Split Air Conditioners are the most cost effective way to cool separate areas within a house. Perfect for apartments, town houses, offices and frequently used living areas. Split ac system units vary in size from single 2kW units to Fujitsu Multi head split systems up to 14kW with 9 internal heads. Using inverter technology the Fujitsu split ac units may only consume 10% of their available electricity capacity once the room is at the desired temperature.
