Wouldn’t it be lovely if your furnace just lasted forever? Unfortunately, there will come a time when it needs to be replaced. If you have a gas furnace, that will happen after about 15 years, and if you have an electric furnace, you can hope for about 20.
Keep in mind, though, that these estimates are based on furnaces which receive maintenance annually. Furnaces that don’t receive maintenance might last half as long.

What can you do to keep your older furnace running for as long as possible? We’ve got three tips that can help a whole lot.
