when the furnace stops working the fan keeps on going on pushes cold air from outside the house for some time..it does not get cold or anything but I think the …the temp drops and furnace goes back on …
If the indoor furnace blower stops I'd think the outdoor compressor fan should also stop. Your elec. bill must be enormous. Avg US usage is ~700 kwh/mon, max ~3000.
Rule of thumb from another forum: for each hour you'll be away turn down the heat one [or two?] degrees, but this might only be for gas furnaces.
BTW, a 2000 sq ft house, 60 psf live + dead load, interior mostly wood, would take ~800,000 BTU to raise the temp from 61F to 74F. In a perfectly insulated house, you'd get back all this stored energy as the house cools, but houses are not perfectly insulated.
Tabletop room humidifiers of the warm mist variety kill more germs than the cool mist variety.
