The answer to 'carbon monoxide detector replacement schedule' is that carbon monoxide (CO) detectors should be replaced every 5-7 years, or as recommended by the manufacturer. CO detectors have a limited lifespan, and their sensors can degrade over time, reducing their ability to accurately detect dangerous levels of carbon monoxide. Replacing your CO detectors on a regular schedule ensures they will continue to protect your family from this odorless, colorless, and potentially deadly gas.
It's important to follow the manufacturer's instructions for your specific CO detector model, as some may have a different recommended replacement timeline. Additionally, it's a good idea to test your CO detectors monthly and replace the batteries twice a year to ensure they are functioning properly.
