Smoke Detector Cleaning


When was the last time you cleaned your smoke detectors? Just as your car, air conditioning system and dryer vent require maintenance in order to function optimally, so do your smoke detectors. A clean smoke detector is a happy smoke detector. More importantly, a clean detector is better suited to do its job and not give you a false alarm; or even worse, no alarm at all!

Smoke detectors tend to be up and out of sight, consequently we often forget about them, until they give us a subtle (or loud) reminder they are there. While our smoke detectors sit quietly waiting to warn us, they are collecting dust like all the rest of our precious valuables. And like those precious valuables, our smoke detectors need to be cleaned to work as well as they can when needed.

There are no second chances when it comes to warnings and fire detection warnings are essential in keeping your family, your home and your belongings safe.


The reason smoke alarms activate between the hours of 2-6am when there is no fire is because that is the coolest time in a house. Any dust that has settled in the alarm drops into the sensor, and the sensor mistakes dust for smoke. Clean your alarms annually to avoid false alarms!!

  • Also, as a smoke alarm's battery nears the end of its life, the amount of power it produces causes an internal resistance. A drop in room temperature increases this resistance, which may impact the battery's ability to deliver the power necessary to operate the unit and cause a detector to enter the low battery chirp mode when air temperatures drop.
