Before starting writing review, I would like to tell you few things like how to calculate tonnage requirement for an Air conditioner. All you need to know how much big your room is?
So, just find out your room floor area like(10 ft x 10ft= 100 ft2)
Divide it by 600. So, this gives you basic AC capacity. And you have to add 0.5 ton for every 5 people.
So, its like 100 divided by 600= 0.167. Add 0.5 ton for 4-5 people living in that room which results as(0.167+ 0.5)= 0.667.
So, for 10ft x 10 ft room, usually a 0.8 ton air conditioner is enough.
Same way you can calculate tonnage require of air conditioner for any room size.
Also to mention, always go for a rotary compressor, your electricity bill would be 15-20% lower and noise would be low and cooling efficiency would be much better.
