How can I determine the age of my furnace?

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 seeing 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 critical role in home comfort, so learning a little bit more about your system is very beneficial.

As long as they are operating without problems, we don’t pay a lot of attention to our furnaces. But as soon as it goes out, or causes problems, we certainly 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 later on. And this doesn’t just pertain 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 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 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 visit 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 vary 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.

Why is the age of your furnace imperative?

Usually, 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 typically 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 just the age of your furance, there are other signs that indicate it might be time to look for a new furnace. A few of these signs include:

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