We walked into the house this afternoon after church and potluck to a blast furnace!
We're not sure what's wrong, but something most definitely is. This morning before leaving, I closed the windows and set the AC thermostat at 78 degrees, knowing that the outside temperature was headed for the upper 90s at least. When we arrived home and it was far hotter inside (poor dogs!) than outside (at 96°), I thought I'd messed up somehow, but no. The heat was set for 50°, the AC was set for 78°, and the control was set for 'Auto' – but HOT air was blowing from all the vents! Rick fiddled with the thermostat and thought he had cool air blowing before he left to take Brian to a friend's, and the dogs and I retreated to the blessedly cool daylight basement with lots of water. Thirty minutes later when I went upstairs to let the dogs out (they had guzzled that water), hot air was blowing from the vents again. I turned everything to 'Off' and retreated again, trying not to panic.
Our old, half-dead heat pump cooled just fine; it was the heating function that had quit. This is the first time we've used the cooling function on the new heat pump; the heating function worked last winter. Guess we should have kept the old one for cooling and the new one for heating! Just kidding; trying to keep a positive outlook until we can have someone look at things. Of course, we are experiencing the hottest weather of the year right now . . . of course.
That's it from the oven at . . .
