Ask the HVAC tech. I believe the used refrigerant (R-410A?)

can be re-used.  The tech can recover the refrigerant from the system, add back the accumulator (critical for high pressure system), pressure test the system for leak detection, then evacuate -pressure hold, add back the used refrigerant, test the system for normal operation (high and low pressures, subcooling temp per spec).  This may take several hours.  The old accumulator may be irreparable (the HVAC tech can tell you) and thus a new accumulator is needed for replacement.
