Carbon monoxide poisoning is a serious but often overlooked risk for many homeowners in Lubbock. Known as the “silent killer,” this gas is colorless, odorless, and deadly if left undetected.
At Lowery Plumbing, Heating, and Air Conditioning, we prioritize your family’s health and safety—offering 24/7 emergency HVAC services and expert guidance on how to protect your home from hidden dangers. One of the most important safety steps you can take is to understand the signs of carbon monoxide poisoning and how to prevent exposure to this dangerous gas.
What Is Carbon Monoxide and Where Does It Come From?
Carbon monoxide in homes typically comes from appliances that burn fuel, like gas furnaces, gas stoves, water heaters, a blocked chimney, and generators. When these systems are improperly vented, malfunction, or used in enclosed spaces, carbon monoxide can accumulate to dangerous levels. It’s a natural byproduct of incomplete combustion and can be released from common household items like:
- Gas stoves and ovens
- Fireplaces, especially when the flue or chimney is blocked
- The furnace and other heating systems
- Boilers, space heaters, and kerosene heaters
- A vehicle left running in an attached garage
In colder months, Lubbock residents rely more on central heating, which increases the risk of carbon monoxide buildup. Improper ventilation, a cracked heat exchanger, or blocked dryer vents can all contribute to carbon monoxide leaks. That’s why it’s critical to schedule regular HVAC maintenance and install carbon monoxide detectors throughout your home.
Carbon Monoxide Poisoning Symptoms
Carbon monoxide poisoning symptoms often mimic influenza or foodborne illness, making it easy to overlook the danger. When you breathe in carbon monoxide, it binds to the hemoglobin in your red blood cells, forming carboxyhemoglobin, which reduces the amount of oxygen delivered throughout the body. This can lead to severe tissue damage and even death.
If multiple people in your home experience the following symptoms at the same time, especially without a fever, it’s time to take action:
- Headache
- Dizziness or confusion
- Nausea or vomiting
- Fatigue or weakness
- Shortness of breath
- Chest pain
- Amnesia or fainting
Prolonged, severe exposure can lead to loss of consciousness, organ damage, seizure, cardiac arrest, or death. If you suspect a carbon monoxide leak, get everyone outside immediately and call 911.
Who is Most at Risk of Carbon Monoxide Poisoning?
Carbon monoxide poisoning can affect anyone, but certain individuals are more vulnerable to serious complications, even at lower levels of exposure. Those at heightened risk include:
- Infants and young children, due to their developing lungs and nervous systems
- Pregnant women, as reduced oxygen levels can impact the fetus
- Older adults, especially those with weakened respiratory or cardiovascular systems
- People with chronic conditions such as heart disease, anemia, or hypertension
- People with lung conditions, like asthma or COPD
If someone in your household falls into one of these categories, it’s especially important to have working carbon monoxide detectors and schedule regular HVAC inspections to reduce the risk of exposure.
Early Warning Signs of a Carbon Monoxide Leak in Your Home
Beyond physical symptoms, there are a few signs of carbon monoxide poisoning that may show up in your home before you begin to feel unwell:
- Stale or stuffy air, especially around fuel-burning appliances
- Soot or brown-yellow stains near appliances
- Pilot lights that frequently go out
- Visible blockages in the flue, chimney, or exhaust system
- Unusual, smoky odor (note: carbon monoxide has no smell, but smoke, gas, or other byproducts may)
If you notice any of these signs, shut off your appliances and contact an HVAC professional right away.
Common Causes of Carbon Monoxide Leaks
Carbon monoxide poisoning incidents often stem from avoidable mistakes or lack of maintenance. Do not:
- Use a gas oven or stove to heat your home
- Burn wood, coal, or charcoal indoors without proper ventilation
- Operate a space heater, generator, or kerosene heater in a closed basement, tent, or garage
- Run a vehicle inside a garage, even with the garage door open
All of these can trap carbon monoxide and smoke indoors, putting you at serious risk.
How to Prevent Carbon Monoxide Poisoning
Fortunately, preventing carbon monoxide exposure is very manageable with a few simple steps and proper awareness. Here’s what you should do to protect your home, respiratory system, and overall health and safety:
- Schedule annual HVAC maintenance: Furnaces, water heaters, and gas fireplaces should be inspected by a certified technician every year to ensure proper ventilation and function.
- Install carbon monoxide detectors: Place one on every level of your home, especially near sleeping areas and any cooking areas. Make sure the alarms are not covered by furniture or curtains. Test the batteries monthly and replace detectors every 5–7 years.
- Ensure proper ventilation: Make sure your home’s ventilation system is working efficiently and that air can flow freely from appliances to the outside.
- Educate your family: Teach your family about the importance of indoor air quality, proper ventilation, and first aid in the event of exposure.
If your carbon monoxide alarm does go off, immediately get your family outdoors and call 911. Stay in a safe location until emergency responders determine your home is safe to reenter.
If you’re unsure about your current setup, a professional HVAC technician can inspect your ventilation systems, install and test carbon monoxide detectors, and ensure your indoor air quality is safe.
What to Do in an Emergency
If you believe you or a family member is experiencing carbon monoxide poisoning symptoms, leave the house immediately and call 911. Avoid stopping to open windows or gather belongings, as unconsciousness or brain injury can happen very quickly due to reduced oxygen levels. After emergency services have been contacted, call a heating and air professional who can identify and fix the source of the leak.
