New Hampshire to North Carolina: journeyman HVAC technician license reciprocity

North Carolina has no license called 'journeyman HVAC'. The closest state-issued, person-held credential below contractor level is the Heating Technician license from the State Board of Examiners of Plumbing, Heating and Fire Sprinkler Contractors: an individual who has passed the 4-hour technical examination for Heating Group 1 (hydronic), Group 2 (forced air over 15 tons) or Group 3 (forced air 15 tons or less), Class I (any building) or Class II (single-family dwellings), but not the business and law examination. A technician license is not a contracting license and is not required to work for a living: any W-2 employee of a licensed heating contractor may perform work under the contractor's license, so the technician license mainly lets its holder be listed as a sub-licensee to help supervise work, or qualify a state, local-government or private-school maintenance department. Eligibility is 3,000 hours of hands-on installation, maintenance, service or repair experience (up to half from technical education), a $150 exam fee, a nationwide criminal background report and Social Security verification. The Board publishes no reciprocity for any state at this level; an out-of-state journeyman documents their hours on the Board's employment-history form and takes the technical exam. Refrigeration (commercial, industrial, transport and service, but not comfort cooling) is licensed separately by the State Board of Refrigeration Contractors, which licenses only contractors and has no technician-level credential. EPA Section 608 certification is required federally to handle refrigerants.

New Hampshire does not license journeyman HVAC, air conditioning or refrigeration technicians at the state level, and the Office of Professional Licensure and Certification (OPLC) has no board for the trade; its Mechanical Licensing Board, despite the name, regulates only fuel gas fitters (installation, service, piping, domestic appliance and hearth technicians, plus trainees), plumbers and mechanical business entities, and offers a voluntary $50 Oil Heating Technician certification under RSA 153:16-b. The plumbing statute expressly exempts plumbing done in connection with the installation of heating, cooling, air conditioning and domestic water heating systems (RSA 153:36, VII), so an HVAC technician needs no plumber license either. No New Hampshire city or town was found to license HVAC technicians; local building departments issue mechanical permits but do not require a personal HVAC credential. What an out-of-state technician does need is a Fuel Gas Fitter license before connecting or servicing natural gas or propane furnaces, boilers or piping: the categories cost $198 for two years ($176 for domestic appliance), require 40 to 140 classroom hours, 1,000 to 2,000 on-the-job hours and a 70% score on the Prov exam, and an out-of-state gas or plumbing license only makes the holder eligible to sit that exam (Saf-Mec 302.14); OPLC's endorsement rule Plc 313.34 covers the gas fitter categories in principle but the qualifying-jurisdiction lists are still 'TBD'. An out-of-state journeyman HVAC license itself has no New Hampshire equivalent to transfer to. Federal EPA Section 608 certification is required to handle refrigerants.
