Frequently Asked Questions

What size AC for 2 rooms?

For two separate rooms, you typically need two individually sized split AC units rather than one unit shared across both. Standard Indian bedrooms of 120–200 sft are well-served by a 1.4–1.5 Ton inverter unit each. Sizing depends on room area, sun exposure, occupancy, and insulation, so measure each room separately before choosing capacity.
