Don’t work alone
Team up your air conditioner with a ceiling fan to spread cool air throughout the room. Using both at the same time lets you raise the air conditioner temperature by five degrees, which in turn lowers your cooling costs. You’ll also want to make sure your fan is moving clockwise and pushing the cold air down. Here are sneaky ways to save on every household bill.
Stick with the program
Install a programmable thermostat for your air conditioner and cut down on your utility bill. Set it for several degrees warmer at night or when no one is home; you can save up to 10 percent on your cooling costs for every degree above 78 you raise the thermostat.
Don’t light up your thermostat
Keep heat-generating appliances like lamps, computers, and televisions away from your air-conditioning thermostat. Their heat will trick the air conditioner into running longer. Try these 13 clever ways to slash your energy bill.
