HVAC Contractor Insurance in Wisconsin: Heating and Cooling Business Coverage

Insurance for Wisconsin HVAC Contractors

HVAC contractors install, repair, and maintain systems that keep Wisconsin homes and businesses comfortable through brutal winters and hot summers. This work involves electrical components, gas lines, refrigerants, and heavy equipment - all creating specific liability exposures. The right insurance program protects your HVAC business from the unique risks you face every day.

MM Insurance Associates has insured Wisconsin contractors for over 29 years. As an independent agency, we compare HVAC insurance options from multiple carriers to find you the best combination of coverage and cost.

Essential HVAC Insurance Coverage

General Liability Insurance

General liability covers property damage and bodily injury claims from your HVAC work. Common claims include damage to customer property during installation, carbon monoxide exposure from improper furnace installation, refrigerant leaks damaging property, and injuries to customers or bystanders at your work site.

Workers Compensation Insurance

HVAC technicians face hazards including electrical shock, refrigerant burns, falls from ladders, heat exposure, and injuries from heavy equipment. Wisconsin requires workers comp for employers with three or more employees. HVAC work typically falls under class code 5537 or 5538.

Commercial Auto Insurance

Your service fleet is critical to operations. Commercial auto covers your trucks and vans for liability and physical damage. If technicians use personal vehicles for service calls, hired and non-owned auto coverage fills the gap.

Additional HVAC-Specific Coverage

Pollution Liability

HVAC contractors work with refrigerants and chemicals that can cause environmental contamination. If a refrigerant release causes property damage or a cleanup is required, pollution liability covers the costs that standard general liability excludes.

Professional Liability

If your HVAC design or sizing recommendation leads to inadequate heating/cooling, mold growth, or energy waste, professional liability covers claims from design errors and professional advice.

Tools and Equipment

Recovery machines, manifold gauges, vacuum pumps, combustion analyzers, and other specialized HVAC tools need protection. Inland marine coverage protects your equipment on the road, at job sites, and in your shop.

Service Agreement / Warranty Coverage

If you offer maintenance contracts or extended warranties, you may need coverage for claims arising from these agreements, especially if a system failure causes property damage between scheduled service visits.
