Energy Tips for Air Conditioning

Air conditioning typically accounts for 30-40% of your electric bill. Even a moderate reduction in A/C use could save you big bucks!

  • Turn off the A/C and open the windows.
    Even in South Florida there are some months when it's cool outside.
  • Shut the door - and the windows.
    When you do use your A/C, don't waste the cool air. Double-check that the windows and doors are closed.
  • Seal around doors and windows.
    Caulking and weather-stripping can help to keep the cool air in and the warm air out. Even those tiny cracks can add up to a lot.
  • Fans help us feel cooler.
    A gentle breeze makes our skin feel cooler at almost any temperature. This could mean more days without using the A/C or setting the thermostat a few degrees higher. Don't forget to turn off the fans when you leave the room.
  • Clean or change your filter monthly.
    This can help you and your A/C breathe easier. Reusable filters that can be cleaned and used again will cut down on the cost and trash!
  • Say Aaah!
    Your air conditioner should get a checkup by a professional every year. An inspection and a good cleaning will not only extend the total life of the unit, but could also save you nearly 10-20% on your A/C costs.
  • Set your thermostat to 78F.
    This moderate temperature combines comfort and energy efficiency. Each degree above that can shave an additional 5 - 8% off cooling costs.
    • Switch to an electronic thermostat.
      They can be set more precisely and most are programmable. Set the thermostat a few degrees higher when you plan to be out.
    • Have your A/C ducts checked for leaks.
      Repairing leaks can help your house cool down faster and save you up to 30% on your A/C costs.
    • Trees Trees Trees!
      Plant native shade trees on the east, west and south sides of your house. Mature shade trees can reduce air conditioning costs by 30%. Pay special attention to the A/C compressor outside. Shading the outdoor part of the A/C can lower cooling costs.
    • Keep the sun out.
      Installing awnings or exterior shades is a good option. Installing blinds or curtains on the inside of your windows is a cheaper, but less effective alternative. Remember that light colors absorb less light and help to keep your home cooler.
    • Make sure you have good insulation in the attic.
      A well-insulated attic can reduce the load on the A/C up to 20%.
    • Now if you really want to save: make your roof a reflective white!
      You can achieve huge energy savings (up to 40%) by doing this! The next time you are reroofing or repainting, choose white because this color is more reflective than other colors.
