Hawaii to Wisconsin: master HVAC technician license reciprocity

Wisconsin's highest person-held HVAC credential is the HVAC Qualifier certification issued by DSPS under Wis. Stat. 101.178(3) and SPS 305.71, which this file treats as the master level. It is issued to an individual who documents at least 1,000 hours per year for four years of experience supervising or performing the design, installation, servicing or maintenance of HVAC systems (or four years of HVAC-related schooling, or a combination) and passes the open-book DSPS exam (70% to pass, 4 hours, $95 at Pearson VUE); the credential is renewed every four years for $60 with no continuing education. Certification is voluntary: the mandatory credential is the business-level HVAC Contractor registration, but a business that employs a qualifier is a 'certified HVAC business' that no city or village may require to obtain a local certification, license or other approval. DSPS publishes no reciprocity agreements and no licensure-by-endorsement route for HVAC qualifiers; the experience requirement is not restricted to Wisconsin, so out-of-state work counts toward eligibility, but every applicant takes the Wisconsin exam. Federal EPA Section 608 certification is separately required to handle refrigerants.

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.
