In this special end of year episode, hosts Charlie Jelen and Dan Gentry are flying solo and taking you on a tour of 2025’s hottest (and coldest) takes. From bold industry predictions and legendary pop-ins, to the now iconic reminder to “never fall in love with a bearing technology,” the guys look back at the takes that shook the HVAC world, and the ones that never quite left the factory floor. (Yes, Dan, we’re looking at your season 1, episode 1 hot take. Was it the coldest of the year? You tell us.) We also have: HVAC Headlines: How Trane and NVIDIA are shaping AI thermal design Hottest & Coldest Takes of 2025:  the death of liquid cooling, bringing your own power to the data center industry and draining water heaters.
