Everything has an expiration date. When something is important, or expensive, extending its lifespan as much as possible is beneficial and preferable. Do you know the expected lifespan of your furnace? Or what you can do in the meantime to upkeep its functionality and longevity?

How Long Will My Furnace Last?
One question we hear all the time is “how long will my furnace last?”. While this is a difficult question to answer since there are so many factors at play, we can provide you with some information on average furnace lifespans, furnace replacement signs, some ways you can delay the inevitable.

Average Furnace Lifespan
While some furnaces can last over 40 years (extremely rare), the average lifespan of a typical gas furnace is around 15-30 years. As long as you have scheduled yearly furnace maintenance, your furnace should easily last over 15 years.

Should I Replace My Furnace?
When it comes to furnace lifespans, there are simply too many variables to give a definite answer. Speak with a professional to help determine whether you should replace your furnace or not.

Homeowners with furnaces over 15 years old, however, may experience greater savings in the long run by replacing their system rather than continuing to spend more money on repairs. Older furnaces tend to be extremely inefficient and can cost you hundreds of extra dollars on fuel and operating costs.
