I am using Voltas from last 3 years at my home. 1.5 ton capacity Voltas have very good compressor so give good cooling. It have a pluses point is that it is consume very low power so good for environment and it is very comfortable and operating is fraindly. It can be adjusted anywhere. So it have very good features. This company provide services as soon as possible. Second think is that on running time no sound. So I am fully satisfied with Voltas company.
