What Will You Save? Although highly efficient gas furnaces typically cost $500 to $1,000 more than less-efficient models, they will easily make up the difference in fuel savings because they’re up to 15 percent more efficient. To calculate your potential cost savings, check out the savings calculator (the calculator is in the right column under “Consumers.”) You also can calculate return on investment through the American Council for an Energy-Efficient Economy. (Costs are national averages and do not include sales tax.)
Go Green!
If your home is heated by a forced-air system, it’s a good idea to hire an energy auditor to test for leaks in your ducts. Leaky ducts can lose up to 35 percent of the hot air produced by a furnace. You can seal the ducts with mastic or hire a professional to do the job for you.
According to the U.S. Environmental Protection Agency (EPA), dirt and neglect are the main causes of heating system inefficiency and failure. To prevent problems and lower heating costs, the EPA recommends periodic professional servicing of your system. Also clean or replace air filters in forced-air systems every month or two during the heating and cooling seasons.
