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.

HVAC Contractor

An HVAC Contractor license authorizes a business to install, alter, repair, and service air conditioning and refrigeration equipment in Texas. A Class A license covers equipment over 25 tons; Class B covers under 25 tons. The contractor must designate a Responsible A/C Contractor whose name backs the license and is named on every contract. The license does not cover gas-fired equipment outside the HVAC system, electrical work beyond the unit disconnect, or refrigerant handling for technicians, which requires federal EPA Section 608 certification.
