The best temperature to keep your house at depends on a few factors, such as the season and the weather outside. In general, during the winter months it is best to keep your thermostat set to a temperature between 68 and 72 degrees Fahrenheit. In the summer, a good range to aim for is between 74 and 76 degrees Fahrenheit. However, the most important thing is to keep your home at a temperature that is comfortable for you and your family.
