Carbon Monoxide (C02) is a potentially dangerous gas that accounts for more deaths annually in the United States than any other poisonous gas. Due to the fact that it is odorless and invisible to the naked eye, it can be very difficult to detect. It is recommended that your house be equipped with a C02 detector in the situation that you have a C02 leak in your home. Having your furnace, boiler, or other heating equipment installed and regularly maintained by a licensed and certified technician is the best way to safeguard your home and family.
