To perform a pump down in an indoor unit, first close the liquid line valve near the condenser. Run the AC system, allowing the compressor to move all refrigerant into the condenser. Monitor the low-pressure gauge until it reaches near zero. Then, quickly close the suction line valve and turn off the system. #PumpDownProcess #HVACMaintenance #ACRefrigerant #IndoorUnitService #CompressorPumpDown #RefrigerantRecovery #HVACRepair #CoolingSystemMaintenance #ACTechnician #SuctionLineValve #acrepairin
