Requirements at a glance

Who must be licensed: A license must be obtained before any person, firm, or corporation engages in, or offers to engage in, the business of plumbing, heating, or fire sprinkler contracting (G.S. 87-21(b)(3)). The credential is a CONTRACTOR license (by heating group and fuel piping), not an individual technician card. G.S. 87-21(c) applies the Article to work that "includes the installation or replacement of condensing units, air handlers, gas furnaces, package units, boilers, water heaters, heat exchangers," but exempts minor repairs and minor replacements (see below).
Minor repairs and replacements exemption: The Article does not apply to "those who make minor repairs or minor replacements to an already installed system of plumbing, heating or air conditioning" (G.S. 87-21(c)). The statute defines the term: "Minor repairs or minor replacements within the meaning of this subsection shall include the replacement of parts in an installed system which do not require any change in energy source, fuel type, or routing or sizing of venting or piping. Parts shall include a compressor, coil, contactor, motor, or capacitor." The exemption is defined by scope, not by price — Chapter 87, Article 2 sets no dollar threshold. Installing or replacing condensing units, air handlers, gas furnaces, package units, boilers, water heaters, or heat exchangers remains licensed work under the same subsection.
Employee exception: "An employee in the course of his work as a bona fide employee of a licensee (the statute, G.S. 87-25, sets no W-2 condition; the Board's own FAQ glosses this as "bonafide W2 employees", which is narrower -- a worker paid on a 1099 should not assume the employee exemption covers them) of the Board shall not be construed to have engaged in the business of plumbing, heating, or fire sprinkler contracting" (G.S. 87-25), so a licensed firm's employees are not required to hold their own license; the Board's FAQ likewise answers "No" to whether all persons in a firm must hold a license. The separate Heating Technician license is a distinct, non-mandatory individual credential.
Qualified individual on active duty: At each business location, branch, or facility from which licensed work is solicited or proposed, contracts are negotiated, requests are received or dispatched, or the work is carried out, there must be on duty "the lesser of 1500 hours annually, or all hours during which the activities described herein are carried out, at least one individual who holds contractor license in the classification required for the work," whose license is listed in the firm's name at that location and who has authority over contracts and general supervision of the work (21 NCAC 50 .0404(a)). Evidence of compliance is a condition of license renewal or retention.
Contractor experience: 2 years (4,000 hours) on-site full-time experience in the heating category sought; up to one-half (2,000 hours) may be academic or technical training directly related to the field.
Business and Law exam: Contractor applicants must also pass the Board's Business and Law exam (1.5 hours). It is waived only for an applicant who already holds an active Board contractor license and passed the Business and Law exam after August 2003.
Criminal background check: A criminal history report from the Board's approved provider must be submitted with the application; a report older than six months must be updated before re-examination.
Heating group scopes: Heating Group 1 covers "wet"/water-based comfort heating systems; Heating Group 2 covers forced-air heating/cooling systems with a mechanical refrigeration capacity in excess of 15 tons; Heating Group 3 covers forced-air heating/cooling systems of 15 tons or less. The tonnage split does not decide houses: "Systems installed in single-family residences are included under heating group number three, regardless of size" (G.S. 87-21(a)(3)) — a system over 15 tons in a single-family residence is Heating Group 3 work, not Heating Group 2. Class II variants (H1-II, H3-II) are limited to single-family detached dwellings. The Board's contractor License Definitions sheet states the tonnage split without the residential carve-out; that sheet describes itself as "a general outline" that "may not be detailed or inclusive of all activities," and the statute controls.
45-day license activation deadline: A passing applicant must submit the completed License Activation Form and the license fee within 45 days of passing the exam. The Board's form states the deadline on its face: "This form is due within 45 days of passing the exam or you must re-test."
Reciprocity: No general license reciprocity with any state. A technical exam-waiver agreement exists with South Carolina (NC business-law exam still required), and the Neighbor State License Recognition Act may allow equivalent licensure for NC residents licensed in GA, SC, TN, VA, or WV.

Legal basis

North Carolina State Board of Examiners of Plumbing, Heating and Fire Sprinkler Contractors administers HVAC contractor licensing in North Carolina. Every figure below is verified against the board’s own official pages and dated. Who must personally hold a credential — the contractor, the business, or the individual worker — is set out under Requirements.

What it’s called

In North Carolina the state credential is an HVAC contractor license, not an individual technician license. The State Board of Examiners of Plumbing, Heating and Fire Sprinkler Contractors licenses the CONTRACTOR (the business and its qualified individual), not the technicians it employs. A search for a “North Carolina HVAC license” maps to that contractor license; a technician working under a licensed contractor needs no separate state license. Separately, the federal EPA Section 608 certification (to handle refrigerants) is a nationwide requirement, not a state HVAC license. “HVAC license,” “AC license” and “HVAC certification” are common informal names for the state contractor credential.

Who does NOT need this license — exemptions

North Carolina’s exemptions all carve people out of the heating CONTRACTOR license (Heating Group 1/2/3, G.S. ch. 87, art. 2) — the separate Heating Technician license is voluntary, so an exemption from the Article is an exemption from the only mandatory credential. Beyond the minor-repairs/minor-replacements exemption in G.S. 87-21(c) and the bona fide employee exception in G.S. 87-25 (both already covered on this page), the Article contains: (1) NO CONSIDERATION, NO CONTRACTING — the licensing trigger in G.S. 87-21(a)(5) reaches only work done ‘for a valuable consideration.’ The Article contains no express homeowner exemption section; a homeowner doing unpaid work on their own home falls outside the definition because no consideration changes hands — but the same subsection closes the flip-and-rent loophole: a person who installs a plumbing, heating, or fire sprinkler system ‘on property which at the time of installation was intended for sale or to be used primarily for rental is deemed to be engaged in the business of plumbing, heating, or fire sprinkler contracting without regard to receipt of consideration.’ (2) PROFESSIONAL ENGINEERS — the same definition provides that ’nothing herein shall be deemed to restrict the practice of qualified registered professional engineers’ (G.S. 87-21(a)(5)). (3) POWER PLANTS (G.S. 87-21(c2)): the Article does not apply to electric generating facilities subject to G.S. 62-110.1 or providing FERC-regulated wholesale power — an industrial carve-out for generation facilities. (4) RETAIL SELLERS OF RESIDENTIAL HVAC SYSTEMS (G.S. 87-21(j)) — the ‘big-box store’ exemption: a person primarily engaged in retail sale of goods and services may contract for, or arrange financing for, the sale and installation of a single-family residential heating or cooling system without a heating license, but only if ALL of five conditions are met: the system’s specifications and design are reviewed and approved by a licensee (an employee of the retailer or the installing contractor) before any contract is presented or signed; the installer is licensed under the Article; the contract is signed by the buyer, the retailer, and the licensed contractor and carries the contractor’s name, license number, and telephone number plus the license number of the design approver; installation complies with building codes, manufacturer’s instructions, and permit/inspection requirements; and the retailer warrants the installation for at least one year. A parallel exemption in G.S. 87-21(i) covers retailers of water heaters for one- and two-family dwellings who contract with a licensee to install. Neither retail exemption extends to fire sprinkler systems (G.S. 87-21(k)). (5) MANUFACTURED-HOME DRAIN LINES (G.S. 87-21(c1)): on-site assembly of a factory-designed drain line system for a manufactured home by a licensed manufactured-home retailer or set-up contractor (or their full-time employee), with local inspection and State Plumbing Code compliance. (6) INSPECTORS AND RATERS (G.S. 87-21(l)): licensed home inspectors, certified Code-enforcement officials, and RESNET-certified home energy raters, to the extent they do not claim to be or act as a plumbing or heating contractor. (7) EMPLOYEES (G.S. 87-25): ‘An employee in the course of his work as a bona fide employee of a licensee of the Board shall not be construed to have engaged in the business of plumbing, heating, or fire sprinkler contracting’ — the carve-out that lets an HVAC technician employed by a licensed heating contractor work with no individual license (the Heating Technician credential remains optional). Note what is NOT exempt: G.S. 87-21(c) keeps the installation or replacement of condensing units, air handlers, gas furnaces, package units, boilers, water heaters, and heat exchangers inside licensed territory, and the Article sets no dollar threshold — the minor-work exemption is defined by scope (parts replacement with no change in energy source, fuel type, or venting/piping routing or sizing), not price.

Fees

Examination: $150 per exam, non-refundable. License activation (the first annual license fee): $150 per contractor classification, $75 per technician classification — $150 for a technician who is the qualifier for a State or local government employer. Annual license fee: $150 for a plumbing, heating, or fuel piping contractor license (21 NCAC 50 .1102(a)), reduced to $75 for a contractor “whose qualifications are listed as the second or subsequent individual on the license of a corporation, partnership, or business with a trade name” (21 NCAC 50 .1102(d)). Technician annual license fee: $75 — but two official Board documents state OPPOSITE conditions for that rate. 21 NCAC 50 .1102(j) sets $75 for “Plumbing, Heating or Fuel Piping Technician licensees listed under a licensed Plumbing, Heating or Fuel Piping Contractor,” while the Board’s 2026 renewal invoice charges $75 for “a Plumbing, Heating/A/C or FP tech license NOT listed under a contractor.” The $75 figure is common to both; the condition is unresolved, so confirm your rate with the Board. An applicant who obtains a license by passing an examination on or after October 1 of any year “may receive a license for the remainder of the year by paying one-half of the usual license fee for that classification of license” (G.S. 87-22). Late renewal adds a $25 processing fee if the renewal is not received before January 31 (G.S. 87-22). A license issued without a Board examination carries a $30 initial application fee (21 NCAC 50 .1102(c)).

Exam

All licensing examinations are computer-based and administered by PSI Services LLC. After the Board approves the application, the applicant receives an authorization letter with a 90-day window to schedule and sit the exam through PSI; NC PSI test centers are in Asheville, Charlotte, Fayetteville, Greenville, Raleigh, Wilmington, and Winston-Salem. A heating contractor exam runs 4.0 hours plus a 1.5-hour Business and Law exam; the Fuel Piping Contractor exam runs 2.0 hours and the Heating Technician exam 4.0 hours (technicians take no Business and Law exam). Examinations “are based upon a maximum obtainable grade of 100 points, and a grade of 70 is required to pass” (21 NCAC 50 .0305). A failed exam requires a 90-day wait and a Re-Examination Application before retesting.

Renewal & continuing education

Annual. Under G.S. 87-22 all licenses expire on the last day of December each year following issuance or renewal; the Board states there is no grace period and all activities requiring a license must cease until the license is renewed. A $25 processing fee applies if the renewal is not received before January 31. A license may be reinstated within three years of expiration (21 NCAC 50 .0409); after three years the Board requires reexamination (G.S. 87-22). None required. The Board eliminated its mandatory continuing-education requirement effective December 31, 2012, and CE is not a condition of annual renewal (the Board still encourages voluntary continuing education). Board-ordered Disciplinary Education courses may be required only after a rule violation.

Frequently asked questions

Do you need a license to do HVAC work in North Carolina?

Usually — but not for every job. A license must be obtained before anyone engages in, or offers to engage in, the business of heating contracting, and the credential is a contractor license by heating group (H-1, H-2, or H-3) plus fuel piping (G.S. 87-21(b)(3)). G.S. 87-21(c) exempts minor repairs and minor replacements to an already installed heating or air-conditioning system: replacing parts — the statute names a compressor, coil, contactor, motor, or capacitor — where the work requires no change in energy source, fuel type, or the routing or sizing of venting or piping. The exemption is defined by scope, not by price; Chapter 87, Article 2 sets no dollar threshold. Installing or replacing condensing units, air handlers, gas furnaces, package units, boilers, water heaters, or heat exchangers is licensed work. Separately, a bona fide employee of a licensed firm is not required to hold an individual license (G.S. 87-25).

What are North Carolina's heating license classifications?

Heating Group No. 1 covers “wet”/water-based comfort heating systems; Heating Group No. 2 covers forced-air heating/cooling systems with a mechanical refrigeration capacity in excess of 15 tons; Heating Group No. 3 covers forced-air heating/cooling systems of 15 tons or less. The tonnage split does not decide houses: under G.S. 87-21(a)(3), “Systems installed in single-family residences are included under heating group number three, regardless of size” — so a system over 15 tons in a single-family residence is Heating Group 3 work. H1-II and H3-II Class II licenses are limited to single-family detached dwellings. Fuel Piping (FP) covers fuel gas piping from an approved source to equipment inside the premises.

How much experience do you need for a North Carolina heating contractor license?

2 years (4,000 hours) of on-site full-time experience installing, maintaining, servicing, or repairing heating systems in the category sought. Up to one-half (2,000 hours) may be academic or technical training directly related to the field.

How much does a North Carolina heating contractor license cost?

The exam fee is $150 per exam (non-refundable). The initial license activation fee is $150 for a contractor classification, or $75 for a technician classification, and the annual license fee is $150 for a contractor license or $75 for a technician license. A contractor listed as the second or subsequent qualifying individual on a firm’s license pays $75 a year (21 NCAC 50 .1102(d)). Note that the Board’s rule and its 2026 renewal invoice state opposite conditions for the $75 technician rate — the rule ties it to technicians listed UNDER a licensed contractor, the invoice to technicians NOT listed under one — so confirm your rate with the Board. If you pass the exam on or after October 1, you pay one-half of the usual license fee for the remainder of that year (G.S. 87-22). A $25 processing fee applies if renewal is not received before January 31.

Who administers the North Carolina heating contractor exam?

All examinations are computer-based and administered by PSI Services LLC. After the Board approves the application, you receive a 90-day authorization window to schedule the exam at a PSI test center (Asheville, Charlotte, Fayetteville, Greenville, Raleigh, Wilmington, or Winston-Salem). Contractor applicants also take a 1.5-hour Business and Law exam.

Does North Carolina require continuing education for heating contractors?

No. The Board eliminated its mandatory continuing-education requirement effective December 31, 2012, and CE is not a condition of annual renewal. The Board still encourages voluntary continuing education, and may order Disciplinary Education courses after a rule violation.

How long do you have to activate a North Carolina heating license after passing the exam?

45 days. The Board’s License Activation Form states that it “is due within 45 days of passing the exam or you must re-test” — missing the deadline means retaking the examination, not merely paying late.
