It depends on how old your furnace is and the cost to get a new furnace. A good rule of thumb is, no matter the age of the furnace, if the cost to repair is 50% of the cost of a new furnace, you should replace it. But for less expensive repairs, you should be less resistant to replacing the furnace the older it is. So if the furnace is 20 years old, and the cost to repair the furnace is only 10% of the cost of a new furnace, you should probably replace it (because itâs more likely to break down again soon).
Furnace Lifespan. The average service life of a new furnace is 15 to 20 years. Most furnace parts that fail during that span are replaceable at a cost that makes repair a better call than replacing the entire furnace. The exception is the heat exchanger, a furnace's single most expensive component.ew air conditioning and heating equipment lasts longer than ever. The end of a furnace's or air conditionerâs service life depends on more than just chronological age. Energy-efficiency issues and the price of any necessary repairs versus the cost of upgrading to a new unit all enter into that determination.
