One of the most common issues that people deal with is when water is pooling next to the air conditioner itself. One thing to keep in mind is that air conditioners and other high efficiency combustion furnaces will often create quite a bit of condensation which will then exit through a plastic drainage tube. If everything is set up correctly it should go into the floor drain or at least be carried away by a small condensation pump. If in fact the water is flowing at the base of the unit, something is likely very wrong and it's probably being caused by either something obstructing the waters flow itself or a pump that might be malfunctioning.
The first thing that you need to do is to look and see if one of the tubes is leaking and if in fact it is leaking you need to make sure you replace it immediately. The next thing we need to do is actually test the condensation pump by pouring water into the pump's hand. If after you pour the water into the pan it does not start up, that is a sign of two things, either the unit is broken or it is not receiving power. The way that you can verify this is to make sure that the unit is in fact plugged in and then tested a second time and also test of the circuit. If it still does not turn on and operate, it likely needs to be repaired or replaced by a professional.
If the pump does indeed run but does not empty the pan, the check valve that is located just before the discharge tube is probably stuck. What you need to do is unscrew the check valve, loosen up the ball that is inside, and then look for the obstruction and remove it. The final thing you need to look for is to see if ice might be blocking the tube. If you found this to be the case, make sure that the filter itself is not very, and if it appears to be in okay condition, then that means that they are conditioning units refrigerant supply is probably too low. With a problem like this, you need to call professional technician.
