I’d like to add some extra smoke detectors to my home, but I want to make sure they’re reliable. Do I need to have them hardwired? – Amy from Ohio
Smoke alarms are one of the best safety features you can buy for your home and can be purchased for as little as $7. While smoke detectors are hardwired into houses in new construction, battery powered unit are best for existing homes. They are easy to install, but you need to remember to change the batteries about twice a year. Install at least one smoke alarm per level of your home near the bedrooms, and another in the garage.
