If you don’t know how old your furnace is, it’s challenging to know when it’s time for an upgrade.

As your furnace increases with age, especially with a lack of maintenance, it becomes less efficient, causing it to work harder and increase your utility bills. This, combined with record-breaking efficiency on newly-designed systems, you’re likely to get a generous return on your investment by replacing an outdated furnace.

Here are some tips to determine the age of your system:

Pull off the Removable Door

This is usually along the bottom of the front of the unit. Look at the interior of the metal door for a label or tag listing the furnace’s serial number. This may also show an actual manufacturer’s date, depending on the company that made the furnace.

Look at the Serial Number

The first two digits can be the week of the year that the unit was manufactured, with the third and fourth number indicating the year. A serial number starting with 0298, for example, may have been made the second week of 1998.

Look for a Service Sticker or Tag

This is usually common on gas furnaces and may list the date that the furnace was installed. This can often give a close approximation of the unit’s age.
