Quiet By Design: Mike Dawson on Noise Control Innovation
04/07/2026 | 37 mins.
Today on Cool Air, Hot Takes™, hosts Charlie Jelen and Dan Gentry sit down with Mike Dawson, VP of Sales at Parklane Mechanical, a company that's been solving industrial noise problems for over 30 years. Data centers are booming, and we've all heard the noise about them. Turns out, they're also just literally loud. Neighbors have opinions about that. Mike breaks down how noise control works, why it needs to be part of the conversation earlier than most people think, and what the job looks like on the ground.

We also have:
HVAC Headlines: How data centers helped keep the lights on during Winter Storm Fern, Trane's new collaboration on oil-free compressor technology, and a 25-year cheese study that has absolutely no business being this interesting.
Stat of the Day: Which U.S. states gained the most residents in 2025.

Electrification, CDUs, Data Centers: The Hottest Takeaways from AHR 2026
03/24/2026 | 29 mins.
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:
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.
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.
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.
Spencer Ingaldson, Darcy Solutions: Groundwater-enabled geothermal that delivers 50x the capacity of a traditional well. Yes, really.
