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 messing around with all of the new appliances and different spaces. For some homeowners, it also means contemplating 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 should be on the list of potential to-dos. It plays a key role in home comfort, so understanding a little bit more about your system is very beneficial.

As long as they are running without problems, we don’t pay a lot of thought 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 down the road. 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 find out 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 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 for reference. Then head to the manufacturer’s website or search for guidelines on how to determine 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 mean 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 important?

Usually, when you’ve had a furnace about 15 years, it’s time to start searching for a replacement system to help improve efficiency and overall operations. Newer models typically 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 shop for a new furnace. A few 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.
