    Answer: Recover the existing refrigerant

    Recovering refrigerant first prevents illegal venting and protects the technician.

  6. Why should refrigerant cylinders never be overfilled?

    Answer: Risk of rupture from thermal expansion

    Overfilled cylinders can rupture when liquid expands with temperature increases.

  7. Recovered MVAC refrigerant that is recycled on-site must meet purity standards set by:
