Room Size to Tonnage Guide
Indian conditions require more tonnage than standard formulas suggest.
180–200 sq ft
Large master bedroom, medium living room
Standard 2-ton is ideal
200–250 sq ft
Large living room, dining + living combo
2-ton with convertible mode recommended
250–300 sq ft
Open-plan living + dining, large hall
Consider 2.5-ton or two 1.5-ton units
300–400 sq ft
Large hall, combined living + dining + kitchen
Two 1.5-ton units often more efficient
Why Indian Rooms Need More Tonnage
High Ambient Temperature
Indian summers regularly hit 42–48°C. Standard formulas assume 35°C ambient — underestimating load by 20–30%.
Poor Insulation
Most Indian homes lack proper wall and roof insulation. Heat gain through walls and ceilings adds 15–25% to the cooling load.
Large Windows
South and west-facing windows in Indian homes create significant solar heat gain, especially in the afternoon.

Pro tip: Run the LG AC at 26°C with the Atomberg BLDC fan — the fan's wind-chill effect makes 26°C feel like 24°C, cutting your bill by ~30% vs running AC alone at 24°C.
