Where the Water Is Coming From
A working aircon pulls litres of moisture out of the air every day. That water collects in a tray under the indoor coil and runs out through a condensate drain. When something blocks that drain, the tray overflows — and the first sign is usually water dripping from the bottom of the indoor unit, or a damp patch spreading down the wall beneath it. Our Wellington aircon team clears it and checks why it blocked.
Deal With It Early
This is the aircon fault most worth calling about quickly, because the unit itself is rarely the expensive part. The plastering, painting and occasionally the ceiling below are. Algae and dust build up inside the drain line over a season or two; we flush the line, clean the tray, check the fall on the pipe and make sure the outlet actually discharges somewhere it should. Where the drain was badly routed at installation, we re-route it properly.
When It Is Not the Drain
Water can also appear because ice has formed on the indoor coil and then melted — which points back to low refrigerant or a badly restricted filter rather than a drain problem. A cracked drain tray, a loose pipe joint inside the unit, or an indoor unit that was never mounted level will all do it too. The technician checks which of these it is, rather than just flushing the line and leaving.
