A cracked heat exchanger is one of the most serious furnace failures a homeowner can face. In Wintersville, repairs average $1,500–$4,000, while a full furnace replacement ranges $2,600–$5,600. Because a crack can leak carbon monoxide, most professionals recommend replacing the furnace entirely for safety and long-term reliability.
Wintersville’s mix of 1960s ranch homes, newer Fernwood Road developments, and older hillside basements makes furnace safety a real concern. Cold Jefferson County winters, combined with tightly sealed homes, increase the risk of carbon monoxide buildup. Many houses near John Stephenson Highway or Hooverson Heights still rely on older gas venting and compact basements with limited airflow. Regular inspections help prevent serious safety issues before heating season peaks.
The heat exchanger forms the metal wall between combustion gases and the air circulating through your vents. When cracks form, exhaust can mix with breathable air. That leak can release carbon monoxide, an odorless gas that displaces oxygen in your bloodstream. In Wintersville’s lower-level basements or homes near wooded lots, CO can accumulate unnoticed. Warning signs include yellow flames, soot around the burner area, or a metallic smell. CO detectors near bedrooms and the furnace should be tested monthly.
Replacing the exchanger alone often requires full furnace disassembly, taking eight or more labor hours. Under warranty, that repair can cost $1,500; out of warranty, up to $4,000. Because most local systems are over a decade old, a full furnace replacement is usually the better value. New 90%+ AFUE models lower gas bills and qualify for energy-efficiency credits through AEP Ohio.

No. Even a small crack compromises combustion safety. A licensed technician should confirm the diagnosis and review full replacement options.
Yes. Many older basements lack proper ventilation, allowing exhaust gases to linger. Installing CO detectors and maintaining airflow greatly reduce that risk.
