Type I certification is required for servicing small appliances. It’s ideal for technicians working on refrigerators, freezers, and window AC units containing five pounds or less of refrigerant, commonly found in residential and light commercial settings.
Type II certification is required for servicing or disposing of high-pressure appliances. This includes systems like rooftop units and supermarket refrigeration, where technicians must follow strict procedures to prevent leaks and ensure safe refrigerant recovery.
Type III certification is required for servicing or disposing of low-pressure appliances. It’s especially relevant for facilities professionals and HVAC technicians working with chillers in commercial buildings, hospitals, or industrial plants, where safety and system integrity are critical.
Universal certification allows technicians to service all appliances. It’s the most versatile option for professionals seeking to maximize job opportunities and ensure full compliance across a variety of equipment types and refrigerant systems.
Each certification type includes the required core curriculum, which covers essential EPA regulations, safety practices, and refrigerant handling fundamentals.
