I have two Fujitsu Split Air Conditioners which are leaking. One dripped water, the other has ruined the wall covering where water was apparently collection around it. Does this sound like something I will need a repairman for?

there might be a crack on the drain hose

chances are either the unit is not level or the drain hose is not pitched properly going through the wall when water is leaking is there water coming out of the hose outside

Take the cover off the inside unit and look for the drip pan under the evaporator coil. It should have either one drain in the middle of the pan or a series of smaller drains along the back of the pan. The drain(s) is probably clogged up and causing the pan to overflow into your home. Also check the drain line on the outside wall where the refrigerant lines come through the wall for a blockage.

Water leak is the common issue in split a/cs. Due to coil,air filter, drain pan dust blocked, less rpm of blower motor, short of gas.
If service for the unit is more than 4 months, please do it first. And then check rpm of blower motor, if less replace capacitor.
Check gas pressure. Must be 60 PSI @ 98*F, of ambient temp. If less than that find leak and arrest and do gas charging. Thanks.

Normally, an Air Conditioner removes water from the air and that water condenses on the coils of the inside section that does the cooling. The water condenses on the cooling coils just like moisture condenses on the outside of a glass of ice water.
This excess water drains out of the cooling section through a "drip tube" and is supposed to drain outside of the house, or a drainage system. Your "drip tube" has either not been installed (if it is a brand new installation), has separated and water is now dripping into the house instead of outside of it. Or it is clogged. This happens when algae builds up inside the "drip pan". If that is the case, you can purchase "algaecide" tablets which kill the algae that is clogging the drip pan and preventing water from draining out through the drip tube. These tablets can be found in many hardware stores, refrigeration supply companies, or even Walmart. You can put a tablet inside the pan. (You will have to remove the cover of the unit). You can often use a little bit of Bleach and that will act as an algaecide. Hope this helps,
Best, Mark

If the unit is mounted on an outside wall check the condensate drain that comes out with the line-set to the outdoor unit. If the pipping goes up into the attic than you have a small condensate pump that may have failed. The float in the pump may have stuck in the down position not allowing the pump to come on.

your condensation line is blocked

if your indoor unit is leaking water down the wall,it is from one of two things.First, is possibly the insulkation on the copper lines is coming loose and the suction line is condesated,with no way to drain,it drips down the unit.The other possiblity is that the drain hose is coming loose from vibration and leaking a little.

drain line is more and likely stopped up

 during Cooling and Dry modes, if the unit is used under conditions of
lower temperature (18C)  the heat-exchanger may freeze, leading to water leakage and other damage.
If the unit is used for long periods under high-humidity conditions, condensation may form on the surface of the indoor
unit, and drip onto the floor or other objects underneath. (About 80% or more)


Increase Temp to 20 and also run coil dry cycle,
