Excessive leaking The carrier unit has a drain pipe that come off of the unit it also has a peice of pipe that comes off of the unit and points staight up about 4-5 inches, in between these two is a little hole where you can actually see the water flowing. the unit is leaking from this point at different times during its cycle. Why? and How do I fix this?

If this unit is new more than likely the condesate drain line does not have a deep U shaped "trap"in it. This allows the negative air pressure inside the unit to draw air up thru the drain line holding the water inside the cabinet until the fan shuts off, then the water can drop out of the unit everywhere.

If the system has been in foe some time and has the proper "trap" the drain line could be plugged any where there is a turn in the pipe. It is a messy clean out but it can be done by cutting the straight PVC pipe, right after the screw in fitting and the 90. This will allow you to unscrew the fitting at the unit and clean it out. Sometime there is a gel like clog that grows at this point. Then you can take a wire or compressed air to clean out the rest of the line to the outlet. Next pour hot water thru the PVC and see how it comes out the end. Worst case you will need to pour a solution of hot water and white vinegar to remove any build up.

If the whole drain is free of debris then you probably have a cracked drip pan under your evaporator and it will need replaced. A service technician will need to remove the coil and check the pan for breaks and cracks.

The water is syphoning out the drain. Make sure the drain hose is not sealed to the drain stand pipe it drains into, and make sure the top of the drain stand pipe is higher than the washers tub. Try to extend it with a coupling and a peice of pipe up to 36 inches.

What is leaking? If it is water, you need to find the drain pipe leading from the inside unit to the outside of the house, and open up the obstruction in it. You could push a wire up through it, or send some compressed air up it. The drain pipe is probably near the ground next to the foundation or in the ceiling of an outside porch.
If this is a window unit leaking water you need to clean the obstruction out of the drain pipe or hole on the outside of the window, probably at the bottom outside rear of the unit.
I wasn't sure from your question if it is leaking water, or leaking refrigerant gas. If it's the gas you probably need to call an A/C repair service.
good luck,

Sometime the water gets condensate by cond.coil heat. Excessive water will be drained out thr' pipe to b connected with hose in the unit.

May be your drain hose is worn out and leaking. Replace new long hose and connect to main drain pipe.

Most probable cause is a clogged drain line or a drain that is not properly pitched. Ensure the unit is level and that the drain line is properly pitched and clear. Some units are equipped with a small condensate pump. The unit will leak water if the pump is not working properly.

Can you get to the hose in the house unit? If so canned air

DOES THE HOUSE FEEL DRIER IF IT IS 80 OUTSIDE WITH ALOT OF HUMIDITY THE UNIT WILL RUN FOR A LONG TIME TO REMOVE THE MOISTURE(HUMIDITY) OUT OF THE HOUSE BEFORE TEMP DROPS DRAMATICALLY IS THERE WATER COMING OUT OF THE DRAIN PIPE OUTSIDE

Make sure that the flexible pipe is securely connected to the drainpan, it can come adrift and cause leaking. The way to check this is to make sure everything is dried out completely. Then open the front grill and carefully pour water so that it goes only into the drip pan. Pour slowly so that you do not overflow the pan. If water is coming out on the outside and you have no leaks on the inside, then you can rule out the perished or disconnected drainpipe theory. In this case your unit may be short of refrigerant causing excessive run time and a freeze up of the evaporator.
