How Long Does a Furnace Last? 

When a furnace is properly cared for, it can last up to 20 years on average. However, this lifespan is dependent upon proper care of your furnace and making any repairs it needs in a timely manner.

Yet, even this number is subjective. There are other things that can cause your furnace to last for a smaller amount of time. If you know your furnace is creeping up in age, it’s time for you to start shopping around for a new one!

Factors That Impact Furnace Life Expectancy

There are a few things that play a role in how long your furnace will last you. Below, we’ll talk about what may impact the length of time your furnace lasts.

Size Of Your Furnace

If your furnace isn’t properly sized for your home, it’ll drastically impact the life expectancy of your furnace. For example, if your furnace is too big for your home, it can cause the furnace to not last as long as it should. This is because it’ll constantly turn off and on, creating more wear and tear on the parts of the furnace.

On the other hand, if the furnace is too small, it’ll stay on for too long. This can cause the furnace to have an additional strain on the system, causing it to last for a shorter period of time. 

Your Thermostat

If your thermostat doesn’t have the best settings, it can cause additional wear and tear on your furnace. For example, if you have your home set to be too warm in the winter, it can cause the furnace to work overtime. 

You should aim to keep your home set around 68 degrees Fahrenheit all year around. This will ensure the system doesn’t have to work too hard to keep your home too warm in the winter. 

Lengthening The Lifespan of Your Furnace

So, if you were wondering, “how long does a furnace last?”, the answer is around 15 to 20 years. You can extend the lifespan of your furnace if you take proper care of it. By having regular maintenance performed on your furnace, it’ll ensure that everything is working the way it should be in the system.
