You need to seal the portion of the air conditioner that is inside the window from the portion that is outside the window, Sweating is caused by moist outside air leaking in and contacting the cold portion of the air conditioner. Do not use duct tape, buy aluminum tape which is what professionals use to seal air leaks on ducts. Home Depot sells the tape. Buy the smallest quantity you can find that will do the job ( it can be expensive ) unless you plan to go into air conditioning duct installation.
For best results use some form of insulation over the accordian like side baffles ( cut to fit) . Styrafoam from packaging or silver backed insulboard (Home Depot). Now tape the sides of the insulation to all sides of the window frame, bottom of the window, the sill, and the air conditioner.
Unless you enjoy doing this every year - plan on this being a permanent installation. It is a tedious job because the aluminum tape is not very forgiving and has a peel off backing but it sticks forever.

Hi; Is the drain for the condensate draining. You will have to check the top unit to see if water is present. You can also check the air filter to see if it needs to be cleaned. Please only use a household cleaner and hot water on the filter screen. Also what is the inside temp. when You notice the sweating. If Your in a very humid climit some times the unit will sweat until it can remove excessive moisture from the inside space. Also does the tstat seem to be working normally and holding temp. ...alpharome416
The root cause is the temp of the lines are below the Dew Point of the surrounding ambient air. Improper charge, low load/ air flow, wrong insulation, improper superheat, are all items that can cause this condition. You may have to look further into whats going on.
The evaporator coil will sweat condensation from it during normal operation. this can accumulate to quite a bit of water by the day's end. I would check to see if the drain pan under the coil is plugged or the drain line that (Should) be attached to it. Finally it could simply be off balance causing the water to overflow out of the pan.
Your inside cooling coil in the air conditioning mode could be frozen over. Change the fan setting to on and operate it that way when in the cooling mode. Turn the air conditioning OFF with the fan ON to clear the coil of frost which should take about 1 hour.
The fact that you have sweat on the large line means that the temperature of the gas inside the line is below the due point of the moisture in the air. A good tech would measure the pressures and temperature of the system to get what is called superheat to determine proper system charge of refrigerant.
