Choosing the correct air conditioning size is essential for comfort and efficiency.
A unit that is too small will struggle to cool the space, while a system that is too large may cycle too frequently and waste energy.
Basic Room Size Guide

| Open plan area | 5 kW + |
Factors That Affect Air Conditioning Size
Several variables influence the correct system size:
- room size and ceiling height
- insulation levels
- number of windows
- sun exposure
- number of occupants
- equipment generating heat
Why Professional Design Matters
Professional installers calculate cooling loads to ensure systems operate efficiently and provide consistent comfort.
