Condensate Drain

When your mini split cools the air, it pulls moisture out of it — that moisture has to go somewhere. The condensate drain is the line that carries that water away from the indoor air handler and out of your home. If it gets clogged with algae, debris, or sediment, water backs up and can leak out of the unit onto your wall or floor. A clogged condensate drain is one of the most common reasons people see water dripping from their indoor unit. Clearing it is usually straightforward, but if the drain line wasn't installed with a proper slope, it can be a recurring problem.
