What is actually going on
Water dripping from the indoor wall unit onto the floor or furniture below.
The realistic causes, in order
A blocked condensate drain, usually biofilm build-up in the drain line A condensate pump that has failed or a drain run with an incorrect fall Ice forming on the coil then melting past the drain tray, which points at low charge or restricted airflow
What we test on site
Condensate route from tray to termination and whether it falls correctly the whole way Pump operation and float switch, where one is fitted Whether icing is occurring, which changes the diagnosis from drainage to refrigeration
Get an air conditioning unit leaking indoors diagnosed properly
Clearing and correcting the condensate route usually fixes it permanently; icing faults need the refrigeration side investigating.
Questions we get asked
Why is an air conditioning unit leaking indoors happening on an air conditioning system?
A blocked condensate drain, usually biofilm build-up in the drain line
What normally puts an air conditioning unit leaking indoors right?
Clearing and correcting the condensate route usually fixes it permanently; icing faults need the refrigeration side investigating.
Is it safe to keep using the system with an air conditioning unit leaking indoors?
Water dripping onto electrical equipment or into a ceiling void should be treated promptly. Turn the unit off rather than running it with a towel underneath.
