Water pooling or leakage is a common indicator of a blocked drain line in air conditioning systems. When the drain line, which is responsible for removing condensation produced by the evaporator coil, becomes clogged, the moisture that normally flows out can back up. This results in water accumulating in various parts of the system, which may lead to pooling beneath the unit or leakage in other areas. Not only does this pose risks for water damage and potential mold growth, but it can also signal more significant issues within the air conditioning system that need to be addressed to ensure proper functioning.

In contrast to this, high energy bills could be caused by various inefficiencies, frequent cycling of the compressor might indicate a range of operational problems, and noisy operation may stem from mechanical issues unrelated to the drain line. While these symptoms are certainly worth investigating, they do not specifically point to a blocked drain line as clearly as water pooling or leakage does.
