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

February 06, 2017
Whenever your gas furnace is running, carbon monoxide is being produced. However, there is no reason to worry. It is a natural consequence 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 forced through the flue vent to the open air around your home. Carbon monoxide poisoning is a consequence of a malfunctioning gas furnace.

Taking in too much carbon monoxide prevents the body from using oxygen and can damage the central nervous system and heart. While carbon monoxide poisoning can affect anyone exposed to the gas, it is more risky for people with existing lung or heart issues, pregnant woman, infants and children. Here are some tips to ease your mine mind and preserve 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 gathering in your home. You may be unaware until someone starts showing symptoms of poisoning. Put 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 pros, you should have it inspected. The experts at Kirkfield Heating & Air Conditioning can make sure your blower motor is installed correctly and that everything looks correct in your ductwork design. Carbon monoxide can collect 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 checkup, your technicians will clean your system and examine it for malfunctions or problems. It’s also a good idea to have any other gas-, coal- or oil-burning appliances professionally checked as well.
4. Keep your air filter clean. A stoppage of airflow caused by a dirty filter can cause carbon monoxide to leak out of 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 specifications.
5. Always count on professionals to fix your gas furnace and other fuel-burning appliances.
