Minnesota plumbing and electrical contractors are licensed by the Department of Labor & Industry (DLI). HVAC, uniquely, has no statewide license — but mechanical contractors must still file a $25,000 bond with DLI before performing work anywhere in the state.
Minnesota's $25,000 mechanical-contractor bond requirement is one of the most unusual structures in the country: you don't get a license, but you can't legally operate without filing the bond. This catches HVAC contractors moving in from neighboring states by surprise — they assume "no license" means "no compliance."
