Checking an HVAC company in the Cheyenne area

HVAC licenses in Wyoming

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.

Sources: wsfm.wyo.gov, wsfm.wyo.gov, cheyennecity.org, cheyennecity.org. Checked October 2026 from official sources. This is not legal advice.

Questions to ask

Ask every company the same questions: license number, insurance, EPA refrigerant certification, a written itemized estimate, a load calculation for new equipment, after-hours rates, who pulls the permit, and the warranty. All eight questions.

Seasonal care

Getting through a Cheyenne winter

Heating season is the long one in Cheyenne, so the furnace, boiler or heat pump does most of the work. Start with these before the first cold snap – and keep carbon monoxide alarms working.

Furnace maintenance: a fall checklist for safe heatA gas furnace burns fuel inside your home, so fall maintenance is about safety as much as comfort. Here is what to do yourself and what the yearly professional inspection should cover.Furnace not working? What to check firstA furnace that will not start is often stopped by a safety switch doing its job. Here is how to find which one – and when to leave the house instead.How to prevent frozen pipes: before and during a freezeWater expands as it freezes, and that pressure can split a pipe. A few steps before winter and during cold snaps prevent most frozen pipes, and the right response limits damage when one freezes anyway.Carbon monoxide and your furnace: alarms, warning signs and what to doCarbon monoxide is a poisonous gas you cannot see or smell. Fuel-burning furnaces, boilers and water heaters can produce it when something goes wrong. Alarms and yearly inspections are the main defenses.Heat pump maintenance: year-round care in both seasonsA heat pump heats in winter and cools in summer, so it runs more of the year than an AC or a furnace alone. Simple upkeep matters in every season, especially keeping the outdoor unit clear of snow and ice.Furnace smells like burning? What the smell means and what to doMost furnaces give off a faint smell the first time they run each fall. A few smells mean turn the system off now, and one means get out of the house. Here is how to tell them apart.
