A/C Refrigerant Work — EPA Section 609 (Deferral SOP): the full procedure

Govern the workflow and recordkeeping around motor-vehicle A/C jobs while deferring all refrigerant handling to a Section 609-certified tech with certified equipment.

What you need

The procedure, step by step

  1. Verify certification first — Confirm the assigned tech holds current EPA Section 609 certification before the A/C job is dispatched.
  2. Confirm certified equipment — Verify the recovery/recharge machine is EPA-certified for the refrigerant type in the vehicle.
  3. Identify the refrigerant — Use a refrigerant identifier to confirm type and check for contamination before connecting equipment.
  4. Recover before opening — Recover refrigerant with the certified machine before any A/C component is opened — never vent refrigerant to atmosphere.
  5. Service per OEM — Perform the repair, evacuation, and recharge to OEM A/C specs using ASE-certified judgment.
  6. Charge to spec — Recharge the exact OEM-specified refrigerant type and amount; verify performance per OEM.
  7. Keep Section 609 records — Retain on-site records proving each tech using the equipment is Section 609-certified, per EPA.
  8. Document the job — Record refrigerant type/amount, equipment used, and certification on the invoice/service log.

Quality check before you finish

This is a free, source-anchored standard operating procedure (SOP) you can print and hand to staff. It documents the work sequence for a Mobile Mechanic business — not safety or regulatory rulings, which defer to the cited authorities, the applicable code, and your own health-and-safety plan. Open the tool above to print it, toggle ink-saver, or (with a free ToolFluency Business account) edit it to match your own workflow.

Frequently asked questions

Who is allowed to service vehicle A/C under this SOP?
Only a technician certified under EPA Section 609 of the Clean Air Act, using EPA-certified recovery/recharge equipment. Section 609 applies to servicing any MVAC system for payment regardless of the refrigerant used — this is a hard legal requirement, not an internal policy.
Can refrigerant ever be vented to the air?
No. It must be recovered with certified equipment before any A/C component is opened. The shop must also keep on-site records proving each person using the equipment is Section 609-certified — refrigerant handling defers entirely to EPA Section 609 and the certified tech.
