TX HVAC Contractor

TDLR states that contractors who install, repair, or maintain systems related to air conditioning, refrigeration, or heating must have a TDLR license, and that ACR companies must employ an ACR contractor in each permanent location. If you contract directly with the public for that work, plan on the contractor license rather than technician registration or certification.

The Texas Department of Licensing and Regulation (TDLR) regulates the program. Its ACR pages list separate application paths for contractor licenses, technician registrations, technician certifications, and training program approvals. Start on the ACR homepage and follow the "Apply for a Contractor License" link, verifying current requirements there before you submit anything or pay a fee.

Those logistics are not stated on the TDLR ACR pages used for this guide, so we do not publish figures that could be stale. TDLR maintains an "Exam Information" page under the ACR program; treat that page, plus your candidate information bulletin, as the authoritative source for item count, time limit, passing score, and exam fee.

Expect broad coverage of air conditioning systems, heating systems, refrigeration systems, electrical components and controls, load calculations, duct design and installation practices, and Texas statutes, administrative rules, safety, and business practices. Weighting between areas is not published on the program's main page, so study every area instead of guessing at emphasis.

Retake limits, waiting periods, and retake fees are not listed on the TDLR ACR pages we used, and guessing them would be irresponsible. Check the ACR "Exam Information" page or contact TDLR at the phone numbers published on its site before scheduling. Plan to pass on the first attempt rather than budgeting on retakes.

Yes. TDLR's ACR page states that ACR companies must employ an ACR contractor in each permanent location. The requirement attaches to the business location, not just to individual job sites, so a company operating from multiple permanent locations must satisfy it at every one of them.

Yes. TDLR maintains continuing education requirements for license holders, along with an approved providers list and a provider-and-course approval process. Because specific hour counts and renewal cycles are set by rule and can change, confirm the current requirement on TDLR's Continuing Education page before you renew.

TDLR's ACR program includes an "Out of State Licensed Applicants" section and information on out-of-state and municipal licenses. Whether your existing credential counts toward Texas requirements depends on TDLR's review, so read that section and follow its instructions rather than assuming automatic reciprocity.

Build fundamentals first: the refrigeration cycle, basic electrical theory, and components. Then move to equipment-specific air conditioning and heating material. Add load calculations and duct design once the basics are solid, and save Texas statutes, rules, and business practices for the final pass, since that material is memorization-heavy and fades fastest.

Common failure modes are shallow electrical troubleshooting, shaky psychrometrics and load-estimate reasoning, and skipping the Texas statutes and rules portion because it feels unrelated to field work. Practice explaining why a system behaves as it does rather than only naming parts, and drill unit conversions until they are automatic.
