How can I determine the age of my furnace?

March 28, 2019

When you move into a new residence, there is a lot to take in and think about 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 at some point. It may not always be top of mind, but your heating and cooling system should be on the list of potential to-dos. It plays a vital role in home comfort, so understanding a little bit more about your system is very valuable.

As long as they are running without problems, we don’t pay a lot of attention 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 in the future. And this doesn’t just apply to 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 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 exterior, 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 for reference. Then head to the manufacturer’s website or search for guidelines on how to determine the manufacturing date. You might want to 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 mean 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 issues, you can reach out to the manufacturer directly, or contact Colvin's Heating and Cooling for support.

Why is the age of your furnace important?

Typically, when you’ve had a furnace about 15 years, it’s time to start searching for a replacement system to help enhance efficiency and overall operations. Newer models typically 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 age alone, there are other factors that show it might be time to search for a new furnace. A few of these signs include:

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