Texas A/C Contractor license lookup — free

An A/C Contractor license is the business-level credential an HVAC company needs to legally contract air conditioning and heating jobs in Texas — separate from the individual technician licenses its crew carries. TDLR is explicit that a business may not engage in air conditioning and refrigeration contracting once this license has expired, which makes it one of the few license types on this site where the state spells out the consequence in plain language rather than leaving it implied. Property owners and GCs vetting an HVAC company check this number specifically to confirm the business itself, not just the tech showing up, is authorized. A company running jobs on a lapsed contractor license risks more than a fine — it risks every permit tied to that license number.

The license renews every year, and contractors carry the program's only continuing education requirement: 8 hours annually, including at least 1 hour on Texas law and rules. A renewal filed within 90 days of expiration costs $97.50 against a $65 base fee, and anywhere from 90 days to 18 months late it climbs to $130. From 18 months to three years expired, that $130 rate still applies but only through a mailed Executive Director approval request rather than the online system; past three years, the contractor has to apply fresh rather than renew. TDLR's ACR enforcement schedule backs this up with real teeth — contracting on an expired license is a Class B violation carrying a $1,000-$3,500 fine and/or up to a year-long suspension.
