Scope of work
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.
An Electrical Contractor (TECL) license authorizes the business to bid, contract for, and perform electrical work in Texas. Every TECL must designate a qualifying Master Electrician whose individual license backs the contractor license, must carry general liability insurance, and is renewed annually. The TECL is the license a homeowner verifies when hiring a company; the named Master Electrician is the individual whose qualifications support the contractor's authority. Some Texas cities require additional local registration before pulling permits.
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.
