To save the most energy, set your thermostat as low as is comfortable in winter and as high as is comfortable in summer—typically 68°F (20°C) in winter and 78°F (26°C) in summer when you are home. Lower (in winter) or raise (in summer) the temperature by 7-10°F (4-6°C) when you are asleep or away for several hours. Using a programmable or smart thermostat can help automate these adjustments for maximum savings.
