HVAC Contractor Insurance in Texas: What You’re Required to Carry and What Actually Protects You
Texas HVAC contractors operate in one of the most insurance-specific licensing environments in the country. The Texas Department of Licensing and Regulation (TDLR) mandates minimum liability coverage as a condition of your license — and those minimums are lower than what any real job site exposure warrants. This guide covers what the state requires, what it doesn’t, and what a properly structured insurance program looks like for HVAC contractors operating in Houston and across Texas.
Key Facts for Texas HVAC Contractors
- TDLR minimum for Class A license: $300,000 per occurrence / $600,000 aggregate — file certificate directly with TDLR
- TDLR minimum for Class B license: $100,000 per occurrence / $200,000 aggregate
- What the minimums don’t cover: Workers’ comp, commercial auto, tools and equipment, or completed operations claims
- Texas workers’ comp: Not mandatory under state law for most private employers — but required by many commercial clients and government contracts
- Average GL cost for Texas HVAC: $75–$200/month depending on revenue, payroll, and claims history
Texas TDLR License Requirements: What You Must Carry
To hold an Air Conditioning and Refrigeration Contractor license in Texas, you must maintain commercial general liability insurance throughout the license period. The requirements differ by license class.
Class A license holders must carry at minimum $300,000 per occurrence combined for property damage and bodily injury, with a $600,000 aggregate limit. Class B license holders — limited to cooling systems under 25 tons and heating systems under 1.5 million BTUs/hour — must carry $100,000 per occurrence and $200,000 aggregate.
The coverage must be obtained from an insurer authorized to write liability insurance in Texas under the Texas Insurance Code. When you apply for an initial license, change your business name or affiliation, or upon TDLR request, you must file a completed certificate of insurance directly with the department. TDLR does not accept certificates submitted by email from applicants — the insurer or broker must file directly.
What these minimums don’t require: workers’ compensation, commercial auto, inland marine coverage for tools and equipment, or any form of professional liability. Those gaps create real exposure that the licensing requirement doesn’t address.
Why the State Minimums Aren’t Enough
The TDLR minimum of $300,000 per occurrence is a licensing threshold, not a risk management benchmark. A single refrigerant leak that damages a commercial tenant’s inventory, a unit installation that causes a fire two weeks after completion, or a technician who causes a slip-and-fall on a client’s property — any of these scenarios can generate claims well above $300,000 in a state where plaintiff attorneys are well-funded and juries in Harris County tend toward plaintiff-friendly verdicts.
We work with Houston HVAC contractors regularly, and the ones who’ve had significant claims consistently say the same thing: the state minimum would have been exhausted on legal defense costs alone, before any settlement. The practical minimum for any HVAC contractor doing commercial work in Houston is $1M per occurrence with a $2M aggregate — and $2M per occurrence for contractors servicing energy sector, healthcare, or government facilities.
The Full Coverage Program for Texas HVAC Contractors
General Liability
The foundation. Covers third-party bodily injury and property damage arising from your operations, including completed operations coverage — which responds to claims that arise after the job is done. Completed operations is particularly important for HVAC: installation errors, refrigerant issues, and electrical problems often manifest days or weeks after the work is finished. Make sure completed operations is included and not sublimited.
- Recommended limits: $1M per occurrence / $2M aggregate for most contractors
- $2M per occurrence for commercial, healthcare, or energy sector work
- Confirm completed operations coverage is included and at full limits
- Average cost: $100–$200/month for a solo operator; $300–$600/month for a 5-person crew with $1M revenue
Commercial Auto
If any vehicle is used for business purposes — driving to job sites, transporting equipment, carrying tools — it needs commercial auto coverage. Personal auto policies explicitly exclude business use. In Texas, a contractor whose technician gets into an accident while driving to a service call under a personal auto policy will find the claim denied. Commercial auto covers owned vehicles, and hired and non-owned auto (HNOA) covers employees using personal vehicles for work purposes.
- Required limit: $1M combined single limit for most commercial clients
- Average cost: $150–$300/month per vehicle for service vans in Houston
- Add HNOA if technicians use personal vehicles for any work-related driving
Workers’ Compensation
Texas is the only state that doesn’t require private employers to carry workers’ compensation insurance. But optional doesn’t mean unimportant. Without workers’ comp, a non-subscribing employer in Texas is exposed to common law negligence claims from injured employees — and cannot use the three standard defenses (contributory negligence, assumption of risk, fellow servant rule) that workers’ comp subscribers can invoke. A serious injury to a technician without WC coverage can generate a six-figure judgment with no coverage backstop.
More practically: virtually every general contractor, property manager, and commercial client in Houston requires proof of workers’ compensation before a subcontractor can work on their site. If your technicians service commercial buildings, hospitals, or government facilities, you need workers’ comp to win those contracts.
- HVAC technician WC rate in Texas: typically $8–$15 per $100 of payroll
- A crew of 3 technicians at $50,000/year each: ~$12,000–$22,500 in WC premium annually
- Required for most commercial, healthcare, and government contracts regardless of state law
Tools and Equipment (Inland Marine)
Your refrigerant recovery equipment, manifold gauges, vacuum pumps, diagnostic tools, and the units you’re installing before the customer accepts them — none of this is covered under a standard GL policy. An installation floater covers equipment being installed until the client accepts the completed work. A tools and equipment policy covers your gear wherever it travels.
- Installation floater: covers HVAC units and materials from leaving your warehouse to client acceptance
- Tools and equipment: covers owned gear against theft, damage, and mysterious disappearance
- Combined cost: $50–$150/month depending on total equipment value
Pollution Liability
Refrigerants are regulated substances. A refrigerant leak — whether from improper recovery, a damaged line, or a defective component — can trigger environmental liability claims. Standard GL policies contain pollution exclusions. For HVAC contractors working with refrigerants, a pollution liability endorsement or standalone policy is worth considering, particularly for commercial accounts where building management is sophisticated enough to pursue it.
Houston Market Specifics
Houston’s climate drives one of the highest HVAC service densities in the country — the combination of extreme summer heat, Gulf Coast humidity, and year-round cooling demand means Houston HVAC contractors are among the busiest in the nation. That volume also means more job site exposure, more completed operations risk, and more vehicles on the road.
Harris County is a high-litigation jurisdiction. Claims that might settle for $150,000 in a rural Texas county can reach $400,000+ in Harris County before trial. Carrying limits above the TDLR minimum isn’t just risk management — it’s the practical cost of doing business in the Houston market.
The energy sector creates specific considerations for Houston HVAC contractors. Servicing compressor stations, offshore support facilities, or energy company office buildings often comes with contractual insurance requirements of $2M GL, $2M auto, $1M employers liability, and $10M umbrella. Know your clients’ requirements before pricing a job — the insurance cost is part of your bid.
What HVAC Contractor Insurance Costs in Texas
Pricing depends primarily on annual revenue, number of employees, claims history, and the type of work you do (residential vs. commercial, new installation vs. service and repair).
- Solo operator, residential service: GL $75–$120/month; tools $30–$50/month. Total: $105–$170/month
- 3-person crew, mixed residential/commercial: GL $200–$350/month; auto $300–$500/month; WC $800–$1,500/month. Total: $1,300–$2,350/month
- 10-person operation, primarily commercial: GL $400–$700/month; auto $600–$1,000/month; WC $2,500–$4,000/month; umbrella $150–$250/month. Total: $3,650–$5,950/month

Frequently Asked Questions
What insurance do I need to get a Texas HVAC contractor license?+
To obtain a Class A HVAC contractor license in Texas, you must carry commercial general liability insurance with at least $300,000 per occurrence and $600,000 aggregate. Class B requires $100,000 per occurrence and $200,000 aggregate. The certificate must be filed directly with TDLR — you cannot submit it yourself as the applicant. Your insurer or broker must file it on your behalf, and it must come from a carrier authorized to write liability insurance in Texas.
These are the minimums to get and maintain your license. They are not the same as adequate coverage for your operations. Most commercial clients, property managers, and general contractors will require $1M per occurrence as a condition of any subcontract — which means carrying the TDLR minimum makes you unlicensable by many clients regardless of your legal license status.
Is workers’ comp required for Texas HVAC contractors?+
Not under state law — Texas is the only state that doesn’t mandate workers’ compensation for most private employers. However, most commercial building owners, general contractors, and government agencies require proof of workers’ comp before any subcontractor can work on their projects. If you service commercial buildings in Houston, you need workers’ comp to win those contracts regardless of what state law requires.
The financial risk of not carrying it is also significant. Texas non-subscribers cannot use three standard legal defenses against employee injury claims, which meaningfully increases their exposure. A technician seriously injured on a job site can generate a substantial judgment that your GL policy won’t cover — GL covers third-party claims, not employee injuries.
Does my HVAC contractor insurance cover refrigerant leaks?+
Not under a standard GL policy — refrigerants are regulated substances and standard GL policies contain pollution exclusions that can apply to refrigerant releases. Whether a specific refrigerant release triggers the pollution exclusion depends on the exact policy language and the circumstances of the release. Carriers have taken both positions on this depending on the facts.
HVAC contractors who regularly work with refrigerants should either confirm their GL policy has a contractor’s pollution liability (CPL) endorsement that covers refrigerant releases, or purchase a standalone pollution liability policy. The cost is modest relative to the exposure — refrigerant contamination claims in commercial buildings can reach six figures quickly.
How do I add a general contractor as additional insured in Texas?+
Contact your insurance broker with the GC’s full legal entity name and the project or contract details. The broker will request an additional insured endorsement from your carrier — typically the CG 20 10 (ongoing operations) and CG 20 37 (completed operations) endorsements. This costs $20–$50 per client annually in most cases. Your broker then issues an updated certificate of insurance reflecting the additional insured status.
Don’t just note it on the certificate without a policy endorsement — the certificate without the endorsement is not binding. GCs and property managers are increasingly sophisticated about verifying actual endorsement documentation rather than accepting COI notation alone. Get the endorsement issued and have your broker send documentation to the GC directly.
What is an installation floater and do HVAC contractors need it?+
An installation floater covers equipment, materials, and property you’re installing — from the time it leaves your possession to when the client formally accepts the completed work. For HVAC contractors, this means the units, ductwork, and components you’re responsible for during a job are covered if they’re damaged, stolen, or destroyed before the client signs off.
Without an installation floater, a condensing unit stolen from a job site overnight is likely not covered by GL (which covers third-party claims, not your property) and not covered by property insurance (which covers property at your business location, not at a job site). Installation floaters are relatively inexpensive — $50–$150/month for most HVAC contractors — and fill a real gap that standard policies miss.
