Scope of work
What these licenses authorize
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.
Electrical Sign Contractor
An Electrical Sign Contractor license authorizes a business to install, repair, and service electric signs and outdoor illuminated advertising in Texas. The license is held by a business and must designate a qualifying Master Sign Electrician. Sign work is a separate license class because it intersects with structural mounting and outdoor electrical scope distinct from general electrical work.
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.
