Most Expensive Part of the Furnace to Fix

What are the three most expensive parts to replace in a furnace?

•    The heat exchanger: Where the fuel fires it up and burns to the center of it, and the air from the house circulates the outer surfaces. 

But, we have to exhaust that combustion products for moisture and carbon monoxide. We want to get rid of it, and if its is ever compromised and that heat exchangers split, crack, and have the potential to leak into the house. That way, we'll have to replace the burners and engine.

•    Circuit boards: The circuit board controls all functions of the furnace. Since there are no chimneys with their natural drafts, we induce the drafts.

•    The circulation blower: It circulates the air over the heat exchanger through the duct system. They come with more efficient motors.

The most expensive, however, is the heat exchanger. The heat exchanger expands and contrasts anytime the furnace fires up. It is made out of metal; over the years, it fatigues, and that's why it's given a twenty-year lifespan.

Conclusion

The heat exchanger is a rarely replaced part of a furnace because it is very labor extensive and could fail in a short period, which a warranty can cover, but if it fails after twenty years, it's time to buy a new furnace.
