- It is registered with EPA by the technician
- It is certified by the organization that tested and certified the technician
Why “It is certified by an EPA-approved equipment testing organization” is correct

Why the other answers are wrong
- It is approved by the chiller manufacturer — Chiller manufacturer approval does not meet the federal certification requirement.

- It is certified by the organization that tested and certified the technician — Technician certifying organizations do not certify recovery equipment.
