A programmable thermostat
can save you up to $150 per year.

6 Smart Ideas for Your Heating System

11. Maintain your equipment. Dirt and neglect are the most common causes of equipment failure. So clean or change the furnace filter once a month (or as often as recommended by the filter manufacturer).

12. Make informed choices. Call your local utility and ask what programs are available to encourage energy efficiency (such as rebates on new furnaces).

13. Get a professional opinion. Schedule a checkup of your heating system with a licensed contractor.

14. Install a programmable thermostat. Used properly, this little gadget can save you as much as $150 a year in energy costs. How? By scaling the temperature down when you're away and scaling it back up when you return.

15. Use less energy heating water. Set your water heater temperature to no more than 120 degrees.

16. Invest in new technology. Replace your refrigerator or water heater if either is more than 10 years old. Replace your heating and cooling system if it's old and inefficient. Buy energy-efficient windows and exterior doors. Over a period of years, the energy savings will help make up for the purchase prices.
