The process isn’t complicated. Part of your HVAC system is known as an evaporator coil or indoor coil.
It is housed inside the furnace or air handler or on top of it. The coil gets very cold when refrigerant travels through it and collects heat from your house.
As indoor air passes over the coil, not only is heat removed from it but some of the moisture from the air condenses onto the cold coil. The resulting water then runs into a drain pan.
The pan has a hose attached that typically runs to a drain in the floor. When the drain is clogged, the condensed water will leak, plain and simple.
