As your Phoenix Electrical Contractor we want you and your family to be safe in your home. We know smoke alarms are not something that most people worry about but they should. Smoke alarms should be replaced every 10 years. To check the age of your smoke alarms you should look at the manufacture date listed on the back. If it is over 10 years you need to replace it. As a Phoenix Electrical Contractor we have seen homes without working smoke detectors, homes with dead batteries in their smoke detectors and ancient obsolete smoke detectors. If you hear a chirp sound that means the back up battery for your smoke detector is going bad. Don’t put off something so important for you and your families safety any longer, any Phoenix Electrical Contractor can help you check and replace your smoke detectors with new and improved detectors.
