A furnace is often a background player at home, keeping you warm across the cold winter months. It frequently isn't noticed until something goes wrong.
One root cause might be that your furnace has a cracked heat exchanger. It can be a safety risk, so it’s critical to know the signs of a cracked heat exchanger and what you can do if you are worried that is the problem.
What Is a Heat Exchanger in a Furnace?
A heat exchanger helps move heat from the combustion chamber inside your furnace to the air that flows throughout the ventilation. It usually accomplishes this through coils or tubes that heat up the air while acting as a barrier to keep gas formed in the combustion chamber, called flue gasses, from leaking out into your home.
