That “Test” button on your CO detector is lying to you!
Hearing the beep only means the battery and speaker work—it DOES NOT mean the actual gas sensor is functioning. CO sensors degrade over time and expire completely every 5 to 7 years.
Your Tuesday Task: Take your detectors off the wall and check the date stamped on the back. If they are expired, they won’t protect your family from an odorless leak this winter!
