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.
- Applies to: EPA Section 609-certified technician
- Frequency: Any motor-vehicle A/C service for payment
- Scope: This is a DEFERRAL SOP. All recovery, evacuation, and recharge of refrigerant DEFER to EPA Section 609 of the Clean Air Act — performed only by a Section 609-certified tech using EPA-certified equipment. The SOP governs scheduling, eligibility checks, and recordkeeping.
What you need
- EPA Section 609 certification on file
- EPA-certified refrigerant recovery/recharge machine
- OEM A/C service specs
- Refrigerant identifier
- PPE (gloves/eye protection)
- Service record/log
The procedure, step by step
- Verify certification first — Confirm the assigned tech holds current EPA Section 609 certification before the A/C job is dispatched.
- Confirm certified equipment — Verify the recovery/recharge machine is EPA-certified for the refrigerant type in the vehicle.
- Identify the refrigerant — Use a refrigerant identifier to confirm type and check for contamination before connecting equipment.
- Recover before opening — Recover refrigerant with the certified machine before any A/C component is opened — never vent refrigerant to atmosphere.
- Service per OEM — Perform the repair, evacuation, and recharge to OEM A/C specs using ASE-certified judgment.
- Charge to spec — Recharge the exact OEM-specified refrigerant type and amount; verify performance per OEM.
- Keep Section 609 records — Retain on-site records proving each tech using the equipment is Section 609-certified, per EPA.
- Document the job — Record refrigerant type/amount, equipment used, and certification on the invoice/service log.
Quality check before you finish
- Assigned tech’s EPA Section 609 certification verified and on file.
- Recovery/recharge machine confirmed EPA-certified for the refrigerant type.
- Refrigerant identified and checked for contamination before connection.
- Refrigerant recovered — never vented — before any component is opened.
- Recharge matches OEM refrigerant type and amount.
- On-site Section 609 certification records retained per EPA.
- Refrigerant type/amount, equipment, and certification documented.

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.
