I have installed this one in my apparels showroom and works really fine for me. The service is as good as it can get and are very help full. As far as cooling and sound is concerned compare it with the cold breeze in shimla no more explanations needed for that. the fan mode also works really well and reaches till the end of my 30’ hall. Didn’t had any problems as far as operation is concerned since I bought it six months back. its really a value for money to have but the price shown here is a bit on the higher side as I bought it in 30000/- six months back. May be you can bargain on that if you are notbyuing it online.
