Scope of work

What these licenses authorize

Master Electrician

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.

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.
