Pooling Water In Your Air Conditioner: What Causes It And How A Plumber Can Help

Posted on: 28 September 2016

Window air conditioners are supposed to be installed at a slight angle in your windows. This allows the little drainage hole at the bottom to release rain water that falls through the part of the air conditioner that hangs outside the window. If water begins to pool inside the air conditioner, you can hire a plumber to help fix the problem. Here is how that works.

Evaporator Leaks

The evaporator inside older window A/C units often develops a leak. When that happens, not all of the condensation that heads into the evaporator gets to where it is supposed to go. It then pools in the bottom of the air conditioner and leads to puddles coming forward and sputtering and spitting out the front vent of the unit. Pretty soon you have a very wet floor in front of the unit. If you can, try to readjust the unit so that it tilts backward a little to allow the extra water flow out the  back. If that does not work, a plumber can assess the unit and install a hose that will extract the current excess water and then act as an additional drainage port.

Debris on the Outside Has Created a Chute for Rain or Blocked the Drain

It is kind of a fluke occurrence, but it does happen. Leaves get plastered to the outside of the air conditioner, creating pockets that collect rain and chutes into the unit that allow the water a direct path in. Clear all of the debris that you can see, and then consult the plumber. He or she may be able to construct a rain hood that will keep the rain off of the unit but still allow it to drip as it should to the outside. If debris has managed to get inside the unit or stuck on the underside of it, and it has blocked the unit's drain port, the plumber can help you clear out the port and unblock it so that it continues to drain properly.

Hoses Inside the Unit Are Badly Damaged

If you have corrected all of the fore-mentioned problems, and your A/C unit is still having a problem with pooling water, it may be that all of its internal hoses are completely shot. The plumber can open up the unit, replace the hoses for you, and then close it up again. If it still does not work, you may just want to consider replacing your air conditioner entirely.
