A furnace is a crucial appliance in homes in Canada, providing warmth and comfort during the colder months. But, like any appliance, a furnace will eventually wear out and need to be replaced. So, how long does a furnace last? Well, there are a variety of variables that can affect the lifespan of a furnace. In this article, we answer your questions about the lifespan of your furnace and what you can do to improve it.
Average Lifespan of a Furnace
The average lifespan of a furnace is 15-20 years. But, this can vary depending on a few factors, including the type of furnace.
This chart illustrates the average lifespan of each type of furnace:
Factors That Affect the Lifespan of Your Furnace
There are other factors that affect the lifespan of your furnace. These include:
- Amount of maintenance
- Frequency of cleaning and filter replacement
- The environment in which it’s used
A furnace that is properly maintained, cleaned, and cared for will last longer than one that’s neglected and left to collect dust. Taking care of a furnace includes scheduling regular maintenance, cleaning, and replacing the furnace filters as required. Doing so can help extend the lifespan of your furnace. On the other hand, neglecting furnace maintenance can lead to premature failure and the need to replace your furnace.
Additionally, a furnace in a home with pets or people with allergies might not last as long and need to be replaced sooner due to increased wear and tear on the filters. Homes with hard water are also tougher on furnaces, as increased corrosion reduces their lifespan.
Signs Your Furnace is Near the End of its Life
As your furnace ages, there are signs to look out for that will indicate it’s near the end of its life.
- Increased energy bills
- Strange noises
- Decrease in heating effectiveness
Before your furnace fails completely, address these symptoms of old age. It could be possible to repair your furnace, but if it’s old and experiencing these issues, it’s time for a replacement. Doing so proactively will save you money.
Ultimately, the lifespan of a furnace can vary depending on the environment and how well it’s cared for. But, on average, furnaces last 15-20 years. Regular maintenance and proper care can serve to extend the life of your furnace while skipping maintenance and ignoring environmental factors can shorten it.
