❓ How do I calculate what tonnage AC is needed for my room or factory?

You can use our online Room AC Tonnage Sizer calculator right on this website! In general, for Pune climate: 100-120 sq.ft requires 1.0 Ton; 130-180 sq.ft requires 1.5 Ton; and 190-250 sq.ft requires 2.0 Ton (with additional adjustments for top floor sun exposure).
