When buying an AC in India the most important question that many consumers have in mind is how much ton AC should they buy and whether the AC will be sufficiently enough keep the room cool. If you ask this question to the salesman most probably they will try to sell you the maximum ton AC, which in fact will be more than required to cool the room.
So how does one calculate how much ton AC a room requires?
The answer is very simple. To find the ton AC required you should know the length, breadth and the height of the room. Once you have the figure (in feet) just multiply all of the three to get a total.
So the formula goes Total = Length (feet) x Breadth (feet) x Height (feet)
Now compare the total that you have arrived according to this chart.
| Total | Ton AC Required |
| Less than 729 | 0.75 |
| Between 729 and 810 | 0.75 |
| 900 | 0.75 to 1 |
| 1000 | 1 |
| 1089 | 1 |
| 1210 | 1 to 1.5 |
| 1296 | 1 to 1.5 |
| 1440 | 1.5 |
| 1690 | 1.5 |
| 1960 | 1.5 to 2 |
| 2250 | 2 |
There are several other factors that you also need to consider for effective AC cooling.
- The number of Windows in the room.
- Application that produce heat such as TV, Desktop etc.
- If the room gets too much sunlight.
Once you know the total you can easily find the Ton AC required for your room.

Our room is 30x33x9 on Ist floor of 7 storey building. It’s has good ventilation with opposite side windows. We’ve been using 1.5 ton since last 20 years but I feel 2.0 ton would be better. Thinking of Hitachi. Kindly suggest. Thanks

In simple words it packs a bigger engine.
Just like your car/bike , the bigger the engine the more the power/pickup/top speed.
But efficiency is another parameter which will be calculated by the ISEER rating.
For a room little bigger than a double bed 1 Ton is sufficient , but if you are using it in your lavish master bedroom you will need to go anything equal or above 1.5 Ton.
For a 280 sq feet room my AC does the job , considering that it is a bedroom and always closed when the AC is on and secondly we don’t reside on the top floor where the AC has to work really hard to cool the walls continuously heated by sun.
Just by my experience i have a Voltas 1.5 Ton 5 Star Split AC Aluminium, 185JY, http://amzn.to/2qxXmCQ ,its quite sufficient for my requirements.

While asking for tonnage define your location because heat load is mainly depends on location. In India you can take 1tr/120sq.ft. (for commercial). And it is different for different sectors.
