- 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.

AC Repair in Oak Park, explained.
Why AC repair costs vary in Oak Park
Repair costs in Oak Park depend on the specific component needing replacement, the age and condition of your system, and whether a permit is required. Older homes (median built 1938) may have outdated wiring or ductwork that increases labor time. Refrigerant type also matters: R-410A is being phased down in 2025, so recharges may cost more if supplies dwindle. Seasonal demand can affect pricing, with summer repairs typically costing more due to higher call volume.
