How to verify a Dallas HVAC contractor license

Match four things exactly

Compare the person or contractor name, license number, company name and proposed type of work. A license belonging to someone with a similar name or an unrelated business is not enough. Ask the bidder to explain any mismatch before you pay a deposit.

TDLR also requires insurance for licensed ACR contractors. Ask for current proof that applies to the contracting entity, and contact the insurer if the project risk justifies direct confirmation.

A valid license does not replace a technical scope

Licensing is a threshold check. The proposal still needs model numbers, capacity, efficiency ratings, controls, electrical assumptions, refrigerant-line treatment, condensate disposal, duct work, commissioning and warranty terms. For replacements, ask how the proposed equipment was sized.

• Save a dated screenshot or PDF of the lookup result.
• Verify the license again if the project is delayed substantially.
• Do not accept another company’s permit or license number without explanation.
• Put registration and labor-warranty responsibilities in the closeout list.

Report suspicious claims to the regulator

If a company advertises regulated work without a verifiable license or misuses a number, preserve the ad and proposal. TDLR provides complaint and enforcement information through its ACR program.
