The Human Diagnostic
by Dave Hartzell's Heat & Air - Kingfisher,OK
Looking for honest stories about people, not product reviews? You're in the right place. The Human Diagnostic isn't a how-to HVAC podcast. It's what a 45-year Master Technician notices about people after 90,000 service calls across gas plants, oil rigs, hospital preservation systems, high-rises, feedlots, walk-in freezers, and residential homes all over Central Oklahoma. Hosted by Dave Hartzell, each episode tells a real story from a real service call. Sometimes he's driving to the job and predicting what he's about to walk into. Sometimes he just left and he's still working through what he saw. Either way, the story turns out to be about more than HVAC. Topics you'll hear across the season: ✅ The customer nobody wanted to take, and what changed when someone finally did ✅ Why the person researching their broken AC at midnight isn't being difficult, they're scared ✅ What 45 years of walk-ins, weddings, funerals, and broken water heaters teaches you a

The Generation Gap I Expected at the Heat Pump Never Showed Up
