Scope of work
A Master Electrician license authorizes the holder to design, install, alter, and supervise all classes of electrical work in Texas, including the authority to qualify an Electrical Contractor business. The license is the highest individual electrical tier issued by TDLR. To qualify, an applicant must hold a Journeyman Electrician license, accumulate two years of journeyman experience, and pass the master exam. Annual renewal requires four hours of continuing education on the current National Electrical Code.
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.
