Gas Furnaces and Carbon Monoxide: The Risks and How to Protect Your Family

February 06, 2017
Whenever your gas furnace is working, carbon monoxide is being created. However, there is no need to worry. It is a natural result of the fuel-burning process. As long as your furnace is operating properly, it is safely deposited outside your home. Carbon monoxide is stored inside your furnace’s heat exchanger until it is safely moved through the flue vent to the outdoors. Carbon monoxide poisoning is a consequence of a malfunctioning gas furnace.

Inhaling too much carbon monoxide blocks the body from using oxygen and can damage the central nervous system and heart. While carbon monoxide poisoning can hurt anyone exposed to the gas, it is notably risky for people with existing lung or heart issues, pregnant woman, infants and children. Here are some tips to ease your mine mind and maintain a healthy, comfortable and safe home.

1. Invest in carbon monoxide detectors. Carbon monoxide is a colorless and odorless gas that can’t be detected by humans. Without a detector, it’s nearly impossible to notice carbon monoxide is building up in your home. You may not be aware until someone starts showing symptoms of poisoning. Install carbon monoxide detectors on every floor of your home, ideally near bedrooms, to be alerted to rising levels before anyone gets sick.
2. Be sure your gas furnace was installed properly. If your gas furnace wasn’t installed by professionals, you should have it looked at. The experts at Fleming Heating & Air Conditioning Inc can make sure your blower motor is installed properly and that they don’t see any flaws in your ductwork design. Carbon monoxide can build up if there are problems in those territories.
3. Schedule annual maintenance. Routine maintenance is the best way to prevent carbon monoxide leaks from your gas furnace. During a yearly tune-up, your professionals will clean your system and check it for malfunctions or problems. It’s also a great idea to have any other gas-, coal- or oil-burning appliances professionally monitored as well.
4. Keep your air filter clean. A stoppage of airflow caused by a dusty filter can cause carbon monoxide to escape your system. Set a reminder on your phone or mark your calendar to routinely check your air filter and clean or change it per the manufacturer’s instruction.
5. Always rely on professionals to fix your gas furnace and other fuel-burning appliances.
