OK, so yesterday morning, we awoke to a temperature of 60º inside the house! Obviously our heat pump had stopped working overnight! And naturally our American Home Shield warranty just ran out 3 weeks ago! So my dear and wonderful husband, who is an electronic technician, decided to look at a few obvious (to him) things, before calling for service. He found a loose connection on something, fixed it, and saved us who knows how much $$$ on a service call!!! Now today it's 2º outside, but a balmy 74º inside!!! Yeah!
