Which certification is considered a universal license for handling all types of refrigerants?

• A. Type 1 certification
• B. Type 2 certification
• C. Type 3 certification
• D. Universal certification

Answer: (D)

The universal certification is designed to allow individuals to handle all types of refrigerants, including CFCs, HCFCs, HFCs, and other refrigerants used in various applications. This certification encompasses the knowledge required for Type 1, Type 2, and Type 3 certifications, which focus on specific categories of refrigerants and systems.

Type 1 certification is limited to servicing small appliances, while Type 2 certification covers high-pressure refrigerants and Type 3 certification is for low-pressure refrigerants. Universal certification is essential for HVAC technicians and others in the refrigeration industry who need the versatility to work on a wide range of systems and refrigerants without needing multiple certifications. This reflects the comprehensive skill set required to safely handle refrigerant recovery, recycling, and management practices that comply with EPA regulations.
