How can I determine the age of my furnace?

When you move into a new home, 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 contemplating what upgrades or updates need to be made later on. 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 learning a little bit more about your system is very valuable.

As long as they are running without challenges, 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 in the future. 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 find out 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 outside, 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 go to the manufacturer’s website or search for guidelines on how to figure out the manufacturing date. You might want to try searching for “find manufacturing date of YOUR BRAND furnace.” The serial number usually provides insight into the age of your system, but it does vary 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 indicates this particular system was made in July 2015.

Why is the age of your furnace imperative?

Typically, 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 tend to 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 signs that indicate it might be time to look for a new furnace. A few of these signs include:

  • Increase 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.
