The Environmental Protection Agency's Emissions Reduction and Reclamation rule under the American Innovation and Manufacturing Act took effect January 1, 2026, lowering the mandatory refrigerant leak repair threshold from 50 pounds — the long-standing Section 608 limit — to 15 pounds for appliances containing HFC refrigerants or certain HFC substitutes with a global warming potential above 53. The change expands federal regulatory oversight to an estimated millions of additional commercial HVAC and refrigeration systems that had previously fallen below the compliance threshold, fundamentally reshaping refrigerant management obligations for building owners, facility managers, and the contractors who service their equipment.
Under the old Section 608 framework, only comfort cooling and refrigeration systems with 50 or more pounds of refrigerant were subject to mandatory leak rate calculations, repair timelines, and retrofit or retirement planning. The ER&R rule drops that threshold to 15 pounds — capturing a large category of smaller rooftop units, commercial refrigeration cases, split systems in medical offices, retail spaces, educational facilities, and other commercial buildings that had previously operated outside the regulated leak management framework. The first time refrigerant is added to a covered system on or after January 1, 2026, a leak rate calculation must be performed. If that calculation reveals a leak rate above the applicable subsector threshold, a 30-day mandatory repair clock begins.
The Repair, Retrofit, and Retire Sequence
The ER&R rule's repair-or-retire mechanism is the provision that creates the most immediate financial exposure for system owners. If a covered system is found to be leaking above the applicable threshold rate — 10% for comfort cooling; 20% for commercial refrigeration — the owner has 30 days to repair the leak and perform verification tests confirming that the leak rate has dropped below the threshold. If the repair succeeds, the system returns to normal compliance monitoring. If the 30-day repair fails to bring the system into compliance, the owner must develop a retrofit or retirement plan and complete the retrofit or retirement of the system within one year.
For systems with older compressors, condensers, or refrigeration circuits that are prone to persistent leaking, the retrofit-or-retire obligation can trigger a mandatory system replacement on a much shorter timeline than the owner would have chosen independently. The practical implication for facilities management teams is that systems containing 15 to 49 pounds of refrigerant — units that were previously entirely outside the federal leak management framework — must now be included in compliance tracking programs, serviced by EPA Section 608-certified technicians, and maintained under the same documentation and record-keeping standards as larger systems.
Automatic Leak Detection Requirements
For the largest systems, the ER&R rule goes further. Industrial process refrigeration and commercial refrigeration appliances with a full charge of 1,500 pounds or more of HFC refrigerant must be equipped with automatic leak detection systems — direct or indirect — that meet EPA performance criteria including minimum detection thresholds. New appliances installed in 2026 must include ALD at installation or within 30 days. Existing appliances installed between January 1, 2017, and January 1, 2026, have until January 1, 2027, to comply with the ALD requirement. EPA estimates leak repair and ALD requirements combined will save approximately $19.5 million in 2026 through reduced need to replace leaked refrigerant, and will prevent approximately 5.6 million metric tons of CO₂-equivalent HFC emissions by 2030 — roughly equivalent to removing more than one million cars from the road.
Reclamation Requirements
Alongside the leak repair provisions, the ER&R rule establishes the first national reclamation standard for HFC refrigerants. As of January 1, 2026, reclaimed HFC refrigerants may contain no more than 15% virgin HFCs by weight. Containers of reclaimed refrigerant must be labeled to certify the virgin HFC content limit is not exceeded, and reclaimers must maintain records for three years. Additionally, beginning January 1, 2029, reclaimed HFC refrigerants must be used to service equipment in the supermarket, refrigerated transport, and automatic commercial ice maker subsectors — a provision that will structurally increase demand for reclaimed refrigerant in exactly the commercial applications that Kroger and other major grocers are now committed to managing under DOJ consent decrees.
What Contractors Need to Do Now
For HVAC contractors whose commercial accounts include systems in the 15-to-49-pound charge range, the immediate action items are clear: confirm total system charge for all commercial accounts; update service contracts to include leak rate calculations at each refrigerant addition; ensure technician Section 608 certification is current; and implement record-keeping documentation for refrigerant additions, recoveries, and leak rate calculations that satisfies EPA audit requirements. EPA penalties under the Clean Air Act can reach $60,000 per violation per day — a consequence that underscores the importance of building compliant documentation practices now rather than waiting for an enforcement action.
