Why HVAC Insurance Is Specialized
HVAC contractors work with high-voltage electrical systems, natural gas and propane lines, and EPA-regulated refrigerants. That combination creates a liability profile that standard contractor GL policies may not fully address. Getting the right coverage — and the right carrier — matters.
The most expensive HVAC claims:
Carbon monoxide incidents from improper gas furnace connections (can reach $500,000+), electrical fires from faulty wiring ($50,000–$200,000), and refrigerant leaks that damage commercial HVAC systems ($20,000–$100,000). All covered by GL — if you have adequate limits.
Coverage Every HVAC Contractor Needs
General Liability
Covers property damage and injury during and after HVAC work. Completed operations included — covers failures after job is complete.
Workers' Compensation
Elevated WC rates due to electrical, refrigerant, and confined space exposure. NCCI code 5537.
Commercial Auto
Covers your service van, ladder rack, and equipment in transit. Tool theft from vehicles is the most common HVAC claim.
Inland Marine (Tools)
Covers manifold gauges, refrigerant recovery machines, vacuum pumps, leak detectors — $10,000–$30,000 in tool value for a single tech.
Professional Liability
For HVAC contractors who design systems, specify equipment, or provide energy audits — covers design errors and specification failures.
