Your smoke detector needs to be replaced every 10 years. Old detectors have an increased 3% failure per year. After 10 years that is a 30% chance of failure. CO2 detectors need to be replaced every 5 years. We see it all the time here in Philadelphia. Old homes with old smoke alarms. Even worse, most electricians and home inspectors don't even know to warn home owners!
Find electrical answers and ideas posted by Philadelphia electricians. Hundreds of questions have been answered switches, outlets, circuit breakers, 3-way switches, GFCI outlets and more. We are based in Philly PA but we can help you no matter where your electric problem is. Our first responsibility is to help our clients and community.
