What is a heat exchanger, and why is it important?

The heat exchanger is a vital component of a furnace. It prevents dangerous gases from mixing with the heated air, ensuring that exhaust gases are vented safely outside while clean, heated air is distributed throughout your home. A cracked heat exchanger is a serious safety hazard, as it can allow carbon monoxide to leak into your home. Consult with an HVAC professional if you suspect a problem with your heat exchanger.
