The acronym NATE stands for North American Technician Excellence. It is the leading non-profit certification program for technicians who work in the heating, cooling, ventilation, and refrigeration service industries. To be certified a technician must pass rigorous industry tests that measure their knowledge and competence for all types of HVAC equipment and systems. These industry competency exams are supported by all six of the national organizations that oversee and monitor the high standards expected in the HVAC industry. At Summers & Zim’s we require all of our technicians to pass the NATE test standards before they work in our customers’ homes. It is another way we guarantee that our customers receive only the highest quality of service.
