• Air Conditioning System. Have your central air conditioning system serviced before the cooling season begins. Leaking ducts and joints, low refrigerant, worn parts, and dirty air filters can jack up energy use, so make sure every aspect of your system is in top operating condition.
• Keep it Clear Clear all brush and debris from around the unit so air can circulate - if the motor doesn't have to labor, it will use less energy.
• Change your Filter if you have user-serviceable filters, be sure to change them monthly. They're inexpensive, and clean filters help keep the compressor operating efficiently.
• Plant a Tree! Not only to shade the house, but to shade the AC unit, too. If the unit has to expend energy to cool itself, it will have to work harder to cool your house's interior.
• Adjust your Thermostat Set the thermostat as high as is comfortable for you and your family. Just a few degrees higher than usual can have a significant positive impact on energy use with little negative impact on comfort.
• Check the Surroundings Make sure the thermostat is placed away from lamps, sunny windows, and other heat sources that can keep the AC unit running unnecessarily.
• Dehumidify your Home. Use a dehumidifier to remove moisture from the air - dry air feels cooler than moist air.
• Cover Windows. Cover windows on the sunny side of the house during the hottest part of the day.
• During the Day...If no one is home most of the day, set the AC to turn on an hour before you arrive. No need to pay for cool air that no one is enjoying.
• At Night... Set your thermostat timer to raise the temperature at night. Body temperature drops as we sleep, so air that's comfortable during the day will be too chilly during slumber.
• Close Windows and Doors When the AC is running, keep doors and windows closed to minimize loss of cool air.
• Circulate the Air Make sure the attic is well insulated and well ventilated. Efficient air circulation keeps the temperature down and saves on cooling costs.
• Enjoy the Breeze! Consider using air conditioning only on the hottest days of the year. Instead, take advantage of cooling breezes through open doors and windows - you'll save money and the environment too!
