AC Tonnage Formula:
| From: | To: |
AC tonnage calculation determines the appropriate air conditioning capacity needed for a space based on its square footage. One ton of cooling equals 12,000 BTU per hour, which can cool approximately 600 square feet of space.
The calculator uses the standard formula:
Where:
Explanation: This formula provides a general estimate of AC tonnage requirements based on standard industry calculations for residential spaces.
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, reducing efficiency and failing to properly dehumidify.
Tips: Enter the total square footage of the area to be cooled. For accurate results, measure each room's length and width, then sum the areas. Consider factors like ceiling height, insulation, window exposure, and climate which may affect the calculation.
Q1: What is a "ton" in AC measurement?
A: One ton of cooling equals 12,000 BTU per hour, which is the amount of heat needed to melt one ton of ice in 24 hours.
Q2: Is this calculation accurate for all situations?
A: This provides a general estimate. Actual requirements may vary based on insulation, ceiling height, window size, climate, and other factors.
Q3: What if I have high ceilings?
A: For ceilings higher than 8 feet, increase the square footage by 10-20% to account for the additional volume.
Q4: Should I round up or down when choosing AC size?
A: It's generally better to round up to the nearest half-ton for better performance, but consult with an HVAC professional for specific recommendations.
Q5: What other factors affect AC sizing?
A: Insulation quality, number of windows, sun exposure, number of occupants, and heat-generating appliances all impact cooling requirements.
