Give Use A Shout

HOST A: It is 102 degrees in Kingfisher. The AC has been running all day. The homeowner walks out the back door and the line going into the condenser is wrapped in ice an inch thick. They panic. They call us. What is happening. HOST B: Coil freezing. Number one summer emergency.

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.
