Understanding Carbon Monoxide Risks in Your Home

Winter is here, and that means your furnace is working overtime to keep your home warm and cozy. But while you’re enjoying the heat, there’s a hidden danger that many homeowners overlook: carbon monoxide risks. This colorless, odorless gas is a byproduct of burning fuel, and if it leaks into your home, it can be deadly.
The good news? With a little knowledge and some proactive maintenance, you can keep your family safe from carbon monoxide exposure. Let’s break it down.

How Do Carbon Monoxide Leaks Happen?

Carbon Monoxide Risks - HVAC Solutions

Your furnace is designed to vent harmful gases safely outside your home, but when something goes wrong — like a cracked heat exchanger, a blocked vent, or a malfunctioning burner — carbon monoxide risks increase significantly. Instead of being safely expelled, carbon monoxide can seep into your living spaces, putting everyone at risk.
Common causes of carbon monoxide leaks include:

• Cracked or rusted heat exchangers
• Blocked or disconnected vent pipes
• Incomplete combustion due to dirty burners
• Poor ventilation in confined spaces
• Backdrafting from other appliances

Because carbon monoxide is invisible and has no smell, it’s impossible to detect without a proper alarm. That’s why taking precautions is crucial.

Warning Signs of Carbon Monoxide Poisoning

One of the scariest things about carbon monoxide risks is that exposure can mimic common illnesses. If your furnace is leaking carbon monoxide, you or your family members might experience:

• Headaches
  
• Dizziness
  
• Nausea
  
• Confusion
  
• Shortness of breath
  
• Flu-like symptoms that seem to improve when you leave the house
  

In severe cases, prolonged exposure can lead to unconsciousness or even death. If you suspect a carbon monoxide leak, take action immediately.

How to Protect Your Home from Carbon Monoxide Risks

1. Schedule Regular Furnace MaintenanceRoutine maintenance is the easiest way to prevent carbon monoxide risks. A professional HVAC technician can inspect your furnace, clean the burners, check for cracks, and ensure your system is venting properly.

2. Install Carbon Monoxide DetectorsEvery home with a gas furnace should have carbon monoxide detectors installed on every level, especially near bedrooms. Test them regularly and replace the batteries twice a year.

3. Keep Vents & Flues ClearBlocked vents can cause carbon monoxide to back up into your home. Make sure snow, leaves, or debris aren’t obstructing your furnace’s exhaust pipe.

4. Never Use Outdoor Appliances IndoorsIt may seem obvious, but people sometimes use outdoor heaters, generators, or grills inside their homes or garages for extra warmth. This is a huge carbon monoxide hazard and should always be avoided.
​
5. Know When to Call a ProfessionalIf your carbon monoxide detector goes off or you notice signs of a leak, don’t take any chances. Turn off your furnace, open windows to ventilate, and get out of the house. Then, call an HVAC professional immediately.

1. Turn off your furnace and any other fuel-burning appliances.
   
2. Ventilate your home by opening windows and doors.
   
3. Evacuate immediately — don’t try to "wait it out."
