How Much You Could Save
You can save as much as 10% a year on heating and cooling by simply turning your thermostat back 7°-10°F for 8 hours a day from its normal setting, according to the U.S. Department of Energy. The percentage of savings from setback is greater for buildings in milder climates than for those in more severe climates.
In the summer, the department says, you should keep your house warmer than normal when you are away, and sett the thermostat to 78°F only when you are at home and need cooling. Set your thermostat at as high a temperature as comfortably possible. Since it is always very humid in New Orleans, make sure to some sort of add humidity control, if needed. Keep in mind the smaller the difference between the indoor and outdoor temperatures, the lower your overall cooling bill will be.
