Why floor area alone is not enough

Use the calculator as a starting point and confirm the final selection with an installer.

Key points

Cooling load depends on ceiling height, sun, insulation, people and equipment.

How to use this in practice

Limitations

Outdoor conditions, building leakage, open doors, ongoing sources and furniture layout can materially change performance.
