Well, my electrical inspection and final heat pump installation happened this morning, so I'll now have cool air on demand. They may need to come back and install a pole of some sort in front of it to protect it from drunk and/or careless drivers, as is apparently the code around here. (It's at the end of one of my carports.)
I'm glad to have it in. Now I just need to "set it and forget it." I've got a neat little programmable touchscreen thermostat with all sorts of features that I need to learn.
