Seasonal Tips

Heat and Cool for Less this Season

With cooling systems working harder to handle rising temperatures, summer is the ideal time to focus on ways to save energy, and save money on cooling.

  • Set your thermostat on the highest comfortable setting. If you're leaving for the day, turn it up a couple of degrees. Don’t turn your cooling system off unless you'll be gone for an extended period of time. 
  • Clean or change your filters monthly to keep your system running at peak performance.   
  • Use a ceiling fan or portable fan to supplement your air conditioning. A fan can make you feel three to four degrees cooler so you can set your thermostat a few degrees higher and save on cooling costs. Use in occupied rooms since fans cool people, not rooms.
  • Switch your central air conditioning to “auto” for better cooling and humidity control bill versus keeping the system switched "on" continuously.
  • Close blinds, drapes and shades during the hottest part of the day to keep the sun's rays from heating your house. 
  • Promptly repair your air conditioning system if it’s not cooling properly. An inefficient unit can lead to extremely high bills. Plus, you could qualify for a Duke Energy Progress rebate.
  • Closely monitor older air conditioning equipment – especially temperature settings, hours of operation and filter condition.
  • Use your microwave or countertop appliances for cooking instead of the oven or stove.   
  • Properly insulate your home. In existing homes, wall insulation may be too expensive to install, so concentrate on attic and floor insulation. In the Carolinas aim for the following insulation levels:
    • Ceiling: R-30
    • Wall: R-11 to R-19
    • Floor: R-19
