frequently asked questions

What is Ducted Air Conditioning?
Ducted systems are designed to centrally heat and cool a large number of rooms or an entire home. They can be suitable if you have an open-plan house, and/or prefer heating and cooling in all or most rooms of your house simultaneously. Ducted systems consist of:
  • the heat pump itself, located outside or in the roof space
  • ducting, usually installed above the ceiling to distribute the conditioned air throughout the home
  • vents, attached to the ceiling or walls (or sometimes the floor), directing the conditioned air into each room
  • a return air vent (grille), to recirculate air back to the system for reheating.
What does Reverse Cycle mean?
Reverse cycle air conditioning is the most energy efficient method of heating or cooling your home. It means that the air conditioning system can cool in summer and heat in winter.
What does Inverter mean?
An air conditioner bearing the inverter tag uses a variable-frequency drive to control the speed of the motor and thus the compressor.
What is a Split System?
Split systems are permanently mounted systems with the compressor unit located externally and a separate condenser inside the home. These are joined together by piping, which carries the refrigerant. The remote location of the compressor makes these units significantly quieter than window/wall models. The internal unit of a split system is most commonly installed on a wall. However, units which can be located at floor level (which gives optimum heating performance), on the ceiling surface, or in the ceiling as a cassette are also available. Wall units must generally be installed on an external wall to provide adequate draining of condensate.
What is a Multi Split System?
Multi-split systems are split systems with more than one internal unit connected to an external compressor. Systems with between two to five internal units are available, and are able to heat multiple rooms independently.
What is Zoning?
Zoning means dividing the house into separately controlled areas. Each Zone can be switched on or off as the need arises, e.g. Day Zone (Living Areas) and Night Zone (Bedrooms).
