Understanding Carbon Monoxide and How It Can Be a Danger in Your Home

Introduction: The Silent Threat Lurking in Atlanta Homes

Carbon monoxide (CO) is an invisible, odorless, and tasteless gas that poses a serious risk to homeowners in Atlanta and across the surrounding suburbs. Known as the "silent killer," carbon monoxide can lead to illness or death without warning. For residents of the Atlanta metro area—from Marietta to Decatur, Sandy Springs to Alpharetta—understanding how carbon monoxide forms, where it can come from, and how to prevent exposure is essential for maintaining a safe and healthy home.

At Reynolds Home and Property Solutions of Georgia, our certified home inspectors regularly identify potential sources of carbon monoxide during residential inspections. We’ve seen firsthand how easily this gas can go undetected in homes lacking proper safeguards. In this in-depth blog post, we’ll explore the hidden dangers of carbon monoxide, how it affects your health, its most common household sources, and the steps you can take to protect your family.

What Is Carbon Monoxide?

Carbon monoxide is a colorless, odorless gas that forms when fuels such as natural gas, propane, oil, wood, or coal do not burn completely. In a well-ventilated and properly maintained system, combustion gases are safely vented outside. However, malfunctions or blockages in these systems can cause carbon monoxide to leak into living spaces.

Common Sources of Carbon Monoxide in Atlanta Homes

The Atlanta housing market features a wide mix of historic homes, mid-century construction, and new builds. Each category comes with its own risks regarding CO exposure. Here are the most common sources of carbon monoxide in homes throughout the Atlanta metro area:

1. Gas Furnaces

Improperly maintained or aging gas furnaces can develop cracks in the heat exchanger or have issues with flue gas venting, which allows carbon monoxide to accumulate indoors.

2. Water Heaters

Gas-powered water heaters are another frequent source. Poor ventilation or backdrafting can allow exhaust gases to enter the home.

3. Fireplaces and Wood Stoves

Inadequate draft, closed flues, or improperly maintained chimneys can result in smoke and CO being pushed back into living spaces.

4. Gas Ovens and Ranges

Leaving a gas stove or oven on for long periods can increase indoor CO levels, especially in small kitchens with limited ventilation.

5. Attached Garages

Running vehicles in attached garages, even with the door open, can flood nearby rooms with carbon monoxide.

6. Portable Generators and Space Heaters

Improper use of generators or fuel-burning heaters indoors is a leading cause of CO poisoning during power outages or winter storms in Georgia.

Why Is Carbon Monoxide Dangerous?

When inhaled, carbon monoxide binds with hemoglobin in your blood, reducing its ability to carry oxygen. This can cause severe tissue damage, unconsciousness, or death within minutes of high-level exposure.

Symptoms of Carbon Monoxide Poisoning

• Headache

• Dizziness

• Nausea or vomiting

• Shortness of breath

• Confusion

• Loss of consciousness

Long-term exposure to lower levels of CO can also result in chronic health issues, such as fatigue and memory problems. Infants, elderly residents, and individuals with heart or respiratory conditions are especially vulnerable.

Atlanta’s Unique Risk Factors for CO Exposure

The humid subtropical climate in Georgia means that homeowners often keep homes tightly sealed during both hot summers and chilly winters. This limited ventilation increases the risk of CO buildup. Additionally, during Atlanta’s occasional winter storms or hurricane-related power outages, the use of backup generators and fuel-burning heaters increases the risk of accidental poisoning.

How to Detect Carbon Monoxide in Your Home

Because carbon monoxide is undetectable by human senses, the only reliable way to identify its presence is through specialized detectors.

Install CO Detectors on Every Level

Place detectors:

• Near all sleeping areas

• On every level of your home

• In basements and near mechanical rooms

Make sure your detectors meet UL (Underwriters Laboratories) safety standards.

Consider Dual Smoke and CO Alarms

For added safety, use combination detectors that monitor both fire and carbon monoxide threats. This is especially beneficial for homes with limited wall space.

Test Detectors Monthly

Like smoke alarms, CO detectors should be tested every month and batteries replaced at least once a year—or as recommended by the manufacturer.

Prevention: How to Minimize Your Risk of Carbon Monoxide Exposure

1. Annual HVAC Inspections

Schedule yearly inspections of your furnace, boiler, and water heater. Reynolds Home and Property Solutions offers detailed HVAC and combustion appliance inspections to ensure safe operation.

2. Maintain Fireplaces and Chimneys

Have chimneys and flues professionally cleaned and inspected annually to prevent blockages and CO intrusion.

3. Ventilation Checks

Ensure that all appliances are properly vented and that venting systems are free of obstructions, rust, or disconnection.

4. Never Run Vehicles or Equipment Indoors

Never start or idle a vehicle, generator, or fuel-burning tool inside an attached garage or closed space—even with doors open.

5. Use Appliances as Intended

Avoid using outdoor appliances like camp stoves or charcoal grills indoors. These are not designed for indoor combustion and pose a serious CO risk.

Real-Life Examples from Metro Atlanta

Case Study #1: Marietta Bungalow An older 1940s bungalow had an original furnace system that lacked adequate venting. After routine inspection, we identified a deteriorating flue pipe. A new high-efficiency system with safe venting was recommended, averting a major health hazard.

Case Study #2: Roswell Rental Property During a pre-listing inspection for a landlord, we found that the water heater in a rental unit was backdrafting due to an improperly sloped flue. This allowed CO to enter the main living area. Repairs and proper vent installation were completed before tenants moved in.

Case Study #3: Alpharetta Remodel A remodeled home had a beautiful open-concept kitchen—but lacked proper ventilation over the gas range. We advised installing a range hood vented to the exterior, significantly reducing CO risk.

Legal Requirements in Georgia Regarding CO Detection

As of current Georgia code:

• New construction must include CO detectors if the home contains fuel-burning appliances.

• Rental properties are required to have functional CO alarms installed in sleeping areas.

• Some municipalities within the greater Atlanta area have additional requirements, particularly for short-term rentals and multi-family buildings.

When to Schedule a Carbon Monoxide Inspection

You should schedule a CO-focused inspection:

• Before purchasing a home

• After renovations or HVAC upgrades

• If your home is more than 10 years old

• If you or family members experience unexplained headaches or fatigue

• If your CO detector alarms go off
