Setting a Thermostat
No two thermostats are alike when it comes to programming, but there are a few rules everyone should know. First, the U.S. Department of Energy recommends setting your thermostat to 68 degrees in winter and 78 in summer for optimal energy efficiency. If you live in a cold climate where pipes can freeze, make sure the temperature is always at least 55 degrees inside the house; in warm, humid climates, don’t bump up any higher than 80 degrees while you’re away from home. The air conditioner needs to run periodically to dehumidify air — you don’t want to come home from vacation to a mold problem.
