Top Ten Tips

  1. Set thermostats at 78°F in the summer and 68°F in the winter. You can expect a 3% to 5% increase in energy use for every degree you set the thermostat lower in the summer and higher in the winter. Also consider installing a programmable thermostat.
  2. Properly insulate attic, walls and floors. We recommend R-30 for the attic, R-19 for floors, and R-13 for walls or local building codes, whichever is higher.
  3. Use storm windows or double-paned replacement windows to greatly reduce heat loss in the winter and heat gain in the summer. Storm windows are relatively inexpensive, and they also help decrease the outside noise that enters your home.
  4. Properly seal ductwork. Gaps in joints and at plenums can cause your heating and cooling bills to increase by as much as 30% and can allow air contaminants to enter the home. Sealing with duct mastic is the best way to fix the problem permanently.
  5. Have heating and cooling systems professionally serviced once a year to keep them running as efficiently as possible. If your system is older, consider installing a more efficient system
  6. Check refrigerators and freezers for significant energy loss. Make sure they are as full as possible and that the seals are in good condition. Don't put refrigerators or freezers in unconditioned garages if possible. When buying a new appliance, look for the "ENERGY STAR®" label.
  7. Switch to high efficiency ENERGY STAR® qualified light emitting diode bulbs (LEDs). These bulbs last up to 25 times longer than traditional incandescent bulbs, and they operate at cooler temperatures
  8. Change your filters once a month during the heating and cooling season. If you have pleated filters, change them at least every three months.
  9. Set your water heater temperature to 120° F to save energy and money.
  10. Check caulk and weather stripping around your windows and doors. If the caulk is cracked or the weather-stripping is flat or peeling, replace the old material. Seal other air leakage points around wiring, plumbing attic access and fireplace flues. Use caulk for small holes and expanding foam for larger areas.
