Carbon monoxide is clear and odorless, so the only way to detect it is to have carbon monoxide detectors in several locations around your home in Pasadena, MD. Carbon monoxide is very hazardous to your health, and monitoring it with detectors is the only way to know if your home has a leak. Never use grills or ovens for sources of heat. Be sure you allow your vehicle, lawnmower, or snowmobile to warm up outside of your home and not in your garage with the door closed.
