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 study as you get settled in. You’re getting to know all of the new appliances and different spaces. For some homeowners, it also means contemplating what upgrades or updates need to be made at some point. 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 vital role in home comfort, so knowing a little bit more about your system is very useful.

As long as they are working without issues, we don’t pay a lot of thought to our furnaces. But as soon as it goes out, or causes issues, we certainly notice. That’s why it’s a good 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 affect homeowners moving into a new space. Anyone who isn’t clear how old their furnace is should take time and figure it out.

How can you establish how old your furnace is?

Your furnace should have a sticker located anyplace 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 look if it’s located inside that door.

Write down—or take a photo of—the serial number to keep for your records. Then go to the manufacturer’s website or search for guidelines on how to identify the manufacturing date. You might want to try searching for “find manufacturing date of YOUR BRAND furnace.” The serial number normally provides insight into the age of your system, but it does differ among brands. For example, for some brands, the first four numbers indicate the year and month it was manufactured. In the photo below, the serial number indicates this particular system was made in July 2015.

If you are still having challenges, you can communicate with the manufacturer directly, or contact WM J Kraus & Son for help.

Why is the age of your furnace important?

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

You don’t have to rely on age alone, there are other signs that indicate it might be time to search for a new furnace. A few of these signs include:

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