How can I determine the age of my furnace?

When you move into a new home, there is a lot to take in and consider 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 later on. It may not always be top of mind, but your heating and cooling system must be on the list of potential to-dos. It plays a key role in home comfort, so learning 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 issues, 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 later on. And this doesn’t just affect 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 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 outside, 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 head to the manufacturer’s website or search for instructions 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 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 shows this particular system was made in July 2015.

If you are still having issues, you can call the manufacturer directly, or contact Jett's Heating & Air Inc. for help.

Why is the age of your furnace significant?

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 last years.

You don’t have to rely on age alone, there are other factors that show it might be time to shop for a new furnace. Some of these signs include:

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