A smoke alarm that beeps periodically, often every 30 to 60 seconds, usually indicates a low battery. The first step is to replace the battery. If this doesn't solve the problem, try resetting the alarm. However, beeping can also signal other issues, such as dust buildup in the sensors or the unit reaching the end of its life. Different beep patterns can mean different things; for example, multiple beeps might indicate an issue with a combination carbon monoxide detector, while a continuous, loud alarm means smoke has been detected. If a new battery doesn't stop the beeping, it's best to consult your alarm's manual, call a professional, or replace the unit.

It’s shaped like a double triangle and is installed behind the chimney so that falling water spills evenly down each side. This helps prevent water from accumulating behind your chimney, which can increase water damage and the risk of leaks. 

The International Building Code (IBC) requires cricket installation if a chimney built after 2012 measures over 30 inches in width. Chimneys constructed before that date are typically grandfathered in and aren’t required to have crickets installed.

If you hear a crackling, popping, or hissing sound when you use the switch, it indicates live electricity arcing inside, which is a significant hazard that can ignite nearby flammable materials. If you suspect your light switch is faulty, turn off the power to that circuit at the breaker and contact a qualified electrician to remedy the issue.
