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 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 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 beneficial.

As long as they are running without issues, we don’t pay a lot of attention to our furnaces. But as soon as it goes out, or causes problems, we absolutely 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 in the future. And this doesn’t just apply to 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 establish 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 check if it’s located inside that door.

Write down—or take a photo of—the serial number for reference. Then head to the manufacturer’s website or search for guides 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 differ among brands. For example, for some brands, the first four numbers indicate 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 significant?

Usually, when you’ve had a furnace about 15 years, it’s time to start searching for a replacement system to help increase 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 past several years.

You don’t have to rely on age alone, there are other indications that it might be time to search for a new furnace. A handful of these signs include:

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