Carbon Monoxide Hotspots at Home
Carbon monoxide in your home is never a good thing. Because it has no odor, color, or taste, it is impossible to detect it simply by our senses. According to the Center for Disease Control (CDC), over 6,000 people were killed by unintentional carbon monoxide poisoning in their homes from 1999 to 2012. Senior citizens over the age of 85 were those experiencing the highest death rates due to carbon monoxide poisoning, most likely due to improper maintenance of fuel-burning devices in the home.

How Is Carbon Monoxide Produced?
The production of carbon monoxide occurs whenever any material burns. Homes with fuel-burning appliances are much more likely to suffer from potentially dangerous carbon monoxide issues. High levels of carbon monoxide can lead to a loss of oxygen in the body, causing flu-like symptoms, long-term respiratory problems, and can even be fatal.
How Do You Prevent Carbon Monoxide in Your Home?
Placing several carbon monoxide detectors throughout your home is the first and most crucial step toward avoiding potential problems caused by carbon monoxide buildup. Next, know where to find the potential carbon monoxide hotspots in your home. Learning about ways to remedy potential issues - before they become dangerous - is another vital aspect of overall home safety.
Below, we look at four different potential carbon monoxide hotspots in a typical home and offer a simple solution to avoid carbon monoxide buildup.
Gas and Oil Burning Furnaces
During the long winter months, your furnace probably stays running non-stop to keep your home warm and comfortable. However, Furnaces can contribute to carbon monoxide buildup in the home through both leaks and improper combustion. For natural gas-powered furnaces, a mostly yellow flame in color might signal that fuel is not burning completely, thus leading to excess carbon monoxide.
Moreover, the combustion chamber and internal heat exchanger inside your furnace will most likely develop cracks or corrosion over time. They will need to be inspected regularly. Switching to a high-efficiency gas furnace that uses condensing technology significantly lowers exhaust gasses. You can consider installing a heat pump. Heat pumps are another upgrade that will make your home more energy-efficient while protecting against carbon monoxide buildup.
Ensure Proper Venting
The improper functioning of fuel-burning devices in your home can cause excess amounts of carbon monoxide to be released. It is good to know that carbon monoxide buildup in the home can be caused by improper ventilation. Remember, any combustion in a home will release some amount of carbon monoxide. Most household appliances, furnaces, and fireplaces release negligible amounts that are not harmful to human health (under 50 parts per million). However, if your home ventilation system is blocked, those normal carbon monoxide levels will quickly begin to rise.
Fortunately, you can easily avoid this by periodically checking and cleaning the external vents. The clothes dryer vent to your home should be cleaned of lint periodically. And, if your home has a chimney, it's usually a good idea to check once a year to make sure that no birds have built a nest or any other blockage exists, which could reduce proper ventilation.
