Smoke alarms are devices that detect smoke and emit an alarm sound to notify you of a potential fire.

They need professional installation but are more reliable in the long run.

Carbon monoxide detectors work by sensing the amount of CO in the air and emitting an alarm when the levels are dangerous. There are two types of CO detectors that are battery-operated and plug-in. For plug-in detectors, professional assistance is required for installation while battery-operated detectors are easy to install and maintain.

CO detectors should be tested at least once per month and replaced after 5 to 7 years. It is essential to put CO detectors close to sleeping areas and at every level of your house, including the basement.
