4. Replace an older furnace with a high-efficiency system.
If your furnace is over 20years old (built before1992) and has a standingpilot, it probably wastes 35
percent of the fuel it uses,and it is probably near theend of its service life.
In this case, in all but thewarmest climates, ACEEE
recommends earlyreplacement with acondensing furnace withannual efficiency of at least90 percent.
