Texas A/C Technician license lookup — free

TDLR actually licenses two ranks of air conditioning technician under one 'A/C Technician' banner: Registered, the entry-level tier for techs working under a licensed contractor, and Certified, an advanced tier that requires roughly 2,000 hours of additional training and experience and allows more independent work. Either way, this is the license the person actually wiring up or servicing a unit on-site is required to hold — separate from the A/C Contractor license the business itself carries. Homeowners and GCs checking a technician's number want to know the tech standing in front of them is legitimately authorized to touch their HVAC system. Because the two tiers share a renewal system, it's easy to assume they're identical, but the fees and paths differ.

Both tiers renew every year. TDLR's technician renewal and continuing-education pages don't list an hours-based CE requirement for either Registered or Certified technicians — the agency's CE page only spells out a requirement for A/C Contractors, so there doesn't appear to be one for technicians, though that's read from what's absent rather than a direct 'no CE' statement. Registered techs renew for $20 a year and Certified techs for $35, and both scale the same way if renewal slips: 1.5 times normal within 90 days of expiration, 2 times normal from 90 days to 18 months, and a mailed Executive Director approval request (still at the doubled rate) from 18 months out to three years. Past three years lapsed, the technician has to apply as a new applicant rather than renew — and TDLR's enforcement rules fine working an HVAC job on an expired license $1,000-$3,500 as a Class B violation.
