Season 4 is here! Hosts Charlie Jelen and Dan Gentry are back in the studio, fresh off the floor at AHR 2026 in Las Vegas, where the Cool Air, Hot Takes™ booth was open for business, t-shirts were flying, and the industry had lots to say.

This week, Charlie and Dan break down their hot takeaways from the expo — from the CDU arms race taking over every corner of the exhibit hall, to a surprising surge in electrification energy that nobody quite saw coming.

Live from the AHR Expo floor, we hear from:

1. Allison Clements, Design Engineers: A hot take on the gap between elegant design and real-world operability and why your maintenance guy needs to be in the room.
2. Ray Reiling, Trade Water: Why end-of-life refrigerant is everybody's problem and almost nobody's responsibility, and what you can do about it.
3. David & Conrad Bishop, Twin Bishop Strategies: How the service industry is about to get hit hard by the scale of data center growth and why working smarter isn't optional anymore.
4. Spencer Ingaldson, Darcy Solutions: Groundwater-enabled geothermal that delivers 50x the capacity of a traditional well. Yes, really.
