NATE requires that every NATE-certified technician continues their education and remains up to date to certified standards.


  • Each technician must recertify every two years to maintain their certified status
  • Proof of 16 continuing education hours must be submitted with the renewal application and renewal fee paid directly to NATE
  • HVACRedu.net makes this process simple. With our NATE recognized online classes, this requirement can be met with little trouble

How Does The Program Work?

  • Every course is ONLINE, taken at your own pace.
  • Choose a course that interests you. NATE does not require you to take a specific subject.
  • Successfully complete and pass the course online.
  • HVACRedu.net issues your course completion certificate satisfying the CE Hour requirement.
  • Each of the CE Hour series of courses is valid for at least 16 CE Hours and exceeds the minimum  NATE CE Hour standard of 16 hours.
  • After payment your username and password are sent to your immediatly.
  • The NATE Certificate of Completion is issued upon successfully passing the course.
  • Online Faculty is available to the student during business hours.
