Utah 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.

Utah has no master HVAC license. The state credential for HVAC work is the H100 HVAC Contractor classification (formerly S350) issued by DOPL to a business entity or sole proprietorship, not to the technician personally, so a master HVAC licensee from another state who only wants to work for an employer needs no Utah license at all. To contract independently the applicant's business applies for an H100 license with a qualifier who passes the H100 written trade exam and the Utah Business and Law exam (both through Prov), holds a Certified Natural Gas Technician certificate from the Rocky Mountain Gas Association or an equivalent, and documents 4,000 hours of HVAC employment in the past 5 years with W-2, K-1 or tax returns (an active Utah plumber license is an accepted alternative); the qualifier must also complete a 25-hour pre-licensure course and the 5-hour Business and Law course. The business registers with the Division of Corporations, carries general liability insurance of $1 million per occurrence and $2 million aggregate (the March 2026 application form still reads $3 million aggregate) and workers' compensation, and pays $50 per qualifier plus $175 per classification and a $1 surcharge. Utah has no HVAC reciprocity agreements, but DOPL grants licensure by endorsement to a contractor licensed for at least one year in good standing in a jurisdiction DOPL has determined equivalent, with at least 50% common ownership, and an endorsed applicant needs no additional courses or examinations; licenses from other jurisdictions can still be used to document part of the experience and exam requirements.
