North Carolina HVAC / Mechanical Contractor License Cost & Requirements (2026)
North Carolina licenses HVAC work as heating contracting, through the same board that licenses plumbing: the State Board of Examiners of Plumbing, Heating and Fire Sprinkler Contractors. Nobody in the board's system holds an 'HVAC license' as such.
They hold a Heating Contractor license in one of three groups that divide the trade by the kind of system, Group 1 for wet heat, Group 2 for large forced-air work and Group 3 for the forced-air work most firms do, with classes that then divide each group by the buildings it may serve.
This page maps the three groups and both classes, on fees identical to the board's plumbing charges: a $150 examination application and a $150 license. It was rebuilt in October 2026 from the board's applicant information, its license definitions and its current forms, and it sits alongside this site's North Carolina plumbing page, which shares the same board machinery.

Warning: Unlicensed Contracting Penalties in North Carolina
Class 2 misdemeanor (§87-13). The Licensing Board can also ask a court to enjoin unlicensed practice (§87-13.1). A license is required for any project of $40,000 or more (§87-1).
Note: In many states, unlicensed contractors also lose the ability to file mechanic's liens or sue for non-payment in civil courts.
Special Statutory Notes for North Carolina
Licensed by the North Carolina State Board of Examiners of Plumbing, Heating and Fire Sprinkler Contractors under G. S. Chapter 87. North Carolina licenses heating work, and the license is styled a Heating Contractor license. Three groups divide the systems: Group 1 covers wet (water and steam) heating. Group 2 covers forced-air heating and cooling with a cooling capacity over 15 tons.
Group 3 covers forced-air systems up to 15 tons, and every single-family detached dwelling system falls in Group 3 whatever its size. Groups 1 and 3 are each split into Class I (any building) and Class II (single-family detached dwellings only). Group 2 has no classes. The groups include the associated fuel piping.
Eligibility mirrors the board's plumbing route: 2 years (4,000 hours) of on-site, full-time experience in the group sought, up to half from academic or technical training, plus a nationwide criminal record report obtained through CastleBranch. Technician licenses beneath the contractor require 18 months (3,000 hours) and cost $75. The examination, administered by PSI, pairs a Business & Law portion (1½ hours) with a 4-hour trade portion, open-book with approved references, 70% to pass.
The board's examination application fee is $150, and license activation on passing is $150. Licenses expire every December 31, renewal in January adds $25, reinstatement runs for three years, and the board abolished mandatory continuing education in 2012. A technical-examination waiver agreement exists with South Carolina (North Carolina Business & Law still required). The federal EPA Section 608 certification governs refrigerant handling on top of the state license.
North Carolina classifies contractor licenses by financial project limits: Limited ($750k), Intermediate ($1.5M), and Unlimited.
Three groups, two classes, and the 15-ton line
Heating Group 1 covers wet comfort heating: hot water and steam systems. Heating Group 2 covers forced-air heating and cooling systems with a cooling capacity in excess of 15 tons, the commercial end of the trade. Heating Group 3 covers forced-air systems of up to 15 tons, and, importantly, every single-family detached dwelling system belongs to Group 3 whatever its tonnage, so a large house does not push a residential firm into Group 2.
The groups include the fuel piping that serves the systems. Groups 1 and 3 are each split into Class I, which allows work in any building, and Class II, which allows work in single-family detached dwellings only; Group 2, being commercial by definition, has no classes.
The designation on the license therefore reads like a code, H3-I being the commonest in the trade: Group 3 systems, any building. Choosing wrongly has legal consequences in both directions. An H3-II holder who takes a restaurant job is working outside the license; an H2 applicant who only ever fits out houses has bought examination scope they did not need.
Beneath the contractor sits the heating technician license, group by group, for the contractor's listed workers: 18 months (3,000 hours) of experience for Class I groups, a $75 license fee, and no power to contract.
The board's shared machinery: experience, exam, activation
Heating applicants use the same route as the board's plumbers. Eligibility for a contractor examination requires 2 years (4,000 hours) of on-site, full-time experience in the installation, maintenance, service or repair of systems in the group sought, whether or not a license was required for that work, with up to half creditable from directly related academic or technical training (2,000 hours, or 45 quarter or 30 semester hours).
A nationwide criminal record report from CastleBranch goes in with the application. The board's posted average review time for a complete application is about six weeks.
The examination, through PSI, pairs a Business & Law portion (an hour and a half, contractors only) with a four-hour trade portion for the group, open-book with approved references, 70% to pass, and the board's examination application fee is $150.
The license is then activated within 45 days of passing for a $150 fee, with the board's half-fee courtesy for candidates who pass after October 1 and activate only for the rest of that year. On top of the state license, anyone who handles refrigerant in the work needs the federal EPA Section 608 certification in the appropriate category; the state license and the federal certificate govern different things and neither substitutes for the other.
Renewal, and what North Carolina does not require
Heating licenses expire on December 31 each year, in step with the rest of the board's system, and there is no grace period for licensed activity on an expired license. Renewal is $150 (technicians $75); renewal during January adds $25; reinstatement is available within three years on payment of the current and prior-year fees and processing charges, and after three years the examination must be retaken.
As with plumbing, there is no continuing education requirement: the board abolished mandatory CE in 2012, so renewal is a fee and a form, although the state mechanical code moves on regardless and keeping up with it remains the licensee's own responsibility.
Out-of-state heating contractors meet the same two doors as plumbers: the board's technical examination waiver agreement with South Carolina, under which the North Carolina Business & Law portion must still be passed, and the Neighbor State Licensing Recognition Act for new North Carolina residents holding licenses in Georgia, South Carolina, Tennessee, Virginia or West Virginia. There is no surety bond anywhere in this board's licensing.
Mistakes that delay a North Carolina HVAC application
- Reading Group 3's 15-ton line as applying to houses: every single-family detached system is Group 3 regardless of tonnage. Group 2 is for forced-air work over 15 tons in the commercial sphere.
- Holding Class II and taking commercial work: Class II in Groups 1 and 3 means single-family detached dwellings only.
- Treating the state license as covering refrigerant work by itself: EPA Section 608 certification is a separate federal requirement for handling refrigerants.
- Missing the 45-day activation window after passing the examination, or the December 31 renewal with its no-grace-period rule.
- Assuming continuing education is required because neighboring states require it: this board abolished mandatory CE in 2012.
- Letting technicians drift into contracting: a heating technician is a sub-licensee under a licensed contractor, not a contractor, whatever their experience.
North Carolina HVAC Licensing FAQ
What does a North Carolina heating contractor license cost in total?
In board charges, $300 in any group: the $150 examination application fee and the $150 license activation fee, due within 45 days of passing (halved for a post-October 1 pass activating for the remainder of that year). Renewal is $150 annually by December 31. A PSI candidate bulletin has listed $75 for this examination; the board's current examination FAQ and its 2026 exam applications put the examination application fee at $150, which is the figure used here. Heating technician licenses cost $75. There is no bond and no continuing education charge.
Which heating group do I need?
By system type. Group 1: wet heating, hot water and steam. Group 2: forced-air heating and cooling with cooling capacity over 15 tons. Group 3: forced-air systems up to 15 tons, and all single-family detached dwelling systems of any size. Groups 1 and 3 then split by class: Class I for any building, Class II for single-family detached dwellings only. Most residential and light-commercial HVAC firms hold H3-I.
How much experience does a North Carolina heating contractor need?
Two years (4,000 hours) of on-site, full-time experience installing, maintaining, servicing or repairing systems in the group sought, with up to half (2,000 hours) creditable from directly related academic or technical training. Technician licenses require 18 months (3,000 hours) for Class I groups. Experience counts whether or not a license was legally required where the work was done.
Does the North Carolina heating license cover refrigerant work?
The license authorizes the contracting; refrigerant handling itself is governed federally. Anyone who maintains, services, repairs or disposes of appliances with refrigerants needs EPA Section 608 certification of the appropriate type (Universal covers all categories). The board's license and the EPA certificate are separate requirements and both apply to a working HVAC business.
Does North Carolina require continuing education for HVAC contractors?
No. The State Board of Examiners of Plumbing, Heating and Fire Sprinkler Contractors eliminated mandatory continuing education in 2012 across its licenses. Renewal each December 31 is the $150 fee and the renewal form. There is no grace period for working on an expired license, January renewal adds $25, and reinstatement runs for three years before re-examination is required.
Can an out-of-state HVAC contractor get licensed in North Carolina?
South Carolina licensees can use the board's technical examination waiver agreement, passing only the North Carolina Business & Law portion. New North Carolina residents licensed in Georgia, South Carolina, Tennessee, Virginia or West Virginia may qualify under the Neighbor State Licensing Recognition Act. Other applicants take the standard route: 4,000 hours of experience evidence, the background report, and the two-part examination for their group.
