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

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

Inhaling too much carbon monoxide prevents the body from using oxygen and can hurt the central nervous system and heart. While carbon monoxide poisoning can hurt anyone exposed to the gas, it is more risky for people with existing lung or heart problems, 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 almost impossible to notice carbon monoxide is building up in your home. You may be unaware until someone starts showing symptoms of poisoning. Introduce 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 specialists, you should have it inspected. The experts at Clean Air HVAC can make sure your blower motor is installed correctly and that there are no flaws in your ductwork design. Carbon monoxide can accrue if there are problems in those spaces.
3. Schedule annual maintenance. Regular maintenance is the best step you can take 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 decent 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 bleed out from your system. Set a reminder on your phone or mark your calendar to regularly check your air filter and clean or change it per the manufacturer’s instruction.
5. Always count on professionals to service your gas furnace and other fuel-burning appliances.
