Winter is in full swing across the Tri-Lakes area, and your furnace is working overtime to keep your family warm through these cold Ozarks nights. But there’s an invisible danger that comes with heating season, one that sends over 100,000 Americans to the emergency room every year and causes around 400 deaths annually. We’re talking about carbon monoxide poisoning.
As your local HVAC experts serving Branson and the surrounding communities for over 40 years, we want to make sure every homeowner understands this silent threat and knows how to protect their family.
What Makes Carbon Monoxide So Dangerous?
Carbon monoxide (CO) is called “the silent killer” for good reason. It’s completely colorless, odorless, and tasteless. You can’t see it, smell it, or taste it. Unlike natural gas, which has that distinctive rotten egg smell added intentionally, carbon monoxide gives you absolutely no warning.
When you breathe in CO, it binds to your blood’s hemoglobin 200 to 250 times more readily than oxygen does. This means your blood starts carrying carbon monoxide instead of oxygen, starving your brain, heart, and other vital organs. The symptoms mimic the flu (headache, dizziness, nausea, fatigue), so many people don’t realize they’re being poisoned until it’s too late.
Common Sources in Your Home
Any fuel-burning appliance can potentially produce carbon monoxide, especially if it’s not properly maintained or vented. The most common culprits we see here in the Tri-Lakes region:
Gas furnaces are the number one source during winter. A cracked heat exchanger, blocked vents, or incomplete combustion can all lead to CO buildup inside your home.
Water heaters that run on gas or propane need proper venting. If the vent gets blocked, carbon monoxide has nowhere to go but back into your living space.
Attached garages are surprisingly dangerous. Running your car to warm it up (even with the garage door open) can allow exhaust to seep into your house.
Portable generators have become more common with our occasional winter storms. Never run a generator inside your home, garage, or even on a covered porch. They need to be at least 20 feet away from windows, doors, or vents.
Warning Signs to Watch For
The tricky part about carbon monoxide poisoning is that the symptoms look like a lot of other things. Common early symptoms include headache, dizziness, weakness, nausea, chest pain, and confusion. Many people describe it as feeling “flu-like,” but here’s the key difference: if everyone in your household feels sick at the same time, especially when you’re all at home, that’s a major red flag.
Your furnace also gives you a visual warning sign. The flame should always burn blue. If you notice a yellow or orange flame, that indicates incomplete combustion, which means carbon monoxide is being produced. Shut the system down immediately and call us at (417) 335-2512.
Other warning signs include soot or scorch marks around your furnace, excessive moisture on windows near gas appliances, or your pilot light keeps going out.
Carbon Monoxide Detectors: Your First Line of Defense
Installing CO detectors throughout your home is absolutely essential. They’re inexpensive, easy to install, and they save lives. Here’s where you need them:
Install at least one detector on every level of your home, including the basement. Place detectors outside every sleeping area. If you can only afford one detector, put it in the hallway near the bedrooms and make sure it’s loud enough to wake everyone up.
Install a detector near your attached garage and one near your furnace room or any area with fuel-burning appliances (but not right next to them, stay at least 15 feet away to avoid false alarms).
Avoid placing detectors in bathrooms or overly humid areas, right next to windows or vents, or in dead-air spaces like corners of vaulted ceilings.
What to Do If Your Detector Goes Off
If your carbon monoxide detector sounds, take it seriously every single time. Get everyone out of the house immediately, including pets. Once you’re safely outside, call 911. Don’t go back inside until emergency responders tell you it’s safe.
If anyone is experiencing symptoms (especially confusion, dizziness, or difficulty staying conscious), tell the 911 operator immediately. They may need immediate medical treatment.
After the emergency is resolved, call us at (417) 335-2512. We’ll inspect your furnace and heating system, identify the source of the carbon monoxide, and make the necessary repairs to ensure your home is safe.
Prevention Through Maintenance
Most carbon monoxide incidents are completely preventable with proper HVAC maintenance. During a professional furnace tune-up, our NATE-certified technicians:
- Inspect your heat exchanger for cracks or damage
- Examine all venting and flue pipes to make sure they’re not blocked
- Check the combustion chamber and burners for proper flame color
- Test carbon monoxide levels to verify your system isn’t producing dangerous amounts
- Verify that all safety controls are working properly
These inspections catch problems before they become dangerous. A crack that’s just starting in your heat exchanger might not be producing CO today, but it will in a few months. Regular maintenance finds these issues early.
Special Considerations for Tri-Lakes Homeowners
If you own a vacation home around Table Rock Lake, Bull Shoals, or Lake Taneycomo that sits empty for weeks at a time, consider installing smart detectors that alert you via your phone.
Our winter weather can also create unexpected CO hazards. Ice and heavy snow can block furnace vents and chimneys. After major storms, check that all outdoor vents are clear.
If your furnace is 15 years or older, you’re in the higher-risk category for carbon monoxide issues. Heat exchangers crack with age, seals deteriorate, and components wear out. Modern high-efficiency furnaces have better safety features and more reliable combustion.
Your Action Plan Right Now
Check that you have working CO detectors on every level of your home. Test them using the test button.
Look at your furnace’s flame color. If it’s anything other than blue, call us immediately.
If your furnace hasn’t been professionally serviced in over a year, schedule maintenance now. Don’t wait until something goes wrong.
Walk around outside and check that all your furnace vents are clear of snow, ice, leaves, or debris.
