True or False?
When it comes to air conditioning costs, it takes more energy to cool your home back down after using a setback thermostat than it would have taken to maintain a cool temperature all along.
The answer? False!
As heat advisories are issued across our service area, it’s important to know the facts.
The fact is it takes a lot more energy to keep your home cool all day than to cool it back down when you get home from work.
When you raise the temperature on your thermostat on a hot summer day, the air conditioning uses less electricity over that eight-hour period.
In fact, the U.S. Department of Energy recommends setting your thermostat to 88 F while you’re away. The higher interior temperature actually slows the flow of heat into your home, so it won’t take as much energy to cool things back down as you think when you return home. https://www.youtube.com/watch?v=lL4U3EY1VmQ#action=share

In a study of cooling costs by Powerley, people who raised their thermostat:
- 1 degree used 2.4% less energy
- 2 degrees used 4.5% less energy
- 10 degrees used 16.6% less energy
During the workweek, people can save between $0.57 and $4.02 with an air conditioning setback.* From June to the end of September, the savings vary between $16.40 to $68.35
Actual energy savings vary based on the physical characteristics of the home, its size, insulation, thermostat settings and HVAC efficiency, as well as local weather conditions.
