In this episode of HVAC TV, we sit down with Vic Marinich from Danfoss to talk all things heat exchangers—what they are, why they matter, and how they’re evolving to meet the demands of modern HVAC systems.

From chillers and data centers to river water cooling and refrigerant challenges, Vic breaks it all down in a way that's practical and easy to follow—even if it's been a while since you’ve calculated Reynolds numbers (don’t worry, we don’t go there).

In the finale of JADEC: The Tour, Tony Mormino and Rob Tanner step inside YORK’s Air Handler Lab and the massive reverberant sound chamber — where fans and air handlers are pushed to the limits of airflow, static pressure, and sound power. From a 100,000 CFM test system to the precision of accredited sound measurements, this episode reveals how Johnson Controls engineers ensure performance and reliability in the real world.

In Part 7 of the JADEC Tour, Rob Tanner and Tony Mormino dig into one of YORK’s latest innovations — the R8 compressor. Built to offset capacity losses from the transition to low-GWP refrigerants, this open-drive centrifugal design helps deliver up to 3,000 tons of cooling with an added efficiency boost from a unique economizer cycle. You’ll hear how this innovation came to life in JADEC’s labs, what it means for YORK’s YK product line, and why even a few percentage points of efficiency can change the game in large-tonnage chillers.

In this episode of the JADEC Tour, we step inside the hemi-anechoic sound chamber to test the quietest centrifugal chiller in the industry — mostly because it doesn’t have a compressor installed (yet). Rob Tanner explains how YORK measures sound, why decibels matter in chiller design, and how engineers tweak components to make these massive machines run quieter than ever.

Tony talks with Art Hoover of Matrix HG Construction about Bay Area HVAC challenges, from electrification costs to compressor retrofits. They dive into design-build vs. plan-spec, post-COVID building realities, and advice for service techs moving into sales—all with real stories from the field.

In this episode of the JADEC Tour, we go behind the scenes with YORK chiller product engineers Brady Schulz and Austin Reth to uncover what it really takes to work in HVAC product development. From leading tests in a -20°F cold room to fielding feedback from 100+ customers, their stories blend engineering insight with real-world HVAC impact.

Tony Mormino is joined by Louie and Peter from ABB to break down Variable Frequency Drives—what they are, how they save energy, and why they’re essential in today’s HVAC systems. From fan laws to harmonics to ABB’s new smart factory, this episode blends technical insight with real-world perspective (and a few laughs along the way).

In this episode of HVAC TV, Tony sits down with Sean Kelleher, Director of Engineering at RLS (Rapid Locking Systems), to talk about one of the most critical—and often overlooked—aspects of HVAC: refrigerant piping. From common install issues and oil return problems to the rise of press fittings as a legit alternative to brazing, Sean shares valuable insights backed by over a decade of experience.

In this episode, Tony Mormino chats with Nathan Martin from O'dell HVAC Group in Ontario to explore the Canadian HVAC landscape—from custom VRF-enabled air handlers to electrification, decarbonization, and why Canada’s still clinging to the metric system. It’s a fun, insightful cross-border conversation packed with real-world strategies, industry trends, and a few laughs about voltage, refrigerants, and the great Fahrenheit vs. Celsius debate.

Join me inside the LG booth at AHR as I take a closer look at a chiller I definitely didn’t expect to see. Senior VP Steve Scarbrough walks us through LG’s surprising lineup of centrifugal chillers, inverter scroll heat pump chillers, and how AI is shaping the future of HVAC — especially for data centers. We also talk refrigerants, hot water, lead times, and why LG is betting big on this market.
