Energy-Saving Facts & Tips

Spring/Summer Tips

Cooling Your Home

  • In the summer, keep your thermostat at 78 degrees or higher to save money. You use 3 to 5 percent more energy for each degree the air conditioner is set below 78 degrees.

  • Set your thermostat 5 degrees higher when leaving your home for an extended period of time. Overall, however, keep the temperature fairly constant. Frequent changes will use more energy.

  • On hot days, close window shades and drapes to keep out the heat of the summer sun.

  • Be sure your air conditioner is properly sized and installed correctly for optimal energy efficiency and comfort. (Remember: a bigger unit isn't always better.) Check with a heating, ventilation, and air conditioning (HVAC) professional to determine the proper sized unit for your home. Learn more about new heating and air conditioning equipment.

  • Shopping for a room air conditioner? Consider an ENERGY STAR® qualified model. They use at least 10 percent less energy than standard models.

Insulation and Air Flow

  • Adequate insulation in your attic, ceilings, walls, floors and crawlspaces can reduce your energy usage by up to 30 percent. In the Midwest, experts recommend 9 to 15 inches of blown or blanket insulation in an attic. If you are building a new home this spring and summer, follow the ENERGY STAR construction guidelines.

  • Call a BPI certified specialist to check your insulation.

  • Clean the air vents regularly. Make sure drapes and furniture do not block the air vents or returns.

  • Set your ceiling fan to blow air downward. This cools the air, allowing you to set your thermostat higher to save on cost. It costs only $2 a month to use ceiling and other fans to circulate air.


  • Plant shrubs, bushes and vines next to your home to create dead air spaces that will help insulate exterior walls in the summer. Make sure to leave at least one foot of space between the wall and the fully mature plant.

  • Shade trees shield your home from the hot summer sun. Be sure to plant the right tree in the right place to avoid potential tree and wire conflicts as the tree matures.
