How Long Do Furnaces Last?
Most gas furnaces last between 15 and 20 years with proper maintenance, though some run longer and others fail
sooner depending on usage, installation quality, and how consistently they have been serviced. If your furnace is
approaching or past the 15-year mark, it is reasonable to start planning for replacement, even if it is still technically
running.
The "$5,000 Rule" for Furnace Replacement
A simple way to think about repair versus replacement: multiply the age of your furnace by the estimated cost of the
repair. If that number is higher than $5,000, replacement is usually the better financial move. For example, a
12-year-old furnace facing a $450 repair comes out to $5,400, suggesting replacement may make more sense than
sinking more money into an aging system. This is a guideline, not a rigid rule, and we will help you apply it to your
specific situation honestly.
