Montana has no state HVAC or mechanical contractor license: MCA Title 37, Chapter 70 (Board of Warm Air Heating, Ventilation and Air Conditioning) is repealed. HVAC firms are subject to the DLI Construction Contractor License (see general_contractor), the electrical license for any electrical wiring, EPA 608 for refrigerants, and local permit and code rules. Local jurisdictions with certified building programs may have their own requirements.

Count the days to your deadline

Informational only. Check it with the issuing board. Licensing rules, deadlines and CE requirements change, fee amounts are approximate, and this checklist can be out of date. It is not legal advice, and ClearLicensed is not affiliated with any state board. Sources for every rule are on clearlicensed.com/states/MT.

This information is here to help you plan, not to replace the board. Fee amounts are approximate and may be out of date. Deadlines and continuing education rules change too, sometimes without much notice. Always confirm with your licensing board and its official site before you rely on a date or an amount. This is not legal advice.
