How can I determine the age of my furnace?

March 28, 2019

When you move into a new house, there is a lot to take in and think about as you get settled in. You’re messing around with 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 critical role in home comfort, so understanding a little bit more about your system is very beneficial.

As long as they are working without problems, we don’t pay a lot of thought to our furnaces. But as soon as it goes out, or causes challenges, we definitely notice. That’s why it’s a great idea to find out how old your furnace is. Then you have an understanding of what you might deal with down the road. And this doesn’t just apply to homeowners moving into a new space. Anyone who isn’t sure how old their furnace is should take time and figure it out.

How can you find out how old your furnace is?

Your furnace should have a sticker located somewhere 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 have on hand. Then go to the manufacturer’s website or search for guides 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 mean the year and month it was manufactured. In the photo below, the serial number means this particular system was made in July 2015.

Why is the age of your furnace imperative?

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 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 shop for a new furnace. A few of these signs include:

  • Surge 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.
