If you are after a unit that will both, heat and cool the entire house however will mainly be using it on its cooling mode, then we advise a Ducted Split System. These units are the ‘bigger brother’ to the wall hung split system yet are hidden away inside your roof cavity.

Ducted Split System provides discreet air conditioned and heating comfort throughout your entire home. The ducted system can be installed in a new home or tailored to suit an existing one, and once installed, only the controller, the return air and discharge grilles are visible inside your home.

Ducted Air Conditioners consist of an indoor and outdoor unit and flexible ducting. The indoor unit is concealed out of sight, in your ceiling or under the floor, with flexible ducting distributing conditioned air through vents located throughout your home. An outdoor unit is positioned in a discreet location outside your home.

Much the same way a split system works the ducted split system is composed of two units, one unit is located in the roof cavity and the other is located outside. Ductwork is neatly installed out of sight inside the roof and vents are installed in each room. In cooling mode, the warm passes over a coil, is cooled and distributed through the ductwork into each room. Heat is absorbed into the coil and sent to the outdoor unit by means of refrigerant pipework. This process provides cool, comfortable conditions inside the house even in the hottest of days.
