BTU Guide
BTU is a capacity figure, not a room-size shortcut.
The BTU figure helps describe an air conditioner's cooling capacity. A higher BTU number does not automatically make a unit the better choice; the capacity should suit the room conditions.
Common domestic capacity steps
- 9,000 BTU
- 12,000 BTU
- 18,000 BTU
- 24,000 BTU
Why the room still matters
Two rooms with the same floor area can need different capacity because ceiling height, glazing, sun exposure, insulation, roof exposure, room use and occupancy can change the heat load.
How to choose between the sizes
Use the Click-Aircon Size Calculator as a starting point. The calculated result is rounded up to the next supported standard capacity so the recommendation does not round down below the indicative load.
Product availability, specifications and warranty conditions are model-specific. Check the actual product information supplied before ordering.
