What is NATE Certification?

North American Technician Excellence (NATE) Certification is one of the widely accepted HVAC certifications in the industry.

All questions in the certification exam are based on KATEs, or Knowledge Areas of Technician Expertise.

As such, having a NATE Certification ensures HVAC technicians possess real-world knowledge and skills to become industry experts.

The good thing is that anyone can take the certification exam, even those without formal education.

The only requirement is that you must have the necessary training or work experience, especially in your specialty.

So if you specialize in an area, you must have the following minimum years of experience:

  • Installation technician – 1 year of experience
  • Service technician – 2 years of experience
  • Senior level technician – 5 years of experience

Building a career in the HVAC industry is both physically and mentally demanding.

That’s why the industry sets high standards and requirements for its HVAC technicians.

One such vital requirement is getting certified.

So what difference does a NATE Certification make in your career?

Maintaining Your NATE Certification

Your NATE Certification is only valid for 2 years.

NATE can grant you recertification in 2 ways.

  • Option 1
    • Complete 16 hours of continuing education hours
    • Pay the renewal fee
      • $25 per specialty
      • $5 per additional specialty
  • Option 2
    • Retake the specialty exam before the expiration date
    • If the expiration date already passed, within the 120-day grace period

Do note that if you still don’t take the exam within the grace period, you’ll have to go over the process again to get your NATE Certification.
