A common question that many homeowners are curious about is just how long will the furnace in their house last? Unfortunately, while this is a frequently asked question, it is also one of the more difficult questions to answer with clarity. There are many different warning signs that contribute to the life and longevity of your home’s furnace. The short and sweet answer is that most furnaces will typically last anywhere from 15-30 years, on average. However, to ensure that your furnace is performing to the best of its ability and lasting awhile, it’s important that you take the necessary and proper steps with furnace maintenance.

Factors That Can Affect How Long Your Furnace Will Last

1. Age of Furnace

It’s important to take into consideration how old your current furnace is already. The older it is, usually in return it has a shorter life remaining. If your furnace is more than 10 years old, you should begin thinking about the possibility of having to purchase a new furnace as the average lifespan is at minimum 15 years.

2. Manufacturer/Make/Model

Yes, the manufacturer along with the make and the model of your furnace can impact the life of the furnace. Some manufacturers pride themselves on producing high-quality parts while others, not so much. It’s important that you do a considerate amount of research on this before deciding to purchase a furnace. It will be worth your money buying the furnace that could be a little more expensive with higher-quality parts if that means it will last you longer.

3. Maintenance Record

It is recommended that you schedule routine maintenance appointments for your furnace to ensure that it is still running well. You should schedule maintenance in the fall from a licensed HVAC company that along with checking the furnace’s performance, thoroughly cleans the system. This adds to the longevity of a furnace.

4. Climate

Depending on where you live and the climate there, it can have a big impact on the life of your furnace. For example, if you live in Michigan where the winters are long and cold, your furnace will be working harder to keep your home heated among the frigid temperatures. On the other hand, if you live in a warmer climate, the opposite will be true.

As you can see, it’s difficult to put an exact number on just how long your furnace will last. However, if you take the proper steps to ensure that your furnace is running well, you can increase the longevity of the furnace. Investing in a new furnace is a huge purchase, therefore it’s important that you make your current furnace last as long as possible.
