Thermostat settings that save money

A few degrees, at the right times, makes the biggest difference.

5 min read

Heating and cooling are usually the largest part of a home energy bill. Adjusting the thermostat while you're asleep or away is the simplest way to lower it.

Starting points

  • Winter: around 68°F while you're awake at home, and lower while you're asleep or away
  • Summer: around 78°F while you're home, and higher while you're away
  • The US Department of Energy estimates you can save up to about 10% a year by turning the thermostat back 7 to 10°F for 8 hours a day

Make it automatic

  • Use the schedule on a programmable or smart thermostat
  • Set it once for weekdays and weekends
  • Heat pumps work best with small setbacks; check the manual

Comfort without the bill

  • Ceiling fans let you raise the cooling setting a few degrees; turn them off when you leave the room
  • Close curtains on hot afternoons and open them to winter sun
  • Wear layers indoors in winter
