Breaking News: EPA Finalized the Reconsidered TT Rule — But Nothing Changes for ALD, Leak Repair, or the Rising Price of HFCs
May 22, 2026
Key Takeaways The EPA's May 21, 2026 reconsidered Technology Transitions Rule relaxed Subpart B GWP installation thresholds — but left Subpart C (ALD and leak repair) completely unchanged. The January 1, 2026 ALD deadline for new equipment and January 1, 2027 deadline for existing 2017–2025 systems remain in full effect. HFC prices are rising due to the phasedown — operators who delay leak repair are now paying more for every pound of refrigerant lost. The common misconception that the TT...

The EPA's Cheat Sheet on Automatic Leak Detection Requirements — Decoded for Facilities Leaders
In January 2026, the EPA published a fact sheet cutting through the complexity of the AIM Act's Automatic Leak Detection requirements — and the deadlines are closer than most facilities leaders realize. If your commercial refrigeration system holds 1,500+ lbs of refrigerant and was installed after January 1, 2017, you have until January 1, 2027 to be fully compliant. Here's exactly what the rule requires, decoded.

JANUARY 1, 2026: WHEN REFRIGERANT LEAKS CAN TRIGGER MANDATORY SYSTEM RETIREMENT
Starting January 1, 2026, the AIM Act’s new rules could force operators to retrofit or retire refrigeration systems that leak persistently—triggering costly replacements if repairs fail.Many businesses mistakenly believe they can delay Automatic Leak Detection (ALD) until 2027, but enforcement begins a year earlier.

THE AUTOMATIC LEAK DETECTION COMPLIANCE PARADOX: WHEN LEAK DETECTION BECOMES A LIABILITY
Under the AIM Act and state-level refrigerant management regulations, Automatic Leak Detection (ALD) systems seem like a convenient “easy button” to help achieve compliance, and they are even required in some cases. But choosing the wrong ALD system, one that floods your inbox with false alarms or fails to detect the right leaks, can backfire in a big way.

THE CHANGING LANDSCAPE OF REFRIGERANT REGULATIONS: WHAT FACILITIES NEED TO KNOW
New York's groundbreaking refrigerant regulations, which took effect January 9th, 2025, signal a significant shift in how facilities must manage their refrigeration systems. The requirements are immediate and substantial: any system using 200+ pounds of refrigerant must undergo quarterly inspections, while 1500+ lb systems require monthly monitoring. All leaks must be repaired within 14 days, and systems that continue to leak fac...

NO NEW HARDWARE: SEAMLESS IMPLEMENTATION OF AXIOM'S EARLY LEAK DETECTION MODULE
For food retailers, managing refrigerant leaks is a critical task, but many detection systems place a heavy burden on operating budgets: the need to install and maintain hardware and monitoring sensors across many facilities. With regulations from the American Innovation and Manufacturing (AIM) Act coming into effect, grocery retailers will be required to install Automatic Lead Detection (ALD) systems. While the EPA lists 10 compliant options presently on the market, not all

COMPLYING WITH EPA HFC RULES: SOFTWARE-BASED LEAK DETECTION FOR GROCERY AND COLD STORAGE
Key Takeaways HFC refrigerants, when leaked, become potent greenhouse gases — compliance with EPA phasedown rules requires active monitoring, not passive management. Traditional sensor-based leak detection is complex, expensive, and requires ongoing hardware maintenance across multi-site fleets. Software-based detection leverages data already flowing from existing refrigeration controllers — no new infrastructure required. Grocery and cold storage operators can achieve full A

NAVIGATING THE EPA’s NEW HFC REGULATIONS: WHAT COMMERCIAL REFRIGERATIONS OWNERS NEED TO KNOW
Key Takeaways The EPA's HFC phasedown under the AIM Act introduces new mandatory monitoring, leak repair timelines, and reporting requirements for commercial refrigeration owners. Non-compliance carries per-day, per-violation fines that can escalate rapidly for operators managing large refrigerant fleets. Understanding which systems are covered, what leak rates trigger action, and how to document compliance is essential for facility managers. Axiom Cloud simplifies this compl
