The Online Refrigeration Training Program is an advanced, fully online curriculum designed for HVACR technicians, contractors, facilities personnel, and commercial maintenance professionals who want a deeper understanding of commercial refrigeration systems used in supermarkets, restaurants, warehouses, food service, and other commercial environments.
Training begins with the Fundamentals of Refrigeration with Chris Compton and progresses into advanced commercial refrigeration courses with industry expert Dick Wirz. Many of Dick’s original webinar lectures (Courses 441 and 442) are included, giving you the feel of a live classroom experience. Throughout the program, you’ll gain practical, system-wide knowledge covering refrigeration principles, evaporators, condensers, compressors, metering devices, controls, accessories, motors, refrigerants, service procedures, and troubleshooting.
Total Instruction: 86 Hours
