Minnesota HVAC technician license requirements
The answer
Minnesota has NO statewide HVAC technician or contractor license. DLI's trade licensing covers electricians, plumbers and high-pressure piping — HVAC work itself is unlicensed at the state level (cities may have their own mechanical permits/licenses, and residential contractors register with DLI). EPA 608 is federally required for refrigerant work; gas and wiring connections trigger the plumbing/electrical licenses.Your paths to the license
