HVAC License: Required for Technicians in Your State?

To become an HVAC or Refrigeration technician, what licensing or certifications do you need to earn? This is a tricky question, because HVAC license requirements vary by state. 

We’ll start with an overview of the one certification EVERY technician needs. Then we’ll cover the licensing requirements by state. And finally, we’ll share some additional certifications you can earn that can set you apart from the rest.

EPA 608 certification is required for every HVAC technician

Refrigerants can be dangerous to work with and potentially harmful to the environment if not handled properly. That’s why the EPA’s Clean Air Act requires technicians (such as HVAC and Refrigeration technicians) who work with refrigerants to be certified. It’s called Section 608 Technician Certification. The certification test ensures you know how to work with these sensitive materials safely and responsibly.

This certification is not an HVAC license, but rather proof (at the national level) that you are trained and qualified to work with the refrigerant chemicals that power air conditioning and refrigeration systems.
