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 cause for 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 kept inside your furnace’s heat exchanger until it is safely forced through the flue vent to the outside. Carbon monoxide poisoning is a result of a malfunctioning gas furnace.

Breathing 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 affect 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 know carbon monoxide is accumulating 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 professionals, you should have it checked. The experts at Mayeuxs AC & Heating can make sure your blower motor is installed correctly and that they don’t see any flaws in your ductwork design. Carbon monoxide can build up 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 maintenance appointment, our professionals 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 serviced as well.
4. Keep your air filter clean. A backup of airflow caused by a dusty filter can cause carbon monoxide to escape 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 repair your gas furnace and other fuel-burning appliances.
