As the temperatures drop and heaters fire up, it’s the perfect time to talk about an important safety issue: carbon monoxide (CO). Known as the “silent killer,” carbon monoxide is a colorless, odorless gas that can be deadly if it builds up inside your home. At De Hart Plumbing, Heating & Cooling, your family’s safety is our top priority — so we want to help you understand what carbon monoxide is, where it comes from, and how to protect yourself this heating season.
What Is Carbon Monoxide?
Carbon monoxide is a toxic gas produced when fuels like natural gas, propane, wood, oil, or coal don’t burn completely. Because it’s invisible and odorless, you usually can’t tell it’s present until symptoms appear — which is why detectors and regular maintenance are critical.
Common Sources of CO in Homes:
- Gas furnaces and boilers
- Gas water heaters
- Fireplaces and wood stoves
- Gas ranges or ovens
- Vehicles running in attached garages
- When these appliances are properly vented and maintained, CO levels stay safe. But leaks, blocked vents, or faulty equipment can cause dangerous buildups.
CO poisoning can look like the flu but without a fever. Common symptoms include:
- Headaches
- Dizziness
- Nausea or vomiting
- Shortness of breath
- Confusion
If several people in your home feel sick at the same time, especially during heating season, get fresh air immediately and call 911.
How to Protect Your Family:
- Install Carbon Monoxide Detectors – Place them on every level of your home, especially near bedrooms.
- Schedule Annual Heater Maintenance – A trained technician can inspect your system for cracks, leaks, and venting issues.
- Keep Vents Clear – Snow, leaves, or debris can block exhaust vents and trap CO inside.
- Never Run Engines Indoors – Even for a short time, cars or generators can quickly build up dangerous CO levels.
