Everything You Need To Know About NATE Certification

Heating and cooling systems are common in homes and businesses to provide a comfortable indoor atmosphere regardless of the season or weather.

These systems are installed and maintained by the HVAC industry, and you can become a NATE certified technician in this field.

NATE certification can lead to additional career options, higher income, and improved customer and client health, safety, and comfort. 

In this post, we’ll look at all you need to know about NATE certification, including what NATE certification is, how to earn it, and the numerous benefits of NATE certification to see whether it’s something you want to pursue.

What is the NATE certification?

The US Environmental Protection Agency and ASHRAE® have formed a coalition called NATE, which stands for North American Technician Excellence (the American Society of Heating, Refrigeration and Air-Conditioning Engineers).

This is the biggest nonprofit independent certification organization for heating, ventilation, air conditioning, and refrigeration technicians in the United States. It is a nationally renowned organization that offers industry-developed and approved optional certifications.

The NATE certification exams are developed in collaboration with a nationwide group of HVAC professionals. The committee creates examinations for technicians by identifying Knowledge Areas of Technician Expertise (KATEs) based on their own real-world employment experience. A technician becomes NATE-certified after passing all of the required tests.

NATE certification establishes a degree of professionalism and high-quality standards, allowing consumers to make more educated decisions when selecting professionals and firms to install, maintain, or repair heating and cooling equipment in their homes or offices. 

Through several NATE certification tests, you can receive installation and service certification, specializing in oil, gas, or other heating and cooling fields, and advance to senior-level technician status.

Note that technicians who earn their NATE Heat Pump certification also earn their Air Conditioning certification. An Installation certification is given to technicians who acquire a Service Specialty certification.

Who uses NATE certification?

Individual technicians who take and pass a knowledge exam testing their understanding of HVAC systems earn the NATE certification. You must pass the basic service exam as well as one specialist exam, such as gas furnaces, air conditioning, or air-to-air heat pumps, to get your NATE certification.

The Environmental Protection Agency (EPA) and the American Society of Heating, Refrigeration, and Air-Conditioning Engineers, as well as other contractors, educators, distributors, technicians, manufacturers, and utilities recognize and partner with NATE.

Why is NATE Certification important?

When looking for an HVAC professional, make sure they are NATE certified. Because NATE-certified technicians ensure a high-quality experience, you can rest assured that you’re getting good value for your money.

Because of the extensive training and testing required to become NATE certified, your Gallagher’s Plumbing, Heating and Air Conditioning specialist will be able to handle almost any HVAC problem promptly and efficiently.

Choosing a technician who isn’t NATE qualified can have serious consequences. You have no way of knowing how much experience a technician has without certification. They could have decided to start their company yesterday and have no prior experience with HVAC systems. You’d have no way of knowing, which means you could end up with mediocre outcomes that cost a lot of money to fix.

What is tested on NATE?


Although HVAC technicians frequently work on both residential and commercial properties, they must have a thorough understanding of all the components of a domestic heating and cooling system in order to pass the Ready to Work Certificate Exam.

Knowing the blower motor, heat exchanger, combustion chamber, evaporator, condenser, and thermostat is a good place to start.


Many situations require troubleshooting to identify the issue, which is why having the correct tools is critical for any effective HVAC expert.

For instance, a technician should have quick access to reciprocating saw blades, a refrigerant scale, a vacuum pump, a cordless drill, pipe wrenches and pliers, tin snips, screwdrivers, and shears.

Measurements and Units

As an HVAC technician, you must be familiar with measurement calculations and units because the results are frequently used to determine how to proceed in the field.

To size an air conditioner for a home, for example, you must consider square footage, BTUs, and the number of people who will be living there. Precise measurements serve to maximize the unit’s efficiency in the end.

Basic Heat Transfer

When troubleshooting systems that utilize vapor or steam, an HVAC technician should understand the principles of heat transfer since it may provide insight into the issue. Furthermore, understanding how heat is transferred can help to determine why residential dwellings have issues such as being too hot upstairs and too chilly downstairs.

General Safety

As a technician, you must be knowledgeable of all applicable safety standards and regulations, as well as potential job dangers and procedures. All of this is done to guarantee that you don’t put yourself at risk due to chemical exposure, insufficient equipment, or ladder safety.

Electrical Safety

When working on systems, HVAC technicians are constantly faced with electrical problems, which is why learning and appreciating electrical safety is critical. For example, you should understand when to de-energize equipment, what PPE is and how to apply it, and how to test circuits before working on them.

Is NATE certification worth it?

Is NATE worth your time and effort to earn? Earning your NATE certification has numerous advantages, including the following:

Create a career path

Whether you have little prior experience or a lot of it, earning an industry certification can help you advance your career. If you’re thinking about starting your own HVAC company or working as an independent contractor, the NATE certification can help.

Increase your earnings potential

Earning the NATE certification generally leads to higher-level work, with better starting compensation and the possibility of receiving raises and bonuses based on your level of knowledge and experience. Because companies and customers value official ratings and credentials, it can set you apart from other job seekers.

Improve your knowledge, efficiency, and skills

NATE certification gives education about the industry with a uniform standard of understanding as technology improves and changes in the heating and cooling area. In the area of residential and commercial HVAC and refrigeration, NATE-certified technicians are frequently regarded as experts.

Employers and customers alike value specialist certifications and credentials, which can lead to additional work prospects, professional advancement, greater incomes, and more client demand. The NATE certification typically leads to professional longevity and success, as well as the ability to stay on top of regulatory and technical developments throughout the business.

Acquire marketing resources

When you earn your NATE certification, you can use features like the NATE logo and decals, brand guidelines, marketing materials, gear, and accessories to promote your achievement.

Expand your business

Companies can market themselves as NATE certified installers if at least 25% of their technicians are NATE qualified. Customers and manufacturers frequently associate NATE accreditation with quality installation, fewer warranty repairs or returns, and, as a result, improved service, reduced energy costs, or increased profitability.

How to get NATE certified?
