AC Tonnage Formula:
| From: | To: |
The AC Tonnage calculation estimates the cooling capacity needed for a space based on its square footage. One ton of cooling capacity equals 12,000 BTU per hour, which can cool approximately 400-600 square feet of living space.
The calculator uses the AC Tonnage formula:
Where:
Explanation: This calculation provides a basic estimate of the required cooling capacity based on the size of the area.
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 space to be cooled. For accurate results, measure the actual living area and exclude non-cooled spaces like garages or attics.
Q1: Is this calculation accurate for all climates?
A: This provides a general estimate. Hotter climates may require more capacity, while milder climates may need less. Always consult with an HVAC professional for precise sizing.
Q2: What other factors affect AC sizing?
A: Ceiling height, insulation quality, window size and orientation, number of occupants, and heat-generating appliances all impact cooling requirements.
Q3: What does "tonnage" mean in AC terms?
A: One ton of cooling equals the amount of heat needed to melt one ton of ice in 24 hours, which is equivalent to 12,000 BTU per hour.
Q4: Can I use this for commercial spaces?
A: This calculation is primarily for residential spaces. Commercial buildings have different requirements due to higher occupancy, equipment, and ventilation needs.
Q5: What if my home has multiple floors?
A: Calculate each floor separately and consider a zoned system or multiple units for optimal cooling throughout the home.
