How Wyoming licenses HVAC work
There is no statewide HVAC contractor license that we could find; cities or counties license HVAC work.
Local rules: We could not confirm a statewide HVAC contractor license in Wyoming, and we did not find an official page that states outright that none exists. The state Department of Fire Prevention and Electrical Safety site we read lists only electrical licensing (master and journeyman electricians, electrical and low voltage contractors; its Electrical Board authority is W.S. 35-9-103), and its pages do not mention plumbing, HVAC or mechanical licensing. We confirmed city-level licensing in two cities. Cheyenne: its Contractor Licensing Board regulations (March 2026 edition) define HVAC as Heating, Ventilating and Air Conditioning, place those trades in the tested Class C1 subcontractor license, require both a company license and a registered Individual Qualified Supervisor, and require job-site employees to hold master, journeyman or apprentice licenses; the Board describes its authority as coming from Wyoming statute allowing cities to license building contractors and certain building and professional trades. Casper: Community Development lists 'Plumbing, Mechanical, and Individual Contractor Licenses' (ICC exams, notarized experience affidavits, proof of insurance, Chief Building Official approval). We did not research other Wyoming cities or counties.
Ask for the license issued by your city or county building department (for example Cheyenne's company license plus qualified supervisor, or Casper's mechanical contractor license), confirm it with that office, and check that a permit is pulled.
Federal rule: in every state, technicians who handle refrigerant must hold EPA Section 608 certification, whatever the state or city requires.
We could not confirm every detail from Wyoming’s own sources, so treat this as a starting point and check with the agency.

Before you hire
Ask for the license number and check it on the official lookup where one exists. Ask for proof of insurance and a written, itemized estimate, and ask who pulls the permit if the job needs one – a new furnace, heat pump or air conditioner usually does.
