What it is and who needs it.
What the mechanical bond actually guarantees
Minnesota does not issue a statewide mechanical contractor license, but under Minn. Stat. 326B.197 anyone who contracts to do gas, heating, ventilation, cooling, air conditioning, fuel-burning, or refrigeration work must give and maintain a $25,000 bond with the State, filed with the Department of Labor and Industry, Construction Codes and Licensing Division.
The bond is for the benefit of persons suffering financial loss because of the contractor's failure to comply with the State Mechanical Code. A party harmed by non-compliant mechanical work can recover against the bond, up to the $25,000 penal sum.
The DLI bond filing is generally valid for two years (a $100 filing fee at DLI, separate from the surety premium). It is not insurance for you — if the surety pays a claim, you repay the surety. Contractors who work to code treat the bond as a cost of doing business, not a risk.

Claims, renewal, filing, and what sets the price.
If a claim is made
A claim comes from the party the bond protects, the obligee named on the form, when the duty the bond guarantees is not met.
The surety investigates and pays a valid claim, up to the $25,000 bond amount. You then repay the surety: a surety bond is a guarantee of your performance, not insurance for you.
Renewal and term
The carrier issues this bond for a single two-year term; the term cannot be changed at checkout.
Renewal falls on the statutory date, October 8, in the year your term ends.
Renew before the expiry date to keep the bond in force: the license, permit or contract it backs expects continuous coverage.
How to file it
File with the Department of Labor and Industry. Your executed bond arrives by email, ready to file with DLI on the form it approves. Wet-ink original mailed on request.
What sets the price
The premium is fixed at $438 at the $25,000 amount for every applicant: the carrier’s rate book prices this bond by the form, not by your credit or your business profile.
