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 seeing 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 key role in home comfort, so knowing a little bit more about your system is very valuable.

As long as they are working without challenges, we don’t pay a lot of thought to our furnaces. But as soon as it goes out, or causes challenges, 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 in the future. And this doesn’t just apply 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 outside, find where the paneling opens up and check if it’s located inside that door.

Write down—or take a photo of—the serial number for reference. Then visit the manufacturer’s website or search for instructions on how to figure out the manufacturing date. You could 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 vary 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 means this particular system was made in July 2015.

If you are still having problems, you can reach out to the manufacturer directly, or contact Central Heating & Plumbing for assistance.

Why is the age of your furnace significant?

Usually, when you’ve had a furnace about 15 years, it’s time to start looking 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 last years.

You don’t have to rely on how old your equipment is, there are other factors that show it might be time to look 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.
  • Decline in home comfort levels—you never seem to feel warm enough.
