AC Ton Size Formula:
| From: | To: |
The AC ton size calculation determines the appropriate air conditioning capacity needed for a space based on BTU (British Thermal Unit) requirements. One ton of cooling equals 12,000 BTU per hour.
The calculator uses the simple formula:
Where:
Explanation: This formula converts BTU requirements to standard AC tonnage, which is the common measurement used in the HVAC industry for residential and commercial air conditioning systems.
Details: Proper AC sizing is crucial for energy efficiency, comfort, and system longevity. An undersized unit will struggle to cool the space, while an oversized unit will short-cycle, leading to humidity problems and reduced efficiency.
Tips: Enter the total BTU requirement for your space. The calculator will convert it to the equivalent tonnage. Ensure accurate BTU calculations based on room size, insulation, windows, and climate conditions.
Q1: How many square feet does one ton of cooling cover?
A: Generally, one ton covers 400-600 square feet, but this varies based on climate, insulation, ceiling height, and other factors.
Q2: What's the difference between BTU and tons?
A: BTU measures cooling capacity per hour, while tons are a standardized unit where 1 ton = 12,000 BTU/h.
Q3: Can I use this for commercial AC systems?
A: Yes, the formula works for both residential and commercial systems, though commercial systems often use larger units.
Q4: What factors affect BTU requirements?
A: Room size, insulation quality, number of windows, ceiling height, climate zone, and heat-generating appliances all affect BTU needs.
Q5: Should I round up when sizing my AC unit?
A: It's generally recommended to choose the next available size if your calculation falls between standard unit sizes, but consult with an HVAC professional for precise sizing.
