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 messing around with 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 must be on the list of potential to-dos. It plays a vital role in home comfort, so understanding a little bit more about your system is very useful.

As long as they are working without issues, we don’t pay a lot of thought to our furnaces. But as soon as it goes out, or causes challenges, we certainly notice. That’s why it’s a good 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 pertain to 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 establish how old your furnace is?

Your furnace should have a sticker located someplace 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 see 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 guidelines on how to identify the manufacturing date. You may 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 represent the year and month it was manufactured. In the photo below, the serial number means this particular system was made in July 2015.

If you are still having challenges, you can reach out to the manufacturer directly, or contact Tokay Heating and Air Conditioning for help.

Why is the age of your furnace significant?

Usually, when you’ve had a furnace about 15 years, it’s time to start looking for a replacement system to help increase 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 how old your equipment is, there are other indications that it might be time to search for a new furnace. Some of these signs include:

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