Technicians working with natural refrigerants require specialized training and certification due to the unique properties and handling requirements of these substances. Training programs should cover topics such as safety procedures, equipment operation, and leak detection. Certifications, like those offered by organizations like the Air-Conditioning, Heating, Refrigeration Certification Board (ACHR), demonstrate a technician’s competence in handling natural refrigerants. Manufacturers and industry associations also provide training and certification programs for technicians working with specific natural refrigerant-based systems.
