Hawaii 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.

Hawaii does not license journeyman HVAC mechanics, HVAC technicians or refrigeration technicians. The Department of Commerce and Consumer Affairs licenses only contractors for this work, through the Contractors License Board's specialty classifications C-52 Ventilating and Air Conditioning Contractor and C-40 Refrigeration Contractor (systems below 50°F), and its directory of boards and programs contains no HVAC or refrigeration technician program; the Board of Electricians and Plumbers licenses only electricians and plumbers. HRS §444-9.5 obliges electrical and plumbing contractors to employ individually licensed workers, but no equivalent rule applies to ventilating, air-conditioning or refrigeration contractors, so their mechanics work under the contractor's license without any personal credential, and no county trade license was found. An out-of-state journeyman or HVAC technician license therefore has nothing to transfer to in Hawaii and is neither required nor recognized for employment, although the Board will accept it as proof of licensure alongside supervisory experience when the holder later applies for a contractor license. EPA Section 608 technician certification is a federal requirement for anyone handling refrigerants and applies in Hawaii as everywhere else. A mechanic who wants to contract independently must qualify for a C-52 or C-40 license, described at the master level.
