Vermont 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.

Vermont has no master HVAC, HVAC contractor, mechanical contractor or refrigeration contractor license and no statewide general contractor license, so a person or firm may install and service heating, cooling, ventilation and refrigeration systems without any state HVAC credential; no Vermont city was found to license the trade either. The credentials that do apply have no master tier: the Division of Fire Safety's gas certification (LP, natural gas or both, $60 for three years, NPGA or AGA training plus the Vermont Energy Goals module) and oil burner installer certification ($60 for three years, NORA Silver or Gold for full installation, Bronze for limited service) are required of every individual who installs, inspects or services fuel-burning equipment under 20 V.S.A. s. 2731, and the Type-S Specialist electrician license in field C3 (refrigeration or air conditioning, air-to-air heat pumps) or A1 (automatic gas or oil heating, ground-source heat pumps) lets a licensee wire that equipment 'as an employee or an independent contractor' for $115 per field, which is the closest thing Vermont has to an HVAC contractor credential. None of these recognizes an out-of-state HVAC or mechanical contractor license: the gas and oil certifications are issued on the national training certificates alone, and the Type-S reciprocity on the electrical application is limited to Maine and New Hampshire electrical licensees. A master HVAC licensee arriving from another state therefore has nothing to transfer; they need federal EPA Section 608 certification for refrigerant work, the gas or oil certification for fuel-burning equipment, a Type-S (or journeyman/master electrician) license for the wiring, and local permits.
