How Long Do Furnaces Last?

We’re officially in the swing of autumn. This means it’s time for rides through the pumpkin patch and spiced lattes. While you’re enjoying all that fall has to offer, don’t forget to check on your furnace. Fall is the perfect time to schedule an annual maintenance check. You don’t want to wait until it’s too late to service your furnace. Keep reading to discover the average lifespan of a gas furnace, how to extend your furnace’s life span and when it’s time to start looking for a replacement.

Average Lifespan for Gas Furnaces

Estimates for the life expectancy for furnaces vary, but the average lifespan of a typical gas furnace is 15 to 30 years. Although furnaces can last up to 30 years, experts recommend shopping for a new one after the 15-year mark. You don’t have to go out and purchase a new one right away — especially if your current one works fine. But keeping your old furnace can be expensive. Repairs made to furnaces older than 15 years can be costly. Not to mention, you could save 20 percent on energy bills by switching to a newer and more efficient furnace model.

Factors That Age Your Furnace

When determining the lifespan of your furnace, there are a few things to keep in mind. Here are some key factors that cause your furnace to age faster:

Frequency of Maintenance

The frequency and quality of your furnace maintenance can extend its lifespan. That’s why routine fall inspections by a licensed HVAC professional is essential.

Moisture Levels and Ventilation

Too much moisture causes rust and may result in malfunctions. Moisture is also detrimental to your heat exchanger.

Proper Installation

Did you know that over half of all new HVAC systems are improperly installed? Faulty installation results in a 30% efficiency, causes premature breakdowns and reduces air distribution.

Heating Cycles

The way you manage your home’s temperature will have an impact on your furnace’s lifespan. For example, if you keep your home cooler in the winter, when your home is empty, you’ll ease the stress put on your furnace.

Furnace Size

Most homeowners don’t consider the size of their furnace. However, a furnace that is too small or too large for your home will have to cycle more than necessary — this shortens the lifespan of your furnace.

Signs You Need to Replace Your Furnace

The last thing you want is a malfunctioning furnace in the middle of winter. Watching for warning signs can give you a head start on shopping for a replacement. You’ll want to pay attention to the following indicators that your furnace is reaching the end of its lifespan:

Increasing Energy Bills

If you notice a spike in energy bills every year, your old furnace may be to blame.

Uneven Heating

Are some rooms colder than others? This may be an indicator that your furnace is not functioning efficiently.

Poor Air Quality

When your furnace is at the end of its lifespan, it doesn’t properly regulate air quality. You may notice issues with humidity and an increase in dust.
