i don't care how long it runs (it is 100F today outside) , i want to be cool, so 73F keeps it nice and cool inside
my electricity bill last month with the heatwave was about $230 , that isn't bad
i have a ground source heat pump and the house is only 3 years old with good insulation/good windows and has a walk out basement
i want to be comfortable, if i didn't want to be comfortable, i would live in a trailer without A/C or in a van down by the river
