Daikin System 4 Aircon Singapore
4 rooms, one outdoor unit. Official Daikin configurations with one transparent installed price, from $4,739.
What a System 4 is
A System 4 runs four indoor fan coils off one outdoor unit: typically three bedrooms plus the living room, all from a single ledge spot. It is the whole-home solution for 5-room HDB flats, executive flats and many condos.
The Daikin System 4 lineup we install runs on the iSmile Eco+ MKM85ZVMG or MKM100ZVMG outdoor units with CTKM fan coils, all 5-tick on R32.

The honest part
When every room runs at full blast together, the outdoor unit shares its capacity between them per the official combination tables, so each room gets a little less than its solo rating. For the usual pattern of bedrooms at night and living room by day, you will never feel it. If your household genuinely runs everything hard at once, tell us at the site survey and we will size honestly, even if that means a bigger condenser or splitting into two systems.
