The best method of detection is to use a carbon monoxide detector in a central location. A carbon monoxide detector is a device very similar to a smoke alarm. It monitors the air for carbon monoxide and emits an alarm if a specific level is detected. Ideally, you should have at least one detector adjacent to every living area, centrally located, or on each floor in your home. Carbon monoxide detectors are best when used in combination with a maintenance plan. Call 866-397-3787 for a complimentary consultation about purchasing a carbon monoxide detector.
