Minnesota HVAC & Appliance Repair Insurance Requirements (2026)

HVAC Contractors

Mechanical (HVAC) Contractor Bond Registration

Minnesota Department of Labor and Industry (DLI), Construction Codes and Licensing Division
Surety BondRequired

Minimums: $25,000 corporate surety bond

Any business contracting to do gas piping, heating, ventilation, cooling, air conditioning, fuel-burning, or refrigeration work in Minnesota must file and maintain a $25,000 surety bond with DLI (biennial $100 filing fee) instead of holding a discrete state HVAC license.[1][2]

Workers' CompensationRequired

A certificate of compliance showing Minnesota workers' compensation coverage (or an approved exemption) must be filed with DLI alongside the mechanical contractor bond.[1]

General LiabilityNot Required

Minnesota does not set a statewide general liability insurance minimum tied to the mechanical contractor bond filing itself; mechanical contractors must also comply with any separate local city licensing requirements, which may impose their own insurance rules.[1]

Residential Building Contractor (BC) / Residential Remodeler (CR) License — general residential construction/remodeling (not required for businesses that only perform standalone HVAC/mechanical work, which instead use the Mechanical Contractor Bond above)

Minnesota Department of Labor and Industry (DLI), Construction Codes and Licensing Division
General LiabilityRequired

Minimums: $100,000 per occurrence / $300,000 aggregate for bodily injury, plus $25,000 property damage (or a single combined limit of $300,000 per occurrence / $300,000 aggregate)

Licensed residential building contractors and remodelers must maintain commercial general liability insurance meeting DLI's minimum per-occurrence, aggregate, and property-damage limits.[1]

Surety BondConditional

Minimums: $40,000

Condition: only required after a Contractor Recovery Fund payout tied to the licensee

Minnesota's Contractor Recovery Fund (funded by license fees) generally replaces an individual bonding requirement, except that a licensee must post a $40,000 surety bond before reinstatement after the recovery fund has paid a claim against them.[1]

Workers' CompensationRequired

License applications must include a Minnesota workers' compensation insurance certificate (or proof of an approved exemption).[1]

Appliance Repair

No state license or insurance requirement for appliance repair. Manufacturers' warranty networks, home warranty companies, and commercial landlords typically require proof of general liability insurance (COI). Note: if a business's work crosses into gas, heating, ventilation, cooling, air conditioning, fuel-burning, or refrigeration contracting (e.g., furnace or central AC system work) rather than repair of standalone household appliances, Minnesota's $25,000 mechanical contractor bond (Minn. Stat. 326B.197) may apply — see the HVAC section.

Workers' Compensation Threshold

Minnesota has no minimum employee-count threshold: under Minn. Stat. 176.181, subd. 2, every employer liable under the workers' compensation chapter must insure payment of compensation (or obtain state-approved self-insurance) from the first employee, including a single part-time employee.
