Have been reading a little in this forum.Will be getting my 4 room soon & was at the creative living fair at expo last week.Am looking at a inverter system 3. 2 units for the bedroom(1 room will not be airconed) & a big unit for the living coz we entertain about 15 people once a week.Fusion Air(the stall at the show) recommended Starmex.About $3.3k.Anyone use them before? Sorry but know nuts about aircon
