Typical Madisonville repair pricing including parts and labor. A diagnostic fee usually applies and is often credited toward the work.
Furnace repair in Madisonville, Kentucky, typically costs between $65 and $2,800 depending on the component. With a median home age of 52 years, older furnaces often need repairs like flame sensor or igniter replacements.

What Madisonville code requires
Installing or replacing an HVAC system in Madisonville follows Kentucky 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 minimum14.3 SEER2 (Southeast, <45k BTU)
Federal Southeast-region minimum for new split-system AC. Higher tiers cut bills and unlock rebates.
- Load calculationRequired (Manual J)
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—
Kentucky runs a statewide HVAC licensing, permitting and inspection program (first in the US); a permit plus final inspection is required for every install/replacement, and proof of adequate sizing is required on the permit application.
