Energy Saving Tips

Heating and Cooling

More than 50 percent of annual energy costs come from your home's heating and cooling systems. Check the filters in your air conditioning and heating systems monthly and change them as needed. Vacuum dust and lint from all intakes and outlets. Clean filters allow air to move more freely and systems to work more efficiently.

  1. Heating Recommendations
  2. Cooling Recommendations
  • Set your thermostat at the lowest comfortable temperature. We recommend 68 to 70 degrees Fahrenheit. Every degree above 70 costs an additional 3 percent to 5 percent. For instance, keeping your home at 75 degrees could cost nearly 30 percent more than keeping it at 70.
  • During winter months, health permitting, it's best to lower the thermostat to between 60 to 65 degrees at night. By keeping your thermostat 10 degrees lower at night, you'll ave 10% to 20% in heating costs.
  • With a heat pump, avoid large changes in thermostat settings. A dramatic increase in temperature may cause the supplemental heat strip to operate, forcing energy consumption much higher along with your costs.
  • Change your filter regularly. Dirty filters increase heating and cooling costs.
  • Caulk and weather-strip leaky doors and windows. Insulated or storm windows also help reduce unwanted heat loss.
  • Open drapes on the sunny side (usually south and west) of your house during the day. You'd be surprised how efficiently that sunlight will warm those rooms. Close drapes and shades at night.
  • Make sure drapes and furniture are not blocking air vents or returns.
  • A portable heater may allow you to lower the temperature in the rest of the house, but it can also be expensive if used 24 hours. Use portable heaters in moderation.
  • Turn off kitchen or bathroom exhaust fans when your air conditioning is operating.
  • Keep your central unit fan in the "auto" position. Running the fan 24 hours a day can add as much as $15 a month to your heating costs.
  • Keep the outside heating unit clear and clean.
  • Close the flue when you aren't using your fireplace.

  2. Good Landscaping Saves Money All Year
  • Set your water heater to 120°. Most manufacturers set the temperature at 140°, but many families operate comfortably at 120°. Not only does this save money, it also reduces the risk of hot water scalding.
  • To save additional energy, install a low-flow shower head and limit showers to five minutes.
  • Replace conventional light bulbs with Compact Fluorescent Lamps (CFLs). CFLs use a fraction of the energy that traditional bulbs use and can be found in many stores.
  • Purchase energy efficient products when replacing appliances and heating and cooling systems. Look for ENERGY STAR® products.
