How can I determine the age of my furnace?

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 considering what upgrades or updates need to be made down the road. It may not always be top of mind, but your heating and cooling system needs to 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 useful.

As long as they are operating without issues, we don’t pay a lot of care to our furnaces. But as soon as it goes out, or causes problems, 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 down the road. 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 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 to keep for your records. Then head to 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 usually provides insight into the age of your system, but it does change 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 indicates this particular system was made in July 2015.

If you are still having challenges, you can communicate with the manufacturer directly, or contact Temp Air System Inc 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 searching 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 indications that it might be time to search for a new furnace. Some 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.
