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 reason to worry. It is a natural by-product of the fuel-burning process. As long as your furnace is running properly, it is carefully 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 open air around your home. Carbon monoxide poisoning is a result of a malfunctioning gas furnace.

Taking in too much carbon monoxide stops 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 sustain 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. 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 inspected. The experts at West Jefferson Plumbing and Heating, Inc. can make sure your blower motor is installed accurately 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. Routine maintenance is the best way to prevent carbon monoxide leaks from your gas furnace. During a yearly tune-up, the 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 backup 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 repair your gas furnace and other fuel-burning appliances.
