- 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.

Furnace Repair in Barrington, explained.
Why Furnace Repair Costs Vary in Barrington
Repair costs depend on the component: a simple flame sensor or igniter is more affordable, while a heat exchanger or blower motor is more expensive due to labor and part costs. Older homes (median built 1971) may have outdated systems that require harder-to-find parts or additional labor. Permit fees and the need for a Manual J load calculation on replacements also add to the total. The cold climate means winter emergency repairs can be urgent, potentially increasing after-hours charges.
