Frequently Asked Questions

EPA Section 608 of the Clean Air Act regulates the handling, recovery, recycling, and reclamation of refrigerants used in air conditioning and refrigeration equipment. It applies to any business or individual that handles refrigerants commercially — including HVAC contractors, property managers, facility managers, and any employer whose employees service refrigeration equipment.

Key requirements include: technician certification, refrigerant purchase and use logs, appliance service records, leak inspection and repair protocols, proper recovery before servicing or scrapping equipment, and a prohibition on intentional venting of refrigerant.

40 CFR Part 82, Subpart F

The three most commonly cited record types are:

1. Refrigerant purchase and use logs — every purchase must be logged with the type, quantity, date, supplier, and equipment it was applied to. Retention: 3 years. 40 CFR §82.166(a)

2. Appliance service records — for every system with 50+ lbs of refrigerant (15+ lbs under AIM Act 2026 for HFCs), each service visit requires a record including date, technician, refrigerant type and amount added/removed, and reason for service. Retention: 3 years. 40 CFR §82.166(b)(2)

3. Technician certification records — EPA 608 certificates for every technician who handles refrigerant. These must be produced on inspection. 40 CFR §82.161

Additional records required in specific circumstances: leak inspection reports, repair completion documentation, refrigerant recovery equipment certification, and disposal/scrapping records.

Both. HVAC contractors are responsible for their technicians' certifications, service records, and refrigerant purchase logs. But property managers and building owners face a separate layer of exposure.

Under Section 608, if refrigerant is improperly handled on your property — even by a contractor you hired — enforcement action can fall on the owner of record, not just the contractor. This is especially relevant for large systems with chronic leaks that haven't been properly reported or repaired.

A written compliance audit gives property managers documented evidence that due diligence was exercised, which is meaningful protection in an enforcement context.

Leak thresholds trigger inspection and repair obligations. Under Section 608:

• Comfort cooling (HVAC): 10% of charge per year triggers a 30-day repair window

• Commercial refrigeration: 20% of charge per year — with a 14-day repair window under AIM Act 2026

• Industrial process refrigeration: 30% of charge per year

If a system leaks 125%+ of its charge in a single 12-month period, it is classified as a "chronic leaker" and must be reported to the EPA. 40 CFR §82.157

Under the AIM Act, thresholds now apply to systems with 15+ lbs of HFC refrigerant, not just the older 50 lb ODS threshold.

The AIM Act Subpart C regulations took effect January 1, 2026 and made several significant changes:

Lower threshold: The compliance threshold dropped from 50 lbs of ozone-depleting substances (ODS) to 15 lbs of any HFC refrigerant with a GWP above 53. This brings millions of additional systems — standard rooftop units, server room A/C, small commercial refrigeration — under federal regulation for the first time.

Reclaimed refrigerant requirement: Service of existing HFC equipment must now use reclaimed refrigerant. Up to 5% virgin refrigerant is permitted, but the default requirement is reclaimed product.

Faster repair windows: Commercial refrigeration facilities now have 14 days (not 30) to complete leak repairs.

System registration: Large facilities (1,500+ lbs) had to register by March 15, 2024. Medium facilities (200–1,499 lbs) must register by March 15, 2026. Small facilities (50–199 lbs) by March 15, 2028.

It depends on the size of your systems. AIM Act Subpart C requires registration for facilities with HFC systems above certain thresholds:

• Large facilities (1,500+ lbs HFC): Registration deadline was March 15, 2024. Annual reporting required one year after registration.

• Medium facilities (200–1,499 lbs HFC): Registration deadline is March 15, 2026. Annual reporting required one year after registration.

• Small facilities (50–199 lbs HFC): Registration deadline is March 15, 2028.

If you manage multiple buildings, each location is assessed separately. Veriflo Compliance can help identify which of your facilities trigger registration and assist with the filing process.

R-410A in new equipment: Banned from manufacture after January 1, 2025. Existing R-410A equipment has no mandatory retrofit requirement — you can continue to service it indefinitely with reclaimed R-410A.

R-454B and R-32: These are the primary replacements for new equipment manufacture. Both are classified as A2L refrigerants (mildly flammable) and require specific handling considerations. R-454B has a GWP of 466 (vs. R-410A's 2,088). R-32 has a GWP of 675.

A2L safety note: Leak detection sensors are required in occupied spaces where R-454B charge exceeds 3.91 lbs, and where R-32 charge exceeds the applicable threshold. This is a new compliance area that many contractors are not yet aware of.

Veriflo Compliance can assess your A2L refrigerant exposure as part of a Starter Audit or as a standalone add-on service.

The maximum civil penalty is $44,539 per violation per day. That figure is adjusted periodically for inflation under the Federal Civil Penalties Inflation Adjustment Act.

In practice, EPA enforcement typically issues Notices of Violation (NOVs) before seeking penalties, and the final penalty amount depends on factors including: the severity of the violation, the economic benefit to the violator, the violator's compliance history, and good-faith remediation efforts.

Common penalty ranges for first-time violations:

• Missing or incomplete refrigerant purchase logs: $5,000–$25,000

• Uncertified technicians: $10,000–$30,000 per technician

• Unreported chronic leaker: $15,000–$50,000+

• Intentional venting: $44,539/day for every day of noncompliance

Self-disclosure of violations before an inspection significantly reduces penalty exposure. The EPA's Audit Policy provides formal penalty mitigation for self-identified violations.

EPA Section 608 inspections are initiated through several channels:

• Routine inspections: EPA Region offices and state environmental agencies conduct periodic compliance inspections of HVAC contractors and large facilities.

• Tip-based referrals: Complaints from employees, competitors, neighbors, or customers who observe improper refrigerant handling.

• Supplier audit trails: Refrigerant distributors are required to maintain sales records and verify buyer certification. Anomalies (large purchases without documentation) can trigger review.

• Other enforcement crossover: If a business is inspected for an unrelated environmental violation, inspectors may review refrigerant compliance as part of a broader audit.

Inspectors do not announce themselves in advance for routine inspections. They can request records on-site and will note deficiencies immediately.

A Notice of Violation (NOV) is not a fine — it is a formal notification that the EPA has identified a specific regulatory violation. You typically have 30 days to respond in writing.

The response letter is critical. It should: acknowledge receipt, identify each alleged violation, describe corrective actions already taken, provide a timeline for remaining corrections, and present any mitigating factors.

A well-structured response demonstrating good-faith remediation can significantly reduce the proposed penalty or avoid it entirely. A weak or absent response accelerates the penalty assessment process.

Veriflo Compliance can draft violation response letters as a standalone service for any tier. Contact us immediately if you've received an NOV — time is a factor.

The process is straightforward:

1. Book a free discovery call (15 minutes). We discuss your business and confirm the audit is the right fit.

2. Receive and complete the intake form. An 8-section questionnaire covering your equipment inventory, technician roster, current recordkeeping setup, and any known issues. Most clients complete it in 20–30 minutes.

3. Upload documents. We provide a shared folder link. You upload what you have — purchase logs, service records, tech certifications, prior inspection reports. If you have nothing, that tells us something too.

4. We conduct the audit. We review everything against current 40 CFR Part 82 and AIM Act requirements.

5. You receive the report. A formatted PDF compliance report delivered within 48 hours of intake completion. Color-coded findings, CFR citations, and a prioritized action checklist.

Yes. EPA Section 608 is federal law — the same requirements apply to HVAC contractors and property managers in every state. Veriflo Compliance operates entirely remotely. Intake forms, document uploads, reports, and client communication are all handled digitally.

Note that some states have additional refrigerant regulations on top of federal Section 608 requirements (California in particular, under CARB). For California clients, we address CARB compliance separately. Ask about your state on the discovery call.

Yes — and this is actually one of the most valuable situations to audit. Starting from zero means the audit will identify everything that needs to be created, in priority order, with specific templates and formats that satisfy EPA requirements.

We can also provide refrigerant log reconstruction as an add-on service — working backward through supplier invoices, service tickets, and equipment records to build a defensible historical log. This is often necessary for businesses that have never maintained formal purchase records but have years of purchase history with their refrigerant supplier.

Software tools like RefriTrak, FMHero, or SafetyCulture are record-tracking tools. They help you maintain logs. They do not:

• Tell you which records are legally required vs. optional

• Flag when a log format won't satisfy an inspector

• Identify when a leak threshold has been crossed and what the reporting obligation is

• Produce a written compliance report

• Draft a response to a Notice of Violation

• Alert you when regulations change and explain what the change means for your business

Software tracks. Veriflo Compliance interprets. The combination of both is ideal — use a tracking tool for day-to-day record maintenance, and Veriflo Compliance to audit those records and manage regulatory compliance.
