A loaded evaporator coil does not fail politely. Airflow drops. The coil runs colder, and it ices. Melt water then overshoots the drain pan. That shows up as a brown ring on a hallway ceiling. Meanwhile the compressor works against low suction pressure. Waiting turns a cleaning into a parts job.

Here the fouling has local causes. Marine moisture meets a cold coil face and keeps it damp. Fine field and road dust rides in through filter bypass. In 1960s and 70s tract homes, the single central return is often undersized. Face velocity is high, and the coil packs fast. Wildfire ash seasons make it worse. Coastal condensers add salt film on the outdoor fins.
