Aircon Leaking Water Inside the House? Here is Why And How

It’s a scorching summer day in Johannesburg. You turn on your air conditioner, relax into your couch, and ten minutes later, you notice a steady stream of water dripping down your freshly painted indoor wall.

An air conditioning unit leaking water inside the house in an emergency is one of the most common issues homeowners face. While it looks alarming, understanding the underlying causes can help you prevent extensive property damage.

Your air conditioner doesn't just cool your room; it extracts moisture from the humid air. This moisture collects in an internal drip tray and drains away through a small plastic pipe. Over time, dust, algae, and mold can clog this line. When the water has nowhere else to go, it overflows directly out of the indoor unit’s casing.

If your system is low on refrigerant gas or has a severely dirty air filter, the temperature of the indoor cooling coils can drop below freezing. Ice builds up across the metal fins. The moment you turn the system off, that ice melts rapidly, completely overwhelming the internal drainage tray and causing a sudden indoor flood.

If your system was recently installed or serviced by an uncertified handyman, the drainage pipe might not have a proper downward slope, or the internal connections may have slipped loose over time.

🛑 Step 1: Turn off the system immediately. Do not leave it running, as the water can seep into your electrical sockets or ruin your ceilings.
🧹 Step 2: Dry the area. Place towels beneath the unit to protect your flooring or electronics.
📞 Step 3: Call an expert. Clearing a deeply clogged line or balancing refrigerant levels requires specialized tools.
