Furnace repair cost by part.
Typical Trenton repair pricing including parts and labor. A diagnostic fee usually applies and is often credited toward the work.
Furnace repair costs in Trenton, Ohio, typically range from $70 for a diagnostic fee to over $3,200 for a heat exchanger replacement. With a median home age of 34 years, many furnaces are nearing or past their expected lifespan, making repairs common. Trenton's mixed-humid climate and reliance on gas heating mean that flame sensors, igniters, and blower motors are frequent repair items. Local repairs must comply with the Residential Code of Ohio and Ohio Mechanical Code, and a mechanical permit is required for most work, though requirements vary by jurisdiction. The federal 25C tax credit offers up to $600 for high-efficiency central AC, but does not apply to furnace repairs.
