Skylands Energy Service provides top-notch heating and cooling services throughout Central New Jersey. If the temperature rise is too low, the discharge air might feel cool when coming out of a register, areas of the house may be hard to heat or problems with condensation in the flue or on the inside of the heat exchanger may occur. If this happens, you'll want to contact an HVAC company right away. If your gas furnace is about that age, the chances are high that the heat exchanger can crack. The same goes for your pets! If there is a heat exchanger crack, it can cause carbon monoxide gas (CO) to leak out of your gas furnace. Besides carbon monoxide, a cracked heat exchanger can also cause the leakage of gases such as sulfur dioxide and nitrogen dioxide. So let's get into it!
Cracked Heat Exchanger Repair
When I inspect a furnace and I find a cracked heat exchanger (and I find a lot of them), I always say to replace it. Nowadays, checking for a cracked heat exchanger is way more scientific. The furnace was replaced when the air-conditioner had to be replaced. Most of the time, there are no warning signs of a crack until it's already become deadly. Here's an excerpt from an October 1, 2004 Contracting Business Article titled "Carbon Monoxide: Let's Stop The Madness! " There is some kind of "interaction" between the secondary and primary heat exchangers that creates turbulence that somehow negates the static pressure around the secondary heat exchanger. A heat exchanger crack in a residential furnace large enough to cause trouble usually upsets a steady flame or causes the burner flames to roll out the front of the burner openings. What To Do If You Have A Cracked Heat Exchanger? Perhaps unsurprisingly, if you have an improperly sized furnace, your heat exchanger will crack much more quickly than a correctly sized furnace. There are only two signs you might notice if your heat exchanger is cracked: You don't have heat in your home, or your carbon monoxide detector is beeping. Over time this wears out the heat exchanger. When a crack occurs, usually there are no early warning signs until it has become nearly fatal. I've been on dozens of service calls where the gas utility told the customer to replace their furnace because of a crack in the heat exchanger that had NOTHING to do with the high CO levels in the house. That's why you should watch out for the cracked heat exchanger symptoms.
Is A Cracked Heat Exchanger Dangerous
My concern is the fact that mechanics walk past other potential carbon monoxide poisoning issues to get to heat exchanger inspection. This is usually due to insufficient airflow, which is often because of the lack of maintenance. So what causes this? So don't take any chances with visual analysis. A typical furnace flame should be blue. Carbon monoxide can leak through the cracked heat exchanger. This is from an ACHR News article: Howard Leonard is president of Total Tech HVACR Training, Phoenix, AZ.
How To Check For Cracked Heat Exchanger
Either way, it requires some serious considerations. In turn, excess heat causes your heat exchanger to crack. Cracked heat exchangers are a problem usually isolated to aging furnaces—that is, any furnace over 15 years old. Dominick Guarino is chairman and CEO of National Comfort Institute, a national training, and certification organization focused on air diagnostics, CO and combustion, and IAQ. Are there cracks and rust? The heat exchanger is one of them, and we check it during every fall maintenance inspection. The combustion analyzer also helps us gauge the overall performance of your furnace. If you see evidence of soot, a black carbon buildup, on the inside of the furnace, it's a sign your furnace isn't burning cleanly.
Hvac Cracked Heat Exchanger
There might be corrosion and cracks on your furnace's external components. When there's CO present, we'll know it. But in my experience looking at furnaces, I'd guess that at least 10% of all the gas furnaces in operation today have heat exchanger cracks. I would like to know who started this myth. CO detectors are set to go off at high levels (usually around 400 ppm). There could be a number of reasons why the fuel isn't being burned properly, with one of them being that the heat exchanger has been cracked. Many people use fuel oil, natural gas, or propane to power their heating systems. Our professionally certified and trained technicians offer high-quality services, such as AC maintenance, furnace repairs, boiler installations, ductless systems, and more. There are certain signs to look for to determine if the heat exchanger has been cracked. It is an essential part of your heating system, and any issues with it will not only lead to a breakdown of your furnace but also pose serious risks to the health and safety of your home. When internal temperature increases, there is a high likelihood that the heat exchanger will crack. Combustible gas increases in temperature and collects in the heat exchanger, allowing it to increase the temperature of the air.

If you have any concerns about your heater, do not hesitate to call your local HVAC contractor to discuss solutions and preventative steps. Because they still only perform visual heat exchanger inspections. This is because, since the heat exchanger is situated in the middle of the furnace, the entire furnace must be disassembled in order to replace the heat exchanger. Six Signs Your Furnace Heat Exchanger May be Cracked. Schedule a service appointment with us today to receive a free, no-obligation, in-home estimate. Cracks in the heat exchanger can develop much faster if your furnace is poorly maintained or improperly installed. Another issue that results from an oversized furnace is condensation. Using a combustion analyzer gives a clearer picture of how the furnace is operating. That amount of air is based on the heat output of the gas burners and is a design decision made by a manufacturer's engineering team. Physical problems seen on the outside could point to internal damage as well. This happens because of insufficient airflow – a problem that often occurs due to lack of maintenance. Learn how a furnace tune up can protect your home and how you can provide maintenance for your furnace on your own here. If there are loose return-air connections or openings around the air filter, the CO that has accumulated at the front of the furnace could be pulled into the return air stream and pushed throughout the house. If you have a high- efficiency furnace (90%+) then you also have a secondary heat exchanger.
Your CO detector uses a silica gel and a sensor to detect the presence of carbon monoxide in the air. It never causes an issue, though, because it has very little. If you're lucky, your furnace will stop working, but often, your furnace will keep running even with a crack and will let carbon monoxide into your home. It is worth watching this 10 minute video.
