Keeping Things Cool

Reduce energy usage and manage costs during hot weather months


Summer is upon us. Higher temperatures can trigger increased energy use and result in higher than normal bills.

Here are some simple ways you can stay cooler—and help lower your energy usage

  • Using a ceiling fan while you're home and running the air conditioner will allow you to raise your thermostat setting about four degrees Fahrenheit.
  • Allow cooler air from the morning or night before to flow into your home. As the temperature rises, close the windows and draw the shades to keep pre-cooled air inside.
  • Check the filter on your heating, ventilation and air conditioning system. A dirty filter can cause your system to work harder to keep you cool, wasting energy.
  • If possible, enjoy an afternoon out—at the pool, movies, park or local library.

No-Cost Ideas

  • If possible, move the air conditioning unit to a north-facing or shaded window, as direct sunlight reduces your unit’s efficiency. Provide shading for your air conditioning unit.
  • Use exterior shading devices or plants to shade your home and windows from the sun.
  • Fill up the fridge. Having lots of food in your fridge keeps it from warming up too fast when the door is open. Then it doesn't have to work as hard to stay cool.
  • Turn off lights when not needed.
  • Make sure that connections at vents and registers are well-sealed where they meet floors, walls, and ceilings. These are common locations to find leaks and disconnected ductwork.
  • Use the bathroom fan to remove the heat and humidity from your home after showering or bathing. Make sure bathroom and kitchen fans are vented to the outside and not just to the attic.
  • Unplug electronic devices and chargers when they aren't in use. Most new electronics use electricity even when switched "off."
  • Turn computers and printers off at the power strip.
  • Give your refrigerator breathing room: clean the coils and don’t set the temperature too low. The refrigerator should be kept between 38 degrees and 42 degrees Fahrenheit, and the freezer between 0 degrees and 5 degrees Fahrenheit.
  • Clean the lint from the clothes dryer after every load. Run full loads and use the moisture-sensing setting.

Low-Cost Fixes

  • Consider replacing pool pumps and motors with energy-efficient equipment. If your pool has a filter and automatic cleaning sweep, shorten the operating time.
  • Save energy and money by using pool covers.
  • Remember to have your HVAC system serviced annually to ensure it’s running at optimum efficiency for money and energy savings.
  • Seal your air ducts using mastic sealant or metal and insulate all the ducts you can access. In typical houses, about 20% of the air that moves through the duct system is lost due to leaks, holes and poorly connected ducts.
  • Add insulation to your attic to keep cool air in.
  • Buy an ENERGY STAR® air conditioner if your air conditioner is ready to be replaced and reduce energy usage.
  • ENERGY STAR windows can make your house more comfortable year-round and save you money as well.
  • Consider installing a whole house fan. A whole house fan placed in your attic draws cooler air into the home and forces hot air out through attic vents. Use it when the air is cool outside, such as in the early morning.
  • Install a door sweep on your garage door to seal the gap between the bottom of your door and the threshold. This prevents warm air from coming in and cool air from escaping your home.
