Why Carbon Monoxide Safety Matters in Winter
Carbon monoxide (CO) is a colorless, tasteless gas produced by burning fuel, such as gas, oil, or wood. CO is vented safely outside when systems like furnaces or boilers operate correctly. But if something goes wrong, CO can build up inside your home.
The risk increases during winter, when windows are closed, and heating systems run constantly. Homes in Cherry Hill, Mount Laurel, and Burlington, especially older properties, may rely on aging systems or outdated ventilation, making carbon monoxide safety critical during the heating season.
Common Sources of Carbon Monoxide in the Home
There are several ways CO can enter your home, often through common heating and household appliances:
- Carbon monoxide from furnace systems can occur if the heat exchanger is cracked, flue pipes are blocked, or combustion is incomplete.
- Boilers and water heaters that burn natural gas or oil can also leak CO if not properly vented or maintained.
- Malfunctioning fireplaces and gas stoves may release CO indoors, especially if chimneys or vents are obstructed.
- Poorly ventilated attached garages can trap car exhaust and introduce CO to living spaces through shared walls or doorways.
If your home uses oil-burning equipment, you may want to consider an oil-to-gas conversion for improved safety and efficiency.
Symptoms of Carbon Monoxide Poisoning
Symptoms of carbon monoxide poisoning often mimic the flu, which can make them easy to overlook. These include:
- Headaches
- Dizziness or confusion
- Nausea or vomiting
- Fatigue or weakness
- Shortness of breath
In more serious cases, CO exposure can lead to unconsciousness or even death. If multiple people in your home experience these symptoms at once, especially when a fuel-burning appliance is running, evacuate immediately and seek medical help.
How To Prevent Carbon Monoxide Poisoning in Your Home
The most effective way to prevent CO buildup is through regular maintenance of your system and smart safety practices. Here’s how:
- Schedule annual heating maintenance with a qualified technician before each winter to ensure your furnace, boiler, and other systems are operating safely.
- Keep chimneys, vents, and flue pipes clear of debris, animal nests, and snow.
- Never use gas ovens or grills to heat your home, and don’t run vehicles or generators inside garages—even with the door open.
- Replace aging or inefficient systems. If your furnace is nearing the end of its lifespan, consider a furnace replacement. Similarly, schedule boiler services for any hydronic heating equipment.
Carbon Monoxide Detector Installation and Placement Tips
No matter how careful you are, the only way to be sure your home is safe is to install CO detectors. These detectors are equipped with a carbon monoxide alarm to let you know that the gas is present.
For reliable carbon monoxide detector installation:
- Place detectors on every level of your home, especially near bedrooms and sleeping areas.
- Install a unit near your furnace, boiler, or other major fuel-burning appliance.
- Avoid placing detectors next to windows, vents, or overly humid areas like bathrooms, as these can interfere with readings.
- Test detectors monthly and replace batteries at least twice a year.
- Replace entire units every 5–7 years, or according to manufacturer recommendations.
Proper CO detector placement gives your family the warning they need to act quickly in the event of a leak.
Final Heating Safety Tips for Winter
Before the cold settles in, take these extra steps to keep your home safe and warm:
- Don’t skip your fall maintenance appointment. Heating inspections catch issues before they become dangerous.
- Keep air vents and exhaust outlets unblocked by furniture, snow, or debris.
- Watch for warning signs like a yellow burner flame (instead of blue), soot buildup around burners, or an unusual smell from your heating equipment.

Frequently Asked Questions About Carbon Monoxide Safety
What are the symptoms of carbon monoxide poisoning?
Common symptoms of carbon monoxide poisoning include headache, dizziness, fatigue, nausea, and confusion. If these occur when your heating system is running—especially in multiple people—seek fresh air and call 911.
Where should I place carbon monoxide detectors in my home?
Place CO detectors on each level of your home, near bedrooms, and close to fuel-burning appliances. Avoid drafty or humid locations to ensure accurate readings.
Can my furnace cause carbon monoxide leaks?
Yes, furnaces can leak CO if components are cracked or ventilation is blocked. That’s why regular heating maintenance is critical for safety.
How often should I replace my CO detectors?
Most carbon monoxide detectors last 5–7 years. Check your model’s guidelines, test them monthly, and change the batteries at least twice a year.
How can I prevent carbon monoxide poisoning during heating season?
To prevent carbon monoxide poisoning during heating season, schedule professional HVAC inspections, install detectors, ensure appropriate ventilation, and avoid misusing fuel-burning devices. These steps are essential to prevent carbon monoxide poisoning in colder months.
