Frequently Asked Questions

How much does HVAC insurance cost in Washington?

HVAC contractor insurance in Washington typically costs $69.99 to $259.99 per month for general liability coverage. Factors affecting cost include your annual revenue, number of employees, types of systems you work on, and claims history. Commercial HVAC contractors often pay more than residential-only contractors.

What insurance does an HVAC contractor need in Washington?

Washington HVAC contractors need general liability insurance (typically $1M minimum), workers compensation through L&I for employees, commercial auto for service vehicles, and a contractor bond. Many also carry inland marine coverage for tools and equipment, plus pollution liability for refrigerant work.

Does HVAC insurance cover refrigerant leaks?

Standard general liability policies may have limited or excluded coverage for pollution including refrigerant releases. HVAC contractors who work with refrigerants should consider a pollution liability endorsement or separate policy to cover cleanup costs and third-party claims from refrigerant leaks.

Do I need separate insurance for electrical work on HVAC systems?

Your general liability policy should cover electrical work if it's part of your normal HVAC operations, but you need proper licensing. In Washington, HVAC electrical work requires an appropriate electrical license from L&I. Make sure your policy covers the full scope of work you perform.

Is HVAC installation or service work more expensive to insure?

Service and repair work is typically more expensive to insure than new construction installation. Service technicians work in occupied buildings with more third-party exposure, existing systems that can fail, and potential property damage. New construction has fewer liability risks overall.
