Furnace repair cost by part.
Typical Gallatin repair pricing including parts and labor. A diagnostic fee usually applies and is often credited toward the work.
Furnace repair costs in Gallatin, Tennessee, typically range from $75 for a simple flame sensor replacement to over $3,200 for a heat exchanger, plus a $70–$175 diagnostic fee. With a median home age of about 25 years, many furnaces are due for service. Tennessee requires a mechanical permit for furnace repairs, and load calculations are recommended for proper sizing. Given the mixed-humid climate and mostly electric heating, a heat pump is often a strong fit for replacements, especially with federal 25C tax credits available (30% up to $2,000 for qualifying heat pumps).
