Silent Dangers of Carbon Monoxide Poisoning: Know the Signs and Symptoms

Did you know that carbon monoxide poisoning is one of the leading causes of accidental deaths across the United States, even right here in New Albany? Home appliances, like furnaces and heating systems, can play a huge role in the build-up of dangerous levels of carbon monoxide in your home if they’re not functioning properly.

At Allegiance Heating and Air Conditioning, we’re here to keep you safe, 24 hours a day, 7 days a week, 365 days a year. Stay in the know about potential carbon monoxide poisoning with our help.

What is Carbon Monoxide?

Carbon monoxide, deemed as the “silent killer”, is a colorless, odorless, tasteless gas. It is naturally produced by burning gasoline, wood, propane, charcoal, or other fuel. This is a byproduct of burning fuel to heat your home. Improperly ventilated appliances, particularly in a tightly sealed or enclosed space, may allow carbon monoxide to accumulate to dangerous levels, which can quickly become a big problem.

High concentrations of carbon monoxide are often due to improper ventilation or leaking appliances, particularly in a tightly sealed or enclosed space. If your home’s heating system isn’t working properly, you could be putting yourself and family members at risk for carbon monoxide poisoning.

Where does Carbon Monoxide Come From?

Carbon monoxide is a natural byproduct of burning fuel to heat homes here in New Albany and around the country. It is found in fumes produced any time you burn fuel in cars or trucks, small engines, stoves, lanterns, grills, fireplaces, gas ranges, or furnaces.

Our homes are designed to handle this gas and distribute it properly. However, improperly ventilated appliances and engines, particularly in a tightly sealed or enclosed spaces, may allow carbon monoxide to accumulate and become dangerous.

Sources of carbon monoxide in a New Albany home.Household Sources of Carbon Monoxide: Anytime you burn fuel to create heat, you are also creating carbon monoxide. The most common heat sources that create carbon monoxide in the home include:

  • Gas Furnaces
  • Oil Furnaces
  • Oil Boilers
  • Wood Fireplaces
  • Wood Pellet Stoves

When your heating source is running correctly, there is no safety risk of creating heat in your home. However, when the concentration of carbon monoxide displaces the oxygen that our bodies need to function, this can lead to carbon monoxide poisoning. This occurs when there is a breakdown, leak, or malfunction of your heating unit. The most common heating system problems that lead to carbon monoxide poisoning include:

  • Cracks in the combustion chamber
  • Leaks
  • Creaks in the piping
  • Incomplete combustion processes

These types of problems may occur in an older system that has worn down from wear and tear, or a system that has been improperly installed. For help with professional installation of a new home heating system, contact Allegiance Heating and Air Conditioning today!

Symptoms, Signs, & Health Risks of Carbon Monoxide

Carbon monoxide poisoning is caused by inhaling combustion fumes. When there is too much carbon monoxide in the air you’re breathing, your body replaces the oxygen in your red blood cells with carbon monoxide. This means that your oxygen your body needs is not properly reaching your tissues and organs.

This can lead to serious tissue damage and even death. Often times, this happens somewhat slowly. Even when the levels emitted are not high enough to be fatal, it can still produce serious illness.

Some of the most common symptoms of carbon monoxide poisoning to look for include:

  • Dull headache
  • Weakness
  • Dizziness
  • Nausea or vomiting
  • Shortness of breath
  • Confusion
  • Blurred vision
  • Loss of consciousness

Many times, a family member may go to sleep or assume they caught the flu when in reality, they are being subject to carbon monoxide poisoning and the symptoms are starting to persistently take a toll on their body. This can be particularly dangerous when people are sleeping or intoxicated. Sometimes, depending on the level of carbon monoxide present, people may experience irreversible brain damage or even die before anyone realizes there’s a problem.


If you or family members inside your home are experiencing symptoms of possible carbon monoxide poisoning, the first step is to get fresh air. Go outside, get away from the home, and head to the doctor’s office to be tested for carbon monoxide poisoning.

To confirm your diagnosis, the doctor may test a sample of your blood for carbon monoxide. Treatment generally includes breathing pure oxygen to displace the carbon monoxide in your blood, and sometimes hyperbaric oxygen therapy is recommended to speed up the treatment process.

Testing for Poisoning: Our Process

Once you believe your home and family are being threatened by potential carbon monoxide poisoning, there’s no time to waste. Even if you don’t think you’re at risk, regular maintenance checkups and preventative measures can be taken to keep you and your family safe.

During the winter months, homeowners are at a heightened risk for carbon monoxide poisoning. For this reason, a regular, annual heating inspection and maintenance checkup should be a priority in order to ensure proper working equipment and personal safety.
