Carbon Monoxide Safety: Post-Ice Storm HVAC Checks in Asheboro
By Jordan Heating and Air | Serving Central North Carolina Since 1928
TL;DR | ESTIMATED READING TIME: 2 MIN
Ice buildup can block furnace exhaust vents or damage heat exchangers. If you used a portable generator or your gas furnace struggled during the storm, verify your detectors are working and schedule a professional inspection to prevent carbon monoxide poisoning.
The Hidden Risk After the Freeze
The recent ice storm forced many Asheboro heating systems to run at maximum capacity for days. If your system requires a Furnace Repair, a cracked heat exchanger or a blocked flue pipe could allow odorless carbon monoxide (CO) to enter your living space. Power outages also lead to the use of portable generators; if placed too close to windows or intake vents, exhaust can pull back into your home.
Critical HVAC Carbon Monoxide Safety Indicators.
Venting Obstructions: Heavy ice or fallen limbs can crush or clog the PVC or metal pipes that exhaust fumes outside your home.
Yellow Pilot Light: A healthy furnace flame is blue. A yellow or flickering flame suggests improper combustion and potential CO production.
Detector Age: Most CO detectors expire after five to seven years. If yours chirped during the storm, it may be end-of-life rather than a low battery.
Post-Storm System Audit
| System Factor | Your Current Situation | What That Usually Means |
|---|---|---|
| Exhaust Flue | Ice or debris visible around the pipe | Potential for exhaust backup into the attic or home |
| Furnace Sound | Loud booming or rattling on startup | Delayed ignition or cracked heat exchanger risk |
| CO Detector | Unit is more than 5 years old | Sensor may be unreliable and requires replacement |
Managing the Tradeoff: Comfort vs. Safety
When the power returns, the instinct is to crank the heat to 72 degrees immediately. However, a system that has been frozen or strained may have developed hairline fractures in the heat exchanger. The heat exchanger is the metal wall between the burning gas and the air you breathe. If this wall fails, the "tradeoff" isn't just a higher bill; it is a life-safety issue.
Our technicians use calibrated digital analyzers to measure CO parts per million (PPM) within your ductwork. We check the manifold pressure and the vent draft to ensure the combustion cycle—from the gas valve to the chimney cap—is sealed and flowing correctly.

Frequently Asked Questions
How do I know if my furnace is leaking carbon monoxide?
You cannot see or smell carbon monoxide. Physical symptoms include headaches, dizziness, or nausea—often described as "flu-like" symptoms. For a complete list of health indicators and safety protocols, refer to the CDC Carbon Monoxide Safety Guide. The only reliable way to detect a leak in your home is through functioning CO detectors and a professional carbon monoxide check on your HVAC system in Asheboro or surrounding areas.
Where should I place my generator to avoid CO buildup?
Keep portable generators at least 20 feet away from your home. Ensure the exhaust is pointed away from all doors, windows, and HVAC fresh-air intakes. Never run a generator in a garage, even with the door open, as fumes can linger in Liberty homes.
Does a furnace tune-up include a CO test?
Yes, a standard Jordan Heating and Air safety inspection includes a visual check of the heat exchanger and a combustion analysis. This ensures your system in Seagrove is venting properly and that the fuel-to-air ratio is balanced for safe operation.
If you suspect your system was damaged by the ice or if your CO detector is alerting, turn off your gas and open your windows immediately. Our uniformed technicians are ready to perform a comprehensive safety audit to keep your family protected.
