Carbon Monoxide and Your Furnace: How to Stay Safe This Winter
Table of Contents
As the chill of winter settles in, families across the region are turning up their thermostats and firing up their furnaces. While staying warm is essential, it’s equally important to ensure that your home is safe from one of the most silent and deadly threats during the heating season: carbon monoxide. Understanding the relationship between carbon monoxide and your furnace is critical to safeguarding your family, especially for seniors and households who may be more vulnerable to its effects.
In this article, the HVAC professionals at BCRC Heating and Cooling will guide you through everything you need to know about carbon monoxide and your furnace. We’ll explore the risks, prevention tips, warning signs, and the best practices to keep your home warm and safe all winter long.
What is Carbon Monoxide?
Carbon monoxide (CO) is a colorless, odorless, and tasteless gas that is produced whenever fuel is burned. This includes natural gas, propane, oil, wood, and coal. Because it’s virtually undetectable by human senses, CO is often referred to as the “silent killer.”
When it comes to carbon monoxide and your furnace, the danger lies in improper combustion or ventilation. If your furnace isn’t working efficiently or has blocked vents, it can cause CO to leak into your home — often without any warning.
How Furnaces Produce Carbon Monoxide
Modern furnaces are designed with multiple safety mechanisms to prevent the leakage of carbon monoxide. However, problems can still occur due to:
Cracked heat exchangers
Blocked or leaking flue pipes
Inadequate ventilation
Faulty or poorly maintained burners
Aging equipment
In older units or those that are not regularly maintained, the risk of CO exposure increases dramatically. This is why the relationship between carbon monoxide and your furnace is so crucial to monitor. Poor installation or skipped maintenance can quickly turn a safe heating system into a dangerous hazard.
Some common mistakes homeowners make include placing storage items too close to the furnace, which can restrict airflow, or ignoring strange sounds and smells coming from the unit. These oversights can lead to long-term damage and unsafe conditions.
Symptoms of Carbon Monoxide Poisoning
Because carbon monoxide is undetectable without special equipment, you must be aware of the physical symptoms it causes. Early signs of exposure include:
Headaches
Dizziness
Nausea
Fatigue
Shortness of breath
At higher levels or with prolonged exposure, carbon monoxide can lead to confusion, unconsciousness, and even death. Seniors and those with respiratory or cardiovascular conditions are particularly at risk.
If multiple members of a household begin experiencing flu-like symptoms at the same time — especially without a fever — carbon monoxide poisoning could be the cause. Don’t ignore these symptoms. Open windows, leave the house, and call emergency services immediately.
Why Seniors Are More Vulnerable
Seniors are more susceptible to the effects of carbon monoxide for several reasons:
Reduced sense of smell and hearing may prevent awareness of warning alarms.
Pre-existing health conditions like heart disease, respiratory issues, or cognitive decline can exacerbate symptoms.
Limited mobility might hinder quick evacuation in emergencies.
These factors make proactive safety measures especially important in homes with elderly residents. Understanding carbon monoxide and your furnace can prevent tragic outcomes and provide peace of mind.
Caregivers and family members should also be educated about CO safety and ensure that the homes of seniors are inspected regularly. Don’t rely solely on symptoms — prevention is always more effective than reaction.
Warning Signs from Your Furnace
Being aware of unusual signs from your furnace can help prevent a CO emergency:
Soot or yellow/brown stains around the furnace or vents
A yellow or flickering pilot light (it should be blue)
Excess moisture on windows and walls
Frequent system shutdowns
Odd smells (though CO is odorless, combustion issues can produce noticeable odors)
Additionally, if your energy bills suddenly increase, this could be a sign that your furnace is not operating efficiently. It may be overworking due to a ventilation problem, which can indirectly increase CO risk.
If you notice any of these signs, turn off the system and call BCRC Heating and Cooling immediately. Prompt professional attention can mitigate risks before they escalate.
Preventing Carbon Monoxide Leaks
Prevention is the best way to protect your home from carbon monoxide. Here’s how to stay safe:
Annual Furnace Maintenance
Schedule a professional furnace inspection and tune-up every year. At BCRC Heating and Cooling, we offer comprehensive maintenance services that include checking for cracks, testing the heat exchanger, and ensuring proper ventilation.
Our experts use advanced diagnostic tools to detect even the smallest irregularities. A thorough inspection also ensures that other components — like the thermostat, ignition system, and filters — are working properly.
Install Carbon Monoxide Detectors
Place CO detectors on every floor of your home, especially near bedrooms and your furnace. Test them monthly and replace batteries twice a year.
Be sure to choose high-quality detectors with digital displays. Some models even send alerts to your phone. BCRC Heating and Cooling can help you choose the best detector for your home and ensure proper installation.
Replace Aging Furnaces
If your furnace is over 15 years old, it may be time to consider a replacement. Older units are more prone to leaks and inefficiencies.
Upgrading to a high-efficiency furnace not only lowers your risk of carbon monoxide exposure but can also save money on energy bills. We offer a range of ENERGY STAR®-rated furnaces with modern safety features.

Ensure Proper Ventilation
Never block furnace vents or exhaust flues. Ensure that chimneys and flues are clear of debris, nests, or snow. Poor airflow can lead to CO buildup and decreased heating performance.
Have your air ducts inspected regularly as well. Blockages in the system can trap harmful gases inside your home.
Use Appliances Safely
Never use ovens or stovetops to heat your home. Avoid running gas-powered generators inside garages or enclosed spaces. Always follow the manufacturer’s safety guidelines for any fuel-burning appliances.
Make sure fireplaces and wood-burning stoves are inspected annually. Use proper fuel and make sure chimneys are cleaned and clear.
The Importance of Professional Help
While DIY solutions can be tempting, carbon monoxide and your furnace require the expertise of trained HVAC technicians. Professional inspections can identify issues that may not be visible to the average homeowner. At BCRC Heating and Cooling, our certified technicians have years of experience diagnosing and repairing furnace problems that could lead to CO exposure.
We also provide post-repair testing to ensure that CO levels are safe. From heat exchanger diagnostics to flue testing, our comprehensive service leaves nothing to chance.
