Life Expectancy of Furnace
We were told our ten year old American Standard furnace's heat exchanger is bad at our last service call. The company sent us an estimate to replace the whole system to the tune of almost $3,000.00 with a Trane system.
After much research it seems to me that a furnace should last longer then ten years. Ours is a natural gas system, and the one that we had replaced was thirteen years old.
Am I being too skeptical regarding the life of this furnace and the amount to replace it?
