How do I verify a HVAC contractor is licensed in Montana?
Montana does not license HVAC as a standalone trade, but contractors must register with the Montana Department of Labor & Industry as an Independent Contractor or Construction Contractor, and gas-fired HVAC work requires a Journeyman or Master Plumber license through the Board of Plumbers. Verify at ebiz.mt.gov/POL — confirm Active status, current workers' compensation coverage, and any municipal mechanical permits (Billings, Missoula, Bozeman each require local inspection).
Licensing verified weekly. Reviews refreshed within the last 30 days.
