Water dripping from the front of the indoor unit or down the wall during cooling.

Safety first: Turn off power to avoid electrical hazards from water.

Steps to try:

• Check unit level: Use a spirit level to ensure the indoor unit is slightly tilted toward the drain side.
• Clear drain line: Use a wet/dry vacuum at the drain outlet outside to suck out sludge and algae.
• Clean drain pan: Remove the front cover and gently clean the pan under the coil.
• Address icing: If the coil is icing, clean filters and coils and ensure adequate airflow.

When to call a technician: If leakage persists, the drain pan may be cracked or mis-installed and may need professional repair.
