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

Breathing in too much carbon monoxide blocks the body from using oxygen and can hurt the central nervous system and heart. While carbon monoxide poisoning can injure anyone exposed to the gas, it is more risky for people with existing lung or heart diseases, 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 almost impossible to perceive carbon monoxide is accumulating in your home. You may not know until someone starts showing symptoms of poisoning. Introduce 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 checked. The experts at Controlled Comfort HVAC Inc can make sure your blower motor is installed properly and that they don’t see any flaws in your ductwork design. Carbon monoxide can collect if there are problems in those areas.
3. Schedule annual maintenance. Routine maintenance is the best way to prevent carbon monoxide leaks from your gas furnace. During a yearly checkup, our experts will clean your system and check it for malfunctions or problems. It’s also a great 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 spoiled 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 rely on professionals to service your gas furnace and other fuel-burning appliances.
