Our aircon service expert recommended that we run our Fujitsu split systems on Dry for 20 minutes or so after operating them in Cool mode so as to dry the moisture off the evaporator coils and their fins so as to reduce the build-up of mould.
These systems build up mould in tropical environments like Cairns which eventually causes the tiny drains in the indoor units to block up, and results in water flowing down the inside walls where they are mounted. The mould would also have health risks associated with it.
We have him professionally service our split systems each year which takes around 2 hours per system, and the interior of the indoor units looks absolutely disgusting before he starts, and sparkling clean when he finishes.
