HVAC Tonnage Formula:
| From: | To: |
HVAC tonnage refers to the cooling capacity of an air conditioning system. One ton of cooling equals 12,000 BTU (British Thermal Units) per hour. It represents the amount of heat required to melt one ton of ice in 24 hours.
The calculator uses the HVAC tonnage formula:
Where:
Explanation: This simple calculation converts BTU measurements to standard HVAC tonnage units used by manufacturers and contractors.
Details: Correctly sizing an HVAC system is crucial for energy efficiency, comfort, and system longevity. An undersized unit will struggle to cool your space, while an oversized unit will short-cycle, reducing efficiency and failing to properly dehumidify.
Tips: Enter the total BTU capacity of your HVAC system. The calculator will convert it to standard tonnage measurement used in the HVAC industry.
Q1: What's the relationship between BTU and tonnage?
A: One ton of cooling capacity equals 12,000 BTU per hour. This measurement originated from the amount of heat needed to melt one ton of ice in 24 hours.
Q2: What size HVAC system do I need for my home?
A: Typical residential systems range from 1.5 to 5 tons. The right size depends on square footage, insulation, climate, and other factors. A professional load calculation is recommended.
Q3: Can I use this for both heating and cooling systems?
A: This calculator is specifically for cooling capacity. Heating systems are typically measured differently, though some heat pumps may use similar measurements.
Q4: What if my system is measured in SEER or other ratings?
A: SEER (Seasonal Energy Efficiency Ratio) measures efficiency, not capacity. You'll need the BTU rating to calculate tonnage.
Q5: Why is proper HVAC sizing important?
A: Proper sizing ensures energy efficiency, optimal comfort, adequate dehumidification, and extends the life of your HVAC equipment.
