Find the Leaks, Then Weatherize
You can save 10% or more on your energy bill by reducing the air leaks in your home.
  • Test your home for air leaks. On a windy day, hold a lit incense stick next to the common sources of air leaks shown below. If the smoke travels horizontally, you have found an air leak that may need caulking, sealing, or weatherstripping.
  • Pay particular attention to air leaks at doors, windows, and places where plumbing, ducting, or electrical wiring penetrates through exterior walls, floors, ceilings, and soffits over cabinets.
  • For a more accurate measurement of air leakage, hire a technician to conduct a blower door test in your home.

Don't Lose Energy out the Window
Windows add to the ambiance of the home but they can waste a lot of energy.
  • Close your curtains and shades at night; open them during the day.
  • Tape clear plastic sheeting to the inside of your window frames if drafts, water condensation, and frost are present.
  • Install tight-fitting, insulating window shades on windows that feel drafty after weatherizing.

Insulate Against High Bills
Installing a programmable thermostat is an excellent way to cut your heating bills.
  • Insulate your hot water heater and hot water pipes. Follow the manufacturer's instructions or get professional help.
  • Check the insulation in your attic, ceilings, exterior and basement walls, floors, and crawlspaces to see if it meets the levels recommended for your area.
  • For insulation levels specific to your location, visit the DOE Zip-Code Insulation Program.

Control Your Temperature
Windows add to the ambiance of the home but they can waste a lot of energy.
  • A programmable thermostat can be pre-set to lower the temperature when you're sleeping or at work. The energy savings will offset the cost of a basic unit in less than a year.
  • Lower your thermostat from 72° to 65° for eight hours a day to save up to 10% on your heating bill.
  • Regularly clean or replace furnace air filters, follow the manufacturer's maintenance schedule, and don't block the registers.

Heating and cooling are a big part of a typical home's energy expenses.
Don't Forget Your Ducts
Even though you can't see them, your ducts may be wasting money.
  • Check your ducts for air leaks. First look for sections that have separated and then look for obvious holes.
  • Insulating ducts in unconditioned spaces is usually very cost effective.
  • Ducts are a hidden savings opportunity. See Improving the Efficiency of Your Duct System for more information.
Dollar SignLong-Term Savings Tip — You can lose up to 60% of your heated air before it reaches the register if your ducts aren't insulated and they travel through unheated spaces such as the attic or crawlspace. Get a qualified professional to help you insulate and repair ducts.
