Licensed HVAC Contractor in Texas: How to Verify Before You Hire

Hiring an HVAC contractor in Texas means trusting someone with your home's heating, cooling, and sometimes gas lines. A mistake here isn't just expensive — it can be dangerous. Before you sign anything, knowing how Texas licenses HVAC contractors and how to verify that license takes about two minutes and can save you thousands.

Does Texas require a license for HVAC contractors?

Yes. Texas requires HVAC contractors to hold an Air Conditioning and Refrigeration Contractor (ACR) license issued by the Texas Department of Licensing and Regulation (TDLR). This is a statewide requirement that applies to anyone installing, maintaining, or repairing HVAC systems for compensation in Texas.

The ACR license has two main classes: Class A covers all types and sizes of systems, while Class B is limited to systems under 25 tons. Technicians working under a licensed contractor must hold a separate HVAC technician registration. If a company sends an unlicensed tech to your home, the contractor is violating state law.

How do you verify an HVAC license in Texas?

You can look up any HVAC license directly through the TDLR license search at tdlr.texas.gov. Enter the contractor's name, business name, or license number and you'll see their license status, classification, expiration date, and any disciplinary actions on record.

Always check the expiration date. An expired license is the same as no license in the eyes of Texas law. Also look for any complaint history or enforcement actions — TDLR publishes these publicly, and a pattern of violations is a serious red flag.

If the contractor can't provide a license number or their name doesn't appear in the TDLR database, stop there. Do not proceed with the hire.

What bond and insurance does a Texas HVAC contractor need?

Texas HVAC contractors licensed by TDLR are not required to carry a surety bond as a condition of licensure at the state level. However, they are required to carry liability insurance. Many municipalities and commercial clients have their own bonding and insurance minimums on top of state requirements.

Before hiring, ask for a certificate of insurance naming you as an additional insured. Verify the policy is current by calling the insurer directly — certificates can be forged. Minimum general liability coverage of $300,000 is common in residential HVAC work, but higher is better for larger projects.

What happens if you hire an unlicensed HVAC contractor in Texas?

Hiring an unlicensed HVAC contractor in Texas exposes you to serious financial and safety risk. If an unlicensed contractor installs a system incorrectly and causes a fire, gas leak, or carbon monoxide issue, your homeowner's insurance may deny the claim because the work was not performed by a licensed professional.

You also lose all legal protections. A licensed contractor in Texas can be reported to TDLR, which can revoke their license, levy fines, and order corrective work. With an unlicensed contractor, your only recourse is civil court — and if they've skipped town, you're left with nothing.

TDLR received over 3,000 complaints against HVAC and related contractors in a recent year. The most common issue: unlicensed work. These aren't edge cases — they're routine.

What should you ask an HVAC contractor before hiring in Texas?

Before signing a contract, ask for the contractor's TDLR license number, proof of current liability insurance, and the name of the licensed technician who will perform the work. All three should be easy for a legitimate contractor to provide on the spot.

Also ask whether the work requires a permit. In Texas, most HVAC installations and replacements require a local permit. The contractor should pull the permit — not you. If they suggest you pull it yourself or skip it entirely, that's a major warning sign.

A permit creates an inspection record that protects you when you sell the home. Missing permits can delay or kill a real estate transaction and trigger expensive corrective work.

How much does a licensed HVAC contractor cost in Texas?

Licensed HVAC contractors in Texas typically charge $75 to $150 per hour for labor, with full system replacements ranging from $5,000 to $12,000 depending on system size and home square footage. These numbers reflect licensed, insured professionals pulling proper permits.

Unlicensed contractors often quote 20-40% less. That gap disappears quickly when a failed inspection requires tearing out and redoing the work — at your expense. The cheapest bid from an unlicensed contractor is frequently the most expensive option in the end.
