What Arlington Heights code requires
Installing or replacing an HVAC system in Arlington Heights follows Illinois 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 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.
