The Reality of EPA Enforcement
EPA enforcement actions against HVAC technicians are not hypothetical. The EPA’s Office of Enforcement and Compliance Assurance conducts thousands of inspections annually across the refrigerant management sector. With the addition of Subpart C enforcement for HFC refrigerants in 2026, inspection activity has expanded to cover a larger portion of the refrigerant service industry.
The penalty structure makes non-compliance extremely costly. Maximum penalties for Clean Air Act violations reach $44,539 per day per violation. While actual assessed penalties account for factors like business size and cooperation, even reduced penalties can be catastrophic for a one-person operation. A single audit finding involving multiple service calls generates stacked violations — one per missing or incomplete record.
What Triggers an EPA Audit
Audits can be triggered by several factors, and they may be announced or unannounced:
- Routine inspections. The EPA targets specific sectors in inspection cycles. HVAC service providers are regularly included.
- Tips and complaints. A disgruntled employee, competitor, or concerned customer can file an anonymous tip with the EPA.
- Refrigerant purchase records. Distributors report sales data. Unusually high refrigerant purchases relative to your documented customer base can trigger scrutiny.
- Follow-up inspections. Previous violations or warnings increase the likelihood of re-inspection.
- State agency referrals. State environmental agencies may refer findings to the EPA for federal enforcement.
An unannounced inspection means an EPA inspector arrives at your shop or a customer site and requests records immediately. You will not have time to organize or locate missing documentation.
What Auditors Look For
EPA auditors verify that records are complete, consistent, and contemporaneous — created at or near the time of service, not reconstructed afterward.
1. Technician Certification
You must produce your EPA Section 608 Technician Certification on demand. Keep a digital copy on your phone, a physical copy in your vehicle, and a backup in cloud storage.
2. Service Logs for Every Refrigerant Event
Every instance of adding, recovering, or transferring refrigerant requires a log containing:
- Date of service and technician identification
- Customer name and site address
- Equipment identification (manufacturer, model, serial number)
- Refrigerant type (specific designation, e.g., R-410A)
- Amount added or recovered (in pounds and ounces)
- Full charge of the appliance
- Technician certification number
Auditors flag every omission. Missing any field constitutes an incomplete record.
3. Leak Rate Calculations
For systems above the charge threshold (50 lbs for Section 608, 15 lbs for Subpart C with GWP > 53), auditors verify that a leak rate was calculated every time refrigerant was added, the calculation method is documented, and the rate was compared against the applicable threshold (20% commercial, 15%/10% comfort cooling, 30% industrial).
4. Repair Documentation
When a leak rate exceeds the threshold, the auditor looks for:
- Date the exceedance was identified
- Description of the repair performed
- Date the repair was completed (within 30 days for commercial/comfort cooling, 120 days for industrial)
- Initial verification test results and date
- Follow-up verification test within 30 days of repair
- If repair was delayed, a documented repair extension request or retrofit/retirement plan
5. Refrigerant Disposition Records
When refrigerant is recovered, auditors want to know what happened to it — returned to a reclaimer (with transfer documentation), stored in a tracked cylinder, or recycled on-site. Chain-of-custody documentation is increasingly scrutinized under Subpart C.
Common Audit Findings and Penalties
The most frequent compliance findings for solo HVAC technicians:
| Finding | Consequence |
|---|---|
| Missing service logs | Per-event violation for each undocumented refrigerant handling |
| Incomplete leak rate calculations | Treated as failure to calculate; triggers repair obligation review |
| Missed repair deadlines | Per-day violation from deadline expiration to repair completion |
| No verification test records | Separate violation for failure to verify |
| Records not retained for 3 years | Per-record violation for each prematurely discarded log |
| Illegible or undated records | Treated as incomplete; may be deemed non-contemporaneous |
| No certification on file | Immediate violation; potential referral for uncertified work |
The pattern is clear: documentation failures are the most common source of violations, not the underlying technical work. Many technicians who perform excellent field work expose themselves to enforcement action because their paperwork does not reflect what they actually did.
Organizing Records for Audit Readiness
Your documentation system must allow you to quickly produce records organized by:
- Customer — all service records for a specific client
- Equipment — all service records for a specific piece of equipment, including leak rate history
- Date range — all records within the 3-year retention window
- Refrigerant type — all records involving a specific refrigerant
If an auditor asks for all R-410A service records for the past two years and you cannot produce them within a reasonable timeframe, the audit is already going poorly.
The Digital Advantage
Digital compliance tools address the most common failure points by design:
- Required fields are enforced at entry time, eliminating incomplete records.
- Leak rates are calculated automatically, eliminating arithmetic errors.
- Repair deadlines are tracked with notifications, eliminating missed timelines.
- Records are stored for the full retention period without manual filing.
- Search and export functions produce any subset of records in seconds.
- Timestamped entries demonstrate contemporaneous record creation — something paper cannot inherently prove.
FieldPad’s Audit-Ready Exports
FieldPad was designed with audit readiness as a core requirement:
- Compliance dashboard showing all active equipment, current leak rates, pending repairs, and overdue verification tests at a glance.
- PDF export of individual or bulk compliance logs, filtered by customer, equipment, date range, or refrigerant type.
- CSV export for detailed data analysis in structured format.
- Chronic leaker reports identifying equipment exceeding 125% of the applicable threshold annually, as required by Subpart C.
- Complete audit trail with timestamps showing when each record was created and modified.
All exports generate on-device without an internet connection, so you can produce records immediately during an unannounced inspection at a job site with no cell service.
Key Takeaways
- EPA audits can be unannounced, with fines up to $44,539 per day per violation. Maintain audit-ready records at all times.
- Documentation failures — not technical errors — are the most common violations for solo technicians.
- Every refrigerant event requires a complete service log with date, customer, equipment ID, refrigerant type, amounts, full charge, and technician certification.
- Leak rate calculations must be documented for every refrigerant addition to systems above the applicable charge threshold.
- Repair actions, verification tests, and refrigerant disposition must all be documented with dates and details.
- Records must be retained for 3 years and be producible on demand, organized by customer, equipment, date, or refrigerant type.
- Digital tools like FieldPad eliminate the most common audit findings by enforcing completeness, automating calculations, and generating audit-ready exports on demand.
