savings in the summer
Air Conditioners: Clean filters once a month. A clean filter helps the unit run better. Set temperature Higher – Raising the temperature on you air conditioner can save you money. In warm weather, the thermostat at home should be set at 78 degrees. (Don't do this, of course, if it will cause health problems for anyone in your family.) When no one is home, set the thermostat at 85 degrees. That way, you'll reduce the need for air conditioning and you will save energy.
If you have ceiling fans or other fans, turn them on. The blowing air can make you feel 5 degrees cooler, without running the family's air conditioner. Fans use a lot less electricity than air conditioners!
Shades: Close them during the day, especially on the east and west sides of your home.
Windows: Close them during the hottest hours of the days. At night, open window opposite one another for cross ventilation.
Exhaust Fans: Got them in the bathroom and kitchen? Use them. They remove heat and moisture.
Ceiling Fans: Use them to reduce cooling costs. A ceiling fan with the air conditioner on low will provide the same comfort as an air conditioner set to high and will save you more money.
