If you’ve ever replaced a furnace, you know how big of an investment it can be.

Which is why extending the life of that furnace as long as possible is so important.

Whether you’ve recently installed a new unit or have an old furnace that you’re praying will hold on just a little bit longer, there are a few things you need to know.

Keep reading to find out how long does a furnace last, and a few tips for extending that lifespan as much as you can.

How Long Does a Furnace Last?

How long your furnace may last largely depends on three things; the quality of the furnace you buy, the environment it’s kept it, and how much use it gets.

But while different factors can shorten the lifespan, or extend it most furnaces still have a limit. The average furnace lasts between 15 and 20 years before needing to be replaced.

Plenty of homeowners report keeping a furnace around past that 20-year mark. Usually, that means that their furnace sees less use, or has been impeccably maintained. Homes in regions that experience months and months of cold weather every year might see their furnace last far less time.

No matter the weather in your area, there are a few things that you can do that can help extend your furnace lifespan.

Swap Your Filters

One of the easiest ways to not only extend the life of your furnace as long as possible but also keep it running properly is to change your filters.

Clean filters are a must for a happy, functional furnace. Dirty filters block airflow, impeding the furnaces ability to push warm air out.

If a filter is dirty enough, it can cause the furnace to overheat or cause other damage internally.

Your furnace filters need to be changed every 1 to 3 months. During warmer months when your furnace isn’t being used much, 3 months between changes is enough. But during the winter when your furnace is near-constantly on, your air filters shouldn’t stay on for more than 1 month, max.

Watch Your Humidity

High levels of humidity in the area where your furnace is located can cause rust to form. This can affect your furnace’s function and lead to parts breaking down.

Sealing out moisture can help you protect your furnace and keep it rust-free, helping it last longer.

Lower the Temp While You’re Away

The more your furnace works, the more strain that is put on it. Reducing the amount of time your furnace runs in a day can add up big time, possibly extending the overall lifespan of your furnace.

When you aren’t at home, or you’re warm in your bed at night, dropping your home’s temperature by just 5 degrees will give your furnace a bit of a break.

It’s a common myth that keeping your home at a constant temperature is the best way to save on energy costs. But it won’t cost any more, and could even save you some money to turn your heat down when you’re away from home for work, or at night while you sleep.

Get it Checked Out

Regular maintenance checks can also help you keep your furnace running longer.

During these checks, your technician will check valves, lubricate moving parts, and more. Frequent maintenance can go a long way towards extending the lifespan of your furnace.
