AC Tonnage Formula:
| From: | To: |
The AC tonnage calculation converts British Thermal Units (BTU) per hour to tons of refrigeration, which is a standard measurement for air conditioning capacity. One ton of refrigeration equals 12,000 BTU/h.
The calculator uses the simple formula:
Where:
Explanation: This formula provides a straightforward conversion from BTU/h to tons, which is essential for proper AC system sizing.
Details: Proper AC sizing is particularly important in Florida's hot and humid climate. An undersized unit will struggle to cool effectively, while an oversized unit will short cycle, leading to poor humidity control and reduced efficiency.
Tips: Enter the BTU/h rating of your AC unit. The calculator will instantly convert it to tons of refrigeration. This helps in verifying proper AC sizing for your Florida home.
Q1: Why is AC tonnage important in Florida?
A: Florida's hot, humid climate requires properly sized AC systems for effective cooling and humidity control. Incorrect sizing leads to comfort issues and higher energy bills.
Q2: What's the relationship between BTU and tons?
A: One ton of cooling capacity equals 12,000 BTU per hour. This measurement originated from the cooling effect of one ton of ice melting over 24 hours.
Q3: How many BTUs do I need per square foot in Florida?
A: In Florida's climate, a general rule is 20-25 BTU per square foot, but this can vary based on insulation, windows, and other factors.
Q4: What are common AC tonnage sizes for Florida homes?
A: Common residential AC units in Florida range from 1.5 to 5 tons, with average homes typically requiring 2-4 tons depending on size and construction.
Q5: Can I use this calculation for heat pumps too?
A: Yes, the same tonnage calculation applies to heat pumps in cooling mode, as they use the same refrigeration cycle as AC units.
