Carbon monoxide (CO) is a colorless, odorless, and tasteless gas that can pose serious health risks—even be fatal—if it builds up inside your home. Because it’s impossible to detect without proper equipment, protecting your household requires awareness, prevention, and regular maintenance. At Advanced Air Duct Cleaning, we believe education and proactive care are key to keeping families safe. Here’s how you can protect your home from carbon monoxide.

Carbon monoxide is produced when fuels such as gas, oil, propane, wood, or coal do not burn completely. Common sources include furnaces, boilers, water heaters, fireplaces, gas stoves, dryers, and vehicles running in attached garages. When inhaled, carbon monoxide prevents oxygen from reaching vital organs, which can quickly lead to symptoms such as headaches, dizziness, nausea, confusion, and in severe cases, unconsciousness or death.

The most important step in protecting your home is installing carbon monoxide detectors. CO detectors should be placed on every level of your home and near sleeping areas. Test them monthly, replace batteries at least once a year, and replace the entire unit according to the manufacturer’s recommendations—typically every 5 to 10 years.

Fuel-burning appliances must be properly maintained to operate safely. Annual inspections of your furnace, boiler, water heater, and other gas or oil-burning appliances help ensure they are venting properly and burning fuel efficiently. Professional inspections can identify cracked heat exchangers, blocked flues, or other issues that may allow carbon monoxide to leak into your home.

Blocked vents and chimneys are a major cause of carbon monoxide buildup. Debris, animal nests, soot, or snow can prevent exhaust gases from escaping properly. Make sure outdoor exhaust and intake pipes remain clear year-round, and have chimneys inspected and cleaned regularly—especially if you use fireplaces or wood-burning stoves.

Never use ovens, gas stoves, grills, or generators to heat your home. Charcoal grills and portable fuel-burning devices should only be used outdoors, far from windows and doors. Generators should always be operated outside and at least 20 feet away from the home to prevent exhaust from entering indoor spaces.

Vehicles produce carbon monoxide even when running for a short time. Never leave a car running in an attached garage—even with the garage door open. Always turn off vehicles immediately after pulling in, and avoid warming up cars inside the garage.

Adequate airflow helps prevent carbon monoxide from accumulating indoors. Homes that are tightly sealed for energy efficiency can sometimes trap pollutants. Proper ventilation, balanced HVAC systems, and clean ductwork help ensure fresh air circulation and safe exhaust of combustion gases.

If your carbon monoxide detector alarms or you experience symptoms such as headaches, dizziness, nausea, or confusion, leave the home immediately and get fresh air. Call 911 or your local emergency services, and do not re-enter the home until it has been deemed safe.
