The technician must demonstrate competence in communication, math and science, ethics, safety, use of fabrication tools, hazardous materials, measuring temperature and humidity and basic knowledge of electrical. - Each NATE certified technician must also pass specialty exams covering installation, maintenance and/or repair of the heating and cooling systems in which he specializes. ## Three Certifications - Installation technician - Service technician - Senior level technician It's suggested that technicians have at least one year experience before taking the installation technician test, two years for the service technician test and five years for the senior technician test.
