Late summer is when the heat definitely starts to wear on you. It can be tempting to crank the air conditioning to as low as it can possibly go. 

But Energy Star, a joint federal program run by the Department of Energy and the Environmental Protection Agency, have set recommendations for where your thermostat should be for ideal energy efficiency: 

78° F when you’re home 85° F when you’re at work or away 82° F when you’re sleeping

For those who like a cold room while they're asleep, this is definitely a bummer. But according to Energy Star, you'll save 3 percent on your utility bill for every degree you raise the thermostat. 

If you're not that heat tolerant just yet, experiment by raising the temperature up by one degree over a couple weeks until you're used to a warmer home.
