Supermarket rack systems confuse even experienced techs. That stops here.
Learn the core supermarket topics most techs struggle with, explained in a clear, practical, technician-friendly way. Build real confidence with oil, pressure control, TEVs, defrost, and electronic valves.
Supermarket systems don’t behave like standard HVAC.
Different store setups, no structured learning, and components react differently. That’s why most techs struggle with oil, TEVs, head pressure, defrost, and EEVs.
Training shouldn’t feel like guessing.
This workshop gives clear explanations, real rack examples, and troubleshooting methods you can actually use.
Start building confidence, not confusion.
Learn how to speak, service, and diagnose supermarket systems the right way.
Real System Examples
Taken from actual supermarket rack setups, not textbook theory.
Simple Troubleshooting
How oil, TEVs, defrost, and pressure issues behave in the field.
Confidence You Can Use
Know what to do, why you’re doing it, and how to explain it.
WHAT'S INSIDE:
Workshop 1: Oil Management
Learn how oil separator, reservoir, float controls and oil failures actually work and what causes call-backs.
Workshop 2: Head Pressure Control
