Does Your Furnace Have a Cracked Heat Exchanger?


There are a lot of intricate and important parts that make your furnace, well, furnace. We don’t want to downplay any part of this system; they all have a vital or near-vital role in heating up your home. With that said, there is one part of your furnace that does deserve a little extra attention: your heat exchanger.

When there is a problem with your heat exchanger, it can ruin your home comfort and can create other issues for your health and safety. That is why a cracked heat exchanger is well worth a call to a professional for furnace repair in Ashland, KY.

What Your Heat Exchanger Does

The heat exchanger is a part of your natural gas furnace that captures combustion gases, created by burning natural gas. As the heat exchanger fills, the heat in the gas within is allowed to transfer through the metallic body of your heat exchanger. That heat then warms the air around the heat exchanger which is blown into your home. Without a heat exchanger, your furnace wouldn’t be able to provide much heat.

Why a Cracked Heat Exchanger Is a Big Problem

Time and regular use can and will take their toll on your furnace, your heat exchanger included. Regular stress can create small cracks in the body of the heat exchanger. While these cracks can be nearly microscopic, they are still a big risk.


Because your heat exchanger is holding a variety of combustion gases such as carbon monoxide that you don’t want in the air in your home. And a crack in your heat exchanger runs the risk of letting those gases leak out of the exchanger and into the air being blown into your home.
