Scope of work

What these licenses authorize

A/C Technician

An A/C Technician license authorizes a person to perform HVAC installation, alteration, and service work in Texas under the direct authority of a licensed HVAC Contractor. A Certified (CER) technician has passed the TDLR exam and accumulated verifiable field experience; a Registered (REG) technician is in the entry pathway. Neither status authorizes contracting for work independently — only a licensed contractor may bid and contract. Refrigerant handling additionally requires federal EPA Section 608 certification.

Apprentice Electrician

An Apprentice Electrician license authorizes the holder to perform electrical work in Texas under the direct supervision of a Journeyman or Master Electrician while accumulating the 8,000 hours required to test for the journeyman license. An apprentice may not work unsupervised, may not pull permits, and may not contract for work. The license is the entry point for an electrical career in Texas and is the most numerous electrical license type held statewide.
