What is NATE certification?

NATE certification stands for the North American Technician Excellence, the largest nonprofit independent certification organization in the United States for heating, ventilation, air conditioning and refrigeration technicians. It is a nationally recognized organization that offers optional certifications developed and supported by industry professionals.

NATE certification establishes a level of professionalism and high-quality standards, making it easier for consumers to make informed decisions when choosing technicians and companies to install, maintain or repair heating and cooling equipment in their homes or businesses. You can earn both installation and service certification, specialize in oil, gas or other heating and cooling areas and gain senior level technician status through various NATE certification tests.

A NATE certification exam tests a technician on the following concepts:

  • Basic construction, scientific and electrical knowledge

  • Safety, equipment and tool essentials

  • How to achieve home comfort conditions

  • How to measure temperature and humidity

Who uses NATE certification?

The NATE certification applies to individual technicians who pass a knowledge exam that tests their understanding of HVAC systems. To earn your NATE certification, you must pass the core service test and one specialty exam, like gas furnace, air conditioning or air-to-air heat pumps.

Several national organizations, including the Environmental Protection Agency (EPA) and the American Society of Heating, Refrigeration and Air-Conditioning Engineers recognize and partner with NATE, along with other contractors, distributors, educators, technicians, utilities and manufacturers.

There are many benefits to earning your NATE certification, including these:

  • Access marketing resources: Earning your NATE certification allows you to advertise your achievement, and the organization provides elements like the NATE logo and decals, marketing materials, brand guidelines, apparel, accessories and more.

  • Grow business: Companies can advertise as NATE certified installers when 25% or more of the technicians hold NATE certification. This can attract customers and manufacturers, who often equate NATE certification to quality installation, fewer warranty repairs or returns and ultimately better service, lower energy bills or more profits.

  • Become an official NATE contractor: While the NATE certification is specific for individual technicians, contractors and companies of all sizes can take part as official NATE contractors through a coordinated program with the organization. It gives you access to a potential new customer base by listing on the NATE contractor locator site.
