Refrigerant Recovery for Light Commercial Equipment
EPA-compliant refrigerant recovery from light commercial equipment including required vacuum levels, recovery machine operation, cylinder management, and documentation requirements.
- Perform EPA-compliant refrigerant recovery from light commercial systems to required levels
- Operate recovery machines and manage recovery cylinders safely
- Determine correct recovery requirements based on equipment type and charge size
- Document refrigerant recovery and disposal per EPA Section 608 regulations
Lesson 1
EPA Recovery Requirements for Light Commercial Equipment
Section 608 Recovery Mandates
Before opening any refrigerant system for repair, the technician must recover refrigerant to EPA-required levels. The specific requirement depends on the type of equipment and whether the recovery machine was manufactured before or after November 15, 1993.
Most light commercial equipment uses high-pressure refrigerants (R-134a, R-404A, R-290) and requires recovery to 0 psig before the system can be opened. For systems with known leaks that make holding 0 psig impossible, recover to the maximum extent achievable.
When Recovery Is Required
Recovery is required before:
- Opening any part of the refrigerant circuit for repair (compressor replacement, TXV service, cap tube replacement)
- Disposing of any appliance containing refrigerant (scrap, decommission)
- Making any repair that requires cutting into refrigerant-containing piping
Recovery is not required for:
- Self-contained equipment with less than 200 grams of refrigerant that has been pressure-tested and verified to be free of contaminants (certain small appliances)
- Systems that have already lost their entire charge through leaks (no refrigerant remaining to recover)
Venting Is Illegal
Knowingly venting any regulated refrigerant (R-134a, R-404A, R-407C, R-410A, and HFC blends) is a federal violation under Section 608. The EPA can impose fines up to $69,733 per day per violation (2026 inflation-adjusted); subsequent violations can reach $209,202 to $214,637. Even small releases during hose disconnection (de minimis releases) should be minimized. The only substances that can be legally vented are CO2, nitrogen, water, ammonia, and hydrocarbons - though hydrocarbon venting has safety concerns.
Recover refrigerant from all light commercial equipment to 0 psig before opening the system for repair - venting any regulated refrigerant is a federal violation carrying fines up to $69,733 per day (2026 rate).
