November brings the first stretch of steady cold to Youngstown, Boardman, and Salem, and furnaces across the Mahoning Valley are running longer every day. That extra runtime is a good reminder to think about carbon monoxide, a colorless and odorless gas that can build up indoors when a fuel-burning appliance is not working the way it should. Clayton Heating and Air Conditioning has helped Northeast Ohio families stay warm and safe since 1959, and carbon monoxide awareness is one of the simplest ways to protect your household all winter.
Where Carbon Monoxide Comes From
Carbon monoxide forms when fuels like natural gas, propane, or oil do not burn completely. A properly installed and maintained gas furnace sends its combustion gases safely outdoors through the flue pipe. Trouble starts when something interrupts that process, such as a cracked heat exchanger, a damaged or blocked flue, or burners that have drifted out of adjustment. Water heaters, gas ranges, fireplaces, and attached garages can also be sources, so whole-home awareness matters.
Warning Signs Worth Taking Seriously
Because you cannot see or smell it, carbon monoxide often shows up first as symptoms that feel like the flu. Headaches, dizziness, nausea, and unusual fatigue that improve when you leave the house are a red flag. Around the furnace itself, watch for these signs.
- A yellow or flickering burner flame instead of a steady blue one
- Soot or rust stains around the furnace or flue pipe
- Heavy condensation on windows whenever the heat is running
- A pilot light that keeps going out
If your alarm sounds or anyone feels symptoms, get everyone outside, call 911, and stay out until responders say it is safe. The CDC carbon monoxide resource page offers additional safety guidance.
Simple Steps to Protect Your Household
Working carbon monoxide alarms are your first line of defense. Place one on every level of your home and outside each sleeping area, test them monthly, and replace them on the schedule the manufacturer recommends. Keep the space around your furnace clear of boxes, paint cans, and clutter so the equipment gets the combustion air it needs.
The most important step is a yearly furnace safety inspection. Our technicians check the heat exchanger for cracks, test combustion, confirm the flue is drawing properly, and make sure every safety control works as designed. If your furnace is showing its age, a high-efficiency Trane furnace with sealed combustion adds built-in safeguards along with lower heating costs. And when winter storms knock out power, never run a portable generator in a garage or near open windows. A Kohler whole-home generator installed outdoors by our team keeps your heat running safely.
