Fixing Stubborn Hot Rooms With Mini-Splits

Jun 14, 2026 · 22 min

Give Use A Shout

HOST A: I want to start this one with a scene almost everybody listening will recognize. You walk through your house in August at three in the afternoon, and most of the rooms feel fine. Then you open one specific door, the bonus room over the garage, or the back bedroom on the west side, or the addition the previous owners put on, and it feels like you walked outside. Ten, twelve degrees hotter than the rest of the house. HOST B: That room.

I'm Dave Hartzell at Hartzell's Heat & Air in Kingfisher, Oklahoma. 45 years in the trade, Master HVAC license. On Cool Talk I cover the stuff central Oklahoma homeowners actually need to know about heat, air, and indoor air quality.
