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 reason to worry. It is a natural consequence of the fuel-burning process. As long as your furnace is running 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 open air around your home. Carbon monoxide poisoning is a product 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 affect anyone exposed to the gas, it is more 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. 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 pros, you should have it inspected. The experts at Rapids Sheet Metal Works Inc can make sure your blower motor is installed correctly and that everything looks correct 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 way to prevent carbon monoxide leaks from your gas furnace. During a yearly tune-up, your professionals will clean your system and inspect 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 leak out of 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 instruction.
5. Always count on professionals to repair your gas furnace and other fuel-burning appliances.
