What should a California contractor prepare for a business insurance review?

Prepare the business name, license or trade information, employee and payroll details, operations, vehicles or equipment when relevant, contracts, prior coverage, and claims history. A licensed team member can then review the request subject to carrier eligibility, policy terms, and underwriting.

How are business insurance limits or terms selected for a contractor?

Limits and terms are not universal. They can be influenced by the contractor's actual work, contracts, employee duties, vehicle use, project requirements, prior loss history, carrier guidelines, and applicable California requirements. The appropriate structure must be reviewed for the individual operation.

C-20 HVAC License and Insurance Requirements

Quick Answer

C-20 HVAC Contractors install, alter, and service heating, ventilation, air conditioning, and refrigeration systems in California. Required: CSLB license, WC under SB 216 (Class 5537 — pricing varies by classification, payroll, operations, claims history, limits, and underwriting/$100), $25K bond, and GL with a pollution liability endorsement (refrigerant releases are excluded by standard GL). Annual insurance: pricing varies by classification, payroll, operations, claims history, limits, and underwriting. Call (858) 925-9555.

The Refrigerant Pollution Gap

Standard GL contains a "pollution exclusion" that bars coverage for refrigerant releases — including HFC and HFO refrigerants. If a leak from a system you installed causes property damage or health claims, a basic GL policy will deny the claim. Every HVAC policy needs a pollution endorsement specifically including refrigerants.
