Why Train With Us
Most NATE classes cost you two full weekdays and still leave junior techs guessing on heat pumps.
We do it in one Friday afternoon + Saturday so you only lose half a day of production.
Traditional paper testing. No webcam monitoring or software issues. They walk out actually knowing how to troubleshoot.
We kept paper testing for a reason, in professional venues - not a computer lab, not a warehouse.
Distributor-level diagnostic instruction from real field experience.
Small class size for better support and higher pasing rates.
Don't rely on the next rigid, midweek, Zoom meeting where they can't have one on one help
What To Expect
*Live review and instruction focused on real-world diagnostics
*Official NATE Core and/or Heat Pump Service exams (paper-based)
*Study materials, coffee, and light refreshments included
*Clear confirmation and logistics details sent after registration
What They Say About Shawn's Instruction
"Shawn's diagnostic layouts completely changed how our installation crews troubleshoot boards in the field. He cuts past the generic handbook fluff and teaches real tech math that eliminates callbacks."
