A 1 ton AC is right for a middle-floor room of up to about 130 sq ft — a typical 10 × 12 ft bedroom, a study or a kids' room. On a top floor with afternoon sun, keep it to about 95 sq ft, or step up to 1.5 ton.
Buying 1 ton for a room that needs it is not a compromise. An oversized AC reaches the set temperature before it has removed the moisture, leaving a room that feels cold and clammy, and it costs more to buy. The right size runs longer, dehumidifies properly and uses less power.
Check rated watts, not just the tonnage in the name. A true 1 ton is 3,517 W, 1.5 ton is 5,275 W and 2 ton is 7,034 W, and several units sold in each class are rated 5-12% below that. Every product here publishes its rated cooling where the brand does, and our room-size advice is calculated from it.
1 ton AC prices: compare the installed specification
For a 1 ton air conditioner, compare rated cooling capacity, the energy-label validity period, ISEER and installation requirements. Match the complete indoor/outdoor model pair when comparing Daikin, LG, Samsung, Voltas, Blue Star, Lloyd or another range. A matching tonnage label alone does not establish equivalent performance or features.
