Maximum Coverage with Different Heat Loads
An mobile air conditioner’s cooling capacity depends on factors like heat load levels. High heat loads demand greater cooling power or reduce your unit’s effective coverage.
Approximate room sizes in square metres (m²)
| BTU Rating | Low Heat Load Coverage | High Heat Load Coverage |
|---|
| 9,000 BTU | 20-25 m² (215-270 ft²) | 12-16 m² (130-170 ft²) |
| 12,000 BTU | 30-35 m² (320-375 ft²) | 18-22 m² (195-235 ft²) |
| 18,000 BTU | 50-55 m² (540-590 ft²) | 30-35 m² (320-375 ft²) |
Low Heat Load: Well-insulated rooms, minimal sun exposure, few occupants/electronics
High Heat Load: Poor insulation, south-facing windows, high occupancy, or hot climates
Always consult specific product specs – ceiling height, layout & sunlight affect performance
