AC Size & BTU Calculator
Calculate the ideal AC tonnage (BTU) for your room based on dimensions, sun exposure, and occupants for Indian summers.
Quick Summary: AC Size & BTU Calculator
Choosing the right AC tonnage prevents 'Over-cooling energy waste' or 'Under-cooling compressor stress'. For a 150 sq.ft room in India, 1.5 Ton is standard, but if it's west-facing with thin insulation, you may need a 2 Ton Inverter unit for 2026 climate extremes.
