Purchasing an older home with an existing furnace can be a worry; a furnace often needs replacing after 15 to 20 years, so knowing its age is helpful in determining if a new furnace should be in the budget.

Newer units may have a manufacturer's date listed somewhere on the furnace; older furnaces require a bit more digging by looking at the serial number, which tells the manufacturer various pieces of information, including the age. Finding the serial number, however, may also require a bit of sleuth work. Pull off the removable door on the outside of your furnace; 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. Turn off the power to the furnace -- by either turning off the power switch or the master fuse to the unit -- and look at the fan and fan blades.
