The Goodman B1789882 Piston Kit is a genuine OEM metering component for GSC130483AD 13 SEER air conditioner systems.

OEM vs. Generic

Piston bore size is matched to the system's tonnage and coil. The genuine Goodman B1789882 carries the exact factory orifice diameter, so the system meters refrigerant as designed. Generic or mismatched pistons can cause low capacity, freeze-ups, or compressor flooding. With metering devices, OEM precision directly protects efficiency and the compressor.

Installation Difficulty

Advanced (4/5). Replacement requires EPA-certified refrigerant recovery, opening the sealed system, and proper evacuation and recharge. This is a job for a licensed HVAC technician. Disconnect power and recover refrigerant before service.

Compatible with GSC130483AD. Verify your model and tonnage before ordering.
