Texas is one of the few states where general liability is a licensing requirement for HVAC contractors: TDLR sets minimum liability insurance for every licensed air conditioning and refrigeration contractor and requires a certificate of insurance on file. ContractorsInsured.net (TX Lic #3305690, CA Lic #6015321) quotes HVAC GL across multiple Texas-admitted carriers at or above the TDLR minimums, with file-ready COIs issued right after binding, often the same business day.
What general liability covers for HVAC contractors in Texas
Most contractors buy general liability because a GC demands it. A Texas HVAC contractor cannot even hold the license without it. Before we get to the licensing rules, here is what the policy actually does: it responds when a third party claims bodily injury or property damage from your work, including claims that surface long after the job is closed out.
The claims carriers see most from HVAC operations:
- Carbon monoxide bodily injury from combustion or venting errors on furnaces and gas appliances, often alleged months or years after the install
- Water damage from condensate lines and drip pans failing after you leave the job (this is completed operations territory)
- Fire traced to faulty installs or electrical connections
- Refrigerant releases that damage property or trigger injury allegations
- Legal defense for covered claims, a major value driver even when the allegation is disputed
What GL does not cover for HVAC contractors
- Design and sizing errors: load calculations and duct design mistakes need professional liability / E&O, which we quote alongside GL. See professional liability
- Employee injuries: that is workers compensation, which is optional for Texas private employers but demanded by most GCs. See workers' compensation
- Your own tools and vehicles: inland marine and commercial auto handle those. See tools and equipment and commercial auto
One note for contractors who cross state lines: in California, HVAC is the C-20 classification and is one of the four classes required to carry workers compensation even with zero employees since 2023, with every classification following on January 1, 2028.

The TDLR reality: your license depends on this policy
Texas regulates air conditioning and refrigeration contracting under Texas Occupations Code Chapter 1302, and TDLR sets the insurance requirements under section 1302.102. That makes this page different from most trade insurance pages: in Texas, GL is not a nice-to-have, it is the thing standing between you and a suspended license.
Class A vs Class B: what the license classes mean
Under section 1302.253, a Class A license covers systems of any size, while a Class B license covers cooling up to 25 tons and heating up to 1.5 million BTU per hour.
The insurance minimums TDLR enforces (16 TAC section 75.40)
- Class A: at least $300,000 per occurrence (combined property damage and bodily injury), $600,000 aggregate, and $300,000 products and completed operations aggregate
- Class B: at least $100,000 per occurrence, $200,000 aggregate, and $100,000 products and completed operations
- Dual licensees: one policy meeting the Class A minimums covers both licenses
- Carrier requirement: the insurer must be authorized in Texas
Your COI is filed with TDLR, not just handed to a GC
A certificate of insurance must be filed with TDLR at initial licensure, whenever your business name changes, and on request, and TDLR has a dedicated COI form for it. Licensees must also give customers the carrier name, policy number, and agent contact on request. A lapse is not a paperwork problem, it is a license problem.
Technicians and EPA certification
Anyone assisting on ACR work must be a TDLR registered technician working under a licensed contractor. Only the contractor license, which requires the exam plus insurance, allows contracting with the public. Separately, EPA Section 608 certification is federally required for anyone handling refrigerant.
The city layer: registrations and permits
Fort Worth requires contractor registration on file to pull mechanical permits, and Dallas requires registration for permitted work. Houston generally issues mechanical permits on the TDLR license itself. Confirm local requirements before scheduling permitted jobs.
What underwriters actually rate
Beyond the license, carriers price HVAC GL on your service versus new construction mix, refrigerant and combustion work, crew size, requested limits, and subcontractor use. Disclose the real mix early so the quote survives underwriting.
What HVAC general liability costs in Texas
Published benchmarks give a useful range. Insureon reports an HVAC average of roughly $78 per month for $1M/$2M GL. NEXT reports $76 per month average for 77 percent of its HVAC customers, with a typical range of about $54 to $193. MoneyGeek's HVAC analysis runs higher at around $201 per month. Treat these as reference points, not quotes.
The drivers that move your actual price:
- Service versus new construction mix (new construction and large installs are rated differently than service and repair)
- Refrigerant and combustion work (gas furnace and venting work changes the hazard profile)
- Crew size and number of registered technicians
- Requested limits (TDLR minimums versus a $1M/$2M contract-ready program)
- Subcontractor use and how you verify sub insurance
| Package | GL limits | What it does |
|---|---|---|
| Class B minimum | $100,000 per occurrence / $200,000 aggregate / $100,000 products and completed operations | Keeps a Class B license active (cooling up to 25 tons, heating up to 1.5 million BTU per hour). Lowest premium of the three, but most commercial packets will reject it. |
| Class A minimum | $300,000 per occurrence / $600,000 aggregate / $300,000 products and completed operations aggregate | Keeps a Class A license active and covers dual licensees on one policy. Still below what most GC contracts require. |
| Contract-ready | $1M per occurrence / $2M aggregate plus AI, PNC and WOS endorsements | What commercial GCs and bid packets routinely require, and what most working HVAC contractors actually carry. Priced case by case. |

Bid and compliance requirements in Texas (COI + endorsements)
Here is the reframe that matters for Texas HVAC contractors: the TDLR minimums are floors, not targets. Commercial GCs and bid packets routinely require $1M per occurrence and $2M aggregate plus Additional Insured, Primary and Noncontributory, and Waiver of Subrogation, so most working HVAC contractors carry far more than the statute requires. We quote to the contract, not just the license.
Texas HVAC contractors typically run into GL requirements through:
- TDLR itself (the COI filed at licensure and on business name changes)
- GC bid packets and subcontract agreements on commercial and multi-family projects
- Property manager and facility vendor onboarding
- School district, hospital, and municipal maintenance contracts
What you are usually asked for
- A Certificate of Insurance (COI) showing general liability limits and effective dates
- Additional Insured (AI) for the GC, owner, or property manager
- Primary and Noncontributory (PNC) wording when the contract requires your GL to respond first
- Sometimes a Waiver of Subrogation (WOS) request (often seen on workers' comp, but occasionally requested broadly by contract language)
COI vs endorsement (the thing that breaks approvals)
A COI is proof of coverage. An endorsement is the actual policy change form. If a contract requires AI or PNC, the carrier often needs to issue the endorsement, not just type notes on the certificate. Send the contract insurance exhibit or the exact endorsement wording request, because small wording differences can cause repeated rejections in vendor portals.
No policy yet? We quote general liability the same business day, bind, and issue the certificate right after. Need a COI for TDLR or a GC portal? Send the exact certificate holder details and endorsement requirements up front. We issue your COI right after binding, often the same business day.

Common scenarios for Texas HVAC GL
Scenario 1: New Class B licensee needs a COI on file to activate the license
You passed the ACR exam and TDLR will not issue the license until a certificate of insurance is on file. Every day of waiting is a day you cannot legally contract with the public.
What to do:
- Confirm the license class so limits meet or exceed the correct minimums
- Make sure the insurer is authorized in Texas (TDLR checks)
- We bind and deliver the file-ready certificate the same day so your license is not stuck waiting
Scenario 2: Hospital bid packet wants $1M/$2M with AI, PNC and WOS
A commercial HVAC sub bidding a hospital job opens the insurance exhibit and finds requirements far above the TDLR minimum: $1M per occurrence, $2M aggregate, Additional Insured, Primary and Noncontributory, and Waiver of Subrogation.
What to do:
- Send the insurance exhibit itself, not a summary: exact wording drives which endorsements work
- We requote to the contract limits and add the endorsements before the deadline
- Keep the TDLR filing intact while the program changes (additional insured, primary and noncontributory, waiver of subrogation)
Scenario 3: Carbon monoxide claim two years after a furnace job
A service company gets a carbon monoxide bodily injury claim two years after a furnace install. The job is long closed, but the allegation ties back to combustion and venting work. This is exactly what products and completed operations coverage exists for.
What to do:
- Report the claim promptly and preserve job documentation (scope, inspection sign-offs, photos)
- Completed operations coverage is the part of GL built for post-completion claims
- This is why we treat completed ops limits as a deliberate choice, not an afterthought, when we quote
