How can I determine the age of my furnace?

March 28, 2019

When you move into a new home, 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 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 issues, we don’t pay a lot of thought to our furnaces. But as soon as it goes out, or causes challenges, 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 identify 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 exterior, 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 keep for your records. Then head to the manufacturer’s website or search for instructions on how to identify the manufacturing date. You may try searching for “find manufacturing date of YOUR BRAND furnace.” The serial number typically 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 means 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 looking 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 recent years.

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

  • Rise 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.
