HVAC State License Guide
HVAC License Requirements in Michigan
Michigan regulates certain mechanical work at the state level, and licensing requirements can vary depending on the type of HVAC work and the scope of jobs you take on. If you install, service, or alter mechanical systems, you’ll typically need to confirm the correct mechanical licensing category and any local permitting rules. Always verify the latest requirements with the state and the local jurisdiction where the work will be performed.
Important Things to Know
- Confirm state mechanical licensing category that matches your scope of work.
- Check local permitting or registration rules for the city or county where jobs occur.
Common HVAC Certifications Contractors Often Track

Why Renewal Tracking Matters
