Answer: Can My HVAC System Cause Carbon Monoxide Poisoning?

Yes — any gas-fired HVAC equipment that burns natural gas, propane, or oil can produce carbon monoxide if not operating correctly. A cracked heat exchanger in a furnace, blocked flue in a boiler, or malfunctioning burner can allow CO to enter your living space. CO is colourless and odourless, making it especially dangerous. Symptoms of CO exposure include headache, dizziness, nausea, and confusion. Every home with gas appliances should have working CO detectors on each floor. If your CO detector alarms, evacuate immediately and call 911. We recommend annual inspection of all gas-fired equipment to prevent CO risks.
