Insurance for HVAC Contractors in Washington

HVAC contractors in Washington keep homes and businesses comfortable through the state’s chilly winters and mild summers. But servicing heating, ventilation, and air conditioning systems involves technical work, job site hazards, and customer interactions—all of which come with potential liability. That’s why having the right insurance and bonds is critical for protecting your business and maintaining compliance.


General liability insurance is the foundation of protection for HVAC professionals. It covers third-party injuries and property damage, such as if a technician damages a client’s wall during installation or a customer trips over equipment. In Washington, where customer service and safety are key to reputation, this coverage helps you avoid major out-of-pocket costs.



Workers’ compensation insurance is required if you have employees, and it covers job-related injuries and illnesses. HVAC work often involves working in tight spaces, on ladders, or with hazardous materials—making this coverage essential for both legal compliance and team protection.


Tools and equipment insurance (also known as inland marine insurance) helps protect the valuable gear HVAC contractors rely on. From refrigerant gauges and vacuums to service vehicles packed with parts, this policy ensures your business doesn’t grind to a halt if equipment is stolen or damaged.

A commercial auto policy is vital for HVAC companies using vans or trucks to travel to job sites. It protects vehicles, drivers, and transported tools from accidents, theft, or weather damage. If your team uses personal vehicles for business tasks, hired and non-owned auto insurance can also be added.


In Washington, HVAC contractors must be licensed and bonded. A contractor bond guarantees that you’ll fulfill your contract obligations and follow state and local regulations. It offers peace of mind to your clients and is required to maintain a valid license with the Washington State Department of Labor & Industries.

Errors and omissions insurance, or professional liability coverage, may be worth considering for contractors offering energy efficiency audits, HVAC system design, or complex installations. It protects your business from claims of faulty recommendations or incomplete work.
