How old is your Furnace?

Knowing the furnace age is important for a few reasons. First, it’s good to know how long you can expect the unit to last. Second, if you plan on selling your home, the age of your furnace could affect its resale value. Finally, older equipment may need more frequent repairs or maintenance due to normal wear and tear over time.

In general, most furnaces have a life expectancy of approximately 20 years depending on several factors such as quality, usage, and maintenance habits. Some furnaces will run longer but will require some repairs along the way.

How to find it

To find out how old yours is, there are two methods you can use: checking the manufacturer’s data plate or examining the serial number.

The first step is locating the manufacturer’s data plate. This will usually be found on the interior of the unit, either on the side or bottom panel. On older units, it may even be attached to a wall near the furnace. The data plate should include information such as model, serial and manufacturing date.

The second method is examining the serial number itself. Serial numbers are unique identifiers that identify specific furnaces within their brand line. These typically consist of 10-12 characters made up of letters and numbers; for example F1C3N8JA9099.

Sometimes it’s difficult to decipher when your furnace was made just by looking at its serial number, so you might need assistance from an HVAC specialist or manufacturer representative if you’re having difficulty. Or check the Building Intelligence Centre
