Overview
Air conditioning systems remove moisture from the air as they cool. That moisture drains through a condensate drain line. If the drain line becomes clogged, water can back up and leak into the home, potentially causing damage.
Drain line clogs are commonly caused by algae buildup, debris, or lack of routine maintenance.
