How to get licensed

  1. 1

    Meet the prerequisites

    Be at least 18 years old, pass a criminal background check. Under G.S. 87-21, examination applicants must be at least 18 years of age. All applicants are required to obtain a nationwide criminal background record report through CastleBranch.com and submit a printed copy with their application; providing false or inaccurate background information can be grounds for license denial and prosecution under G.S. 87-23/87-25. [4]

  2. 2

    Complete approved training

    Complete 4000 hours of training. North Carolina does not license individual HVAC technicians directly for independent work; licensure applies at the contractor/business level via the State Board of Examiners of Plumbing, Heating, and Fire Sprinkler Contractors. Heating Group 3 (H3) covers forced-air heating/cooling systems (typical residential/light-commercial HVAC) with cooling capacity of 15 tons or less; H3-I (recorded here) allows work in any building (residential, commercial, industrial), while H3-II is limited to single-family detached dwellings. Other classifications exist: Heating Group 1 (wet/water-based comfort heating systems) and Heating Group 2 (forced-air systems over 15 tons cooling capacity). The Board also issues a lower-tier 'Technician' license (Heating Group 3 Technician) requiring the same technical exam but not the business/law exam; the Contractor license is recorded as the primary path since it authorizes independent contracting. Applicants must document 4,000 hours (2 years) of hands-on experience in installation, maintenance, service, or repair of qualifying systems; up to 50% of this may be satisfied through directly-related college/university/community-college coursework (each approved semester hour = 66.66 hours of credit), so a formal approved program is not strictly required. [1]

  3. 3

    Heating Group 3 - Class I Contractor Examination (technical + Business and Law)

    Pass the Heating Group 3 - Class I Contractor Examination (technical + Business and Law). Computer-based, at PSI testing centers throughout North Carolina; technical portion 4.0 hours plus Business and Law portion 1.5 hours (waived if the applicant already holds an active contractor license with the Board and passed the Business and Law exam after August 2003) The Board's current (2026-06) Contractor Application packet states the exam cost is '$100 per exam payable by check or money order.' The Board's FAQ page separately states 'the examination application fee is $150.00 and is non-refundable' -- this figure appears to actually describe the $150 annual license/activation fee rather than the exam fee (the same $150 figure recurs on the Board's License Activation form and 2026 renewal invoice as the per-license fee), so the more specific, current Contractor Application PDF's $100 exam fee is used here. A $25 fee applies to review a failed exam before retesting (90-day wait required). Fee recorded as null here to avoid double-counting the same charge twice in this record's upfront-cost total: the $100 is a combined application/examination fee and is already counted under the application fee. [1]

  4. 4

    Submit your application

    Submit your application to North Carolina State Board of Examiners of Plumbing, Heating, and Fire Sprinkler Contractors with the $100 application fee. Typical processing time: Application processing currently averages about 4-6 weeks (the Board notes it receives 250+ applications per month); once approved, applicants have a 90-day authorization window to schedule and take the PSI exam.. [5]

  5. 5

    Receive your license

    Once your application is approved, North Carolina State Board of Examiners of Plumbing, Heating, and Fire Sprinkler Contractors issues your Heating Group 3 - Class I Contractor License (H3-I) for North Carolina.

Fees

Fee Amount
Application fee [2] $100
License fee [2] $150
Renewal fee [2] $150
Heating Group 3 - Class I Contractor Examination (technical + Business and Law) [1] None specified
Late renewal processing fee (after January 31) [2] $25

The $100 application/exam fee is paid with the exam application (Contractor Application packet, 2026-06). Upon passing, a License Activation Form and $150 fee (Heating Group 3 Class I Contractor) must be submitted within 45 days. Renewal is annual at $150/year (2026 Invoice for Renewal of State License); a $25 late processing fee applies if renewal is not received before January 31.

Renewal & continuing education

Renew every 1 year.

All licenses expire on December 31 each year and must be renewed annually (G.S. 87-22); there is no grace period. The mandatory continuing-education requirement for renewal was eliminated December 31, 2012, and replaced with a voluntary 'Disciplinary Education' encouragement -- the Board confirms on its FAQ page that CE is not required for renewal.

Reciprocity

Endorsement/reciprocity from another state is available.

North Carolina does not have broad license reciprocity. Under G.S. 87-21(g), the Board may in its discretion waive the written exam for contractors already licensed in another state if that state's qualifications are found substantially equivalent -- currently the Board recognizes only a Technical Examination Waiver Agreement with South Carolina (e.g., an active SC Residential HVAC license may waive the NC Heating Group 3 - Class II technical exam), and the NC Business and Law exam must still be passed. Separately, military veterans and military spouses may qualify for licensure without examination under G.S. 93B-15.1 by demonstrating substantially equivalent training/experience and paying a $30 application fee plus $150 annual license fee. HVAC has no known interstate licensing compact.

Frequently asked questions

Does North Carolina license individual HVAC technicians?

Not directly for independent work. The State Board of Examiners of Plumbing, Heating, and Fire Sprinkler Contractors licenses HVAC work at the contractor/business level, primarily through the Heating Group 3 (H3) classification for forced-air heating/cooling systems of 15 tons or less. A lower-tier Technician license is also available for those working under a licensed contractor.

What experience is required to sit for the Heating Group 3 exam?

4,000 hours (about 2 years) of documented hands-on experience installing, maintaining, servicing, or repairing qualifying heating/cooling systems. Up to half of that experience may be satisfied through directly-related coursework at a college, university, community college, or technical institute.

Who administers the North Carolina heating contractor exam?

PSI Services LLC administers the computer-based exam at testing centers across North Carolina, including a technical portion and a Business and Law portion (the latter can be waived for applicants who already hold an active Board contractor license and passed Business and Law after August 2003).

How often must the license be renewed, and is continuing education required?

Licenses expire every December 31 and must be renewed annually for $150 (a $25 late fee applies after January 31). North Carolina eliminated its mandatory continuing-education requirement for renewal in 2012.

Is there reciprocity with other states?

North Carolina does not have broad reciprocity, but it has a technical-exam waiver agreement with South Carolina for certain HVAC/mechanical license holders (the NC Business and Law exam is still required), and separate no-exam pathways exist for qualifying military veterans and military spouses.
