Oklahoma to North Carolina: master HVAC technician license reciprocity
North Carolina has no reciprocity agreement with Oklahoma. Your Oklahoma experience counts toward eligibility, but you must pass the North Carolina exam.
Reference only, not legal advice. Rules change; confirm with the licensing board before you apply. Full disclaimer.
Out-of-state master HVAC or HVAC contractor without a waiver (all other states)
Nothing is waived, but your documented out-of-state hours count toward eligibility to sit the exam.
The Board's 2026 application packet states that there is no license reciprocity, that all applicants must meet the North Carolina experience requirements, and that 'there are currently no other waivers available for any other states or any other licenses' beyond South Carolina. G.S. 87-21(g) lets the Board license contractors from other states without written examination after 'a complete and exhaustive review' finding the other state's requirements substantially equivalent, but the Board has exercised that authority only for South Carolina. A master HVAC technician or HVAC contractor from any other state therefore applies to sit the examination: 4,000 hours of hands-on experience in the heating group sought (up to half from college or technical-institute coursework), which may have been earned anywhere and is documented on the Applicant Employment History form (1-C) with W-2s or 1099s when it was not earned under a North Carolina licensee. The $150 exam fee, a Disahealthcare criminal background report and Form SSA-89 are submitted with the application; after approval (4-6 weeks) the candidate schedules the 4-hour technical exam and 1.5-hour Business and Law exam with PSI. An applicant who passes the technical portion but fails the business portion may take a Heating Technician license instead. A North Carolina resident licensed in Georgia, Tennessee, Virginia or West Virginia may instead use the Neighbor State License Recognition Act (see agreements).
Separate application and fee for each heating classification. An H3-I licensee gets 50% experience credit toward H2 and vice versa.

How North Carolina licenses master HVAC technicians
North Carolina master HVAC technician · “Heating Contractor (H1-I / H1-II, H2, H3-I / H3-II)”
Statewide license
Issued by North Carolina State Board of Examiners of Plumbing, Heating and Fire Sprinkler Contractors
North Carolina has no 'master HVAC' license; its highest HVAC credential is the Heating Contractor license issued to an individual by the State Board of Examiners of Plumbing, Heating and Fire Sprinkler Contractors under G.S. 87-21, in Heating Group 1 (steam, vapor and hot-water comfort heating), Group 2 (forced-air heating/cooling with more than 15 tons of cooling) and Group 3 (forced-air heating/cooling of 15 tons or less), each with Class I (any building) and Class II (single-family detached dwellings) except Group 2, which is Class I only. The license is earned personally by passing the 4-hour technical exam and the 1.5-hour Business and Law exam and belongs to the individual, who may list it in a firm name and add sub-licensees; that is why this site maps it to the master level. A new applicant needs 4,000 hours of hands-on experience (up to half from technical education), pays $150 per examination, submits a nationwide criminal background report and Social Security verification, and after licensure pays an annual license fee of $150. The Board states that it has no license reciprocity with any state; the only technical-exam waiver is with South Carolina, and North Carolina residents licensed in Georgia, South Carolina, Tennessee, Virginia or West Virginia may ask for licensure without examination under the Neighbor State License Recognition Act. Commercial, industrial, transport and service refrigeration (not comfort cooling) requires a separate Class I-IV Refrigeration Contractor license from the State Board of Refrigeration Contractors ($100 exam, 4,000 hours, EPA 608 Type II or Universal required), which has no reciprocity but offers the same neighbor-state route to new NC residents. EPA Section 608 certification is required federally to handle refrigerants.
