A ducted split system is essentially the same technical system as the above-mentioned split system. The major difference is that the internal unit is installed in the ceiling. This unit then disperses air out through ducts in various rooms. The major advantage of this is the ability to heat/cool an entire house.

The technology also allows you to zone the areas to be heated/cooled. These systems however can be difficult to install in already built houses – get in touch to see if this will suit you.
