Author: Dick Wirz

Now in its third edition, the ever-popular COMMERCIAL REFRIGERATION FOR AIR CONDITIONING TECHNICIANS helps HVAC professionals apply existing skills to new concepts in order to service medium and low-temperature refrigeration equipment such as walk-ins, reach-ins, refrigerated cases, and ice machines.

Chapters emphasize refrigeration in the food service industry, offering practical tips from the author and other seasoned pros on installing, servicing, and troubleshooting commercial equipment.

Freshly updated throughout, the third edition adds more than 150 new illustrations, pictures, and diagrams—including a step-by-step flowchart for quickly diagnosing and addressing the nine most common refrigeration problems on the job—as well as six new sections on the latest advancements in commercial refrigeration.

A handy resource to keep in any truck or shop, COMMERCIAL REFRIGERATION FOR AIR CONDITIONING TECHNICIANS, 3rd Edition, is an indispensable tool for any technician working with commercial refrigeration today.

  • Step-by-Step Diagnostics: Chapter 7 delivers a comprehensive approach for identifying refrigeration problems, including a flowchart which illustrates the key readings to take and logical sequence to follow when diagnosing nine of the most common issues.
  • High Esteem: Recognized as the number one book on commercial refrigeration by instructors and field technicians, the third edition is a practical resource that makes problem-solving easy in both workplace and classroom settings.
  • Tech Friendly: Conversational and fun, chapters deliver refrigeration concepts in an easy-to-understand tone and alongside practical applications.
