The device on your ceiling that is supposed to save your life might not work anymore.
Smoke and carbon monoxide detectors do not last forever. The sensors inside wear out, usually in seven to ten years, and an expired detector can look completely normal while doing nothing at all. Carbon monoxide is the bigger danger, because you cannot see it or smell it.
Most people test the battery and assume the unit is fine. The unit itself has a shelf life.
Three things to check today. Save this.
1. The manufacture date printed on the back of each unit
2. Whether you have a carbon monoxide detector near sleeping areas, not just smoke
3. Whether any of them are more than ten years old
If you are not sure how many you need or where they go, Hearth and Hammer can assess your home and install them correctly.
