Training and Time Management
The online program model is called an Asynchronous Learning Network (ALN). Studying is done on each tech’s own schedule, on his time and at his place; but a commitment to regular study is essential to ensure completion of each course within its 60-day enrollment. Students can move through course material more quickly or take the full 60 days per course, as they choose.
After you successfully complete the first group of courses with a grade of 75% or more, you are ready to take your first NATE Ready-to-Work (RTW) Certificate Exam. The RTW exam is not a proctored exam. Any tech can purchase the exam on their own (it comes with a PDF study guide) and take it at home. The exam fee will be refunded to you in full! All we need is for you to email us proof that you passed the exam and a copy of your paid invoice/receipt. We will mail you a check.
But this program doesn’t end there – we continue to train you for higher levels of NATE Certified HVAC Technician credentials. After you successfully complete the second group of courses, you are ready to take the NATE Core Exam at the service level. Again, the NATE Exam fee will be refunded to you in full! Just send us proof of your passing the exam and a copy of your paid invoice/receipt.
Once you have passed the NATE Core Certification Exam, you will be ready for the third group of courses. When they are successfully completed, you will be prepared for the NATE Air Conditioning Specialty Service Level Exam, the focus of this program. Send us your proof of passing the exam with a copy of your paid invoice/receipt, and we’ll reimburse you for the exam fee.
And finally, the program concludes with EPA 608 Prep and exam. You’ll be reimbursed for the exam fee, just as described above.
When you reach the end of the program you will receive a Certificate of Completion for the NATE Certified HVAC Technician Program. This is the program that pays you for upskilling your credentials. You can be proud of your Certificate and your NATE Certification!
