Hi all. I just bought a 5 room flat and I am wondering if there is such a thing as 'aircon re-wiring'? I tried googling for this but couldnt find much info on it. We have 4 bedrooms but the current air conditioning split unit is such that the 4th aircon is placed in the living room. I would like the 4th aircon to be placed in the 4th bedroom instead.
