The best method of detection is to use a carbon monoxide detector in your home. A carbon monoxide detector is a device very similar to a smoke alarm. It monitors the air for carbon monoxide and gives 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 very effective when used in combination with preventive maintenance. Call 317-527-0271 for more information about purchasing a carbon monoxide detector.
