How often should carbon monoxide detectors be tested in homes with gas furnaces?

Testing carbon monoxide detectors monthly is recommended to ensure they are functioning properly and can effectively alert residents to the presence of carbon monoxide, a colorless and odorless gas that can be produced by malfunctioning gas furnaces. Monthly testing allows homeowners to verify battery life and the operational status of the detectors, ensuring they will perform as expected in case of an emergency.

This frequency is aligned with manufacturer recommendations and safety guidelines from various health organizations, emphasizing the importance of regular checks to maintain safety standards in homes utilizing gas appliances. Establishing this practice contributes to a proactive approach to home safety, particularly in households with gas heating systems where the risk of carbon monoxide exposure exists.
