What Is Carbon Monoxide And How Can You Keep Your Home Safe?

Carbon monoxide (CO) is a colorless, odorless gas that poses a serious threat to your family and home. It forms when fuel—like gas, oil, wood, or charcoal—burns without enough oxygen. Common household sources include furnaces, water heaters, stoves, fireplaces, and even idling vehicles in garages. CO interferes with your body’s ability to absorb oxygen, causing mild symptoms like headaches and nausea, and in high doses, can lead to unconsciousness or death. Every year, hundreds of Americans die and thousands are hospitalized due to accidental CO exposure.

Keep reading to learn more, and how Wythe Home Services can provide you with the necessary HVAC maintenance to help reduce levels of CO in your home.

What Is Carbon Monoxide and Why Is It Dangerous

When CO enters your bloodstream, it forms compounds with hemoglobin that reduce your body’s capacity to transport oxygen. Even low-level exposure—around 100 parts per million (ppm)—can cause headaches after just a couple of hours. As levels rise (400 ppm within an hour, or 1,600 ppm in 20 minutes), so does the danger: dizziness, confusion, heart issues, and eventually, failure of vital systems. What’s even more concerning is that CO symptoms often mimic the flu—chest pain, fatigue, vomiting, and dizziness, but without fever. If your symptoms fade when you step outside, CO may be the hidden culprit.

Common Signs of CO Poisoning

Watch for symptoms like persistent headaches, nausea, dizziness, shortness of breath, chest tightness, fatigue, and mental fogginess. In severe cases, people may experience loss of consciousness, arrhythmia, or seizures. Since CO symptoms can look like a virus or allergy, it’s especially alarming when multiple people in the home fall ill or symptoms improve outdoors.

Where to Install CO Detectors and Which Ones to Buy

The right detector can save your life, but where it’s placed is just as important:

• One detector per floor, including basements and attics.
• Near each bedroom, ideally within 10–20 feet of sleeping areas.
• At breathing level: roughly 3–5 feet above the floor, or on a shelf—CO mixes evenly with air.
• Avoid installations close to windows, vents, or fuel-burning appliances; follow manufacturer instructions closely.

Choose UL-2034 certified detectors, preferably with digital readouts and interconnected units so that all alarms trigger at once.

Maintaining Your CO Detectors

Even the most advanced alarm isn’t effective if neglected:

• Test them monthly using the test button.
• Replace batteries annually—a good reminder is daylight saving time.
• Clean them weekly by gently wiping off the dust.
• Replace outdated units every 5 years, or sooner if the manufacturer recommends.

Maintaining your detectors ensures reliable alerts and early detection.

Preventing CO Leaks with Regular HVAC & Furnace Maintenance

Fuel-burning systems, especially furnaces, and water heaters, are frequent sources of CO leaks. That’s why professional, annual HVAC maintenance matters:

• Certified technicians carry out a combustion analysis, checking for efficient, safe fuel burning and proper venting.
• They inspect heat exchangers for cracks, clean flues and chimneys, and test exhaust safety with specialized CO meters.
• Frequency: every year for all gas, oil, propane, or wood-burning appliances.

This proactive approach catches small issues—like blocked vents or tiny cracks—before they spiral into dangerous CO leaks.
