1. Blocked Drainage (Drainage) Channel
Goo and dust that accumulate in the drain pan will clog the drain holes, causing water to overflow and drip into the room.
2. Installation Pipe Not Sloped
The drain pipe installation must have a slope so that water flows by gravity. If it is level, water will be held back.
3. Ice Formation on the Evaporator (Freon Deficiency)
A lack of freon can cause the evaporator coil to freeze. When that ice melts, the water drips out of the drain line.
Quick Solution
Turn off the AC immediately. Move electronic devices underneath it. Schedule a thorough AC cleaning right away to clear the clogged drain holes.
Field Notes from the Pandan Teknik Technician Team
The article above provides a general overview of issues we frequently encounter in the field. However, each AC unit and room has unique characteristics (such as pipe installation length, ventilation, and heat load). If you notice similar symptoms on the AC in your home or business, it is best not to jump to conclusions on your own. You can contact the Pandan Teknik team via WhatsApp to describe the complaint in detail. We will help analyze whether a simple service, spare part replacement, or a technical survey visit is needed so that the repair is targeted and cost‑effective.
