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 study 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 at some point. It may not always be top of mind, but your heating and cooling system must 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 useful.

As long as they are operating without challenges, we don’t pay a lot of thought to our furnaces. But as soon as it goes out, or causes issues, we absolutely 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 down the road. 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 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 outer panels, 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 to have on hand. Then head to the manufacturer’s website or search for instructions on how to identify the manufacturing date. You might want to 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 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 problems, you can communicate with the manufacturer directly, or contact Allstar 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 searching for a replacement system to help increase efficiency and overall operations. Newer models often 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 factors that show it might be time to shop for a new furnace. Some of these signs include:

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