Understanding Carbon Monoxide Risks in the Home

As a real estate agent, your role extends beyond just helping clients find the right property — you're also a trusted advisor during one of the biggest financial decisions of their lives. One critical topic that often goes overlooked is carbon monoxide (CO) safety. Understanding how to recognize CO risks and discuss them with clients can protect their health and even save lives.

What Is Carbon Monoxide?

Carbon monoxide is a colorless, odorless, and tasteless gas that is produced whenever fuel is burned — including natural gas, propane, wood, charcoal, and oil. It's extremely dangerous and can be lethal at high concentrations, earning it the nickname “the silent killer.”

Common Sources of CO in Homes

• Gas furnaces and water heaters
• Fireplaces (especially unvented or improperly vented units)
• Gas stoves and ovens
• Attached garages (idling cars)
• Portable generators and space heaters
• Clogged chimneys or vents

Why CO Awareness Matters for Agents

Carbon monoxide is not just a safety issue — it's a liability issue. Educating your buyers and sellers about CO risks can set you apart as a knowledgeable and trustworthy professional. In some states, it's required that CO detectors be installed prior to closing. Knowing these rules helps avoid delays and protects your clients.

CO Detectors: What to Look For

CO detectors should be installed on every level of a home, especially outside sleeping areas. Many newer models are combination smoke/CO detectors. Remind clients to:

• Test detectors monthly
• Replace batteries twice a year (unless sealed 10-year batteries are used)
• Replace the units themselves every 5–7 years

How Home Inspectors Can Help

Modern inspection companies like Inspections Over Coffee go beyond basic checklist inspections. We carry calibrated CO detectors to check for unsafe levels of carbon monoxide at key locations in the home, and include those results in the inspection report.

We also use thermal imaging to detect incomplete combustion and possible air leaks around gas appliances, helping identify conditions that could lead to CO buildup before they become dangerous.

Talking Points for Buyers and Sellers

• “Have you checked the expiration dates on your CO detectors?”
• “Are there CO detectors near all bedrooms and fuel-burning appliances?”
• “Would you like your inspector to carry a CO tester for added peace of mind?”
• “Do you know what CO poisoning symptoms look like and how to respond?”

Symptoms of CO Poisoning

Educate your clients on the signs of carbon monoxide poisoning:

• Headache
• Dizziness
• Nausea or vomiting
• Confusion
• Shortness of breath
• Unconsciousness (in severe cases)

If CO poisoning is suspected, clients should leave the home immediately and call 911.

Set Yourself Apart

Clients expect more than paperwork and showings — they expect protection and advocacy. Understanding CO risks and partnering with an inspector who uses advanced detection tools helps you deliver that value. At Inspections Over Coffee, we’re here to help make you the hero in every transaction.
