HVAC Certification Requirement in Minnesota

While there is no state license requirement for mechanical contractors, they are required to file a $25,000 mechanical contractor bond with DLI in order to contract to perform gas, heating, ventilation, cooling, air conditioning, fuel burning or refrigeration work in Minnesota. The bond must be on a form approved by DLI and written by a surety company licensed to do business in Minnesota.

Once a mechanical contractor has properly filed their bond with DLI, they must check with the municipalities in which they intend to work to make sure that they comply with any local licensing, insurance, permitting and inspection requirements. Although mechanical contractors are not licensed by the state, they are subject to local licensing requirements.

Note: Federal law requires EPA certification.
