Water leaks from an air conditioner can signal various problems. Understanding causes helps prevent costly damage.

Clogged Condensate Drain Line

Drain lines can become blocked with algae or debris, causing water to back up.

Flushing lines regularly keeps water flowing freely.

Damaged or Rusted Drain Pans

Cracks or holes in drain pans lead to leaks beneath the unit.

Replacing pans promptly prevents water damage to surrounding areas.

Improper Installation or Pitch of Drain Lines

Incorrect slopes can impede drainage, causing water pooling.

Professional installation is key to proper system setup.

Frozen Evaporator Coils Causing Excess Water

Ice melts as the system turns off, producing excess water beyond drain capacity.

Addressing airflow and refrigerant problems reduces coil freeze risks.
