If you\u2019re like most homeowners in our area, you use a\nfurnace heating system to keep your living space warm during the winter.\nGas-powered furnaces are the most popular type of residential heating system\nacross the country, after all. <\/p>\n\n\n\n

They not only produce a large amount of heat, but they do so at less expense than electric furnaces because natural gas costs less than electricity per unit. <\/p>\n\n\n\n

However, natural gas appliances do come with a risk. That\u2019s\nnot to say they\u2019re inherently dangerous. But if you skip maintenance or don\u2019t\nkeep up on small repair needs, problems can grow and you can end up with a\ndangerous situation on your hands. One of these possible situations is a\ncracked heat exchanger. <\/p>\n\n\n\n\n\n\n\n

What Is a Heat Exchanger?<\/h2>\n\n\n\n

This component is what enables your furnace to heat up the\nair that travels through the ductwork of your heating system. When the burners\nof your furnace ignite, they generate hot combustion gas, which is collected\ninside the heat exchanger\u2014a metal chamber or series of chambers. Most of them\nhave a clam-shell shape. <\/p>\n\n\n\n

The hot combustion gas in the heat exchanger heats up the metal walls, and the blower fan of the furnace comes on and sends air around the heat exchanger, where it picks up the heat from the furnace wall and continues through the ducts. <\/p>\n\n\n\n

Once the heating process is complete, the combustion byproducts in the heat exchanger are vented out of the system through a flue, to release gas harmlessly into the air outside. <\/p>\n\n\n\n

A Cracked Heat Exchanger<\/h2>\n\n\n\n

Since the metal of the heat exchanger expands and then\ncontracts as it heats and cools, the stress can eventually cause a crack to\nform on the exchanger. Corrosion due to the reaction between the combustion gas\nand the metal\u2014usually due to improper venting or even old age\u2014can also weaken\nthe metal to the point where cracks form. <\/p>\n\n\n\n

These cracks can be small, but as the exchanger expands with\nthe heat, cracks can open enough to allow some of the combustion gasses to\nescape and enter your living space. This means these harmful gasses will be\nsent through the house. <\/p>\n\n\n\n

How Do You Know If You Have a Cracked Heat Exchanger?<\/h2>\n\n\n\n

How can you tell if your\n<\/em>heat exchanger is cracked? A major warning sign is if you hear a clicking\nsound from the furnace soon after the blower shuts off. This should always be\ninvestigated. <\/p>\n\n\n\n

Also, if you see corrosion anywhere on your furnace, this is\nalso the sign of a problem, and you should probably have the furnace replaced\nat this point if it\u2019s over 15 years old. <\/p>\n\n\n\n

If your CO (carbon monoxide) alarms go off, you should exit\nthe home and call for emergency services. You\u2019ll want to have an HVAC\nprofessional check on your furnace system once the initial danger is past. It\nwill likely benefit you to upgrade the system at this point, so please don\u2019t\nhesitate to ask us about your options! <\/p>\n\n\n\n
