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.

Journeyman Electrician

A Journeyman Electrician license authorizes the holder to install, alter, and repair electrical wiring in Texas under the supervision of a Master Electrician. A journeyman may not pull permits or operate as an electrical contractor — only Master Electricians and TECL-licensed contractors hold that authority. The license requires 8,000 hours of documented apprentice experience plus the TDLR exam, and is renewed annually with four hours of continuing education on the current National Electrical Code.
