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 by-product of the fuel-burning process. As long as your furnace is working properly, it is harmlessly deposited outside your home. Carbon monoxide is stored 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.

Breathing in too much carbon monoxide prevents 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 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 nearly impossible to perceive carbon monoxide is accumulating 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 JTech Mechanical 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 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 maintenance appointment, the professionals will clean your system and check it for malfunctions or problems. It’s also a good idea to have any other gas-, coal- or oil-burning appliances professionally checked as well.
4. Keep your air filter clean. A stoppage of airflow caused by a dirty 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 recommendation.
5. Always count on professionals to repair your gas furnace and other fuel-burning appliances.
