Hi, not sure about correct place to ask this.
I am looking for information about ducted system, to be installed in residential building. So far I googled, there is very few information about ducted system in Malaysia (I get redirected to Australia and New Zealand websites instead).

As I know, recently many high end landed residential slowly change to ducted system as it is more pleasing to the eye both indoor and outdoor. And there is also advancement in "zoning" technology so you don't have to cool rooms which are not occupied.

I understand that split system is the dominant choice for almost all Malaysians. Anyone care to share any research or survey done for ducted systems?

Thanks!

anyone know to install aircon, whether it has difference for single phase and 3 phase wiring?
especially for the switch on the wall connect to indoor unit.

so there is no difference...
cos i heard 3 phase have 3-wire and 4-wire system.. so i thought maybe the number of cables to the aircon got additional..
