Methodology

How A/C Technician licensing works in Texas

Texas A/C technicians work under a licensed HVAC contractor and hold either a Registered (REG) or Certified (CER) status with TDLR. Certification requires a written exam and verifiable field experience; registration is the entry path for new technicians. A technician's license does not authorize them to operate a business independently — only a licensed contractor may contract for work. Many technicians hold both REG and CER simultaneously during career transitions. EPA Section 608 certification for refrigerant handling is a federal requirement separate from the TDLR license.
