Short version: HVAC contractors typically pay $900–$1,600/year for GL insurance
and $100–$400/year for a surety bond. Both are required for most state HVAC licenses. Bind online

HVAC surety bond
Most states require a surety bond to obtain an HVAC contractor's license. The bond protects your clients and the state licensing board if you fail to complete work, violate codes, or don't pay subcontractors. It is separate from your GL policy — one does not replace the other.

Frequently asked questions
How much does HVAC insurance cost?
General liability for an HVAC contractor typically runs $900–$1,600/year for $1M/$2M limits. Rates vary by state, annual revenue, crew size, and type of work (residential vs. commercial). HVAC carries moderate-to-high liability because refrigerant work, electrical connections, and carbon monoxide risks can lead to significant claims.
What insurance does an HVAC contractor need?
Most HVAC contractors need: GL insurance (required for licensing and commercial work), a surety bond (required for most state HVAC licenses), workers' compensation if you have employees, commercial auto for your service vehicles, and inland marine for tools and equipment. Some states also require EPA Section 608 certification to handle refrigerants.
Does an HVAC contractor need a surety bond?
In most states, yes. An HVAC contractor license requires a surety bond on file with the state licensing board. Bond amounts typically range from $5,000–$25,000; annual premiums run $100–$400 depending on bond amount and your credit score.
What does GL cover for HVAC contractors?
GL covers property damage and bodily injury caused by your work — for example, a refrigerant leak that damages equipment, a carbon monoxide issue from an improper installation, or a client tripping over your equipment. It covers legal defense costs even if the claim is unfounded.
Does HVAC insurance cover refrigerant?
GL covers damage caused by refrigerant leaks or improper handling. It does not cover the cost of the refrigerant itself or the equipment you use. Inland marine (tools and equipment coverage) covers your gauges, recovery machines, and other equipment if they're stolen or damaged.
