How Do You Get an HVAC License in North Carolina?

Yes.

North Carolina licenses HVAC work statewide: under G.S. Chapter 87, Article 2, a license must be obtained before any person, firm or corporation engages in the business of heating contracting.

The license belongs to the contracting firm through a listed qualified licensee — not everyone working in a licensed firm must hold one, because the firm's bona fide W-2 employees may perform licensed work under that licensee.

There is no dollar threshold: anyone who installs, alters or restores heating systems for a valuable consideration is contracting and needs the license, and so does anyone installing in property built for sale or rent.

Minor part-for-part repairs are the statutory exception: replacing a compressor, coil, contactor, motor or capacitor — where nothing changes in energy source, fuel type, or routing or sizing of venting or piping — requires no license, while installing or replacing condensing units, air handlers, gas furnaces, package units, boilers or water heaters does.

The board splits HVAC — it says heating — into three groups: Heating Group 1 for wet, water-based comfort heating, Heating Group 2 for forced-air heating/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 come in Class I (any building) and Class II (single-family detached dwellings only); Group 2 has no class split.

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

Each group can be held as a Contractor license (technical plus Business and Law exams) or a Technician license (technical exam only — a technician license is not a contracting license, and a technician must be a sub-licensee of a contractor to assist with supervision).

There is no journeyman or apprentice HVAC license in North Carolina, and fuel piping privileges are already included in the Heating Group 1, 2 and 3 licenses.

Technician applicants need on-site full-time experience: 18 months (3,000 hours) for Class I, 15 months (2,500 hours) for Class II.

Contractor applicants need 2 years (4,000 hours) in the category, of which up to half — 2,000 hours, or 45 quarter or 30 semester hours — may be academic or technical training; an H3-I licensee receives 50% experience credit on an H-2 application, and vice versa.

Applicants must be at least 18, and the Board may require you to establish that before the exam.

The application-and-examination fee is $150 per exam and is non-refundable.

Applications must include a nationwide criminal background report from Disahealthcare.com, and processing time is currently averaging six weeks.

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

The board's exams are computer-based, administered by PSI Services LLC at testing centers in Asheville, Charlotte, Fayetteville, Greenville, Raleigh, Wilmington and Winston-Salem.

Heating Technician exams (Group 1, 2 or 3) run 4.0 hours with no Business and Law exam; contractors add a 1.5-hour Business and Law exam, waived if you hold an active board contractor license and passed it after August 2003.

They are open-book: bring your own approved references (hard-bound, spiral or ring-bound originals; highlighting and permanently attached commercial tabs only) and, for heating/cooling, your ductolator.

Heating references include ACCA Manual J (8th Ed.), Manual D (3rd Ed.) and Modern Refrigeration & Air Conditioning; as of June 1, 2026 the exams remain on the 2018 North Carolina codes, the 2024 code's effective date postponed to the earliest possible May 1, 2027.

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

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

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

Every license the board issues expires December 31 each year and must be renewed annually; there is no grace period after expiration.

A heating technician license renews at $75 a year, whether or not it is listed under a contractor; the contractor license's annual fee is $150, or $75 for a second or subsequent qualifier listed on the same firm license.

A renewal received after January carries a $25 late processing fee.

A license not renewed within three years of expiration requires re-examination.

There is no mandatory continuing education: the requirement was eliminated on December 31, 2012, and was replaced by Disciplinary Education imposed after complaints.

No. The board states there are no license reciprocity agreements with any other state.

The one accommodation is a technical-exam waiver agreement with South Carolina, limited to specific contractor licenses: a SC Residential HVAC license maps to NC Heating Group 3 Class II, and SC Commercial Mechanical AC maps to Heating Group 2 and Heating Group 3 Class I — and the North Carolina Business and Law exam is still required.

Separately, the Neighbor State License Recognition Act is the route for NC residents already licensed in Georgia, South Carolina, Tennessee, Virginia or West Virginia.

The board's public lookup covers plumbing, heating and fire sprinkler licenses at public.nclicensing.org/Public/Search.

Refrigeration licenses sit with the separate refrigeration board, which keeps its own database at ncrefrigerationboard.arlsys.com/Public/Search.

Check a license by name or number before you hire a contractor, and before you take a job with a firm that says it is licensed.

Commercial, industrial, service and transport refrigeration is licensed by a different body: the NC State Board of Refrigeration Contractors, in four classes — Class I commercial, Class II industrial (ammonia), Class III refrigeration service and Class IV transport refrigeration.

That article excludes comfort cooling: selling, repairing and installing comfort cooling devices or systems falls under the plumbing/heating board's Heating licenses, not the refrigeration board.

Refrigeration exam applicants need at least 4,000 hours of experience under a licensed refrigeration contractor, registered PE or equivalent, with up to half from academic or technical training; the exam fee is $100 and the exam is given at the Board office in Garner.

Refrigeration licenses are issued to individuals only (a company name may be added), there is no reciprocity, and failing to renew two consecutive years requires re-examination.

Employees working under the supervision of a licensed refrigeration contractor are not themselves engaged in refrigeration contracting.

From July 1, 2026, the board's commercial and service exams include CO2 (R-744) questions.
