If you have a chirping smoke detector, it is most likely driving you up the wall. The good news: Now that you’re up the wall, you’re closer to the smoke detector, and it’s easier to change the battery, which is probably why the thing’s chirping in the first place! (Because the battery’s dying.)
However, there are a couple of scenarios in which the chirping is caused not by a battery that’s on the way out, but by a smoke detector that’s malfunctioning despite getting enough juice.
Changing a smoke detector battery is a pretty straightforward affair. But if the battery’s still powering the unit, you’ll need to take a few more steps to determine the cause of that blasted chirp-chirp-chirping!
