How can I determine the age of my furnace?

March 28, 2019

When you move into a new home, there is a lot to take in and consider as you get settled in. You’re figuring out all of the new appliances and different spaces. For some homeowners, it also means contemplating what upgrades or updates need to be made down the road. It may not always be top of mind, but your heating and cooling system needs to be on the list of potential to-dos. It plays a key role in home comfort, so knowing a little bit more about your system is very useful.

As long as they are operating without challenges, we don’t pay a lot of attention to our furnaces. But as soon as it goes out, or causes problems, we absolutely notice. That’s why it’s a worthy idea to find out how old your furnace is. Then you have an understanding of what you might deal with later on. And this doesn’t just pertain to homeowners moving into a new space. Anyone who isn’t certain how old their furnace is should take time and figure it out.

How can you identify how old your furnace is?

Your furnace should have a sticker located someplace on the exterior or interior paneling. If you don’t see a sticker with the model and serial number on the outer panels, find where the paneling opens up and see if it’s located inside that door.

Write down—or take a photo of—the serial number to have on hand. Then go to the manufacturer’s website or search for guidelines on how to figure out the manufacturing date. You could try searching for “find manufacturing date of YOUR BRAND furnace.” The serial number typically provides insight into the age of your system, but it does change among brands. For example, for some brands, the first four numbers represent the year and month it was manufactured. In the photo below, the serial number shows this particular system was made in July 2015.

If you are still having challenges, you can communicate with the manufacturer directly, or contact KDM Service Corporation for support.

Why is the age of your furnace imperative?

Usually, when you’ve had a furnace about 15 years, it’s time to start shopping for a replacement system to help increase efficiency and overall operations. Newer models often have higher energy efficiency ratings and you’ll definitely benefit from the advancements in technology over the recent years.

You don’t have to rely on just the age of your furance, there are other signs that indicate it might be time to shop for a new furnace. Some of these signs include:

  • Increase in energy costs without major adjustments to the thermostat.
  • More regular and costly repairs to fix the furnace.
  • Reduction in home comfort levels—you never seem to feel warm enough.
