Energy Efficiency

Ways To Make Your Home More Energy Efficient


Air Infiltration

  • Tighten and weather-strip old windows and then add storm windows.
  • Seal around pipe penetration coming through walls.
  • When your fireplace is not operating, its flue should be closed tightly, with a sign hanging from the flue handle warning it is closed.
  • Drop-down, disappearing stairways should fit tightly into the ceiling and be carefully weather stripped.
  • Whole-house attic fans should be sealed tightly during the winter.

Water Heaters

  • Make sure your water heater is set at the lowest point. Try setting it to 120º.
  • Try washing clothes with warm water and rinsing with cold water.
  • Overfilling your washer can increase your energy use.
  • If your water heater is located in an unconditioned space, install a thermal wrap around it. Take care to install it in accordance with the tank and wrap manufacturers' instructions.


  • Don't over-dry your clothes. If 50 minutes works, don't set it to 70 minutes.
  • Make sure to clean the inside lint filter before each drying cycle.
  • Periodically check your flexible metal dryer vent hose to ensure it is still tightly connected and not kinked.


  • Make sure refrigerator and freezer seals fit tightly when doors close.
  • Keep outside coils clean. Dirty coils make your refrigerator compressor work longer to remove heat.
  • Setting your freezer below 0º uses extra energy.
  • Setting your refrigerator below 37º uses extra energy.

Heating & Air Conditioning

  • Try to keep your thermostat at 68º in the winter and 75º in the summer.
  • Heating & cooling systems should be checked to verify they are moving the correct amount of air. An HVAC technician can tell you if it is.
  • Heat pump and air conditioning systems should be checked annually to verify they are properly charged, strictly in accordance with manufacturers' guidelines.
  • Inside and outside coils should be kept clean and free of debris.
  • Gas furnaces should be tuned for maximum combustion efficiency.
  • Return filters should be changed monthly.
  • Have an HVAC technician check carefully for duct leaks. Leaks that are found should be sealed with fiberglass mesh and mastic sealant.


  • Don't leave on unnecessary lights
  • Replace incandescent bulbs with energy-saving compact fluorescent lamps (CFLs). They use a fraction of the wattage, last much longer and give off less heat.
  • When you finish cooking, turn off the kitchen lighting and the range exhaust fan.
