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 produced. However, there is no cause for worry. It is a natural by-product of the fuel-burning process. As long as your furnace is running properly, it is harmlessly deposited outside your home. Carbon monoxide is stored inside your furnace’s heat exchanger until it is safely pushed through the flue vent to the outside. Carbon monoxide poisoning is a result of a malfunctioning gas furnace.

Breathing in too much carbon monoxide blocks the body from using oxygen and can damage 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 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 know carbon monoxide is building up in your home. You may be unaware 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 professionals, you should have it checked. The experts at Precision Mechanical can make sure your blower motor is installed correctly and that everything looks correct in your ductwork design. Carbon monoxide can accrue if there are problems in those territories.
3. Schedule annual maintenance. Routine maintenance is the best action to take 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 backup of airflow caused by a spoiled 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 rely on professionals to service your gas furnace and other fuel-burning appliances.
