Here are some easy tips and interesting facts to help maximize the heating and cooling energy savings in your home.

Ceiling Fans

  • • Decrease your AC use in the summer by switching to ceiling fans.
  • • Install an Energy Star®-Qualified ceiling fan with lights which are about 50% more efficient than conventional fan/light units and can save you more than $15 per year in energy costs.
  • • Turn off your ceiling fan when you are not in a room, since ceiling fans cool you, not the room.
  • • To save on heating costs in the winter, adjust ceiling fans so they spin clockwise and push hot air down into the room.

Room Air Conditioners

  • • Energy Star®-Qualified room air conditioners use at least 10% less energy over standard models.
  • • Use the appropriate sized model for the room/space that the unit is meant to cool.

Dehumidifiers

  • • Pick the right size dehumidifier for the space/room you are using it in.
  • • Don't overuse your dehumidifier. The comfortable relative humidity for a room is around 35-55%.
  • • Energy Star®-Qualified dehumidifiers remove the same amount of moisture as a similarly-sized standard unit, but uses 10-20 percent less energy. A 40-pint Energy Star®-Qualified dehumidifier can save consumers $28 per year over the life of the unit, that's more than $300 in savings!

Air Purifiers

  • • Energy Star®-Qualified room air cleaners use 45% less energy to remove particles, such as dust and pollen, from the air than standard models saving consumers $35 annually on their utility bills.

Programmable Thermostats

  • • ENERGY STAR® qualified programmable thermostats allow for pre-set energy savings programs that automatically adjust your home's temperature settings, allowing you to save energy while you're away or sleeping.
  • • Follow proper use guidelines to help keep your home comfortable and save you money.
  • • Keep the temperature set at the energy saving set points when no one is home or through the night (periods of at least 8 hours).
  • • Don't consistently override the pre-programmed settings, which results in more energy use and higher utility bills.
  • • Be sure to set your thermostat on an efficient “hold” or “vacation” setting when going away for a few days. Choose a setting several degrees warmer in the summer and several degrees cooler in the winter.
  • • Cranking your unit up to 90 degrees or down to 40 degrees does not heat or cool your house any faster.
  • • Install your thermostat on an interior wall, away from heating or cooling vents.
  • • If your home has multiple heating or cooling zones, use an ENERGY STAR® programmable thermostat for each zone to maximize comfort and savings.
  • • With proper use, installing an Energy Star®-Qualified programmable thermostat can save about $150 every year in energy costs.
