The best method of detection is to use a carbon monoxide detector in your home. A carbon monoxide detector looks a bit like a smoke alarm. It monitors the air for carbon monoxide and emits an alarm if a specific level is detected. Ideally, you should have a detector adjacent to every living area, centrally located, or on each floor in your home. Carbon monoxide detectors are most effective when used in combination with preventive maintenance. Call 925-384-1303 for a complimentary consultation about purchasing a carbon monoxide detector.
