Furnace repair cost by part.
Typical Lebanon repair pricing including parts and labor. A diagnostic fee usually applies and is often credited toward the work.
Furnace repair costs in Lebanon, Missouri, typically range from a $55–$150 diagnostic fee to several hundred or thousand dollars for parts and labor. With a median home age of 46 years, many systems are older and may need common repairs like flame sensor or blower motor replacement. Lebanon is in a mixed-humid climate with moderate cooling demand, and most homes use gas heating. Missouri has no statewide mechanical code, so permit and inspection requirements are set locally—check with the city of Lebanon before work begins. For a typical repair, expect to pay $60–$200 for a flame sensor, $125–$350 for an igniter, $300–$1,150 for a blower motor, $225–$600 for a control board, or $1,150–$2,700+ for a heat exchanger. The federal 25C tax credit (30%, up to $2,000 for a qualifying heat pump or $600 for a high-efficiency AC) is available in Missouri, but it applies to new equipment, not repairs.

What Lebanon code requires
Installing or replacing an HVAC system in Lebanon follows Missouri rules under the state mechanical code. Here’s what applies statewide:
- PermitRequired
Mechanical permit pulled by your licensed HVAC contractor; covers equipment, refrigerant, and the electrical disconnect.
- SEER2 minimum13.4 SEER2 (North)
Federal North-region minimum for new split-system AC. Higher tiers cut bills and unlock rebates.
- Load calculationRecommended
Sizing by load calc — not rule of thumb — prevents an oversized unit that short-cycles and never dehumidifies.
- RefrigerantR-454B / R-32 (R-410A phased down 2025+)
- Good to know—
Missouri has no statewide residential building/mechanical code, so permit and inspection requirements are set locally by each city or county.

Furnace Repair in Lebanon, explained.
What affects furnace repair costs in Lebanon?
Prices vary based on the part needed, labor rates, and whether a permit is required. Lebanon's median household income is $45,634, and homeownership is 47.2%, so local labor rates are generally lower than in major metros. Older homes (median built 1980) may have harder-to-find parts or require more labor. The lack of a statewide code means some repairs may not need a permit, but if the city requires one, that adds to the cost. The type of system (gas furnace vs. heat pump) also affects repair complexity and cost.
Common furnace repairs in Lebanon
Flame sensor failure
A dirty or faulty flame sensor is a frequent issue in older furnaces, causing the system to shut off after ignition. Repair cost: $60–$200.
Igniter problems
The igniter can crack or wear out over time, preventing the furnace from starting. Replacement runs $125–$350.
Blower motor malfunction
A failing blower motor reduces airflow and heating efficiency. Replacement costs $300–$1,150.
