Probably not. Some people believe that setting the AC or even just the fan to run constantly will help them save on electricity. This is not true. If you can run your AC less often, you are more likely to save money. According to the U.S. Department of Energy, you can potentially save 10% on your electricity bill if you diligently set your thermostat 7-10 degrees away from your ideal temperature for 8 hours a day.4 That means, if it's summertime and you prefer your home at 72°F, you should turn the thermostat up to 80°F while you're away at work. 4U.S. Department of Energy https://energy.gov/energysaver/thermostats
