I'm in the SouthEast. It gets pretty warm here in the Summers, but we're typically a consistent 5 degrees cooler than Atlanta in the warmer months.
At night, I almost always set the thermostat to 66 degrees (or less in the Winter). I like to sleep in cooler temps. Otherwise, I set the thermostat to 68-72 degrees in the daytime and off if we're not home. That 5 degrees of variance changes depending on what I'm doing and whether or not I'm cooking. If we're cleaning the house or doing projects that make us feel warmer, we crank the AC down. If we're just watching TV...we might raise the temp some.
