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 tonnage of AC required for your room.

Your air conditioner isn't consuming freon coolant (gas), so under ideal conditions, the freon would never need to be filled or changed. But you could have an HVAC tech check for a leakage properly (especially with older models). It should be included in your PM service.
