Tips for lowering cooling costs in your home

August 01, 2014

For Immediate Release:

Continuous cooling during the dog days of summer can take a bite out of your budget. You can reduce air conditioning energy use by 20-50 percent by switching to a high-efficiency, ENERGY STAR-qualified air conditioner and taking other actions to lower your home’s cooling costs. The U.S. Department of Energy (DOE) offers a home cooling infographic that informs consumers about air conditioning systems and provides the following tips to lower cooling costs:

  • Install and set a programmable thermostat—it could help you save 10 percent on cooling and heating costs each year.
  • Use fans. A ceiling fan will allow you to raise the thermostat setting about 4 degrees without impacting comfort.
  • Insulate your attic and walls, and seal air leaks to prevent warm air from leaking into your home.
  • Insulate and seal ducts—air loss through ducts can account for about 30 percent of a cooling system’s energy use.
  • On hot days, use a microwave instead of an oven to cook; ovens take longer to cook and can make your house warmer, requiring more of your AC system.
  • Install energy-efficient window coverings that let natural light in and prevent solar heat gain.
  • Use a bathroom fan when taking a shower or bath and a range hood when cooking; this helps remove heat and humidity from your home.
