Set your thermostat to 78°F in the summer

Why? You can save up to 10% a year on heating and cooling by simply turning your thermostat back 7-10°F for eight hours a day from its normal setting.
  • Set your "home occupied" temperature. When you are awake and at home, APS suggests setting your thermostat to 79°F.
  • Set your "away from home" temperature. When you are away from home or sleeping, set the thermostat to an energy-saving level — 5°F higher in the summer is a good rule of thumb.
  • Stay comfortable. Use a fan to stay cool in warmer months.
  • Only cool the zones you occupy. If you separate thermostats on different floors or in different areas, adjust the thermostat for energy savings in the area you are not using.
  • Program it. Consider installing a programmable thermostat for added convenience.
