Not regulated at state level
Individual Wyoming municipalities + U.S. EPA (Section 608) →No Statewide HVAC License
Wyoming does not issue a statewide HVAC contractor or technician license. The Department of Fire Prevention and Electrical Safety licenses only electrical work. HVAC and mechanical work is regulated by the city where the work is performed, plus federal refrigerant law.

EPA 608 (Federal). Under 40 CFR Part 82, Subpart F, technicians who maintain, service, repair, or dispose of equipment that could release ozone-depleting refrigerants or their substitutes must hold an EPA Section 608 certification (Type I, II, III, or Universal). EPA states that Section 608 credentials do not expire. Source: EPA Section 608 (https://www.epa.gov/section608/section-608-technician-certification).
Municipal Licensing
Wyoming cities handle HVAC and mechanical licensing at the local level. Cheyenne, Casper, Laramie, Gillette, Rock Springs, Sheridan, Jackson, and smaller communities each set their own contractor registration, exam, and permit rules. Some cities require a mechanical-contractor exam with insurance; others require only a business registration. Before quoting a job, call the code-enforcement or building-department office in the city or county where the work will occur.
Apprenticeship
Wyoming has a Registered Apprenticeship program administered through the U.S. Department of Labor Office of Apprenticeship. UA Local 192 (Cheyenne) and UA Local 59 (Casper area) run joint apprenticeships that include HVAC/refrigeration scope. Sheet Metal Workers Local 9 and Local 103 cover sheet metal and HVAC duct work in parts of Wyoming. Non-union shops and community-college HVAC programs also lead to qualifying experience for EPA 608 and municipal licensure.
Verification Advice
Before accepting HVAC work in Wyoming, confirm four things in writing: (1) EPA 608 certification matching the equipment type, (2) any municipal mechanical or contractor license in the city where the job sits, (3) Wyoming workers' compensation coverage through the Wyoming Department of Workforce Services (required for nearly all construction employers under Wyoming Statute 27-14-108), and (4) general liability insurance at the level your contracts require.
