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 by-product of the fuel-burning process. As long as your furnace is operating properly, it is carefully deposited outside your home. Carbon monoxide is contained 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 stops the body from using oxygen and can hurt 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 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 specialists, you should have it inspected. The experts at Air Alliance Team can make sure your blower motor is installed correctly and that there are no flaws in your ductwork design. Carbon monoxide can build up if there are problems in those territories.
3. Schedule annual maintenance. Annual maintenance is the best step you can take to prevent carbon monoxide leaks from your gas furnace. During a yearly checkup, our experts will clean your system and examine 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 dusty filter can cause carbon monoxide to escape 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 recommendation.
5. Always depend on professionals to fix your gas furnace and other fuel-burning appliances.
