To keep your home cool with central air conditioning while also optimizing energy efficiency (and therefore cost), keep the temperature at 78 degrees Fahrenheit or higher.
The suggestion comes from Energy Star, a federal program managed jointly by the Department of Energy and the Environmental Protection Agency that provides information to consumers about energy efficiency practices that not only save consumers money, but also improve air quality and protect the environment.
With record-breaking heat waves becoming the norm, finding ways to beat the heat without busting your budget might seem mystifying, which is why Energy Star provided consumers with a set of energy-saving recommendations on how to best manage central air conditioning in warmer spring and summer months.
According to Energy Star, keeping your central air thermostat set to 78 degrees is optimal for both cooling and energy efficiency, but this recommendation only applies to the times when you are home.
While you are away from the house during the day, you should keep the thermostat set to 85 degrees or higher.
While you sleep, Energy Star recommends keeping the temperature set at 82 degrees or higher.
