Furnace repair cost by part.
Typical Downers Grove repair pricing including parts and labor. A diagnostic fee usually applies and is often credited toward the work.
In Downers Grove, where the median home was built in 1973, furnace repair is a common need for aging systems. Typical costs range from a $75–$200 diagnostic fee to $80–$250 for a flame sensor, $150–$450 for an igniter, $400–$1,500 for a blower motor, $300–$800 for a control board, and $1,500–$3,500+ for a heat exchanger.

What Downers Grove code requires

- 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 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—
Illinois follows the 2021 IECC, which requires an ACCA Manual J load calculation for HVAC sizing on permitted installs; cold-climate winter sizing matters in the north.
