New EPA Refrigerant Rules Are Now in Effect — What Chicago Business Owners Need to Know

If your commercial building in the Chicago area runs on R-410A or older refrigerants, federal law changed on January 1, 2026 — and your facility’s compliance clock is already ticking.

The EPA’s AIM Act (American Innovation and Manufacturing Act) is now in its most aggressive enforcement phase yet. For facility managers, property owners, and operations directors across Chicagoland, this is not a distant regulatory concern — it is an active legal obligation that affects your equipment, your service contracts, your capital planning, and potentially your bottom line.

Background: What Is the AIM Act?

Signed into federal law in 2020, the AIM Act gave the EPA broad authority to phase down the production and use of hydrofluorocarbons (HFCs). The AIM Act’s phase-down schedule is aggressive — targeting an 85% reduction in HFC production and consumption over the next 15 years. The first major milestone for commercial business owners hit on January 1, 2026.

The R-410A Phase-Out: What It Means for Your Building

As of January 1, 2026, the EPA has banned the manufacture and import of new HVAC equipment that uses R-410A. While existing systems can still legally operate, the market is already shifting fast: R-410A refrigerant prices are rising, new replacement equipment uses next-generation refrigerants like R-454B or R-32, and not all contractors are equipped to service them.

New Leak Detection and Reporting Requirements

• Routine leak inspections at EPA-mandated intervals
• Prompt leak repairs within 30–120 days depending on category
• Refrigerant tracking logs retained for a minimum of three years
• EPA reporting for facilities exceeding annual leak rate thresholds
