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 consider 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 key role in home comfort, so understanding a little bit more about your system is very valuable.

As long as they are operating without problems, we don’t pay a lot of thought to our furnaces. But as soon as it goes out, or causes issues, we definitely 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 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 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 outer panels, 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 visit the manufacturer’s website or search for guides on how to figure out the manufacturing date. You may 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 differ 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.

If you are still having issues, you can reach out to the manufacturer directly, or contact Davis Heating & Air Conditioning for assistance.

Why is the age of your furnace significant?

Typically, when you’ve had a furnace about 15 years, it’s time to start looking for a replacement system to help improve efficiency and overall operations. Newer models often 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 how old your equipment is, there are other indications that it might be time to look for a new furnace. A handful of these signs include:

  • Increase 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.
