The #1 Reason Why A Furnace Has to be Replaced

Furnaces get replaced for many reasons but one reason among them all takes the lead by far! The biggest reason why a natural gas or propane furnace has to be replaced is because of a cracked or compromised primary or secondary heat exchanger. Because replacing the heat exchanger is very expensive, most people opt for furnace replacement and get a whole new unit. In this video I take a closer look at the primary and secondary heat exchanger, explain how they work, and point out common failure points.
