If I’m a current Guardian customer, can I add a carbon monoxide (CO) detector to my monitored service?

Absolutely! We encourage all of our customers to help protect their homes and loved ones from dangerous carbon monoxide exposure with monitored CO detectors. The great news is that professional CO monitoring is included with every service plan, so if you’re already a Guardian customer, all you need to do is to add one or more CO detectors to your system. Just give us a call at 1.800.PROTECT (1.800.776.8328) and we’ll take care of the rest!
