Furnace repair cost by part.
Typical University City repair pricing including parts and labor. A diagnostic fee usually applies and is often credited toward the work.
Furnace repair costs in University City, Missouri, typically range from $75 for a simple flame sensor replacement to over $3,200 for a heat exchanger. With a median home age of 75 years, many homes have aging furnaces that require frequent repairs. Local labor rates and the need for a mechanical permit (required by University City) add to the cost. Most homes use gas furnaces, and the mixed-humid climate means moderate cooling demand, making an AC-gas furnace system a common choice. The federal 25C tax credit can offset costs for qualifying high-efficiency equipment.
