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?
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.
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.
Here are some factors that will affect how long your furnace will last:
As you can see, many factors play a role in how long your furnace will last. No one thing will be able to tell you how long your furnace will last (age, tune-ups, humidity levels, installation).
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.
According to the U.S. Department of Energy, homeowners can expect a good return on investment by replacing a furnace with an annual fuel utilization efficiency (AFUE) rating lower than 80% with a new 95% efficient condensing furnace.
Upgrading a furnace that is older than 15 years old with a new high-efficiency unit is a great way to save money and increase home comfort and efficiency. High-efficiency furnaces have an AFUE rating between 90% and 99%, condensing flue gases to a second heat exchanger to reduce the amount of wasted energy. This helps convert nearly all of the fuel to useful heat for your home.
One common rule that people follow when it comes to repairing or replacing something is the 50% Rule — if the repair is over 50% of the cost for a full replacement, go with the replacement.
