Landscape
- Plant trees or shrubs to shade air conditioning units but not to block the airflow. Place your room air conditioner on the north side of the house. A unit operating in the shade uses as much as 10% less electricity than the same one operating in the sun.
- Trees that lose their leaves in the fall give protection from the summer sun and permit winter sunlight to reach and warm your home. Plant trees on the south, east, and/or west sides of your home. Be sure to shade the AC unit. Create a windbreak with evergreen trees and shrubs to stop chilling winds.
