Furnace repair cost by part.
Typical Maryville repair pricing including parts and labor. A diagnostic fee usually applies and is often credited toward the work.
Furnace repair costs in Maryville, Tennessee, typically range from $75 for a simple flame sensor replacement to over $3,300 for a heat exchanger. With a median home age of 41 years, many furnaces are nearing or past their expected lifespan. Tennessee requires a mechanical permit for furnace repairs, and load calculations are recommended for proper sizing. Most homes use electric heating, so a heat pump is often a strong fit for both heating and cooling. The federal 25C tax credit offers up to $2,000 for qualifying heat pumps, but TVA EnergyRight rebates require electric primary heat and a Quality Contractor Network member.

Furnace Repair in Maryville, explained.
What Affects Furnace Repair Costs in Maryville
Labor rates in Maryville reflect a smaller market, with diagnostic fees of $70–$200. The age of your furnace (median 41 years) often means older parts are harder to find, increasing costs. The type of repair matters: a flame sensor is more affordable ($75–$225), while a blower motor ($375–$1,400) or control board ($275–$750) costs more. Heat exchanger repairs are the most expensive ($1,400–$3,300+) and may require a permit. Choosing a heat pump can qualify for federal tax credits, but installation must meet SEER2 minimums (14.3 SEER2 for Southeast).
