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 created. However, there is no need to worry. It is a natural by-product of the fuel-burning process. As long as your furnace is working properly, it is carefully 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 outdoors. Carbon monoxide poisoning is a result of a malfunctioning gas furnace.

Taking in too much carbon monoxide blocks the body from using oxygen and can harm 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 diseases, 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 perceive carbon monoxide is building up in your home. You may not know 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 specialists, you should have it inspected. The experts at Air Quality Solutions can make sure your blower motor is installed properly and that everything looks correct in your ductwork design. Carbon monoxide can accrue if there are problems in those territories.
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, the technicians 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 serviced as well.
4. Keep your air filter clean. A blockage of airflow caused by a dusty 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 count on professionals to repair your gas furnace and other fuel-burning appliances.
