USE YOUR WINDOWS TO KEEP OUT HEAT
Install window coverings to prevent heat gain through your windows during the day.
OPERATE YOUR THERMOSTAT EFFICIENTLY
Set your thermostat at a temperature you find comfortable and that provides humidity control, if needed. 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 when you return home and need cooling. A programmable thermostat allows you to do this automatically and without sacrificing comfort.
Avoid setting your thermostat at a colder setting than normal when you first turn on your air conditioner. It will not cool your home any faster and could result in excessive cooling and unnecessary expense.
USE FANS AND VENTILATION STRATEGIES TO COOL YOUR HOME
Turn off ceiling fans when you leave the room. Remember that fans cool people, not rooms, by creating a wind chill effect.
When you shower or take a bath, use the bathroom fan to remove heat and humidity from your home. Your laundry room might also benefit from spot ventilation. Make sure bathroom and kitchen fans are vented to the outside (not just to the attic).
