Raise the temperature slowly to keep your bill lower. Quickly raising your temperature set point activates the heat strip, which uses tons of energy.
Set your thermostat to 68-70 degrees during the day in the winter, and 65-68 degrees at night to keep your home comfortable and save on heating costs.
Set your thermostat to 78-80 degrees during the day in the summer, and 80-82 degrees at night to save on cooling costs.
Lower your thermostat every time you leave the house.
Close your exterior doors and windows when the heating or AC is on.
Use ceiling fans or floor fans to cool off for less.
Switch your ceiling fan to turn in a counter-clockwise direction in the summer; in the winter, run it at low speed, but clockwise. Ceiling fans use no more electricity than a standard light bulb. However, be sure to turn fans off when you leave - they only cool people, not rooms.
