Note: When renewing multiple certifications, all the certification dates will be changed to match the date of the most immediate expiring certification. For example, if you renewed an AC Service certification expiring September 2012 and a Gas Heating Certification expiring December 2012 together, both would have their new certification dates changed to September 2012 with both having an expiration date of September 2017.

Lapsed or Expired Certifications

If you have not recertified your NATE SPECIALTY before its expiration date– at the end of the month printed on your NATE wallet card– your certification is expired. Technicians whose certifications have lapsed or expired are no longer NATE-certified and cannot represent themselves as such. Any technician with an expired certification who represents himself as NATE-certified is behaving in a fraudulent and unethical fashion. These technicians may be denied future NATE certification and be subject to legal action.

To become NATE-certified again, you must retake both the CORE (if required) and SPECIALTY tests. Once you successfully complete the testing process, your new NATE certification will date from the time you pass the new tests.
