Yes, the drain has either come loose, or clogged. Treat these as you would any plumbing problem. If the water isn't coming out at all where it normally does you can use some drain cleaner followe by plenty of water. If the line is broke you may need a 3/4 inch pvc coupling, pvc glue and a small hand saw to repair the drain pipe. There is a possibility that it is the pan has rusted through, which you would probably need help from a Pro. Good luck

    Hope you were able to locate the leak, sometimes they're hard to locate. Since water doesn't run uphill you can get an idea as to the general location by seeing where it exits the unit. I always need a good shop light to locate a leak. Air conditioners are like giant dehumidifiers, the more humid, more water. If you're still having the leak, let me know if your unit is split system and who the manufacturer and model number is, it's hard to help online with little info.

Why does my split ac unit leak inside the house?

This happens when the drain pipe is too high, or kinked. The pipe must be lower then the drain pan in order for the water to drain. This is a common problem.

Suddenly today the unit started leaking lots of water into the inside of the house. I've tried to see if outside drain is clear; I can't find it. I wiped dust off the inside coils. Tested again....

Best thing to do is take the unit out of the window, take the case off, and blow or wash out the entire unit. The drains are probably stopped up. Wash out would be best, but make sure the motor doesn't get we as well as the switches. Give it an hour or so to dry out before you plug it back in.

Leaking from inside unit

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,

Leaking water inside my house, not outside like its suppose to.

as you probably already know the main drain for the inside unit is stopped up and if you are able to open or cut the line to clear it and glue it back together with proper fitting the drain would then work correctly. Any basic a/c guy can do this for you also.

A.C. unit is draining on the inside of the house.

There is a drainage and it is stucked with dust, mold etc. Just open metal lid on the wall inside your house, where the coil is installed and where you're changing filters, remove air filter, there at bottom you will see the drainage hole (now under water probably). Rent an air compressor from Home Depot or Lowe's, stick the hose to that hole and turn compressor on. This shall blow the drainage through. After that slowly pour 1-2 cups of Chlorox or Tylex in there, let it stand for 15 minutes, then pour some more water and blow with compressed air again, then flush it with water and blow last time.
Do that at least once in two years, or you gonna have same problem again.

Just had a lot of rain. Water was leaking into

You'll probably find that the alarm control unit got wet - it is sometimes located under the drivers or passengers seat, or under the kickpanels/dash - You may find that it dries up and works OK, or never works right again - I'd recommend fixing the leak first, then moving on to the alarm system... I'd be cautious with introducing H20 to the alarm control unit, as they can disable the vehicle from starting or running...

Brand new whirlpool cabrio began leaking

Sounds like you may have a small hole or a failure in a seal somewhere, is there a filter on the drain you could check this is secure and free from debris, is it possible that the drain hose has been kinked during a spin and possibly leaked? if it only leaks when it drains it is defenatley somewhere in the drain system. I would use your Insurance on this one Top loaders can be difficult to work with as the space inside them is very limited.

Tilt the unit toward the window opening and clear the drain holes in the back and bottom of the unit from debris.

Air conditioner leaking

Hi, There are no pipes, just passage ways on a window unit. It probably needs cleaned. Window units naturally create water in the evaporator area. The water is suppose to drain to the back of the unit through passage ways to the condensing area where the slinger ring on the condenser fan blade slings it into the condenser coil making it more efficient. There is usually a drain hole to drain excess water from the back of the unit. Any dirt or algae in the pathway of this water or the wrong tilt will cause water to build up and drip or blow out the front. Anything touching the evaporator coil allowing water to run down the obstacle into the wrong area will cause the same thing. reduced air flow will cause the evap to freeze which could also cause a water problem. Since the tilt is right and it doesn't seem to be freezing, Maybe a temporary increase in tilt and a dropper of bleach at the base of the evaporator would do it. This will kill the algae and may unblock the water flow. NOTE: It may also cause stains on a carpet or floor if the bleach water drips onto it. If you want to pull it out and clean it, most units can be pulled out of the housing and sprayed with a water hose but you need to be careful not to get water in the electrical parts of the unit. They can be covered with plastic or foil. Make sure you unplug the unit before trying to remove it. You may have to remove some screws to remove it from the housing. Hope this has helped. kstfas
