In the summer? I have no AC at my house but it doesn't usually go above 77 - 80 on it's own. It's in a unique part of the city where we're surrounded by the woods and trees which provide a lot of shade and cool the air. Also the house is built into the side of a mountain and surrounded by massive retaining walls, so the first floor is basically a story underground. Our bedroom is also on the first floor, so I don't really go upstairs except to do laundry.
In the winter, usually about 64 - 67. It goes down to 60 during the day on a schedule or whatever.
