10. Smoke detectors will trigger if they get dusty

They work by looking for something obstructing a gap (such as smoke). If they get some dust build up in the gap, they will falsely trigger. If it's been in place a long time, there could be a buildup in the sensor gap. They're not really difficult to replace, if you have a ladder and a couple of tools.

Good luck.
