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 produced. However, there is no reason to worry. It is a natural consequence of the fuel-burning process. As long as your furnace is running properly, it is safely deposited outside your home. Carbon monoxide is kept 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.

Taking in too much carbon monoxide blocks the body from using oxygen and can damage the central nervous system and heart. While carbon monoxide poisoning can injure anyone exposed to the gas, it is especially 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 nearly impossible to notice carbon monoxide is gathering 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 pros, you should have it checked. The experts at Keystone Heating & Air Conditioning Co., Inc can make sure your blower motor is installed properly and that everything looks correct in your ductwork design. Carbon monoxide can build up if there are problems in those areas.
3. Schedule annual maintenance. Routine maintenance is the best way to prevent carbon monoxide leaks from your gas furnace. During a yearly tune-up, our experts 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 blockage of airflow caused by a spoiled filter can cause carbon monoxide to bleed out from your system. Set a reminder on your phone or mark your calendar to frequently 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.
