Tip & How-To about Heating & Cooling

Water in Air Conditioner

Air Conditioners are designed for two purposes.

1. Cool
2. Dehumidify

The water that collects in the drain pan is used to cool the condenser.
This is done by the "slinger ring" attached to the condenser fan blade thus making a more efficent unit.

Be sure the unit is tilted properly by using a bubble type level. The unit should tilt 1/4 bubble outward.

I have a sharp window AC unit, model af-609x. does it have a drain hole? there is no water coming out of it, but when we take it out of the window we get soaked from water somewhere inside the unitl


All window air conditioners will remove moisture from the air if there is any. Most window air conditioners collect this moisture in the bottom pan of the air conditioner and attempt to evaporate the moisture. The evaporation process works as follows: First, the water drips down off of the cold evaporator coils on the front of the unit. Then the water collects in the bottom of the air conditioner base, the "pan." If the air conditioner is installed properly it will be tilted slightly back.

The water then collects near the back of the unit. On some units, the fan blade used to cool the rear condensing coils will have a rim on the outside of the fins of the blade. This rim, or "slinger," will come close to touching the inside of the air conditioner pan when the fan is spinning. As the water collects in the pan and reaches the depth necessary for the fan ring to touch it, the ring will lift some of the water up and the fan will blow it at the condensing coils. Because the coils are warm, they will evaporate the moisture to the outside.

While this is happening it is normal to hear water splashing and sloshing around. As long as there is no water leaking inside the room that is being cooled there is no cause for concern.

Never drill into the bottom of and air conditioning unit to "let the water out."

Water in the drip pan- what is causing it?


I assume you are talking about the indoor unit. One function of the a/c system is to dehumidify the air. Condensation forms on the cooling coil and runs to the drip pan. There should be a drain line on the drip pan that drains the pan outside. These sometimes become clogged causing the water level in the pan to rise. Try some mild drain cleaner to open the line. Hope this helps. Let me know what you find.

DE500P Dehumidifier: Does not dehumidify even though set to dehumidify. Fan will turn on when RH above setting, and stay on, since humidity doesn't drop. Filter is clean & pail empty.


Locate and touch the cooils located, usually, above the condensate collection pan, ("pail empty"). If the coils are not cold, or cool to the touch, the unit has lost its charge of refrigerant. This would explain why the unit fan is working, but there is no condensate, as there is no coolant (charge) to cool the coils and "pull" the hunidityout of the air.

water is filling up in drain pain


My suggestion is to NOT pull the plug on the drain that should be covered with a sign that says...do not remove plug. Water is supposed to be kept in the pan. The interior wheel then helps the water keep the condenser cool....Ron
