditioning and Refrigeration Contractors. You need to be 21 with five years in the trade: four in a US Department of Labor approved apprenticeship (a two-year accredited HVACR program covers two of them) and one as a journeyperson, or an HVACR degree plus one year, or a related degree plus three. Then you pass a two-part written exam with 70 on each part, file a $3,000 surety bond and a $500,000 liability certificate, and pay the license fee.

How long does it take to get an HVAC license in New Jersey?

Five years in the trade before you can apply, unless a degree shortens it. After that, the board reviews applications at its monthly meeting, you pass the exam (given at least four times a year, with a six-month wait after a fail), and the license arrives 15 to 20 days after your license fee is processed.

How much does an NJ HVAC license cost?

$100 to apply, then $160 for the license if paid between July 1, 2026 and June 30, 2027 ($80 in the second year of the two-year period), $25 for the pressure seal and $160 to renew every two years. Add the premium on the $3,000 bond and the $500,000 liability policy.

What is a bona fide representative for an NJ HVAC company?

The Master HVACR contractor a business operates through. The master owns at least 1% (of the profits, the equity and the sale proceeds), registers with the board within 30 days, supervises the HVACR work and permits, and stands behind one HVACR business only. Companies earning over 65% of their revenue outside HVACR, and public companies, can use an owner, partner, LLC manager or executive officer instead.

Can I do HVAC work in NJ without a license?

Not for pay. HVACR contracting includes maintenance, service and repair done for any fee, and advertising it counts too. A home improvement registration doesn't help, because its rules leave out work a licensed master HVACR contractor has to do. The exemptions cover other licensed trades within their scope, homeowners on their own single-family home with permits, utilities, licensed LP gas marketers and in-house maintenance staff.

Does an NJ HVAC contractor need home improvement registration?

Not for HVAC work, which the registration law and rules exempt. If you sell remodeling or other work as a job of its own, register for that part. The Home Improvement Practices rules (written contracts over $500, no work before permits) apply to your house jobs either way.

Can an HVAC contractor run a gas line in NJ?

Yes. Gas piping on the load side of the meter is part of the HVACR definition, so you don't need a master plumber for the line to a furnace, boiler or rooftop unit. Gas piping for fireplaces, log sets and outdoor fire features is master hearth specialist work, so ask the board before you take one.

Can an HVAC contractor wire an AC unit in NJ?

Partly. You may not do electrical work over 30 volts, except reconnecting replacement equipment of 25 tons or less at 240 volts or less to the disconnect that already served it. Thermostat and control wiring is yours. A new circuit, a new or replaced disconnect, or a line-side surge protector needs an electrical contractor.

When does an NJ HVAC license expire?

Licenses run from July 1 of an even-numbered year to June 30 two years later, so one issued now renews by June 30, 2028. You get 30 days' grace with a $50 late fee, then suspension without a hearing. No continuing education is due at your first renewal; after that, five credits every two years.

How do I look up an NJ HVAC license?

Use the state's license verification site at newjersey.mylicense.com/verification, or call the board at (973) 504-6250. Check your own record once the license and your bona fide representative registration go through, because customers, supply houses and general contractors will.

Does New Jersey have HVAC license reciprocity?

Case by case. The board may license a master from another state without the exam if that state's standards are comparable and it licenses New Jersey masters the same way. Its FAQ links a list of states it has already reviewed.

How much do HVAC technicians make in NJ?

The Bureau of Labor Statistics' 2025 median for New Jersey was $35.79 an hour, about $74,450 a year, against $29.33 an hour nationally. That's employee pay, so treat it as a floor when you set your own rate.
