Hawaii to Oklahoma: master HVAC technician license reciprocity

Oklahoma has no 'master HVAC' license; its highest person-held HVAC credential is the Mechanical Contractor license, which CIB issues to an individual who passes the two-part contractor exam (technical trade and Mechanical Business and Law, 70% each, $92 per portion). This site maps the HVAC/R Unlimited (or Limited) Mechanical Contractor license to the master level. An applicant needs the journeyman qualifications plus one additional year, so four years (8,000 hours) of verifiable experience in the category, and pays $330 ($30 application plus $300 initial license). After passing, an inactive license issues until the contractor files a $5,000 corporate surety bond and a $50,000 commercial general liability certificate with CIB; an inactive contractor may work as a journeyman. Every mechanical firm must have a licensed contractor associated with and responsible for its work. OAC 158:50-9-6 lets CIB sign contractor reciprocity agreements, under which the applicant would still have to pass the Business and Law portion, but CIB publishes no mechanical partner states. Licenses renew annually ($200) with six hours of continuing education every 36 months.

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.
