Why Is My Air Conditioner Leaking Water?

That pool of water under your air conditioner hasn’t disappeared. In fact, it might even be getting bigger. What are you going to do next? What actually causes an air conditioner to leak water like this? The answer may be closer than you think.

Water Is Part of Your Air Conditioner’s Job

The goal of any air conditioner is not just to keep your home cool, but also to grab any humidity from the air and get rid of it. The blower inside your air conditioner grabs that hot, humid air through the return vents, then runs it through the evaporator coil to help cool it and return it to the inside of your house. During that process, though, condensation forms on the coil. That condensation falls into a drain pan, then down the drain line, which leaves your home close to the outside unit.

When It Doesn’t Work Like It Should

So, why is that water not leaving the drain line like it should? There could be several reasons for your air conditioner leaking water. It could be that the drain line itself is actually clogged. Dirt, mold, and many other things can clog the drain line. Because the drain is clogged, the water has nowhere else to go. It could also be that the evaporator coil isn’t performing as it should. If it gets dirty, the dirt can mix with the water, then fall into the pan and clog the drain.  The drain pan may also be malfunctioning. It might have rusted through, which means the water never actually makes it to the drain line.
