2. Get your heating and cooling systems checked once a year. A licensed professional will make sure that each is operating efficiently and safely. Checkups can identify problems early.

3. Install your storm windows in the winter, if you have them. Add them if you don’t have insulated windows.

4. Caulk and weather-strip all leaky windows, baseboards and doors.

5. Caulk and weather proof all exterior openings for plumbing, and electrical service and look for other openings that need to be sealed.

6. Make sure all attic vents and ducts are properly sealed. Sealing your ducts can save up to $140 annually on energy bills and help you consistently heat every room.

7. Check your attic and all accessible exterior walls in your basement or unfinished rooms to make sure they are well insulated.

8. Install a programmable thermostat--a system that automatically adjusts to different temperature programs to meet your comfort needs efficiently during different times of the day or week. A programmable thermostat can save you $100 a year when programmed and used properly.

9. Replace traditional light bulbs and fixtures with compact fluorescents. They cost a bit more, but they use two-thirds less energy and can last up to ten times longer than incandescent. They are especially good in high use areas like the kitchen or hard to reach fixtures.

10. Look for products that meet strict energy efficiency criteria set by the U.S. Environmental Protection Agency and U.S. Department of Energy. They use less energy, help prevent air pollution and reduce energy costs in your home.
