    Common Causes & Solutions

    Clogged Drain Line

    DIY Fix

    Algae, mold, or debris blocking condensate drain.

    Solution: Use wet/dry vac on drain line outlet or flush with distilled vinegar.

    Dirty Air Filter

    DIY Fix

    Restricted airflow causes coils to freeze, then melt excessively.

    Solution: Replace air filter and check for frozen coils.

    Cracked Drain Pan

    Call Pro

    Rusted or cracked condensate pan can't hold water.

    Solution: Professional drain pan inspection and replacement.

    Frozen Evaporator Coils

    Call Pro

    Ice buildup melts faster than drain can handle.

    Solution: Address underlying cause of freezing (see frozen coils guide).

    Improper Installation

    Call Pro

    Unit not level or drain line improperly pitched.

    Solution: Professional re-leveling or drain line correction.

    Low Refrigerant

    Call Pro

    Low charge causes coil freezing and subsequent water overflow.

    Solution: Professional leak detection and refrigerant recharge.
