Where should I place carbon monoxide detectors

Carbon monoxide detectors should be installed on every level of your home, including the basement, and outside each sleeping area. The most critical locations are within 15 feet of fuel-burning appliances like your furnace, water heater, and gas fireplace.

Install detectors at least 5 feet high on walls or on the ceiling, as carbon monoxide is slightly lighter than air and will mix throughout the room. Avoid placing them directly above fuel-burning appliances, in bathrooms, or near windows and doors where drafts could affect readings. In bedrooms, mount them on the wall opposite the bed so you'll hear the alarm clearly.

In Ottawa homes, pay special attention to basement placement since that's where most furnaces and water heaters are located. Install a detector within 10-15 feet of your furnace but not directly adjacent to it. If you have an attached garage, place a detector on the wall connecting the garage to your home, as car exhaust can seep through.

Replace detector batteries twice yearly - many Ottawa residents do this when we change clocks for daylight saving time. Test detectors monthly by pressing the test button. Carbon monoxide detectors should be replaced every 5-7 years, as their sensors lose sensitivity over time.

If your CO detector ever sounds, leave your home immediately and call 911. Don't try to locate the source yourself. Once emergency responders clear your home, have a licensed HVAC technician inspect all fuel-burning appliances. Annual furnace maintenance helps prevent carbon monoxide issues by ensuring proper combustion and venting.

For peace of mind with your heating system's safety, consider scheduling an annual HVAC inspection to check for proper ventilation and carbon monoxide risks.
