Michigan HVAC License Verification — How to Look Up a Contractor

Why Verifying a Michigan HVAC Contractor's License Matters

Hiring an unlicensed HVAC contractor in Michigan creates real problems for homeowners and general contractors alike. If the work fails inspection, the homeowner is stuck with the code violation. If the contractor disappears, there's no licensing board to file a complaint with. And if the contractor files a construction lien for work that required a license, the homeowner may not realize the lien is unenforceable because the contractor was never licensed — a dispute that costs time and legal fees to resolve.

Michigan makes license verification straightforward through LARA's public database.

How to Use LARA's License Lookup

LARA maintains a public search tool through the Accela Citizen Access portal where anyone can verify a mechanical contractor's credentials. Here's what to check:

Search by name or license number. The portal lets you search for individual licensees (the contractor of record's name) or by business name. If the contractor gave you a license number, entering it directly is the fastest route.

What the results show:

• License status — Active, expired, suspended, or revoked. Only an "active" status means the contractor is currently authorized to work.
• Classifications held — The specific mechanical work categories (A through J) the contractor is licensed for. If they're quoting you on a refrigeration job but only hold Classification B (HVAC Equipment), they're operating outside their authorized scope.
• Expiration date — Michigan mechanical licenses renew on a triennial (3-year) cycle. A license that expired last month means the contractor can't legally pull permits until they renew.
• Disciplinary history — Any past enforcement actions, violations, or license suspensions appear in the record.

What to Look For Beyond the License

A valid LARA license is necessary but not sufficient. Before hiring a Michigan HVAC contractor, also verify:

• Local registration — The contractor should be registered with your local building department. A state license that isn't registered locally means they can't pull permits in your jurisdiction.
• Insurance — Ask for a certificate of insurance showing active commercial general liability coverage. Workers' compensation is required when Michigan's thresholds apply — for example, one or more employees regularly working 35 hours a week for 13 weeks or longer in the preceding 52 weeks, or three or more employees at one time.
• Permit history — Your local building department's portal may show the contractor's permit history, including any failed inspections or code violations on past projects.

When the Lookup Shows No Results

If a contractor claims to be licensed but doesn't appear in LARA's database, there are a few possibilities:

• They're confusing an EPA Section 608 certification with a state contractor license — the EPA credential doesn't appear in LARA's system because it's a federal environmental certification, not a state business license.
• They hold a trainee registration rather than a full contractor license. Trainees can perform work under the direct supervision of a licensed contractor, but they cannot contract independently or pull permits.
• Their license is under a business name that differs from the name they gave you. Ask for the exact license number or business entity name.

If none of these explanations apply, the contractor may be unlicensed — which means any work they perform is subject to the penalties under MCL 339.5601. For residential work that required a mechanical license, an unlicensed contractor cannot enforce a construction lien, and a lawsuit to recover for work requiring a license requires the contractor to allege and prove proper licensure under MCL 570.1114a.

For Contractors: Keeping Your Record Clean

If you're a licensed contractor, your LARA record is public-facing. Homeowners, general contractors, and competing firms can check your status at any time. Keep your license current and resolve any code violations promptly — because your record follows you through every permit application and every client who does their due diligence. LARA's current renewal guidance does not require code-update courses for a mechanical contractor license.
