Episode 201: Heatcraft’s Chris Thomas Talks Refrigeration, Training & the Future

Commercial refrigeration is changing fast—but the fundamentals still matter.In this episode of Commercial Kitchen Chronicles, Pat sits down with Chris Thomas of Heatcraft Refrigeration Products for a deep dive into refrigeration, technician training, troubleshooting, system charging, controls, and where the industry is headed.Chris brings more than four decades of HVAC/R experience, from residential and commercial HVAC to chillers, supermarket rack refrigeration, technical training, field support, and his current role supporting technicians and products at Heatcraft.We get into Heatcraft itself, including the history behind brands like Bohn, Larkin, Chandler, Climate Control, and Magna, along with the evolution of refrigeration controls from Beacon to today's intelliGen platform.One of the biggest themes of this episode is something every technician needs to hear:Understanding how equipment is SUPPOSED to operate is the foundation of troubleshooting it when something goes wrong.Chris explains how modern controls can give technicians valuable system information before they arrive on site—including temperatures, superheat, operating conditions, and even the ability to initiate a defrost remotely. Technology isn't replacing the technician. It's giving a knowledgeable technician better information.But technology can't replace fundamentals.We talk about technician curiosity, asking WHY instead of simply looking for an answer, learning sequence of operation, reaching out for help, and investing as much into training as we invest into tools.Then we get into a conversation guaranteed to get refrigeration technicians talking:How should you actually charge a commercial refrigeration system?Chris breaks down charging problems Heatcraft encounters in the field and why relying on shortcuts, rules of thumb, or a clear sight glass can send technicians in the wrong direction. We discuss receivers, line length, refrigerant differences, manufacturer charging information, and why system design and application matter.We also talk about proper installation and maintenance. Even the best refrigeration equipment depends on correct sizing, installation, commissioning, service, and maintenance.Throughout the conversation, Chris and Pat get into:• Commercial refrigeration troubleshooting• Heatcraft refrigeration equipment• Bohn, Larkin, Chandler & other Heatcraft brands• intelliGen refrigeration controls• Walk-in cooler and freezer systems• Refrigeration system charging• Sight glasses and refrigerant charge• Receivers and liquid-line considerations• Superheat and subcooling• System sizing and application• OEM technical support• Technician training and continuing education• Analog vs. digital refrigeration tools• Troubleshooting without jumping to conclusions• Building strong fundamentals• The future of commercial refrigerationWhether you're a seasoned refrigeration technician, just getting started in HVAC/R, or responsible for training the next generation, there's something in this conversation for you.The biggest takeaway?Stay curious.The technicians who keep asking questions, keep learning, understand the fundamentals, and aren't afraid to admit when they don't know something are the technicians who will be prepared for whatever refrigeration throws at us next.https://www.heatcraftrpd.com/Catch up with Chris Thomas https://www.linkedin.com/in/chris-thomas-8b12031b2/Commercial Kitchen Chronicles is the original foodservice equipment repair podcast—built by technicians, for technicians.If you work on commercial refrigeration, walk-in coolers, walk-in freezers, restaurant equipment, HVAC/R, ice machines, cooking equipment, warewashing equipment, or foodservice equipment, follow Commercial Kitchen Chronicles so you don't miss the next episode.If you enjoyed the conversation, leave a rating or review and share it with another technician.https://commercialkitchenchronicles.com/
