The best method of detection is to use a carbon monoxide detector in a central location. A carbon monoxide detector is like a smoke alarm. It monitors the air for carbon monoxide and gives an alarm if a specific level is detected. Ideally, you should have 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 512-592-3072 for more information about purchasing a carbon monoxide detector.
