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.

2. suggest me size(ton) of ac for both room? kindly.. thnx in advance

Fit 1.5 ton blue star in 11*16*10.25 room and fit 2 ton ac for 16*16*10.25 room as 1.5 ton is not enough for bigger room.

Hi,
we live in Bangalore My room volume comes to 1287 with approx 198 covered with wood work. might add a LED TV in future. There is one floor above us and there is no direct sun exposure, will be used between March to June months, so not looking for a great energy saving. Ideal temp maintained should be 22 to 24. Should we go for 1 ton or 1.5 ton?
Sathish
1 ton is sufficient
