Your Furnace Could Be Leaking Carbon Monoxide, Here’s How to Tell


Your furnace provides warm comfort throughout the fall and winter seasons. It keeps your home cozy, but it also has a few hazards that you need to be aware of. If you stay on top of your maintenance, repairs, and know how to look for carbon monoxide leaks, you’ll be able to keep your home safe.

We want to emphasize that if you suspect a carbon monoxide leak at all, you should not address it on your own. That’s what our furnace service in Bossier City LA is for. Our expert technicians will be able to enter your home safely, turn off your furnace, and repair the source of the leak to keep your family safe.

If you don’t know how to identify a leak, here’s what you need to know.

Gas Stove Flame Colors

If you own a gas stove, you know that when you turn the knob and hear the fire click to life, it’s supposed to burn blue. If the flames come out orange or yellow, that means there’s carbon monoxide present in the air.

Sudden Headaches, Dizziness, or Nausea

Carbon monoxide exposure brings on some seriously disorienting symptoms. If you’re experiencing sudden onset headaches, random out-of-nowhere dizziness, or you’re just feeling nauseous for no discernible reason, it could be due to a carbon monoxide leak in your home.

Soot-Like Stains on Your Furnace

Your furnace should not have stains on it. If it has black soot-like stains, that’s a classic sign of a carbon monoxide leak. Keep in mind, the burners of your furnace will produce some soot-like residue as well. It’s when there’s soot-like stains all over your furnace or located in multiple areas that are not adjacent to the burners that you need to be concerned.

Cracked Heat Exchanger

This is likely where the leak is coming from in the first place. Your heat exchanger takes heat from one place and brings it to another. When you burn gas or propane, combustion byproducts escape through the heat exchanger to be vented outdoors.

Your heat exchanger is supposed to work as a container for those gasses as they travel through the flue and outside of your home. Consider it the gate for safe ventilation. If your heat exchanger cracks, a slow leak of carbon monoxide begins to poison the air in your home.

Cracked heat exchangers aren’t always visible. It’s not like seeing a large split in the side of a cast iron wood stove; they can be extremely small. If small cracks inside of the exchanger are present, carbon monoxide will leak through them. If you can already see a large split on the exterior of your heat exchanger, it’s enough of a reason to evacuate your home and call for emergency repair.

Carbon monoxide is a silent killer. It’s odorless and invisible, so you often don’t know there’s a problem until it becomes serious or life-threatening.
