What Atmos energy does, it puts heat in your house. Atmos energy is gas that is heat. I learned you have to close the window, if you don't close the window, your bill will go high. If you are going outside make sure you turn off the t.v. When I had to smell a card it smelled like gas. If you're out of the house make sure you put the thermostat on 65 degress. Make sure you don't leave the hot water on. If you don't turn off your lights your bill will go high,make sure to turn off your lights,and make sure your water doesn't leak.
