- Check the filter at least once a month during the warm season and clean it as needed.
- Use the fan setting at night when the air outside is cool, or open a window and leave the air conditioner off. Keep windows closed whenever the air conditioner is on.
- Use the air conditioner's timer and set it to turn on no more than 30 minutes before you expect to return home.
- The lower you set your temperature, the more it will cost. For example, a 75° setting will cost about 18 percent more than a 78° setting.
- Plant hollyhocks, clematis vines or other shade-producing plants in front of east and west facing windows to reduce the need for air conditioning.
