USE YOUR WINDOWS TO GAIN COOL AIR AND KEEP OUT HEAT

OPERATE YOUR THERMOSTAT EFFICIENTLY
Set your thermostat as high as comfortably possible in the summer. The smaller the difference between the indoor and outdoor temperatures, the lower your overall cooling bill will be.
Keep your house warmer than normal when you are away, and lower the thermostat setting to 78°F (26°C) only when you are at home and need cooling. A programmable thermostat can make it easy to set back your temperature.

Avoid setting your thermostat at a colder setting than normal when you turn on your air conditioner. It will not cool your home any faster and could result in excessive cooling and unnecessary expense.
