Furnace repair cost by part.
Typical Farragut repair pricing including parts and labor. A diagnostic fee usually applies and is often credited toward the work.
Furnace repair in Farragut, Tennessee, typically runs $70–$175 for a diagnostic fee, with common repairs like flame sensor replacement costing $75–$225 and igniter replacement $150–$425. Most homes were built around 1992, so furnaces are often 30+ years old and may need more extensive repairs such as blower motor ($375–$1,400) or heat exchanger ($1,400–$3,300+). Tennessee requires a mechanical permit for furnace work, and load calculations are recommended to ensure proper sizing. Given that Farragut's primary heating is electric and the climate is mixed-humid, a heat pump is often a well-suited choice for both heating and cooling, and federal 25C tax credits (up to $2,000 for qualifying heat pumps) may apply.

Furnace Repair in Farragut, explained.
What affects furnace repair costs in Farragut?
Repair costs in Farragut depend on the part needed and labor time. For example, a simple flame sensor fix is more affordable than a blower motor or heat exchanger replacement. The age of your furnace (median home built 1992) may mean parts are harder to find. Permit fees and the need for load calculations can add to the total. If you choose a heat pump instead of repairing an old furnace, federal tax credits may offset some cost, but TVA EnergyRight rebates typically require electric primary heat and a Quality Contractor Network member.
