How Long Does a Furnace Last?

If you want to keep your home comfortable, you need a working furnace. While furnace maintenance can help you stabilize your home’s internal temperature, there may still come the point where maintenance no longer gets the job done. With that in mind, it’s good to know just how long a furnace can serve your home and when it’s time to start looking for a replacement.

Furnace Lifespan: How Long Does Your Furnace Last?

Compared to other units, your furnace’s lifespan varies based on its brand and when it was installed in your home. That said, most gas furnaces can last somewhere between 15 and 20 years with reasonable care. Gas furnaces that are poorly maintained or whose parts fall out of circulation may experience shorter lifespans. 

Similarly, gas furnaces that receive regular upgrades and annual inspections can live beyond this predicted lifespan. However, whether they’ll continue to serve their fitted home adequately depends on additional developments within that home.

What Effects Can Shorten Furnace Lifespan?

Furnace lifespan is most often impacted by any damage and wear and tear your unit undergoes over the years. The effects that tend to have the most profound impact on the length of time your furnace serves your home include:

  • Rusted body essentials
  • Pilot control problems
  • Inefficient heating and cycling
  • Blower damage

To determine what kind of damage has plagued your furnace in the past or is likely to appear in the future, you can consult the team with T.E. Spall & Son. Our experts can help you better understand your furnace’s condition and estimate how long your unit may effectively continue to serve your home.

When Do You Need to Replace Your Furnace?

Determining when to replace your furnace versus when to repair it is a matter of the furnace’s overall condition. You can watch for specific signs that indicate substantial furnace wear and tear, including:

Consistently Decreasing Heat

There can come a point where your furnace may no longer adequately serve your home… well, at least not your whole home. In these cases, your furnace can still produce heat; it can even circulate that heat efficiently. However, your furnace may no longer have the power to keep you and your family comfortable. This condition is most common in homes that have undergone significant renovation since a furnace’s installation. 

Frequent Repairs

Repairing furnace damage now and then isn’t a problem. In fact, it’s one of the things that T.E. Spall & Son does best, and we recommend you get your unit repaired when it’s necessary. However, if you find yourself experiencing near-constant furnace damage, then it may no longer be financially feasible for you to invest in that unit. In fact, it may be more financially wise to shop for a new furnace. 

If you’re not sure whether it’s time to replace or repair your furnace, sit down with a T.E. Spall & Son team member. We can assess the state of your furnace, value it in contrast to your home, and let you know whether additional repairs can help make the unit better serve your home.
