Keep air conditioner filters clean. Air conditioner filters should be cleaned or replaced once a month during use. |
| 2 |
Maintain unobstructed airflow around vents and filters. |

Maintain 78ºF (26ºC). For every degree you lower the temperature, the energy costs rise by 6 percent. A temperature setting of 75ºF (24ºC) costs 18 percent more; a 72ºF (22ºC) setting costs 36 percent more. |

Use a programmable thermostat. No need to run the air conditioner when no one is home. Set timers to have the air conditioning come on 30 minutes before anyone arrives home. |
| 5 |
Keep doors closed. Enter and exit your home quickly to keep cooled air in the house. |
| 6 |
Install a ceiling fan in rooms that are used often. Occupants feel as cool under a ceiling fan at 82ºF (28ºC) as in 77ºF (25ºC) still air. |
| 7 |
Insulation is important. Make sure your home has the appropriate amount of insulation in walls, attics and crawl spaces. |
| 8 |
Open windows at night. To take advantage of naturally cool night air when possible. |
| 9 |
Plant deciduous shade trees. Shade trees absorb radiant heat before it warms your house, and planting trees helps clean the air, too. |
