How to Fix AC Leaking Water in Nigeria

Split Air Condition or Cassette Air condition
November 14, 2025

If you’ve ever woken up to see water dripping from your air conditioner, you’re not alone. Many Nigerian homes and offices face this problem, the AC leaks water, and before you know it, your wall paint starts peeling or your rug gets soaked.

But don’t worry, it’s usually not a big deal. Let’s break down why your AC leaks water and the simple Nigerian-style fixes that work.

1. Clogged Drain Line

This is the number one reason most ACs leak. Dust and algae build up inside the drain pipe, blocking water from flowing out properly. When that happens, the water finds another route usually down your wall.

Nigerian Fix:
If you have a vacuum or a hand pump, gently blow through the pipe to clear the blockage. Or better still, call a technician from Aiki Services to flush it professionally.

2. Dirty Air Filter

When your filter is filled with dust (and Lagos dust doesn’t play), the AC can’t breathe well. The coil inside starts freezing up, and when the ice melts, it becomes water that overflows.

Nigerian Fix:
Remove your filter, wash it with mild detergent, let it dry, and fix it back. Do this every 2–4 weeks — especially during the dry season.

3. Low Gas (Refrigerant) Level

When your AC gas is low, the evaporator coil freezes, and as it melts, it drips water. This is another common reason your AC leaks water.

Nigerian Fix:
Don’t just top up the gas! Ask your technician to first check for leaks before refilling. Otherwise, you’ll be spending money every few weeks

4. Poor Installation or Wrong Tilt

If your indoor AC unit wasn’t installed with the right slope, water won’t drain properly. Instead of flowing out, it drips from the back or side.

Nigerian Fix:
Always use certified installers. A slight tilt can make the difference between a dry wall and a waterfall

5. Old or Rusted Drain Pan

Over time, your AC’s drain pan can rust or crack, causing leaks even if everything else looks fine.

Nigerian Fix:
Replace it simple. During your next servicing, ask the technician to inspect it.
