Water dripping from the outdoor unit or piping during cooling operation

Safety first: Be cautious of slippery surfaces around the outdoor unit.

• Identify source: Determine if water is coming from the outdoor coil area (often normal) or from refrigerant piping/indoor drain outlet.
• Check pipe insulation: If the larger copper line (suction line) is sweating and dripping indoors or on walls, its insulation may be damaged. Replace or wrap with closed-cell insulation.
• Verify drain termination: Ensure the indoor drain hose terminates in an appropriate location where water can safely drain away.
• Normal operation: Some water dripping from the outdoor unit in cooling is normal, especially in humid climates.
