What Is Carbon Monoxide
Carbon monoxide (CO) is a colorless, odorless, and tasteless gas and is one of the most acutely toxic substances. It is produced as a byproduct when fuels are burned, such as natural gas, coal, kerosene, wood, and propane.
Carbon monoxide can feel like a non-issue, as it is colorless and odorless. Breathing it in can pose dangerous health hazards. Its capacity to remain undetected by human senses has contributed to its widely-used moniker “silent killer.
Even low levels of exposure can cause life-threatening health complications, and prolonged or high exposure levels can be deadly. Each year, more than 400 Americans die from accidental CO poisoning. This statistic serves to remind us all of the deadly danger that CO poisoning presents to our communities.
Why It Is Called The Silent Killer
Carbon monoxide is known as the silent killer, as there are no immediate warning signs to let you know it’s in the air. Unlike natural gas leaks, which can be detected by their rotten egg smell, CO is impossible to detect without specialized gear such as CO alarms.
In enclosed spaces, it can build up over time to lethal concentrations without anyone noticing. This frequently occurs when appliances such as gas stoves or water heaters are not properly vented or maintained. Understanding these risks is essential.
Too often, cases of CO poisoning occur simply because individuals are unaware of how quickly and easily it can build up in their homes.
How It Affects Your Health
Once inhaled, carbon monoxide inhibits the body’s capacity to carry oxygen. It does this by binding to hemoglobin in red blood cells, blocking oxygen from getting to essential organs such as the brain and heart.
Exposure can lead to other nonspecific symptoms. You may feel the first, mild effects including headaches and dizziness or more severe reactions including confusion, chest pain and loss of consciousness.
Severe exposure to CO may cause permanent injury to organs or even death. Identifying symptoms as soon as they appear is key, as late treatment can lead to a more difficult recovery process.
Common Sources In Your Home
From appliances to vehicles, there are many potential sources of carbon monoxide—especially if they’re misused or poorly maintained. Common sources include gas stoves, furnaces, and fireplaces—often when ventilation is poor.
A broken furnace, for instance, could cause CO to seep into your home, endangering every person inside. Portable generators and gas-powered tools, when used indoors, are major hazards.
Even something as mundane as burning wood in a fireplace can cause CO to accumulate if the chimney is not properly maintained. Routine inspection of appliances and proper ventilation can help prevent leaks.
How HVAC Systems Can Leak Carbon Monoxide
Carbon monoxide (CO) leaks in HVAC systems can be hard to detect until they become life-threatening hazards. Understanding how these systems can become leaky in the first place is essential for keeping your home safe. HVAC systems, especially older or poorly-maintained systems, can produce conditions that allow carbon monoxide to leak into your home.
Read on below as we explore more about what causes these leaks and how they happen.
Causes of Carbon Monoxide Leaks
There are a number of reasons why HVAC systems leak carbon monoxide. As with any equipment, wear and tear over time is inevitable, and aging components, such as heat exchangers, are more likely to crack. These fissures create an opening for CO, a byproduct of furnace combustion, to leak through.
Blocked vents is a frequent problem, as blocked vents force dangerous gases that should vent to the outside into people’s homes. Severe weather, like heavy snow, can cover outside exhaust outlets, worsening this danger.
Faulty Equipment and Poor Maintenance
Regular maintenance is critical for keeping your HVAC system safe. Neglect can lead to rust, corrosion, or cracks in vital components, which create pathways for CO leaks. Routine inspections by trusted professionals, like those at Cummings Plumbing Company, ensure early detection of such problems.
Annual inspections support system efficiency and reduce safety hazards.
Improper Installation or Ventilation
Illegal HVAC installations put your system at risk of leaking harmful combustion gases such as carbon monoxide. If ventilation systems are poorly designed, the CO can get trapped inside, which can lead to life-threatening situations.
DIY installations are cheaper but they do not have professionally trained eyes overseeing them and usually come with built-in dangers. To keep your home safe from carbon monoxide, HVAC systems must be properly installed and maintained by licensed professionals.
Signs Your HVAC System Is Leaking
Plus, HVAC-related carbon monoxide leaks can be particularly insidious. If you know the signs of an impending leak, you can take action to save a life. Whether it’s the smell of something burning or you’re experiencing new, unexplained physical symptoms, something is off and it’s important to listen to these warning signs.
Signs of a carbon monoxide leak Below, we explain how to recognize these all-too-common signs of a CO leak.
1. Unusual Odors From The System
Unusual odors emitting from your HVAC system usually indicate an issue. Carbon monoxide is odorless, but don’t ignore the smells that go along with it. A burning, gas, or musty smell is an indicator that something is wrong within the system.
These smells can be caused by overheating parts or improper gas combustion. Catching unusual smells quickly protects the HVAC system from additional harm and keeps your home from potential dangers.
2. Soot Or Stains Around Vents
Soot or dark streaks around registers are indicators of combustion issues. These black marks are the result of incomplete combustion of fuel, which can lead to the release of toxic gases, such as carbon monoxide.
Making a habit of inspecting vents for dark stains is a simple method to detect early indicators of leaks before they develop into more serious issues.
3. Yellow Or Flickering Pilot Light
A healthy, functioning pilot light should burn blue. If your flame looks yellow or flickering it indicates improper combustion, which can create carbon monoxide.
In these cases, a professional inspection by an HVAC technician protects your health and addresses the cause of the problem.
4. Increased Condensation On Windows
Condensation on windows might indicate an issue with ventilation in your home. Both poor airflow and poor combustion efficiency raise humidity, which is an unsafe byproduct associated with carbon monoxide.
Keeping tabs on condensation levels helps ensure a safer indoor environment.
