Hawaii to New Mexico: master HVAC technician license reciprocity

New Mexico has no 'master HVAC' license. Its highest heating and cooling credential is the MM-3 Heating, Ventilation and Air Conditioning contractor classification (install, alter, repair, service and maintain HVAC air-handling and refrigeration equipment, piping and ductwork, with controls at 24 volts or less); the broader MM-98 Mechanical classification covers MM-3 plus plumbing, gas fitting and process piping. CID issues the contractor's license to the contracting entity and a personal, non-transferable certificate of qualification to the qualifying party, the individual who passed the MM-3 trade exam and the Contractor's Business and Law exam, so this site maps the MM-3 qualifying party to the master level. A qualifying party needs four years of experience in the classification within the ten years before application. Even with an MM-3 license the hands-on work must still be done by or under a certified JR or JSM journeyman. CID publishes reciprocity only for EE-98J electrical journeymen; no reciprocity or exam waiver is published for mechanical qualifying parties or contractors, although NMSA 60-13-14(C) allows the division to enter into reciprocal agreements with states having equivalent requirements.

Hawaii issues no master HVAC or master refrigeration license. The highest HVAC credential is a Contractors License Board specialty license in classification C-52 Ventilating and Air Conditioning (warm-air heating, cooling, ventilating and air-conditioning systems, including heat pumps) or C-40 Refrigeration (below 50°F), issued to a sole proprietor or to a contracting entity that qualifies through a responsible managing employee (RME); an RME holds a personal license number but may contract only for the employing entity and the principal RME must live in Hawaii while the license is active, so the credential functions as a business license rather than a master's card. A master HVAC licensee who only wants to work for an employer needs no Hawaii license. To contract, the sole proprietor or RME must document at least four years of supervisory experience as a foreman, supervising employee or contractor within the past ten years with three notarized experience certificates and a project list, file the $50 application with a CPA financial statement, credit report and tax clearance for Board review at a monthly meeting, then pass the PSI-administered Part I Business and Law and Part II trade exams within six months of approval; on passing, the licensee provides liability insurance (at least $100,000 per person and $300,000 per occurrence bodily injury and $50,000 property damage), workers' compensation coverage, a Hawaii place of business and the license fee, and renews by September 30 of even-numbered years ($338 entity or sole proprietor, $208 RME for 2026-2028). The Board's FAQ states that Hawaii has no reciprocity agreements with any state and that all applicants must meet the same licensing and examination requirements; an out-of-state contractor or master license is accepted only as supporting proof of experience, and HAR §16-77-41 waives the exam solely for someone who already passed the Hawaii exam in the same classification within four years. The 2018 FAQ listed the exam fee at $75 per part and initial license fees of $663 (entity or sole proprietor) and $438 (RME) in the first year of the biennium, which the current form no longer prints. EPA Section 608 certification remains a separate federal requirement for handling refrigerants.
