Freon recovery or pump down into condensor

To change indoor TXV on a heat pump system Is it possible for the Freon to be pumped back into a micro channel heat pump condenser ? Or does if have to be contained using a recovery machine & tank?

    A microchannel coil may not hold the complete charge.

    & scroll compressors shouldn't be pumped down to low pressure so you gotta use a recovery machine anyhow

    Basically recover whole system & weigh back in best bet this would save time on the start Up or Is it advisable to close down liquid & suction line ports recover evaporator & line set ? Just seems like there should be other options to service equipment, Thanks for any suggestions it is appreciated,

    If refrigerant was originally added to the factory charge, then recover. Either way, a triple vac should be done. Good time to replace the liquid line drier too.
