How can I determine the age of my furnace?

When you move into a new home, there is a lot to take in and consider as you get settled in. You’re messing around with all of the new appliances and different spaces. For some homeowners, it also means seeing 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 vital role in home comfort, so knowing a little bit more about your system is very valuable.

As long as they are working without challenges, 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 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 apply 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 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 keep for your records. Then visit the manufacturer’s website or search for instructions on how to figure out the manufacturing date. You could 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 indicates this particular system was made in July 2015.

If you are still having challenges, you can communicate with the manufacturer directly, or contact Rapids Sheet Metal Works Inc for assistance.

Why is the age of your furnace important?

Usually, when you’ve had a furnace about 15 years, it’s time to start looking for a replacement system to help enhance 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 just the age of your furance, there are other signs that indicate it might be time to look for a new furnace. A handful of these signs include:

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