HVAC Contractor License in North Carolina: Requirements, Qualifier, Bond and Exams

Statewide.

G.S. Chapter 87, Article 2 requires a license before any person, firm or corporation engages in, or offers to engage in, the business of plumbing, heating, or fire sprinkler contracting, and the requirement comes from state statute rather than city or county rules.

The structure is contractor-centric: North Carolina has no journeyman-style HVAC worker license, not everyone in a licensed firm must be licensed, and licensed work may be performed by the firm's bona fide W-2 employees under a listed qualified licensee.

The individual credential, the Technician license, is not a contracting license — your business contracts on its own contractor license, with a qualifier behind it.

The State Board of Examiners of Plumbing, Heating, and Fire Sprinkler Contractors issues the licenses under G.S. Chapter 87, Article 2, and its heating licenses come in three groups: Heating Group 1 for wet or water-based comfort heating, Heating Group 2 for forced-air heating and cooling systems over 15 tons of cooling capacity, and Heating Group 3 for forced-air systems of 15 tons or less.

Groups 1 and 3 each split into Class I (any building) and Class II (single-family detached dwellings only), while the board's definitions list a single Heating Group 2 license.

By statute, systems installed in single-family residences fall under Heating Group 3 regardless of size.

Fuel piping privileges are already included in the Heating Group 1, 2 and 3 licenses, so these licenses add fuel gas piping without a separate examination.

Two adjacent credentials come from other boards: commercial, industrial, service and transport refrigeration is licensed by the separate NC State Board of Refrigeration Contractors in Classes I through IV — a licensing article that excludes comfort cooling — and the SP-PH license for limited electrical work incidental to plumbing and HVAC is issued by the NC State Board of Examiners of Electrical Contractors.

A company license is issued in the name of a corporation, partnership or trade name only when an officer, general partner or full-time employee empowered to act for it holds the license and exercises general supervision — that person is your qualifier.

The experience bar is 2 years (4,000 hours) of on-site full-time experience in the category — up to half (2,000 hours; 45 quarter or 30 semester hours) may be academic or technical training — and applicants must be at least 18.

One qualifier cannot carry several companies: a licensee may be listed on only one contractor license at a time.

Each business location must have a listed license holder in the required classification on duty — the lesser of 1,500 hours a year or all hours of licensed activity — with authority over contracts and general supervision.

Cross-category experience earns partial credit: an H3-I licensee can receive 50% credit on an H-2 application, and vice versa.

A technician who passed the technical exam can obtain the contractor license in the same category by passing only the business portion.

Applicants submit a nationwide criminal background report from Disahealthcare.com with the application, and processing currently averages six weeks.

Contractor candidates take a 4-hour technical exam plus a 1.5-hour Business and Law exam, both computer-based and administered by PSI Services LLC at testing centers in Asheville, Charlotte, Fayetteville, Greenville, Raleigh, Wilmington and Winston-Salem.

The Business and Law exam is waived for an applicant who holds a currently active contractor license with the board and passed its Business and Law exam after August 2003.

Both exams are open-book: candidates bring their own approved references, and heating and cooling candidates bring their own ductolator.

The heating references include ACCA Manual J, Manual D, Manual N, Manual Q and Manual CS, Modern Refrigeration & Air Conditioning, and the NC Mechanical, Fuel Gas, Energy Conservation and Residential Codes; the business and law references are the board's Laws & Rules book and Business & Project Management for Contractors.

As of June 1, 2026 the exams are still based on the 2018 NC codes, because the 2024 code's effective date is postponed until at earliest May 1, 2027.

Fail a portion: there is a 90-day wait before retesting, with a Re-Examination Application and a new fee, though a failed portion can be retaken within six months without retaking the portion passed.

This is the requirement our research could not confirm.

We found no surety bond or minimum insurance requirement for North Carolina plumbing and heating contractor licenses in G.S. 87 Article 2, the board's rules at 21 NCAC 50, or the board's applicant pages.

That is an absence in our reading rather than a board statement that none is required, so ask the board what applies to your license before you bid, and confirm insurance questions with your insurer.

The examination application fee is $150 per exam and is non-refundable; under the board's rules that is a $75 application fee plus a $75 exam fee.

After passing, you must submit the License Activation Form and fee within 45 days or you retest.

The annual license fee for plumbing, heating and fuel piping contractor licenses is $150, and a second or subsequent qualifier listed on the same firm license pays $75.

Every license the board issues expires December 31 each year and must be renewed annually — there is no grace period after expiration; a renewal received late, after January, carries a $25 late processing fee, and a license not renewed within three years of expiration requires re-examination.

No continuing education has been required for renewal since December 31, 2012; the requirement was replaced by Disciplinary Education imposed after complaints.

Military veterans may seek licensure without examination under G.S. 93B-15.1, paying a $30 application fee and the $150 annual license fee.

Once licensed, the firm's contractor license number and qualification must be displayed on firm contracts, proposals, permit applications and yellow-page advertising.

No. The board's applicant page states there are no license reciprocity agreements with any other state.

What it does offer is narrower: a technical-exam waiver agreement with South Carolina only — the board's exam application maps SC Residential HVAC to North Carolina Heating Group 3 Class II, and SC Commercial Mechanical AC to Heating Group 2 and Heating Group 3 Class I — and passing the North Carolina Business and Law exam is still required.

Separately, the board's applicant page also names the Neighbor State License Recognition Act for North Carolina residents already licensed in Georgia, South Carolina, Tennessee, Virginia or West Virginia; check the current details with the board before you rely on it.

The refrigeration board has no reciprocity with other states either.

Stop contracting, immediately.

If the firm's license holder leaves — or is ill, dies, or is otherwise gone — all contracting activity, including quoting, bidding, contracting, obtaining permits and performing work, including work in progress, must cease until another licensee is in place as the firm's qualifier; there is no grace period.

Both the firm and the departing licensee must notify the board within 30 days.

And since every business location must have a listed license holder on duty for the lesser of 1,500 hours a year or all hours of licensed activity, there is no licensed-work gap to work through: line up and list the next qualifier before your current one gives notice.

No. There is no dollar threshold: anyone who installs, alters or restores plumbing or heating systems for a valuable consideration is contracting and needs the license, and so does anyone installing in property built for sale or rent, even without payment.

The statute's carve-out is repair scope, not job value: minor repairs and replacements of parts that do not change the energy source, fuel type, or routing or sizing of venting or piping — parts including a compressor, coil, contactor, motor or capacitor — do not require the license.

Installing or replacing condensing units, air handlers, gas furnaces, package units, boilers or water heaters does.

The board runs a public license search covering plumbing, heating and fire sprinkler licenses at public.nclicensing.org — the same search a homeowner or general contractor can run on your firm.

Refrigeration licenses sit on the refrigeration board's own lookup.

Check a license number before you subcontract HVAC work, and keep your own listing current: the search is also a quick way to confirm the board lists your qualifier on the right license and classification.
