1. What sort of system should you purchase?
Obviously, the answer to this question will be dictated by your budget. There are basically three types of air conditioning systems applicable to the domestic environment. These Are…
a) A ducted system where all the components are located in the ceiling space with the condenser (outdoor unit) located externally. This is the most efficient, most silent and aesthetically pleasing system available.
b) A wall or floor mounted split system. This system has the fan coil (indoor) unit mounted either on the floor or wall of the room being conditioned. The condenser is located externally. These systems are quiet and efficient however sufficient space is required to install the indoor unit on the wall or floor.
c) A room air conditioner. These units are installed in either a window or wall. As these are one piece units, no interconnecting refrigerant pipes or wires are required.
As with all items, the prices vary according to the degree of installation work required and the performance of the equipment. Hence, the ducted system is more expensive but also the best system with the wall or floor mounted splits less expensive and the room air conditioner the least expensive. The splits system and the room air conditioners are restricted in the capacities available on the market, therefore some larger rooms are unable to be conditioned by one unit.
