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 at some point. 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 knowing a little bit more about your system is very valuable.

As long as they are operating without challenges, we don’t pay a lot of attention to our furnaces. But as soon as it goes out, or causes issues, we absolutely 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 apply 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 identify 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 see 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 guidelines on how to figure out 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 differ among brands. For example, for some brands, the first four numbers indicate the year and month it was manufactured. In the photo below, the serial number indicates this particular system was made in July 2015.

If you are still having problems, you can call the manufacturer directly, or contact Central Aire Heating & A/C Inc for support.

Why is the age of your furnace significant?

Typically, when you’ve had a furnace about 15 years, it’s time to start shopping 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 how old your equipment is, there are other signs that indicate it might be time to search for a new furnace. Some of these signs include:

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