Tips For Recognizing The Signs Of A Cracked Heat Exchanger


During the freezing winter months, most households run their heater often, to keep their home at a comfortable temperature. In most cases, this is not a problem at all, but heating systems can experience issues that can be very problematic and need to be repaired right away. One of the most serious problems a heating system can have is a cracked heat exchanger. A heat exchanger is a sealed component of the heating system where combustion occurs and warm air is created. If the heat exchanger in a heating system cracks, dangerous fumes, including carbon monoxide, can seep into the air. Some common signs that your heating system has a cracked heat exchanger and needs immediate repair include:

Soot Build Up

If you have a furnace that heats your home, it is always a good idea to inspect it, from time to time, to make sure that it is in good repair. If you open your furnace and notice that there is a build up of soot, there is reason to be concerned. One of the most common reasons soot builds up inside a furnace is that the heat exchanger has cracked and is allowing the soot to seep out. Never ignore a build up of soot and assume that everything will be fine-- it is essential to have your heating system inspected by an experienced HVAC professional, to determine if your heat exchanger has cracked.

Odd Smells

When your furnace is running, you should not experience any weird smells. While it is not uncommon for some homeowners to detect a slight burning odor the first time the heat is turned on for the season (due to dust particles burning off), strange smells after that are usually a warning sign. In the event that the heat exchanger has cracked, you may notice a variety of strange smells that you can't identify. It is not safe to breathe in the fumes that can flow out of a cracked heat exchanger, so your best bet is to contact an HVAC repair company right away.

Physical Symptoms

Carbon monoxide is not known for having a strong smell, but extended exposure to carbon monoxide can be deadly. If one or more family members begins to feel nauseous, light headed, or develops a headache while the heating system is running, it could be an emergency situation. In this type of situation, turn off your heating system, exit your home immediately, and call an heating repair company.
