Just bought an EA in Sembawang and unit is furnished with System 4 Inverter brand is Fuji Electric. Have never heard of this at all, did surfing for it but cant find much on it. Does anyone has any advice for us on this? The aircon is about 7 years old and I was thinking of going for a chemical wash for it. I asked a A*re company to quote for me and was told that they charge about $180 for ONE AIRCON chemical wash as they will bring the whole thing down bla bla..
We have tested the aircon and it seems fine but just to be on the safe side money wise, we decided just to go for a chemical wash instead of changing the whole system. Should we just go for normal cleaning or chemical wash? thanks heaps..
