When the Commercial Refrigeration Manufacturer’s division of the Air-Conditioning, Heating and Refrigeration Institute (AHRI) recognized the need to identify the proficiency of technicians who install and service commercial refrigeration systems, North American Technician Excellence (NATE) went to work. Enlisting the help of AHRI, subject matter experts from across the industry, and technicians who volunteered to take beta tests, NATE developed four exams – two that certify technicians in the installation and service of light commercial refrigeration systems and two that certify them in the installation and service of commercial refrigeration systems.
