assignment Calculation Details
For top floors or rooms with direct sunlight on the roof, it's generally recommended to increase your calculated capacity by 10-15% to compensate for the additional thermal load.

Understanding Air Conditioning Capacity
Choosing the right air conditioner size is crucial for energy efficiency and comfort. A unit that is too small will struggle to cool the room, while an oversized unit will cycle on and off too frequently, failing to dehumidify the air properly.

How We Calculate AC Tonnage
Our calculator takes into account multiple environmental and structural variables to provide the most accurate recommendation for your specific cooling needs.
Key Factors for AC Capacity
- Room Dimensions: The total cubic volume of the space determines the baseline BTU requirement.
- Occupancy: Human bodies generate heat, requiring roughly 600 additional BTUs per person.
- Sunlight Exposure: Heavily shaded rooms require 10% less capacity, while sunny rooms need 10% more.
- Climate & Temperature: Regional high temperatures impact the peak cooling requirement.
Recommended Tonnage by Room Size
| Room Size (Sq Ft) | Recommended Capacity (Tons) |
|---|---|
| Up to 120 sq ft | 1.0 Ton |
| 121 to 180 sq ft | 1.5 Tons |
| 181 to 240 sq ft | 2.0 Tons |
| 241 to 300 sq ft | 2.5 Tons |
