South Carolina to North Carolina: master HVAC technician license reciprocity
North Carolina has a specific endorsement rule for South Carolina master HVAC technicians.

Technical examination waiver agreement with South Carolina (HVAC contractor licenses)
The board reviews your out-of-state credentials case by case. Some exam is usually still required, often only a law or code exam.
North Carolina's only HVAC exam-waiver agreement is with South Carolina. A holder of an active South Carolina contractor license who personally took and passed the South Carolina technical examination is excused from the North Carolina technical section of the exam for the matching classification: SC Residential HVAC (Residential Builders Commission) qualifies for Heating Group 3 Class II; SC Commercial Mechanical Heating (HT) for Heating Group 1 Class I; SC Commercial Mechanical Air Conditioning (AC) for Heating Group 2 and Heating Group 3 Class I; and SC Commercial Mechanical Packaged Equipment (PK) for Heating Group 3 Class I. The Board stresses this is not license reciprocity: the applicant completes the whole North Carolina application, documents the 4,000 hours of North Carolina-required experience, pays the $150 examination fee, submits the background report, and must still take and pass the North Carolina Business and Law section. The applicant asks the SC Residential Builders Commission ([email protected]) or the SC Contractor's Licensing Board ([email protected]) to complete a License Verification and email it to the NC Board, and checks the SC Technical Exam Waiver box on Form PHFP-1. South Carolina is also one of the five states covered by the Neighbor State License Recognition Act, which waives the exam entirely for applicants who have moved to North Carolina.

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.
