Question about Fujitsu Heating & Cooling
Model AST30RBA-W We've cleaned the filters and the water only drips out of the louvres not down the wall. We were advised to turn it on full power on either cool or dry due to humid Sydney summer and it's dripping. Normal water outlet pipe is dripping water too (normal). Any help please!

HELLO .. HOPEFULLY YOUR UNIT SLIDES OUT OF THE A/C HOUSING, IF IT DOES REMOVE IT. (THERE MAY BE A FEW SCREWS HOLDING IT IN PLACE USUALLY BEHIND THE FRONT GRILL) PUT DOWN SOME OLD RUGS FIRST AND HAVE SOMEONE HELP YOU SLIDE IT OUT. GET OT THE GARDEN HOSE AND SPRAY NOZZLE. PROP UP THE FRONT OF THE UNIT SO IT DRAINS TO THE REAR. BOTH THE EVAPORATOR COIL AND CONDENSER COILS SHOULD BE CLEAN. YOU WILL NOT SEE DIRT ON THE OUT-SIDE OF THE COIL ... IT WILL BE ON THE INSIDE HIDDEN BY THE CONDENSER FAN BLADE. BE VERY CAREFUL NOT TO BEND THE FAN BLADE WHILE INSPECTING OR WASHING. BE EXTREAMLY CAREFUL TO COVER THE MOTOR AND ELECTRICAL CONTROL BOX WITH PLASTIC BAGS TO ENSURE ALL ELECTRICAL COMPONENTS STAY DRY. FACTOID: 90% OF AIR CONDITIONERS THAT "DONT COOL AS WELL ANYMORE" IS DUE TO DIRTY COILS. THERE IS ALSO A TUBE OR CHANEL THAT DRAINS THE WATER FROM THE EVAP (FRONT) COIL TO THE BACK OF THE UNIT. THAT CONDENSATE WATER IS SUPPOSED TO ACCUMILATE IN A SNALL RESEVOIUR WHERE THE SLINGER RING ON THE OUT SIDE COIL FAN BLADE PICKS IT UP AND HELPS COOL THE HOT CONDENSER COIL. SOME OLDER UNITS MAY NOT HAVE A SLINGER RING AROUND THE OUTSIDE OF THE BLADE. NOW ... MAKE SURE YOUR OUTSIDE FAN BLADE IS CLEAN. AS WELL AS THE INSIDE BLOWER FINS ON THE "SQUIREL CAGE". NOW THAT YOUR UNIT IS CLEAN AND YOU CAN SEE CLEARLY THROUGH BOYH COILS, GO AHEAD AND OIL YOUR MOTOR. CHECK TO SEE IF YOUR FAN MOTOR HAS "OIL CAPS" USUALLY THEY ARE AT THE TOP OF THE 2 ENDS OF THE MOTOR. IF THERE ARE CAPS REMOVE THEM AND USE A STRAIGHT WEIGHT (NON-DETERGENT OIL). SOME WINDOW A/C'S UNDER 12,000 BTU'S ARE SEALED UNITS. IN THAT CASE YOU WILL HAVE TO REMOVE THE UNIT FROM THE WINDOW MOUNTING BRACKET. AND FOLLOW THE SAME PROCEEDURE AS LISTED ABOVE. GOOD LUCK AND STAY DRY.

Yes, if the filters are clean, the coils are clean, and it is still freezing up in cooling mode, then it is low on refridgerant.

SOURCE: Water dripping from air con use
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.

I will star checking freon pressure but you going to call an HVAC company to do that. Please turn it off or you will damage the compressor, if is not already.
