What are the two refrigerant recovery methods?

The three different recovery methods are: vapor recovery; the push-pull method; and the liquid recovery method. In the vapor recovery method, the refrigerant is removed from the HVAC system in a vapor state. The vapor is then condensed into a liquid by the recovery unit and transferred to the recovery cyclinder.
