How Long Does a Furnace Last?

TechXpert verified by Ken Kontra

The average lifespan of your furnace is 15 to 18 years. Most furnaces can live a long and healthy life, especially if they’re properly maintained over the years. If your furnace is 15 years old and working well, there’s no need to immediately replace it. But it’s smart to keep a closer eye on it in case it begins to wear out.

Is Age Just a Number?

If your furnace is 15 years old and working well, you may be alright for a few more years. That said, every system has an expiry date, and once your furnace starts giving you more problems than you can count, you won’t want to wait and see how long it can last.

Avoiding a Furnace Burnout

Replacing your furnace isn’t cheap, so you’ll want to schedule regular maintenance checks to keep it in the best condition possible. Caring for your furnace will prevent it (and your wallet) from burning out earlier than expected.
