Air conditioners produce condensate water that needs draining through a primary line outside and a backup secondary line. If you see water dripping from the visible secondary drain, your primary line is clogged and needs immediate attention.
When you're talking about air conditioning, you're talking about removing heat from the house. Part of that removal of the heat, especially in this area, is dehumidification. We talked about that last week. The air conditioner is a dehumidifier. So to do that, moisture is taken out of the air. So the result of that, obviously, is water. So that water has to go somewhere. So upstairs you have a drain line. It sounds like you have a drain line, a primary drain line, and a secondary drain line. The primary drain line should be functioning somewhere where you cannot see it. It'll be outside, obviously, dripping somewhere. The secondary drain line, when that's installed, they always put it in a place where you can see the water dripping. I've even seen it. I've even seen it in the front of a house, at the front door. You know, drip basically on your head. When it starts dripping, like, oh, my goodness, that'll get your attention. But when that secondary line is dripping, it means the primary is clogged. So you're fixing to have a serious problem on your hands.
