What is NATE Certification in Heating Repair Service?

When you see the letters NATE, what do they stand for? The North American Technician Excellence certification logo connected to an air conditioning and heating repair service tells an important story. In fact, understanding the significance of professional certification organization affiliations and stamps of approval can be an important road sign to look for when choosing a company to perform work for you.

According to NATE’s own website, it is an independent, third-party non-profit certification body for HVAC and HVAC/R technicians.


“NATE’s certification tests represent real world working knowledge of HVAC and HVACR [the R stands for refrigeration] systems and candidates can earn installation and/or service certification in one or more specialty areas. NATE certification tests are developed by the NATE technical committee. The NATE technical committee is comprised of industry experts who developed and oversee NATE’s Knowledge Areas of Technician Expertise (KATEs). Each exam is developed based on these knowledge areas of expertise. The technical committee represents a wide variety of perspectives including contractors, educators, manufacturers, and utilities….”

All of the NATE tests are rigorous, multiple-choice, knowledge-based tests and validate a technician’s knowledge. NATE candidates may earn Installation and/or Service certification in one or more SPECIALTY areas, including:

  • Air Conditioning

  • Air Distribution

  • Heat Pumps

  • Gas Furnaces

  • Oil Furnaces

  • Hydronics Gas and Oil

  • Light Commercial Refrigeration

  • Commercial Refrigeration

  • Ground Source Heat Pump Loop Installer

Advantages for All with NATE Certification

Per NATE, the most major product they supply is consumer certainty. This affects the trade in a variety of ways. A recent study indicates that fully 88% of homeowners believe only certified technicians should be installing or repairing “home comfort” systems.


Poorly installed and ill-serviced equipment is a known factor in higher energy costs and waste. This affects consumers, utilities and even government bodies devoted to assuring everyone has access to enough power. It also places unwanted stress on the already straining power grids and fuel suppliers around the country. It contributes to increased and unwanted environmental pollution due to the extra power generation and burning of fuels.

NATE Certified Heating Repair Service and Installation the Natural Choice

Every AC and heating repair service is adversely affected as well, since a whopping 50% of potential customers put off new installations or retro-fits simply because they do not know what contractor they can trust to do a good job. Manufacturers are adversely affected because as many as one-third of all units returned under warranty as defective are actually the product of installer errors.

A properly trained technician performs installations, maintenance and repairs efficiently and quickly, allowing for lower fees to customers. Installations tend to function better, cost less to operate, and last longer. When opting for AC or heating repair service, installation or regular maintenance, be sure to look for the NATE logo for the reassurance that you will be getting the best help possible.
