How warm should I keep my home?

Your family could save as much as 10 percent a year on heating and air conditioning simply by turning your thermostats back by 7 to 10 degrees.

The U.S. Department of Energy says lowering the heat in the winter for eight hours a day will do the trick. Same goes for raising the temperature a few degrees for eight hours on summer days.

If you turn the heat down a bit before bedtime, for example, you could see those savings. Then, turn it back up when you get up and then back down again just as everyone leaves the house for school and work in the morning.

Or invest in a programmable thermostat, which will automatically turn the heat up and down at the times you set. Then, you won’t have to worry about forgetting to change the temperature several times a day.
