40 CFR §84.106 · effective January 1, 2026

The refrigerant paperwork is now the law's problem for your shop.

On January 1, 2026 the AIM Act's 15-lb rule pulled hundreds of thousands of ordinary commercial systems — restaurants, groceries, cold storage — into federal leak-tracking, repair clocks, and recordkeeping. LeakClock does it for you: scan the tag, weigh the cylinder, done. The math, the 30-day clock, and the EPA audit binder happen automatically.

Why this is suddenly your problem

The threshold dropped from 50 lbs to 15. The fines did not get smaller.

For decades, leak-repair rules only touched big 50-lb+ systems. The 2026 rule (40 CFR §84.106) applies the same math, clocks, and records to any appliance with 15 pounds or more of an HFC refrigerant with GWP over 53 — the reach-in racks, rooftop units, and walk-ins in nearly every commercial building. Most of their owners have no recordkeeping system at all.

15 lb
New threshold — down from 50 lb. §84.106(a)

$124k
Max civil penalty per day, per violation. 40 CFR §19.4

Every record must be kept. §84.106(l)

Penalty figure: Clean Air Act §113(b) judicial maximum as inflation-adjusted in 40 CFR §19.4, table 1 (assessed on/after Jan 8, 2025). Administrative penalties are separate. Verify the current-year figure before relying on it.

In the field — under 90 seconds per service

Scan the tag. Weigh the cylinder. Done.

The person creating the record is a tech on a rooftop with gloves on and often no signal. So the field app is five taps, works fully offline, and never asks them to know a regulation — the engine does the compliance thinking.

Scan

Point the camera at the appliance's QR tag. Unknown tag? Snap the nameplate and the app reads it.

Confirm

The appliance card shows charge, refrigerant, category, and history — verify it's the right unit.

Weigh

Enter cylinder-before / cylinder-after. The app computes pounds added, catches swapped weights.

Verdict

Instant leak rate with the exact arithmetic and CFR citation — over or under the trigger, in plain terms.

Register

New appliance? Nameplate photo → a full record and a printable QR tag, all on-device.

Every tap writes to an append-only, tamper-evident log that is the offline queue. When signal returns, a full day of work merges cleanly into the office view — no lost records, no double entries.

In the office — the part the EPA asks to see

One dashboard. Every deadline. The binder on a button.

Appliance registry

Every unit across every site, its current leak rate, and whether a compliance case is open — synced from the field automatically.

Deadline clocks

The 30-day repair window, 10-day follow-up, quarterly/annual inspections, chronic-leaker reports — counted down for you, colour-coded, nothing forgotten.

Audit binder & owner reports

Generate the EPA audit pack and per-owner reports as PDFs, each footer stamped with the record chain's hash — tamper-evident by construction.

Print QR tag sheets, manage billing, hand equipment owners a branded compliance report — and every one of those reports quietly recruits the next shop.
