The recommended thermostat setting for summer is generally around 78 degrees Fahrenheit when you are at home. This temperature strikes a balance between comfort and energy efficiency, helping to keep cooling costs manageable while maintaining a comfortable indoor environment
. When you are away from home, it is advised to raise the thermostat setting to about 80-85 degrees Fahrenheit to save energy and reduce costs, since cooling an empty house is unnecessary
. For sleeping, some sources suggest setting the thermostat slightly lower, around 72-75 degrees, to improve sleep quality while still conserving energy compared to lower daytime settings
. In summary:
- At home during the day: Set thermostat to about 78°F.
- When away from home: Raise thermostat to 80-85°F.
- At night for sleeping: Set thermostat around 72-75°F.
Using programmable or smart thermostats can help automate these adjustments for convenience and further energy savings
. This guidance aligns with recommendations from the U.S. Department of Energy and other energy authorities aiming to optimize comfort and reduce electricity bills during summer
