Replaced compressor and the suction line bottomed out not allowing any refrigerant to go to the compressor. During further inspection I found that the system had two filter driers installed originally, replaced the outdoor filter drier already. Pumped system back down and removed the second filter drier, TXV has failed not allowing system to operate correctly. Need to order txv and return to install as soon as possible System is pumped down and ready for txv to be replaced. Explained to cust what was going on and they understood. Only doing a pump down charge on the txv replacement since most of the labor is already completed, OK by Mark W
