New Low-GWP Refrigerants Certification Exam

NATE is proud to introduce a new low-GWP refrigerant certification exam. The exam is designed to validate a technician’s knowledge of the low-Global Warming Potential (GWP) refrigerants becoming common in the HVACR industry due to new state and federal regulations.

These new products have additional safety concerns and procedures. The NATE low-GWP refrigerant exam is designed to ensure that HVAC engineers and technicians have the necessary skills and job knowledge to handle refrigerants of all types, with a strong emphasis on the safe handling and use of these new refrigerants.

The certification exam is designed for technicians with at least two years of HVACR experience and helps prepare technicians for changes in:

    • Safety
    • Codes and Standards
    • Transportation and Handling
    • Storage and Packaging
    • Installation, Operation, and Maintenance
    • Recovery, Reclamation, and Destruction

The closed-book exam contains 100 questions and has a 2.5 hour time limit.

What are Low-GWP Refrigerants?

With the passage of the American Innovation and Manufacturing Act (AIM Act), HFC refrigerants will be gradually phased out. The alternative refrigerants being used have additional safety concerns such as flammability. The new certification addresses these new safety concerns being ensuring technicians have the skills and job knowledge necessary to use these new refrigerants safely.

AHRI offers an interactive map of the United States listing state and local building codes and legislation passed to allow equipment using A2L refrigerants, as well as a video series about the industry’s transition to low-global warming potential refrigerants.
