A cracked heat exchanger can allow deadly carbon monoxide to leak into household air. In Weirton, exchanger repairs typically cost $1,500–$4,000, while a full furnace replacement averages $2,600–$5,600. Because cracks compromise combustion safety, replacing the entire furnace is usually the safer, longer-term solution for area homeowners.
Weirton’s combination of older steel-mill-era homes, steep hillside neighborhoods like Marland Heights, and damp Harmon Creek basements makes heating equipment work harder. Condensation and rust form easily in the Ohio Valley climate, wearing down furnace metals faster than in drier regions. Many homes downtown and along Main Street still use older venting that can trap exhaust gases. Annual safety inspections help detect small exchanger failures before they release carbon monoxide.
The heat exchanger acts as the sealed barrier between combustion gases and indoor air. When that barrier fractures, carbon monoxide and other exhaust byproducts can pass directly into your vents. In Weirton’s lower-valley homes, humidity and limited basement ventilation can let CO accumulate quickly. Warning signs include yellow or wavering flames, soot around the burner compartment, or metallic odors. A CO detector near the furnace and bedrooms offers critical early warning.
Heat-exchanger replacement involves extensive labor—often eight or more hours of full disassembly. Even under warranty, homeowners still pay for labor and setup, usually close to $1,500. Out-of-warranty repairs may reach $4,000. For Weirton furnaces 10 years or older, replacement is often the better investment. High-efficiency 90% AFUE units lower gas bills in cold valley winters and qualify for local energy rebates.

Watch for soot streaks, metallic odors, or recurring headaches that ease when you leave home. Turn the system off and call a professional immediately.
Yes. Moisture and long heating hours accelerate corrosion, especially in basements near Harmon Creek or below Marland Heights. Regular filter changes and annual cleanings help extend equipment life.
