When Winter Strikes and Your Heat Fails: The Hidden Danger That Could Turn Deadly in Minutes

Winter HVAC emergencies are stressful enough without the added threat of carbon monoxide poisoning, but most CO exposures happen in the winter in cold climates, with more than 50,000 people visiting emergency rooms because of accidental CO poisoning each year. When your heating system breaks down during the coldest months, the desperate search for warmth can inadvertently create life-threatening conditions that claim hundreds of lives annually.

The Silent Killer Strikes When You’re Most Vulnerable

Carbon monoxide is a colorless, odorless, tasteless gas made when fuel burns, formed by the incomplete combustion of fuels, and since CO has no odor, color or taste, it cannot be detected by our senses. This invisible threat becomes particularly dangerous during winter heating emergencies when homeowners resort to alternative heating methods or when damaged HVAC systems malfunction.

According to the CDC, more than 400 Americans die yearly from carbon monoxide poisoning, with 20,000+ visiting the emergency room, and 4,000 people hospitalized each year from inhaling the deadly gas. Carbon monoxide (CO) poisoning can become deadly in a matter of minutes, and when high levels of CO enter your body, it can be deadly after only a few minutes.

How Winter HVAC Breakdowns Create Deadly Scenarios

When heating systems fail during winter, several dangerous situations commonly arise:

• Cracked Heat Exchangers: Another culprit of carbon monoxide poisoning is if the heat exchanger on your furnace becomes cracked. This component works like your car exhaust. Without the exchanger pushing fumes out, they are blown back inside your home.
• Blocked Ventilation: Blocked vents or chimney flues is another common cause of carbon monoxide leaks. Your ventilation system is designed to move the deadly gases out of your building, but can get clogged by years-worth of dust and debris.
• Emergency Heating Alternatives: The very common source of CO poisoning is unvented space heaters in the home. An unvented space heater uses combustible fuel and indoor air for the heating process. A space heater that is not installed right or not working correctly can release CO and other toxic fumes into the room.
• Incomplete Combustion: Carbon monoxide happens when your furnace doesn’t burn gas completely. Normal combustion turns fuel into carbon dioxide and water vapor. But when the burners don’t work properly, not all of the gas turns into carbon dioxide and some of it becomes carbon monoxide.

Recognizing the Warning Signs Before It’s Too Late

Identifying CO poisoning can be difficult because the symptoms are similar to the flu. CO is often called the “silent killer” because people will ignore early signs and eventually lose consciousness and be unable to escape to safety.

Early symptoms include:

• Headache, dizziness, weakness, nausea and vomiting, rapid heartbeat, shortness of breath, seizures, chest pain, disorientation, and loss of consciousness
• For most people, the first signs of exposure include mild headache and breathlessness with moderate exercise. Continued exposure can lead to more severe headaches, dizziness, fatigue and nausea

When Emergency Strikes: Immediate Action Steps

If you suspect carbon monoxide poisoning during a heating emergency:

1. CO poisoning needs to be treated right away by getting outside to fresh air and calling 911
2. Get people and pets out of the house and into the fresh air
3. Don’t reenter your home until local emergency services tell you it’s safe to do so. There still may be CO fumes in your home
4. Contact a professional HVAC service immediately for emergency repairs

Prevention: Your Best Defense Against Winter CO Emergencies

The key to preventing carbon monoxide emergencies during winter breakdowns lies in proactive maintenance:

• Have your furnace and fireplace cleaned and checked before each heating season
• We recommend scheduling a furnace tuneup annually in the fall to ensure your heating system is working as intended. In addition to checking your furnace function, an HVAC technician will make sure it’s ventilating properly
• Regular and professional maintenance of your HVAC system is a cornerstone of home safety, especially as it concerns carbon monoxide poisoning. A faulty HVAC system can be a hidden danger, potentially causing a buildup of carbon monoxide within your home. This can occur if there are leaks, blockages or problems with the system’s ventilation
• Gas heating systems may produce dangerous levels of carbon monoxide (CO), an odorless, colorless, tasteless that is toxic to humans and animals. We will test the CO levels in your home and take any necessary steps to reduce them

Essential Safety Equipment

Safety should always be paramount when it comes to your family and home, and one of the best ways to ensure this is by installing carbon monoxide (CO) detectors. CO is a colorless and odorless gas, making it nearly impossible to detect without a sensor. High concentrations of this gas can be fatal, hence the need for these life-saving devices. CO detectors, when installed correctly and in critical locations, will sound an alarm if CO levels become dangerous.

However, carbon monoxide detectors can ONLY detect extremely high levels of carbon monoxide. Carbon monoxide detectors fail to detect smaller, yet still potent levels of the dangerous gas. Chronic exposure to those low levels of carbon monoxide can lead to the same dangerous, life-changing symptoms as acute exposure. Your furnace can be leaking carbon monoxide into your home for weeks, and your carbon monoxide detectors could miss it.

The Bottom Line: Don’t Gamble with Your Family’s Life

In all cases, you’re better safe than sorry when dealing with carbon monoxide. Enlist the help of a local professional to ensure your home heating system keeps your family safe and warm through the winter. When winter HVAC emergencies strike, the combination of desperation for warmth and potentially malfunctioning equipment creates a perfect storm for carbon monoxide poisoning.

Remember, carbon monoxide poisoning is entirely preventable with proper maintenance, professional emergency services, and appropriate safety equipment. Don’t let a winter heating emergency become a family tragedy – prioritize both warmth and safety by working with qualified HVAC professionals who understand the critical importance of carbon monoxide safety during emergency repairs.
