From the drain pan, the water travels out of the house through the condensate drain line.

If the drain line gets clogged, then the water will back up and eventually drip out to article floor. Which is the ceiling in the room below it.
Using a shop Wet/ Dry Vac to vacuum the line at exit outside is the easiest way to remove the obstruction.

Many drain lines rely on gravity to transport the condensate from the air conditioner outside of the house. But in some cases that is just not possible, for instance some HVAC sore in the basement which is below the main floor line.

In this type of situation a condensate pump is needed to pump the water from the AC outside.

If the condensate pump is not working or leaking , it is not going to be able to transport the moisture outside and the result will be water overfilling the drain pan and leaking inside your home.
