Wyoming HVAC license requirements, reciprocity and contract rules.

This page lists what Wyoming publishes about licensing an HVAC or mechanical contractor and contracting with homeowners: who issues the license, whether one is required statewide, the classes and qualifications, insurance or bond minimums, reciprocity with other states, renewal and continuing education, and the state's home-improvement contract statute if it has one.

It is built for owners of residential HVAC companies, especially those hiring across a state line or opening a second territory. Every entry is a snapshot of what the cited source published on the verification date; it is a research starting point, not legal advice.

Wyoming, field by field.

Contractor licensing authority

No state agency licensing HVAC or mechanical contractors was located: Wyoming Statutes Title 33 (Professions and Occupations), read on 2026-10-20, contains no chapter licensing HVAC, mechanical, plumbing, or general contractors (its contractor chapter is chapter 42, the 'Water Well Drilling Contractors and Water Well Pump Installation Contractors Act'), and the Wyoming Department of Fire Prevention and Electrical Safety licensing page lists electrical licenses only (apprentice, journeyman, master, low voltage and limited technicians, electrical contractor, low voltage/limited contractor). The electrical portion of HVAC work is licensed statewide by that Department under W.S. 35-9-101 through 35-9-130. Local level: the Department's 'Local and State Jurisdictions' chart (updated 9/11/2026) shows which municipalities and counties enforce fire, building, and electrical inspections and plan review ('L - MUNICIPALITY/COUNTY ENFORCES'; 'S - STATE ENFORCES') and has no HVAC or mechanical licensing column. One city source was read: the City of Gillette contractor license application requires a City 'CLASS D-HVAC CONTRACTOR' license and states that 'All Master, Journeyman, and Apprentice HVAC Technicians are required to be licensed individually with the City'. Who licenses HVAC work in other cities and counties: Not verified — no state source lists local HVAC licensing.

HVAC license required

No state HVAC or mechanical contractor license was located: none appears in Title 33 or in W.S. 35-9 (Title 35), and the Department licenses electrical trades only. The electrical component of HVAC work is licensed statewide: W.S. 35-9-123(a)(viii)(A) authorizes the chief electrical inspector to issue a limited electrical contractor's license for 'Installation, repair or remodel of heating, ventilating and air conditioning systems limited to wiring on the load side of the equipment disconnect', with the work done by licensed limited technicians or registered limited apprentice technicians, and the Department lists the LM-H limited technician license for 'Limited electrical work for heating, ventilating and air conditioning systems limited to electrical work on the load side of the equipment disconnect'. Local: the City of Gillette requires a City Class D-HVAC contractor license and states 'Licensing is required regardless of the project size, duration, and whether or not a permit or inspection is required' (City of Gillette contractor license application; Gillette City Code ch. 5). Whether other cities or counties require an HVAC or mechanical license: Not verified.

License classes & qualifications

No state HVAC license class exists in the sources read. Electrical component: a 'Limited technician' is 'a person licensed by the department who has met the minimum experience requirements as prescribed by board rules and regulations in the portion of the electrical wiring industry covered by his limited license' (W.S. 35-9-102(a)(xi)); a 'Limited electrical contractor' is a person 'licensed by the department to contract with another to plan, lay out and supervise the installation of electrical equipment associated with the type of limited electrical contractor license held' (W.S. 35-9-102(a)(x)); an applicant who 'is qualified, successfully completes the examination and pays the required license fee shall be issued the proper license' (W.S. 35-9-126(a)); the Department lists 4,000 hours for the LM-H license; license fees are set by the department but 'shall not exceed' $200.00 for a limited electrical contractor's license and $100.00 for a limited technician's license (W.S. 35-9-129(a)), and the Department lists a $100.00 initial technician license fee and a $200.00 low voltage/limited contractor fee. The Electrical Board rules (hosted on Google Drive) were not read. Local: Gillette's Class D-HVAC contractor must designate a Master of Record who is 'licensed with the City as a Master HVAC Technician', and one Master or Journeyman HVAC Technician supervises every three Apprentice HVAC Technicians (Gillette application). Classes in other localities: Not verified.

Insurance / bond minimum

No state insurance or bond minimum was located: no state HVAC license exists in the sources read, and W.S. 35-9-119 through 35-9-130 contain no insurance or bond requirement for limited electrical contractors. Local: the City of Gillette requires a certificate of general liability insurance with minimums (per occurrence/total aggregate) of '$300,000/$600,000' for Class C, Class D, and Class F contractors (Gillette application).

Reciprocity

No HVAC reciprocity exists to describe (no state HVAC license). Electrical: the Department lists a reciprocal Journeyman Electrician license agreement with Alaska, Arkansas, Colorado, Idaho, Maine, Minnesota, Montana, Nebraska, New Hampshire, New Mexico, North Dakota, Oklahoma, Oregon, South Dakota, Texas, Iowa and Utah, and a reciprocal Master Electrician agreement with Idaho, South Dakota, and Iowa, and states 'Reciprocation only exempts you from the exam not licensure requirements'; no reciprocity is listed for limited technician (LM-H) licenses.

Renewal & continuing education

No state HVAC license to renew. Electrical: 'A master license, low voltage technician license and limited technician license shall expire on July 1 in the third year following the year of issue', and a licensee 'may renew his license by paying fifty percent (50%) of the proper license fee' (W.S. 35-9-126(a), (b)); W.S. 35-9-126(b) requires master and journeyman electricians to show at least sixteen hours of training at renewal and sets no continuing-education hours for limited technicians; the Department lists a $50.00 renewal fee and a $50.00 late fee for low voltage and limited technicians and a 45-day grace period for renewal, and states that 'All low voltage/limited electrical contractor licenses will expire on July 1 next following the date of issue'. Local: Gillette contractor licenses 'are issued for a term of one year and are renewed ANNUALLY' (Gillette application).

Home-improvement contract rule

No Wyoming statute requiring a written home-improvement contract, capping deposits, or registering home-improvement contractors was located in Titles 33, 35, or 40 of the Wyoming Statutes, and the Attorney General's Consumer Protection and Antitrust Unit pages contain no home-improvement guidance. Related provisions: W.S. 40-12-104 (home solicitation sales) — for a sale or lease of merchandise for cash exceeding $25 solicited at the buyer's residence in person or by telephone, 'the buyer has the right to cancel a home solicitation sale until midnight of the third business day after the day on which the buyer signs an agreement or offer to purchase' (§ 40-12-104(b)), the same three-business-day window as the federal rule (16 C.F.R. § 429.1); the period does not begin until the buyer is furnished a copy of the contract, the cancellation address, and a written statement of the right to cancel (§ 40-12-104(d)); the seller may retain a cancellation fee of 'five percent (5%) of the cash price but not exceeding the amount of the cash down payment' (§ 40-12-104(e)(iii)), and a seller that performed services before cancellation 'is entitled to no compensation except the cancellation fee' (§ 40-12-104(h)); W.S. 40-14-251 (Uniform Consumer Credit Code) defines a home solicitation sale as a consumer credit sale of goods or services with a purchase price of $25 or more; W.S. 40-12-105 lists unlawful practices; W.S. 40-12-701 et seq. (Exterior Storm Damage Repair Contracts) applies to contractors that repair or replace 'roof, siding or gutter systems', not HVAC.
