Written by Dick Wirz

The Commercial Refrigeration Program is an advanced program, perfect for HVACR technicians and contractors who want to better understand refrigeration systems used in commercial applications like stores, warehouses, restaurants, and product and food services. The first time the course was offered Dick’s lectures were recorded. Those recordings are included in the asynchronous delivery so you feel like you’re sitting in his classroom. He covers everything you need from refrigeration principles through evaporators, condensers, compressors, metering devices, controls, accessories, motors, and the various refrigerants used so you can service walk-in refrigerators and freezers, and commercial ice makers with confidence. He also describes the most common service issues and troubleshooting procedures.

The courses included in this program are:

  • 441 HVACR Commercial Refrigeration I
  • 442 HVACR Commercial Refrigeration II
