Built for the Real World
The commercial refrigeration industry is a $50+ billion global market. Grocery stores, restaurants, warehouses, and food processing facilities depend on systems that run 24/7/365. When they fail, the consequences are immediate — spoiled inventory, health code violations, and lost revenue. This course prepares you to be the technician who solves those problems.
Equipment-Specific Training
Walk-in coolers/freezers, reach-in units, display cases, ice machines, and supermarket rack systems — each with dedicated lessons.
Real-World Troubleshooting
Five complete service call scenarios that walk you through diagnosis, root cause analysis, and repair — the way it happens on the job.
Food Safety & Compliance
FDA Food Code, HACCP principles, EPA 608 refrigerant handling, and OSHA safety standards — the compliance knowledge employers require.
Advanced Diagnostics
Superheat, subcooling, pressure-temperature analysis, and systematic diagnostic methods that separate professionals from guessers.
Modern Refrigerants
R-404A, R-448A, R-290 (propane), R-744 (CO2 transcritical) — understand the refrigerant transition and what's replacing legacy chemicals.
Certification Aligned
