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 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 pushed through the flue vent to the open air around your home. Carbon monoxide poisoning is a consequence of a malfunctioning gas furnace.

Breathing in too much carbon monoxide prevents the body from using oxygen and can hurt the central nervous system and heart. While carbon monoxide poisoning can affect 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 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 practically impossible to perceive carbon monoxide is accumulating in your home. You may not be aware 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 professionals, you should have it inspected. The experts at Bon Air Service Company 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. Regular maintenance is the best action to take to prevent carbon monoxide leaks from your gas furnace. During a yearly tune-up, your technicians will clean your system and inspect it for malfunctions or problems. It’s also a good idea to have any other gas-, coal- or oil-burning appliances professionally serviced as well.
4. Keep your air filter clean. A backup of airflow caused by a dirty 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 specifications.
5. Always depend on professionals to repair your gas furnace and other fuel-burning appliances.
