Quick Answer
A cracked heat exchanger is one of the most dangerous furnace problems a homeowner can face. In Follansbee, exchanger-only repairs typically cost $1,500–$4,000, while complete furnace replacements range $2,600–$5,600. Because cracks can leak carbon monoxide, replacing the entire furnace is the safest and most cost-effective long-term option.
Why Furnace Safety Matters in Follansbee
Follansbee’s riverside air, steep hills, and older mill homes make local furnaces work overtime. Humidity from the Ohio River speeds rust and corrosion inside metal exchangers. Many homes near Allegheny Street and Hooverson Heights were built before modern ventilation standards, and their smaller basements often limit airflow. Combined with heavy winter use, these conditions can turn minor cracks into major safety issues. Regular inspections keep Follansbee families safe through freezing months.
How Cracks Create Carbon Monoxide Risks
The furnace heat exchanger is a sealed metal chamber that transfers heat from burning gas to your home’s air. When that chamber splits, exhaust gases—including carbon monoxide—can enter your air ducts. CO is odorless and deadly even at low levels. In Follansbee’s valley neighborhoods, poor ventilation and damp basements make CO buildup more likely.
Warning signs include:
- Black soot marks around the furnace or vents
- Yellow or flickering burner flames
- Sharp, metallic or chemical-like odors
Carbon monoxide detectors near bedrooms and the furnace provide early protection.
Repair or Replace in Follansbee Homes
Replacing only the heat exchanger involves removing burners, wiring, and flue components—often taking 8–10 labor hours. With labor alone costing around $1,500, a full furnace replacement often makes better financial and safety sense. Modern 90%+ AFUE models lower heating costs and can qualify for energy-efficiency incentives.

FAQs
- Can a cracked heat exchanger be welded or sealed?
- No. Once cracked, it cannot be safely repaired. The only permanent fix is replacing the exchanger or the entire furnace.
- Are Follansbee riverfront homes more prone to furnace corrosion?
- Yes. Moist air from the Ohio River increases internal condensation, which speeds rust in older heat exchangers. Annual service prevents early damage.
