Air Conditioner Tonnage Calculator
The Air Conditioner Tonnage Calculator is a practical online tool designed to help users determine the correct AC capacity needed for cooling a specific space. Selecting the right tonnage is essential for comfort, energy efficiency, and long-term cost savings.
AC tonnage refers to the cooling capacity of an air conditioner. If the tonnage is too low, the room will remain hot and uncomfortable. If it is too high, it will waste electricity and reduce humidity control efficiency.
This calculator ensures you choose the perfect balance based on room size, insulation, sunlight, and occupancy.
What Is AC Tonnage?
AC tonnage represents the amount of heat an air conditioner can remove in one hour.
- 1 Ton AC = 12,000 BTU/hour
- Higher tonnage = more cooling capacity
How the Calculator Works
The tool estimates required cooling capacity using:
Core Logic:
Cooling Load (BTU) = Room Area × BTU per sq ft (20–60 range)
Then:
AC Tonnage = Total BTU ÷ 12,000
Factors Considered
The calculator adjusts based on:
- Room size (length × width)
- Ceiling height
- Sunlight exposure
- Number of people
- Electrical appliances
- Insulation quality
How to Use the Tool
- Enter room dimensions
- Select ceiling height
- Choose sunlight level (low, medium, high)
- Enter number of occupants
- Add appliance load (optional)
- Click calculate
- View recommended AC tonnage
Practical Example
Room size: 14 ft × 16 ft = 224 sq ft
Base calculation:
224 × 25 = 5,600 BTU
Adjust for heat load:
≈ 7,200 BTU
Final recommendation:
7,200 ÷ 12,000 = 0.6 Ton AC
Rounded suggestion: 0.75 Ton AC
