Contractor insurance

HVAC and mechanical contractor insurance

HVAC work combines open flame, fuel gas and equipment people depend on in a Minnesota winter. The exposures that matter most are hot work, combustion safety and what happens when an installation fails during the coldest week of the year.

What the work usually involves

Residential service, new construction and commercial mechanical work carry different exposures, and after-hours emergency work adds another layer.

  • Furnace, boiler and heat pump installation and replacement
  • Air conditioning installation and service
  • Ductwork fabrication, installation and sealing
  • Refrigerant handling, recovery and charging
  • Gas piping and appliance connection
  • Rooftop units and commercial mechanical work
  • Maintenance agreements and after-hours emergency service

Risks worth talking through

Torch and brazing work

Open flame inside a finished building is the highest-severity routine activity in this trade. Fires that start behind a wall or in a joist bay may not be discovered until after the crew has left, and the resulting claim is a structure fire rather than a service call.

Combustion and carbon monoxide

Venting, combustion air and appliance setup carry consequences that are potentially fatal rather than merely expensive. This exposure follows the completed work and can surface long after installation.

Installations that fail in the cold

A heating failure in a Minnesota January can mean frozen and burst pipes and a water loss throughout a building. The damage is often far larger than the equipment involved.

Stocked service vehicles

A fully stocked van holds significant inventory and tools, and it is parked overnight in a driveway or a lot. Vehicle break-ins and total loss of contents are common.

Rooftop and height work

Commercial units put crews on roofs, sometimes in poor weather, with equipment moved by crane or lift.

Refrigerant handling

Recovery, charging and disposal carry regulatory obligations and a potential release exposure that interacts with pollution wording in a liability policy.

Coverage areas to review

General liability

General liability may help address claims alleging bodily injury or damage to someone else's property arising from your operations. Coverage depends on the policy terms and exclusions. If you perform hot work, expect specific questions about your procedures, and possibly specific policy conditions.

Workers compensation

If you have employees, burns, falls from roofs and ladders, lifting heavy equipment and electrical contact are the main exposures. After-hours and emergency work is worth mentioning, since fatigue and poor conditions change the picture.

Commercial auto

Service vans and installation trucks, often a large part of the fleet relative to the size of the business. Who drives, whether technicians take vehicles home, and what is stocked inside are all relevant.

Tools, van inventory and equipment awaiting installation

Recovery machines, gauges, torches, vacuum pumps and sheet metal tooling represent real value, and most of it lives in a vehicle. Separately, equipment purchased for a job and staged at a site before installation is commonly handled by an installation floater rather than by your liability policy.

This page is general information, not legal, safety or coverage advice. What a policy actually covers depends on your business operations and on the policy, carrier, terms, conditions, limits and exclusions that apply. Nothing here confirms eligibility or guarantees that any coverage is available to you.

What to have ready for a review

  • Approximate split between residential service, new construction and commercial
  • Whether you perform hot work, and your procedure for it
  • Whether you perform gas piping and combustion appliance setup
  • Whether crews work on rooftops, and at what height
  • Number of service vehicles and typical inventory value in each
  • Whether you offer after-hours emergency service
  • Employee count and payroll
  • Any claims or incidents from the last several years

Questions we hear

Why do carriers ask so many questions about torch work?

Because it is the single activity most likely to turn a routine job into a total loss of a building. A fire that smoulders in a joist bay and is discovered hours later produces a claim many times the size of the work order. Having a written hot work procedure genuinely helps in this conversation.

A furnace we installed failed and pipes froze and burst. Is that a covered claim?

It is exactly the kind of completed work question worth reviewing in advance. Policies commonly distinguish between the cost of correcting your own work and the damage that failure causes to the rest of the building. In a Minnesota winter the second number is usually the large one.

Are the tools and parts in my vans covered?

Not automatically by the auto policy in the way people assume. Contents of a vehicle are usually handled as equipment or inventory rather than as part of the vehicle itself, and a stocked van can represent a serious amount of money. It is worth confirming the limit is realistic.
