How do I check a hvac contractor's license in Minnesota?

Minnesota does not require a statewide hvac contractor license. Minnesota does not have a dedicated statewide HVAC license. Residential contractors performing HVAC must hold a Department of Labor and Industry residential contractor license; commercial HVAC is locally licensed.

When a state doesn't license a trade at the state level, verification leans on three things: (1) the local city or county building department's licensing or permit registry, (2) Secretary of State entity registration at Minnesota Secretary of State, and (3) the contractor's public-record history — court judgments, liens, OSHA citations, and BBB complaints.

Step 1: Check whether the city or county where the work will be performed has a local contractor license. In Minneapolis and Saint Paul, many HVAC contractors are required to register with the city building department.

Step 2: Confirm the business is registered with the Minnesota Secretary of State (https://mblsportal.sos.state.mn.us/) and that the filing status is active or in good standing. A dissolved or administratively revoked entity is a red flag — especially if the same address has a new entity registered.

Step 3: Run a free Groundcheck at earthmove.io/trust. The report pulls entity registration, court judgments, OSHA inspection history, and BBB complaints into one verdict. For unlicensed-at-state-level trades like HVAC contractors in Minnesota, the public-record history is where the trust signal lives.
