It probably does- you just do not see it. Newer AC units have a "slinger" fan. Condensed water is caught by the outside fan, and blown into droplets. This eliminates the trickle of water dribbling from the AC.
That is condensation and it is normal for water to come out of an air conditioner in the back of it.
No, you have to call a repair man to come do it for you, unless you have to have a licences to work with freon.
No easy way of doing this. These units do not come with service valves.
I have seen this where water has leaked into the ductwork and stagnated.
No. In so doing you have reduced to nearly zero its cooling capability.
Portable air conditioners come with a vent hose that can be placed in a nearby window or vented through a hole in the wall like your clothes dryer.
Just as a cold can of coke will bead moisture, so does the cool surfaces of the AC unit.
fair chance the drain hose for the a/c has come out of where it is supposed to plug in.
Come to My Window was created in 1993.
perhaps it is water from the air conditioner, sometimes the drain hoses come loose.
If there is water in between the panes of your window i would suggest calling a contractor to come and replace the window, simply because there could be a gap or crack in your window that is allowing water or other materials to seep through which in the long term could cause other problems. It could also cause air to flow out or air to come in which could be costing you extra money for air conditioning.
The AC system doesn't use water. Water may be produced at the evaporator as a result of the rapid exchange of heat to the ambient air, but there is no water in an AC system.
