Licensing in Texas

There are two different licensing classes in Texas when it comes to heating, air conditioning, and refrigeration. These are the Class A and Class B license. Class A allows you to handle units regardless of their size, while Class B limits you to cooling systems not exceeding 25 tons and heating systems not exceeding 1.5 million BTUs per hour.

With a license, you can take on any HVAC projects provided that you have the appropriate license in accordance with the types of units you’ll be working on. Keep in mind that you can take the HVAC certification program either on-site or online, thereby making it rather convenient.

Of course, make sure you have carefully reviewed all the licensing requirements so you won’t run across any problems during the application and examination process.

  • A minimum of 4 years of experience in the repair, maintenance, and installation of AC units and refrigerators under a licensed technician’s guidance in the past 6 years
