In the winter we are set at 62, I love it cold. My poor neighbor, when she comes over she does not take her coat off.

Since building the new house we now have central air and right now at night I put the 2nd floor to 67 and then turn it up to 70 when getting up in the morning. The first floor right now stays off and we open the windows, we get a really good cross wind at the house. Next week it is supposed to be in the high 90's so I figure we will keep the A/C set at 70 downstairs.
