Keep Your Cool. In the heat of summer it is tempting to crank up the AC and inevitably, your electric bill. Instead, try opening windows and using fans in the cool of the morning and evening. During the day, close windows and blinds to keep excess sunlight from heating up your home. If you still can’t beat the heat, only use the air conditioner in one, closed off room, as opposed to cooling the whole house.
