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.

In this episode, we explore a new approach to oil-free centrifugal compression that eliminates magnetic bearings entirely. Instead, this technology uses refrigerant vapor to create a frictionless lift—removing the need for oil or magnets.

In Part 2 of our behind-the-scenes documentary, we step into one of the most intense and data-driven areas of the Johnson Controls Advanced Development and Engineering Center — the compressor test blocks, also known as the gas blocks. This is where YORK compressors are pushed, mapped, and reimagined. You can watch the video version of all episodes on our YouTube channel, HVAC TV.

In this episode, the experts at Greenheck, dive deep into the latest advancements in fan array technology with EC motors and modular designs. Learn how these systems improve efficiency, simplify maintenance, and solve real-world retrofit challenges. We cover fan spacing, motor selection, redundancy strategies, and how modern controls like the Corell controller integrate with BAS systems. Whether you're designing new systems or tackling tough retrofits, this conversation will give you practical insights to optimize performance, reduce downtime, and future-proof your HVAC designs.

In this real and unfiltered conversation, Tony Mormino sits down with Ben Reed (guest host for HVAC Know It All) at AHR Expo 2025 to dive deep into one of the most misunderstood roles in our industry: sales—specifically, sales in commercial HVAC.

Tony shares his personal story of growing up around HVAC, becoming a sales engineer, and how he learned the power of leading with education, empathy, and authenticity instead of slick pitches. Whether you’re a technician curious about the next step in your career, an engineer considering the jump to sales, or just someone navigating the commercial side of the trade—this video is packed with insights.

Join me, Tony Mormino from HVAC TV, as I kick off this exclusive behind-the-scenes tour of JADEC — the Johnson Controls Advanced Development and Engineering Center — alongside my good friend and industry legend, Rob Tanner.In Part 1 of this documentary series, we dive into the Water-Cooled Chiller Test Blocks, where Johnson Controls puts their centrifugal and screw chillers through the paces—testing, refining, and future-proofing some of the most powerful HVAC systems in the world.
