The best thermostat setting for your home depends on many factors, including the time of day, time of year, and what you do. According to the U.S. Department of Energy, the ideal temperature setting for your thermostat when you’re indoors during the winter is 68 degrees. This setup allows you to live comfortably while also conserving energy, reducing your monthly costs in the process.
On the other hand, homeowners should set their thermostats no less than 50 degrees while away for extended periods of time during the cooler months of the year. While 50 degrees seems to be the limit that most HVAC professionals and energy conservation resources agree on, some sources advise homeowners to set their thermostats a few degrees to be on the safe side. The Dominion Service Company recommends setting thermostats at around 55 degrees, while Burnsville Heating and Air Conditioning states to avoid setting thermostats to anything below 60 degrees if you live in a very cold area. Ultimately, homeowners should consider their location, the size of their home, and the amount of time they will be out before setting their thermostats to the temperature they think is most appropriate for their home.
