Heating accounts for the biggest portion of your utility bills.

Check the insulation in your attic, exterior and basement walls, ceilings, floors, and crawl spaces. To determine the insulation R-values in different parts of your home, visit the Air Leaks and Insulation section of energysavers.gov.
Check for air leaks around your walls, ceilings, windows, doors, light and plumbing fixtures, switches, and electrical outlets.
Check for open fireplace dampers.
Make sure your appliances and heating and cooling systems are properly maintained. Check your owner's manuals for the recommended maintenance.
Study your family's lighting needs and look for ways to use controls- like sensors, dimmers, or timers- to reduce lighting use.
