For the first time ever, North American Training Excellence, Inc. (NATE) will offer certification testing for residential and light commercial hvacr technicians on-site at the AHR Expo, February 7-9 at the Dallas Convention Center. The leading hvacr certification program hopes to reach the thousands of installation and service technicians who will be attending the event, which is the largest hvacr exposition in North America. Those who participate can take certification testing for several different industry areas, including air conditioning, air distribution, gas heating, heat pumps, and oil heating. Testing will be coordinated with local chapters of the Air Conditioning Contractors of America (ACCA), Plumbing-Heating-Cooling-Contractors-National Association (PHCC), and Refrigeration Service Engineers Society (RSES).
