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 think about as you get settled in. You’re getting to know 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 learning a little bit more about your system is very useful.

As long as they are running without problems, we don’t pay a lot of attention to our furnaces. But as soon as it goes out, or causes problems, we definitely 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 clear 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 outside, 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 have on hand. Then visit the manufacturer’s website or search for instructions on how to identify 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 mean 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?

Sometimes, when you’ve had a furnace about 15 years, it’s time to start shopping 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 last years.

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

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