Age and Lifespan: Is Your Furnace Living on Borrowed Time?

Here is the thing: no heating system is designed to last forever The average lifespan of a well-maintained gas furnace is 15 to 20 years, according to Natural Resources Canada If your unit is approaching or has surpassed this milestone, it is officially living on borrowed time Even if it seems to be running fine right now, the internal components are heavily worn and prone to sudden failure.

If you are not sure how old your current system is, checking its age is a straightforward process Follow these simple steps:

1. Locate the cabinet: Go to your furnace and look at the exterior metal casing.
2. Find the metal tag: Search for the manufacturer's identification plate, usually located on the inside of the cabinet door or near the bottom exterior.
3. Check the manufacture date: Look for a clearly printed "MFG Date." If it only shows a serial number, you can usually decode the first four digits (which often represent the week and year) or look up the brand online.
