The A/C is set on 76 all day and night with all ceiling fans on full blast. We are trying to keep the power bill a little lower than in years past when we would set it on 70.
In the winter, the heat goes no higher than 62. I am the only one home most of the day, and I am pretty warm-natured. We have blankets available on all chairs, sofas, etc, electric blankets to sleep under, and if we get too cool, we can sit in front of the fireplace for a while.
