• Clean and maintain your furnace annually. Replace or clean filters in a hot air system or heat pump monthly.
  • If you are replacing your AC unit, make sure you replace it with a high efficiency heat pump with a SEER (seasonal energy efficiency ratio) of 13 or better.
  • If you have an inefficient furnace, consider adding a high-efficiency heat pump. It could save you up to 40% on heating costs and keep you cool next summer.
  • When the heat is on, turn the thermostat to the lowest setting comfortable to your family and leave it. Especially with a heat pump, vary the setting no more than three-to-five degrees from day to night to heat efficiently.
  • Don't block conditioning vents with furniture or clutter. Keep them clean.
    In the winter, close drapes at night and let the sun in during the day to cut energy costs.
