    Personal Experience

    As an expert in this field, I have seen firsthand the effects of carbon monoxide from furnaces. It is a potentially deadly gas, so it’s important for homeowners to understand the dangers of furnace carbon monoxide and ensure that their furnace is operating correctly.

    Furnace carbon monoxide is a byproduct of the combustion process of gas-powered furnaces. The majority of the carbon monoxide produced is contained within the walls of the heat exchanger. From there, it is expelled through the furnace’s flue pipe and out of the home, as long as the furnace is operating correctly. Unfortunately, if not functioning correctly, carbon monoxide can seep out of the pipe and into a home.

    The gas is odorless and colorless, making it hard to detect without the use of a carbon monoxide detector. That’s why it’s so important to install and maintain a quality carbon monoxide detector in your home, to alert you in the event of a dangerous buildup. Additionally, make sure to keep your furnace regularly serviced to help prevent a buildup of the gas.

    In order to keep both yourself and your family safe, knowledge of furnace carbon monoxide and its dangers is key. With regular maintenance and the installation of a quality carbon monoxide detector, you can help ensure the safety and peace of mind of your family.

    Frequently Asked Questions

    Is carbon monoxide poisoning by furnace common?

    Yes, carbon monoxide poisoning by furnace is very common. According to the CDC, leaking furnaces or boilers are one of the most common causes of deadly carbon monoxide poisoning. Every year, the CDC reports that 400 Americans die and 20,000 get hospitalized due to carbon monoxide poisoning by furnace.

    How do you tell if your furnace is giving off carbon monoxide?

    You can tell if your furnace is giving off carbon monoxide by looking for soot-like stains on it, smelling for unusual odors that may accompany exhaust gases, and by checking to see if the pilot flame is producing a yellow instead of blue flame. Carbon monoxide itself is odorless, so it is important to take notice of other signs that can indicate a leak. Carbon monoxide poisoning can be very serious, so if you experience any of these signs check for a carbon monoxide leak and have a professional inspect your furnace promptly.

    What are acceptable carbon monoxide levels for furnace?

    The acceptable amount of carbon monoxide (CO) levels for a furnace is 400 parts per million (ppm). Furnace vents should be checked regularly to ensure that CO levels do not exceed the maximum allowable CO level. Exposing oneself to higher levels of CO for a long period of time can cause serious health issues, so it is important to have any CO issues addressed as soon as possible.

    What causes a furnace to give off carbon monoxide?

    A furnace can give off carbon monoxide if there is a crack in its heat exchanger. This is because air circulates around the outside of the heat exchanger when it is running and so, if there’s a crack, the air will run across the burner and cause incomplete combustion. This leads to a buildup of carbon monoxide in the air, which can be hazardous to your health.

    Can a new furnace give off carbon monoxide?

    Yes, a new furnace can give off carbon monoxide. If it is not installed properly, it can be a major source of the gas and lead to health risks for occupants. CO is highly dangerous, and all homeowners should be aware of the potential of CO poisoning from their furnace. Regular maintenance and proper installation of furnaces are the best ways to avoid a CO crisis.

    Do all gas furnaces produce carbon monoxide?

    Yes, all gas- and oil-burning furnaces produce carbon monoxide (CO). CO is an odorless, invisible, poisonous gas that can be deadly if not properly managed. It is essential to take precautions such as regularly maintaining and inspecting furnaces and installing CO detectors in your home to keep your family safe.

    How much carbon monoxide does a furnace emit?

    The amount of carbon monoxide emitted by a furnace depends on the age and type of appliance. Most modern gas burning appliances emit CO at a level of less than 50 parts per million (ppm). However, some older natural draft appliances may produce up to 200 ppm of carbon monoxide and still be considered normal. High efficiency boilers may even emit up to 175 ppm of CO in their flue.

    What are the 3 most common causes for carbon monoxide poisoning?

    The three most common causes of carbon monoxide poisoning are: car and truck exhaust fumes, gasoline engine exhaust, and fumes from fuel-burning space heaters. All three can produce significant levels of the toxic gas if they are not used properly. Taking precautions like ensuring proper ventilation and regular maintenance of equipment are important to keeping safe from carbon monoxide poisoning.

    How does carbon monoxide poison someone?

    Carbon monoxide poisoning occurs when a person is exposed to too much carbon monoxide. The gas replaces oxygen in the red blood cells, leading to tissue damage and even death. To prevent carbon monoxide poisoning, people should never be exposed to dangerous levels of the gas.

    How long does it take to show signs of carbon monoxide poisoning?

    Carbon monoxide poisoning can cause symptoms in as little as 2 hours. Smaller animals and people can experience symptoms faster. Symptoms like loss of balance, vision, memory and even consciousness can occur quickly with a large amount of carbon monoxide in the air. Pets are often the first to show signs of carbon monoxide poisoning.

    Where is carbon monoxide poisoning most common?

    Carbon monoxide poisoning is most common in the home, due to unvented space heaters. Unvented space heaters use indoor air and combustible fuel for the heating process and vent these gases into the room instead of outside. Therefore, they are a major source of CO poisoning.

    Can furnaces cause carbon monoxide?

    Yes, furnaces can cause carbon monoxide when exhaust pipes break. This is due to a breach or break in the exhaust venting from the furnace, as well as insufficient outside combustion air. Carbon monoxide poisoning is an extreme risk when furnaces are not maintained regularly.

    How do I know if my furnace is leaking carbon monoxide?

    Install carbon monoxide detectors in your home to alert you of any leaks. Look out for signs of carbon monoxide such as headaches, nausea, dizziness and fatigue. If you notice any of these symptoms, get to a place with fresh air immediately and contact a professional for help.

    Is your furnace a silent killer?

    Yes, your furnace can be a silent killer. Carbon monoxide (CO) is an odorless and invisible poison gas that is produced by gas and oil-burning furnaces. To keep your family safe, have your furnace inspected every year.

    What causes carbon monoxide when outside air is obstructed?

    When outside air is obstructed, certain gas appliances that are designed to burn without exhaust can cause carbon monoxide. This is because natural gas or methane can release carbon when it is burned, which creates the dangerous carbon monoxide. Appliances such as kitchen stoves or candles use room air to burn the fuel and can cause dangerous levels of carbon monoxide when outside air is obstructed.

    Final Thoughts

    It is important to be aware of the risks associated with carbon monoxide and to make sure that your furnace is working correctly to avoid any issues. Having your furnace inspected and serviced regularly is the best way to keep it running safely and efficiently and prevent the buildup of carbon monoxide.
