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 contemplating what upgrades or updates need to be made later on. 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 learning a little bit more about your system is very beneficial.

As long as they are working without problems, we don’t pay a lot of attention to our furnaces. But as soon as it goes out, or causes problems, we certainly 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 later on. And this doesn’t just affect 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 anyplace 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 check 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 instructions on how to identify 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 change 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 shows this particular system was made in July 2015.

If you are still having issues, you can call the manufacturer directly, or contact Controlled Comfort HVAC Inc for assistance.

Why is the age of your furnace significant?

Usually, when you’ve had a furnace about 15 years, it’s time to start shopping 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 recent years.

You don’t have to rely on age alone, there are other signs that indicate it might be time to shop for a new furnace. A handful of these signs include:

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