Man doing maintenance on a furnace

How can I determine the age of my furnace?

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 seeing 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 critical role in home comfort, so knowing a little bit more about your system is very useful.

As long as they are operating without problems, we don’t pay a lot of care to our furnaces. But as soon as it goes out, or causes challenges, we definitely notice. That’s why it’s a great idea to find out how old your furnace is. Then you have an understanding of what you might deal with later on. 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 find out 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 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 for reference. Then visit the manufacturer’s website or search for guidelines on how to determine the manufacturing date. You may try searching for “find manufacturing date of YOUR BRAND furnace.” The serial number typically provides insight into the age of your system, but it does vary 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 shows this particular system was made in July 2015.

If you are still having challenges, you can communicate with the manufacturer directly, or contact Keystone Heating & Air Conditioning Co., Inc for support.

Why is the age of your furnace important?

Sometimes, when you’ve had a furnace about 15 years, it’s time to start searching for a replacement system to help enhance efficiency and overall operations. Newer models typically 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 how old your equipment is, there are other signs that indicate it might be time to shop for a new furnace. A few of these signs include:

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