HVAC Insurance
HVAC Contractor Insurance in Texas
HVAC contractors straddle two very different risk profiles: residential service-and-repair work and commercial mechanical installation. The first carries small, frequent claims; the second carries large refrigerant releases, gas-line defects, and completed-operations exposures. Texas heat compounds the danger — technicians work in 140-degree attics in August, and heat illness is a top workers' comp claim. This page explains what Texas HVAC contractors need, the refrigerant and licensing requirements, and what commercial GCs verify on a COI.
The Exposures That Define HVAC Work
HVAC involves pressurized systems, electrical connections, refrigerants, and gas lines. A refrigerant leak or a misconnected gas line can cause property damage and bodily injury far beyond the job site, and a brazed line-set joint that leaks six months after install is a completed-operations claim. Commercial mechanical work with large refrigerant charges adds pollution exposure. The insurance that protects an HVAC business has to anticipate both the small service-call claims and the large commercial defect claims.
General Liability for HVAC Contractors
HVAC GL starts at $1M per occurrence and $2M aggregate; commercial mechanical work often requires $2M per occurrence. Completed operations is critical because refrigerant and gas-line defects surface after commissioning. Verify the policy covers the HVAC class codes you actually perform, includes products and completed operations, and does not cap completed operations with a short sunset. A generic contractor policy that excludes HVAC class codes or gas-line work will not pay the claim that defines the trade.
Refrigerant and Pollution Liability
Standard GL excludes most pollution and contaminant releases, and a large refrigerant discharge on a commercial system can trigger cleanup costs the GL will not pay. For contractors handling commercial refrigeration, chillers, or phased-out refrigerants, a separate pollution liability policy or an HVAC GL endorsement with limited pollution coverage is essential. Residential service with small refrigerant charges usually does not require separate pollution coverage, but verify the policy does not exclude the chemical class code you handle.
Workers' Comp for HVAC Crews
HVAC technicians work in the most dangerous environments a Texas service trade sees: 140-degree attics, slippery rooftops, and live mechanical rooms. Heat illness, electrical shock, and fall injuries are the top claims, and a single heat-illness event can be a six-figure claim. Texas does not require workers' comp for private employers, but commercial GCs require it before an HVAC sub mobilizes. Documented hydration, acclimatization, and buddy-check programs reduce both injuries and the experience modifier.
TDLR ACR Licensing and EPA 608
The Texas Department of Licensing and Regulation issues the Air Conditioning and Refrigeration (ACR) Contractor license, required to advertise, bid, or perform HVAC work in Texas. Federal law also requires EPA Section 608 certification for anyone handling refrigerant. Unlicensed HVAC work or uncertified refrigerant handling is an uninsurable claim — carriers deny claims arising from work performed without required certification. Most Texas cities require a mechanical permit and proof of GL insurance before issuing the permit.
What GCs Require from an HVAC Sub
- General Liability at $1M/$2M minimum (commercial mechanical: $2M/$2M)
- Additional Insured via CG 20 10 and CG 20 37 (completed operations for refrigerant and gas-line defects)
- Waiver of subrogation and primary/non-contributory wording
- Refrigerant/pollution coverage for commercial refrigeration with large charges
- Workers' comp with employer liability and waiver of subrogation
- Certificate delivered before mobilization
Frequently Asked Questions
Does HVAC general liability cover refrigerant releases?
Standard GL excludes most pollution and contaminant releases. A large refrigerant discharge on a commercial system can trigger cleanup costs the GL will not pay. For commercial refrigeration, chillers, or phased-out refrigerants, a separate pollution liability policy or an HVAC GL endorsement with limited pollution coverage is required.
Why do HVAC contractors need completed-operations coverage?
A refrigerant leak or a failed gas-line connection discovered after commissioning is a completed-operations claim. CG 20 37 extends additional-insured status to those claims so the GC is protected after the HVAC sub leaves. Many Texas commercial contracts now require both CG 20 10 and CG 20 37.
Does a residential HVAC service shop need workers' comp?
Texas does not require it, but heat-illness and fall claims in residential service are severe and frequent, and operating without workers' comp puts the owner's personal assets behind every attic injury. Homebuilders and property-management companies also increasingly require HVAC service contractors to carry workers' comp and name them additional insured.
What licenses does a Texas HVAC contractor need?
The TDLR Air Conditioning and Refrigeration Contractor license is required to perform HVAC work in Texas, and EPA Section 608 certification is required for anyone handling refrigerant. Most cities also require a mechanical permit and proof of GL insurance before issuing the permit.
