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.
Step by step:
  • Set your "home occupied" temperature to 78°F in the summer. When you are awake and at home, the U.S. Department of Energy suggests setting your thermostat no lower than 78°F for cooling.
  • Set your "away from home" temperature. When you are away from home, set the thermostat to an energy-saving level. Setting the temperature at least 5-8°F higher 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 have separate thermostats on different floors or in different areas, adjust the thermostat to avoid wasting energy in the area you are not using.

Go the extra mile: Consider installing a programmable or smart thermostat for added convenience. Thermostats with adaptive recovery can keep track of seasons, maintain your programmed schedule more closely, and maximize savings. Others can learn your schedule without being programmed at all and can make suggestions about how you can save energy.

Many smart thermostats are also compatible with voice-activated virtual assistants.
