Texas HVAC license, estimate, permit, and inspection guide

Step 1: verify the Texas record

Search the official TDLR system for the person or the business. Write down the name, license type and number, status, expiration, and anything else tied to the contracting party. If the proposal uses a different company name or address, ask for the documented relationship before you sign. A current license is an eligibility check, not proof the proposal itself is any good.

Match every name before you rely on the license

Write the advertised company name, legal contracting entity, proposal signer, TDLR-listed business or responsible license, payment recipient, and warranty provider on separate lines. They may legitimately differ, but the relationship should be explained in writing. A license number in an ad or footer is not enough if you cannot connect it to the business taking your money and accepting responsibility for the work.

Step 2: make the estimate auditable

A written estimate should name the legal seller, the scope, and the exact equipment or repair. It should list included and excluded work, who handles permits, the price and financing terms, the deposit, the schedule, warranties, the change-order rule, cancellation terms, and who's authorized to sign. Keep marketing promises out of your decision unless they're written into the contract.

Step 3: verify the local permit path

Use the city, or other authority having jurisdiction, for your address and exact scope. Dallas routes residential permitting through city resources and DallasNow. Fort Worth says work that changes or repairs mechanical systems can require permits, and it provides online permit and inspection links. Rules, forms, fees, and exemptions change, so verify on your decision date.

Ask five permit questions before work begins

Confirm whether the exact scope requires a permit, who applies, whose license appears on the application, whether the fee is included, and who schedules and corrects the inspection. Ask for the permit number once issued. If a bidder says no permit is required, record who at the authority having jurisdiction confirmed that for your address and scope, plus the date. This turns a verbal assumption into something you can revisit.

Step 4: close the record after work

Keep the final contract and change orders, the paid invoice, the permit number and inspection result where required, the installed model and serial numbers, the AHRI certificate for a replacement, your registered warranties, the startup or commissioning (startup testing) readings, and the operating instructions. Ask who fixes a failed inspection, and whether that work changes the price.

Do not make final payment against an unfinished record

Before final payment, compare the installed model and serial numbers with the contract, save the AHRI certificate, confirm startup results and control setup, collect registration confirmations, and obtain the permit and final inspection result where required. Resolve open corrections, damage, cleanup, change orders, and exclusions in writing. The purpose is not to hold up a finished job, it is to make sure the job and the documents close together.
