Quick Answer
A cracked heat exchanger can leak carbon monoxide into your home’s air. In Steubenville, exchanger-only repairs usually cost $1,500–$4,000, while full furnace replacements average $2,600–$5,600. Because of the safety risk and long labor time, most homeowners choose a complete replacement for peace of mind and warranty protection.
Why Furnace Safety Matters in Steubenville
Steubenville’s hillside homes, Ohio River humidity, and older basements make furnaces work harder than most. Houses along Pleasant Heights, Market Street, and University Boulevard often rely on aging gas systems and outdated venting. Moisture and poor airflow accelerate metal fatigue and corrosion. Recognizing furnace warning signs early helps prevent exposure to carbon monoxide and avoids emergency replacements during winter freezes.
How a Cracked Heat Exchanger Turns Dangerous
Inside every gas furnace, the heat exchanger separates combustion gases from indoor air. When that chamber cracks, exhaust can leak into the air stream. In Steubenville’s below-grade basements and river-adjacent homes, trapped CO can build quickly. Warning signs include metallic odors, soot marks, and flames that flicker yellow instead of steady blue. CO detectors near bedrooms and annual system checks are essential for safety.
Repair or Replace?
Replacing the exchanger alone requires full furnace disassembly and up to ten labor hours, often costing nearly half the price of a new unit. Because many local furnaces are 10–15 years old, upgrading to a high-efficiency model is usually smarter. New 90%+ AFUE systems lower gas bills and qualify for AEP Ohio rebates. Honest Fix provides exact quotes, visual proof, and Service Guardian coverage so homeowners know the job was done right.
FAQs
Q: What should I do if my CO detector sounds near the furnace?
Shut the unit off, ventilate your home, and call 911. Once cleared, contact a licensed technician for inspection.
Q: Why are older Steubenville homes more at risk?
Many pre-1950 basements have poor airflow and unlined brick flues. These conditions let CO linger and speed corrosion inside older furnaces.
