How to Start an HVAC Business in Texas (2026)

Texas is one of the friendliest states in the country to launch an HVAC business, and the reason is structural. Licensing runs through a single state agency, the Texas Department of Licensing and Regulation, so there is no patchwork of county boards to satisfy. Workers' comp is optional. There is no statewide contractor bond. But "friendly" does not mean "no rules." You still need a TDLR ACR contractor license, real documented experience, general liability insurance at state minimums, and EPA 608 certification before you touch refrigerant. Here is the exact sequence for 2026.

You need a TDLR ACR contractor license

Every HVAC contractor in Texas works under an Air Conditioning and Refrigeration (ACR) Contractor License issued by TDLR. This is a state license, which is the big advantage over places like California where you also juggle local requirements. One agency, one license, statewide scope. If you want the license mechanics on their own, our Texas HVAC license requirements guide breaks down the classes, fees, and exam step by step.

TDLR issues the license in two classes, and you pick based on the size of the systems you plan to work on:

| License class | Scope of work | Best for | |---|---|---| | Class A (Unlimited) | Any size cooling or heating system | Full residential and commercial, large tonnage | | Class B (Limited) | Up to 25 tons cooling and 1.5 million BTU/hr heating | Residential and light commercial |

Both classes share the same experience and exam requirements. The only differences are the capacity limits and the insurance minimums. If you are launching a residential service and replacement business, Class B is plenty and cheaper to insure. Go Class A only if you intend to chase large commercial jobs.

The 4-year experience requirement

The ACR contractor license goes to a person, not a business, and that person has to prove real time in the trade. Texas gives you two paths:

• Standard path: at least 48 months (4 years) of practical ACR experience under a licensed ACR contractor, earned within the past 72 months (6 years).
• Technician path: hold a TDLR ACR technician certification for at least 12 months, plus 36 months of supervised experience within the past 48 months.

Either way, you document the hours on TDLR's Experience Verification Form, signed by the licensed contractors who supervised you. Track your dates, employers, and duties as you go. Reconstructing four years of job history from memory the week you apply is how applications stall.

This is also the point where a non-technician owner has to make a decision. If you have never turned a wrench, you cannot qualify the license yourself. You partner with or hire someone who holds an ACR contractor license to serve as the licensed individual for the business. The mechanics of that arrangement, including what it costs and how to structure it safely, are the same across states, and we cover them in how to start an HVAC business without being a technician.

Apply to TDLR and pass the exam

Once your experience is documented, the licensing steps are straightforward:

1. File the application. Submit the Air Conditioning and Refrigeration Contractor License Application (form ACR-LIC-002) with your Experience Verification Form attached. The application fee is $115.
2. Get approved to test. TDLR reviews the application and, if it checks out, authorizes you to schedule the exam.
3. Pass the ACR contractor exam. The exam is administered by PSI and covers trade knowledge, codes, safety, and business-law topics. Budget roughly $60 to $80 per sitting. You must have an approved application on file before you can schedule.

After you pass, TDLR requires proof of insurance before it issues the license. That is the next step, and it is where Texas gets specific.

Insurance minimums (this is what TDLR checks)

Texas does not require a statewide bond, but it absolutely requires commercial general liability insurance, continuously, for as long as your license is active. A lapse in coverage can trigger automatic license suspension. The minimums scale with your license class:

| License class | Per occurrence | Aggregate | Products and completed operations | |---|---|---|---| | Class A | $300,000 | $600,000 | $300,000 | | Class B | $100,000 | $200,000 | $100,000 |

Your insurer issues a Certificate of Insurance listing your name and business name exactly as they appear on your TDLR application, and you submit it after passing the exam. TDLR will not issue the license without it.

Treat the TDLR minimums as a floor, not a target. Most commercial clients, property managers, and general contractors want to see $1 million per occurrence and $2 million aggregate before they will put you on a job. Buying to that level up front costs a Class B shop somewhere in the range of $1,500 to $3,500 a year and saves you re-shopping the policy the first time a commercial customer asks for a COI.

Workers' comp is optional in Texas (but read this first)

Texas is the rare state where workers' compensation is not mandatory. You can operate as a non-subscriber, which many small HVAC shops do to save money. But there are two catches worth understanding before you skip it.

First, non-subscribers must formally file form DWC-005 with the Texas Division of Workers' Compensation. It is not a "do nothing" option. Second, opting out strips away the legal protections the workers' comp system gives an employer. A single injured-tech lawsuit can cost far more than years of premiums. If you plan to hire even one W-2 employee or bid public and commercial work, price a policy. HVAC class codes typically run 5 to 9 percent of payroll.

This is the opposite of California, where 2026 rules force even zero-employee HVAC licensees to carry a policy. If you are comparing the two states, the California HVAC startup guide lays out how much heavier that compliance load runs.

EPA 608 and technician registration

Two more items sit outside the TDLR contractor license but gate real work:

• EPA Section 608 certification is federal and required for anyone who handles regulated refrigerant. For residential and commercial HVAC, get the Universal level. The exam runs $25 to $80, and the certification is lifetime, not renewed annually.
• ACR technician registration applies to every unlicensed tech working under your contractor license. Each one registers with TDLR at roughly $100 total in application and registration fees, and you as the license holder are responsible for supervising their work.

Set up the business itself

The license makes you legal to do the work. You still need a legal entity to run the money through:

• Form your LLC. File a Certificate of Formation (form 205) with the Texas Secretary of State for a $300 fee. Online filings typically process in 2 to 3 business days. A single-member LLC is the most common structure for a Texas HVAC startup and keeps your personal assets separate from the business.
• Get an EIN from the IRS. It is free and takes minutes online.
• Register for state tax. Apply for a Sales and Use Tax Permit with the Texas Comptroller if you sell equipment, parts, or taxable services. The permit is free, and it usually issues in 2 to 3 weeks. Talk to a Texas CPA about franchise tax thresholds for your entity.
• Check your city. TDLR is statewide, but Houston, Dallas, San Antonio, and other municipalities may require local registration or a small license or service bond on top of the state license. Confirm your city's rules before you pull your first permit.

What it costs to launch

Licensing is the cheap part. The real money is in the truck, tools, inventory, and insurance. Grounded 2026 ranges for a Texas launch:

• Lean solo (you already own a truck and tools): $8,000 to $20,000
• Typical solo (used van, new equipment): $20,000 to $30,000
• Multi-truck buildout: $30,000 to $80,000+

Inside that, the license and compliance line items are small: $115 to TDLR, $60 to $80 for the PSI exam, $25 to $80 for EPA 608, and $300 for the LLC. The rest is a used service van ($10,000 to $30,000), trade tools ($3,000 to $8,000), starter parts inventory ($1,000 to $5,000), insurance, and marketing. Because your pricing has to cover all of it plus a real margin, nail your job costing before you bid the first install. Our HVAC pricing strategies guide and the free job pricing calculator walk through the math.

Run the operations side from day one

Texas keeps the regulatory load light, which is exactly why the operators who win here compete on execution instead of paperwork. The bottleneck for a growing Texas shop is not the license. It is the first hot week of summer when the phone rings 40 times, two calls collide on the same slot, and the invoices from last week are still sitting in the truck.

Fieldtics gives you the backbone to handle that from day one. The free tier covers unlimited clients, job scheduling, a customer CRM, and a mobile app your techs will actually use, with no credit card required. The $29 per month Professional plan adds invoicing, online payments, quotes and estimates, team scheduling, and expense tracking when you are ready to grow. Fieldtics customers see 35% fewer missed appointments and recover $3,000 to $5,000 in monthly revenue that used to slip through the cracks. If scheduling jobs and crews is your first real headache, start with purpose-built HVAC scheduling software.

The bottom line

Texas rewards operators who move fast. Document your 48 months of experience, file the ACR-LIC-002 with its $115 fee, pass the PSI exam, and carry general liability at your class minimum (or better, at $1M/$2M for commercial work). Decide deliberately on workers' comp instead of skipping it by accident, lock EPA 608 before you handle refrigerant, and stand up your LLC and tax accounts. Then build the operational system so the busy season does not bury you.

Frequently asked questions

What license do you need to start an HVAC business in Texas?

A TDLR Air Conditioning and Refrigeration (ACR) Contractor License, either Class A (unlimited capacity) or Class B (up to 25 tons cooling and 1.5 million BTU/hr heating). The Texas Department of Licensing and Regulation issues it statewide, so there is no separate county or city HVAC license to earn, though some municipalities require local registration or a bond.

How much experience do you need for a Texas ACR contractor license?

The standard path is 48 months of practical ACR experience under a licensed contractor within the past 72 months. The technician path is shorter: hold a TDLR ACR technician certification for at least 12 months, plus 36 months of supervised experience within the past 48 months. A supervising contractor signs your Experience Verification Form either way.

Does Texas require workers' compensation for HVAC businesses?

No. Texas is one of the only states where workers' comp is optional. You can operate as a non-subscriber, but you must file form DWC-005 with the Division of Workers' Compensation and you lose the liability protections the system provides. Many HVAC owners still carry a policy because commercial clients and lenders ask for it.

How much does it cost to start an HVAC business in Texas?

A lean solo launch where you already own a truck and tools runs roughly $8,000 to $20,000. A typical solo start with a used van and new equipment lands around $20,000 to $30,000. The TDLR license itself is inexpensive: a $115 application, a $60 to $80 PSI exam, plus general liability insurance and an LLC filing.
