Amana air conditioner leaks water outside excessively, causing staining or puddles below the unit.

Safety first: Turn off the unit before working around the outdoor section. Use caution on ladders or exterior walls.

Steps to manage outdoor water leakage:

• Inspect condensate management parts: On many Amana window and PTAC units, a splash ring or slinger ring on the condenser fan helps re-evaporate water. Ensure it is intact and properly positioned.
• Check drain spout: Verify that any external drain spout or adapter is not cracked or missing. Replace if needed.
• Clear channels: Clean any channels or troughs that direct water to the condenser fan area.
• Consider drain kit: In very humid climates, install an optional Amana condensate drain kit to route water to a safe location.

Some water discharge outside is normal; focus on preventing damage to building materials or walkways.
