▸2.0000 tons of refrigeration (RT)
- 2.00 RT sits in the residential range. Most central home AC systems run between 1.5 and 5 tons.
- That equals 24,000 BTU/hr or 7.034 kW of heat-removal capacity.
- A rough HVAC rule of thumb: 20 BTU/hr per square foot. At this capacity that covers roughly 1,200 sq ft (actual sizing depends on climate, insulation, and occupancy).
- Refrigeration tons measure heat-removal rate, not electrical consumption. An HVAC unit rated at 1 RT does not necessarily draw 1.17 kW of electricity - actual power draw depends on the system's COP (coefficient of performance).
Next stepFor full HVAC sizing, consult ACCA Manual J which accounts for climate zone, building envelope, window area, and occupancy - a rough BTU rule of thumb can be off by 20-30%.
