What insurance does an HVAC contractor need?

General liability is the baseline; most HVAC contractors add tools & equipment, commercial auto, workers' compensation, and often a business owner's policy. Reported general liability runs about $941/year, per Insureon.

Does HVAC insurance cover a system that fails after install?

Only if completed-operations is included. A system that fails months after install is a completed-operations claim, and products and completed-operations coverage must be explicitly included. Confirm it rather than assume it.

Are EPA refrigerant violations covered?

Typically not. EPA refrigerant-handling violations are usually excluded. Liability insurance is not a substitute for proper certification and handling; the fine for a violation is on you.

Do HVAC contractors need a license bond?

Many states require a contractor license bond in addition to liability insurance. The bond satisfies the licensing board; the liability policy protects against property damage and injury claims. They are separate requirements.

How much does HVAC contractor insurance cost?

Reported median general liability is about $941/year and a business owner's policy about $1,493/year, per Insureon. Those are averages, not quotes; install exposure and tool value move your number.
