According to Consumer Reports, people with a central air conditioning system can save 3 percent on air costs for every degree the temperature is raised.
Energy Star says for optimal cooling and energy efficiency, the coolest you should keep the house is 78 degrees.
The company recommends the thermostat be set on 82 when it is time to go to bed, and 85 when away or at work.
A programmable thermostat makes hands-free, scheduled adjustments very easy, but it can still take hours for a house to cool down.
To find that perfect temperature, Consumer Reports recommends raising or lowering the temperature one degree at a time, to see how you do and how it may impact your budget.
Experts also recommend getting a fan. Whether it is a ceiling or floor fan, it creates a wind chill effect that helps you feel more comfortable at a higher room temperature.
