Every commercial HVAC operator who handles refrigerant is now closer to a federal audit than they were a year ago. As of January 1, 2026, the threshold that pulls equipment into full leak-management scope dropped from 50 pounds to 15 pounds for systems charged with high-GWP HFCs. For most portfolios, that single change converts a pile of previously exempt rooftop units, splits, and process equipment into tracked assets — and it raises the stakes on EPA 608 compliance for the whole operation.
The consequence lands fast. A unit you topped off twice last summer without a second thought may now sit above a leak-rate trigger, with a 30-day repair clock and a documentation trail you are expected to produce on demand. Operators who treated refrigerant logs as an afterthought are discovering that “we serviced it” is not the same as “we can prove what we did, when, and to which asset.”
What EPA 608 compliance actually requires
Section 608 of the Clean Air Act governs the handling of refrigerants in stationary equipment. The core obligations have been stable for years: technicians servicing covered equipment must hold EPA 608 certification, intentional venting is prohibited, and only certified recovery equipment may be used. In addition, owners and operators of appliances containing 50 or more pounds of refrigerant must keep servicing records, and those records must be available for EPA inspection — which in practice means retrievable now, not after a weekend of searching trucks and text threads.
Historically, the leak-repair provisions applied to ozone-depleting refrigerants such as R-22. When a covered system exceeds its leak-rate threshold, the leak must be repaired within 30 days, and if it cannot be, the operator must put a retrofit or retirement plan in place. Those thresholds still stand for ozone-depleting systems, as shown below.
| Equipment category | Leak-rate threshold (annual) |
|---|---|
| Industrial process refrigeration | 30% |
| Commercial refrigeration | 20% |
| Comfort cooling | 10% |
What changed in 2026 and why EPA 608 compliance now reaches further
The expansion comes from the AIM Act rather than Section 608 itself. Under the HFC management rule finalized in late 2024 and effective January 1, 2026, leak-repair and management requirements now extend to appliances containing 15 or more pounds of HFCs (and substitutes) with a global warming potential above 53 — a group that includes R-410A, R-404A, and R-134a. For the first time, equipment in the 15-to-49-pound range carries leak-rate calculation, 30-day repair, and retrofit-or-retirement obligations that previously applied only to much larger systems.
To make that concrete, picture a light-commercial split charged with roughly 20 pounds of R-410A. A year ago it sat comfortably below the 50-pound line and carried no leak-rate obligation whatsoever; today it falls squarely inside the 15-pound HFC scope, which means a documented leak-rate calculation on every refrigerant addition and a 30-day repair clock once it crosses the threshold. Multiply that single reclassification across a portfolio of rooftop units and splits, and the administrative load becomes real rather than theoretical.
There is also an automatic leak detection requirement, but it is narrower than the headlines suggest. It applies to industrial process and commercial refrigeration systems holding 1,500 pounds or more — new installations from January 1, 2026, and qualifying existing systems by January 1, 2027. Comfort cooling is generally outside that automatic-detection scope. The table below contrasts the two regimes operators now juggle.
| Factor | Section 608 (ozone-depleting) | AIM Act HFC rule (effective 2026) |
|---|---|---|
| Refrigerants | R-22 and other ODS | HFCs / substitutes, GWP > 53 (R-410A, R-404A, R-134a) |
| Charge threshold | 50+ lbs | 15+ lbs |
| Repair window | 30 days, then retrofit/retire plan | 30 days, then retrofit/retire plan |
| Records retention | 3 years, inspectable | 3 years, inspectable |
One forward-looking caveat belongs here, framed as exactly that. The companion Technology Transitions Rule, which caps the GWP of refrigerant used in new equipment and has pushed new air-conditioning gear toward R-454B and R-32, was reopened for reconsideration in late 2025. Our read is that the direction of travel — lower-GWP refrigerants and tighter leak accountability — is unlikely to reverse, but specific effective dates and limits could shift. Treat that piece as live policy to watch, not settled fact, and verify current applicability for your equipment.
The records that keep you audit-ready
Strong operators do not chase compliance after the fact; they capture it during the round. At minimum, your refrigerant records should let you reconstruct the history of any covered asset on demand.
- Asset register: every covered unit with refrigerant type, full charge, and a stable asset ID.
- Service events: date, technician, refrigerant added or recovered, and the quantity, tied to the asset.
- Leak-rate calculation: recalculated on each addition to a covered system, using one documented method applied consistently.
- Repair and verification: what was repaired, the verification test, and the date — or the retrofit/retirement plan if the 30-day window is missed.
- Certifications: current technician 608 certifications on file.
Here is the field reality that trips operators up. A technician adds two pounds to a chronically weeping condenser on a hot Friday, logs nothing, and moves to the next call. Repeat that across a season and the asset has quietly blown past its leak-rate trigger with no calculation, no repair record, and no plan — the textbook profile of a violation if an inspector ever asks. The refrigerant was cheap. The exposure is not.

Operator takeaway
The smartest move this quarter is unglamorous: inventory every system against the new 15-pound HFC threshold and find out which assets just entered scope. From there, standardize how leak rates are calculated and make refrigerant logging a non-negotiable step of the round rather than a memory exercise. Penalties for noncompliance run to tens of thousands of dollars per day, but the more common cost is quieter — a lost contract when a building owner asks for a refrigerant history you cannot produce.
Get the asset register and the logging discipline right, and the rest of EPA 608 compliance becomes routine. For the official requirements, consult the EPA Section 608 program, and for more HVAC compliance coverage, see our HVAC maintenance resources.
