How often do I need to replace my smoke detectors?
Newer smoke detectors have approximately an 8 to 10 year lifespan of reliable service, according to the U.S. Fire Administration. Change them when they reach that age, even if they still seem to be functioning properly. Replace all the detectors when you move into a new home, if you are unsure of their age.
