Table of Contents
With the frost of winter setting in, families across the region are cranking up their thermostats and turning on their furnaces. Staying warm is important, but so is making sure your home is safe from one of the most silent and deadly threats of heating season, carbon monoxide. Understanding the relationship between carbon monoxide and your furnace is critical to protecting your family, particularly seniors and families who may be more susceptible to its effects.
Here at BCRC Heating and Cooling, our HVAC professionals will take you through everything you need to know about carbon monoxide and your furnace. We’ll talk about the risks, prevention tips, warning signs, and best practices to keep your home warm and safe all winter long. Check out our expert furnace installation Vancouver from here.
What is Carbon Monoxide?
Carbon monoxide (CO) is a colourless, odourless and tasteless gas produced whenever fuel is burnt. This includes natural gas, propane, oil, wood and coal. Carbon monoxide is commonly known as the “silent killer” as it is almost impossible for humans to sense.
The danger from carbon monoxide from your furnace is improper combustion or ventilation. If your furnace is running inefficiently or if the vents are blocked, it can allow CO to leak into your home, often without warning .
How Carbon Monoxide Is Produced by Furnaces
Modern furnaces have several safety mechanisms in place to prevent leaks of carbon monoxide. However, problems may be caused by:
Leaky heat exchangers
Blocked or leaking flue pipes
Poor ventilation
defective or poorly maintained burners
Old equipment
Older or poorly-maintained units are much more at risk for CO exposure. That’s why it’s so important to monitor the relationship between your furnace and carbon monoxide. Poor installation or neglect of maintenance can turn a safe heating system into a dangerous hazard in no time.
Other mistakes homeowners make are placing storage items too close to the furnace restricting airflow, or ignoring strange sounds and smells coming from the unit. Such omissions can lead to long-term damage and unsafe conditions.
Symptoms of Carbon Monoxide Poisoning
Since you can’t see carbon monoxide without special equipment, you need to be aware of the physical symptoms that it causes. Signs of early exposure:
Headaches
Vertigo
Nausea
Tiredness
Difficulty breathing
At higher concentrations or over longer periods, carbon monoxide may cause confusion, unconsciousness, or death. Those most at risk are seniors and people with respiratory or cardiovascular disease.
If several people in a house start to feel flu-like symptoms at the same time, especially without a fever, it may be due to carbon monoxide poisoning. And don’t ignore these symptoms, please. Open the windows, leave the house and call emergency services immediately.
Why Older People Are More Susceptible
Several reasons why seniors are more vulnerable to the effects of carbon monoxide include:
Warning alarms may not be heard or smelled.
People with pre-existing conditions, such as heart disease, respiratory problems or cognitive decline, may find their symptoms worsen.
Limited mobility may be a barrier to quick evacuation in an emergency.
These factors only make it more important to be proactive about safety measures in homes with elderly residents. Learn about carbon monoxide and your furnace to avoid tragedies and gain peace of mind.
Educate caregivers and family members on CO safety and ensure that the homes of seniors are regularly inspected. Prevention is better than cure, so don’t wait until symptoms appear.
Furnace Warning Signs
Knowing the unusual signs from your furnace can help prevent a CO emergency:
Soot or yellow/brown stains around the furnace or vents
Yellow or flickering pilot light (it should be blue)
Too much moisture on windows and walls.
system often shuts down
Strange smells (CO is odourless, but combustion problems can lead to noticeable odours)
In addition, a sudden spike in your energy bills may be a sign that your furnace is not functioning properly. If it is overworking because it is a ventilation problem, that can indirectly increase CO risk.
If you notice any of these signs, shut down the system and contact BCRC Heating and Cooling immediately. If you get professional help in time, the risks can be reduced before they become serious.
Stopping Carbon Monoxide Leaks
The best way to protect your home from carbon monoxide is to prevent it. Here’s how to stay safe:
Annual Furnace Tune-Up
Have your furnace inspected and professionally tuned up every year. At BCRC Heating and Cooling, we do complete maintenance including crack detection, heat exchanger testing and making sure there is adequate ventilation.
Our specialists use advanced diagnostic tools to detect the slightest deviations. A thorough inspection also makes sure that the other components, such as the thermostat, ignition system and filters are working properly.
Install Carbon Monoxide Alarms
Install CO detectors on every floor of your home, especially near bedrooms and your furnace. Test them monthly and change the batteries twice a year.
Choose good quality detectors with digital display. Some models even alert your phone. BCRC Heating and Cooling can help you determine the best detector for your home and have it installed properly.
Replace Old Furnaces
If your furnace is older than 15 years, consider a replacement. Older units are prone to leaks and are not as efficient.
Not only does upgrading to a high efficiency furnace reduce your risk of carbon monoxide exposure but it can reduce energy bills as well. We have a selection of ENERGY STAR® rated furnaces with the newest safety features.
