The best thermostat settings are 68 degrees Fahrenheit in the winter and 78 degrees Fahrenheit in the summer, according to EPA guidelines. These temperature settings give consumers energy efficiency and affordability while ensuring comfort.
It is easy to save energy throughout the winter by keeping the thermostat at 68 F during waking hours and then lowering it when away from home or asleep. By lowering the thermostat by 10 or 15 degrees for eight hours, a homeowner can save up to 15 percent off of the annual heating bill. During the summer months, the thermostat set at 78 F, then raised when the home is unoccupied, brings a similar positive effect.
For homeowners seeking out the ideal temperature in the home with little effort, the investment into a programmable thermostat may be worth it. A programmable thermostat allows a homeowner to set the temperature in the home based on a schedule. This means in the winter, the temperature may be set at 68 F during waking hours, but at night, it automatically goes down to 58 F. These thermostats may also store and repeat settings based on the day or time. The homeowner can also override any of these settings in order to improve the comfort level of the home.
