Room Size and Capacity

The size and capacity of an Air Conditioning Unit being installed depends on the size of the room it is heating or cooling. The larger the room, the larger an air conditioning unit will have to be.

  • Undersized Air Conditioning Units will have to work harder therefore not energy efficient.
  • Oversized Air Conditioning Units are a drain on energy and expensive to run.
Room Size and Capacity
  • Office: 125 watts (0.125kW) per square metre, a 30m² Office should require 3.75kW
  • Retail: 140 watts (0.140kW) per square metre, a 100m² Office should require 14kW
