AC dripping water inside but drain pan not clogged
A steady drip can form above the blower wheel or near the filter even when the drain line has been cleaned multiple times and the pan is not cracked or full. The unit often stops cooling alongside the leak. Because standard repairs fail to last, owners are stuck calling technicians back every few weeks for repeating drips, even on brand new units.
