Water dripping from the indoor unit front panel or onto the wall/floor.

Safety: Turn off power before opening the indoor unit. Be prepared for water spillage.

Steps:

• Check filters: Dirty filters can cause coil icing and overflow. Clean filters thoroughly.
• Inspect drain pan: Remove the front cover and look at the drain pan under the coil. If full of water, the drain is likely blocked.
• Clear drain line: Locate the drain hose outlet outside or at the building drain. Use a wet/dry vacuum to suck out clogs from the outlet. You may also gently blow air from the indoor side if accessible.
• Check unit level: Use a small level to ensure the indoor unit is slightly tilted toward the drain side. Adjust mounting if necessary.
• Inspect hose connections: Ensure the drain hose is firmly attached to the pan spigot and not kinked or cracked.

Technician involvement: If leaks persist or if the coil repeatedly ices over, a technician should check refrigerant charge and airflow in more detail.
