North American Technician Excellence (NATE), headquartered in Arlington, VA, was founded in 1997 and is the nation’s largest non-profit certification organization for heating, ventilation, air conditioning and refrigeration technicians. NATE is the only technician certification organization governed, owned, operated, developed and supported by the HVACR industry.
As our business evolves to meet the growing demands of the HVACR workforce, the company's vision - to be the leader in developing and recognizing professional HVACR technicians - remains clear.

The NATE Technical Committee, comprised of industry experts nationwide, advises NATE on the Knowledge Areas of Technician Expertise (KATEs) and all test item development. KATEs are statistically proven job task analysis from which all questions are developed. To view KATEs for each exam click here. To view a complete list of our technical committee click here.
Any technician working in the HVAC industry is welcomed to take our certification exams. NATE exams assess a candidate’s applied knowledge of their field. Although there are no formal educational requirements for certification, NATE strongly suggests that candidates have some formal training provided by an employer, a technical school or other educational institution.
We recommend candidates have the following work experience as well as some experience with equipment in their specialty:
Earning a NATE certification is proof of advanced level competency as a technician in the HVAC industry, helping you stand out from others in the job market. In addition to advanced training and attaining proficiency with growing trends in the industry, NATE-certification provides a sense of trust to:
Contractors prefer NATE-certified technicians because they remain in the industry longer, have the proven knowledge to do the job right the first time and are more productive than non-certified technicians.
Manufacturers and distributors know that NATE certification encourages proper installation and service, which means fewer warranty returns and, ultimately, a better bottom line.
Educators and trainers benefit from NATE certification's uniform testing standard. Utilities appreciate NATE certification's focus on correctly installing and servicing sophisticated HVACR equipment, which saves energy and money when operating at peak efficiency.
Homeowners look for NATE certification because it ensures that a knowledgeable, well-trained and highly experienced technician will service their home heating or cooling system.
NATE offers two pathways to earn NATE Certification, as well as multiple specialty and senior certifications. To earn NATE Certification, technicians will choose between the Certified HVAC Professional (CHP-5) pathway or the traditional Core and Specialty exam pathway.
Technicians that choose the traditional NATE certification pathway will take two exams – the NATE Core exam and a Specialty exam. NATE offers multiple Specialty exams for technicians to choose from, and will earn an Installation, Service, or Senior certification specialization depending on the exam the completed.
With the CHP-5 pathway, technicians earn their NATE certification through a series of five exams, each on a different subject domain: HVAC Fundamentals, Electrical and Controls, Comfort and Airflow, Installation, and Service.
