AC received on time. Installation guy noticed damaged copper pipes. Immediately called Amazon Customer Service. First, they said we don't refund money in account, we will give you gift vouchers. I right away said no and asked them for refund of damaged material. After talking to them for 30 mins approx. there senior approved the refund which I got after 15 days that too after regular follow-ups. Now, lets come at this Air Conditioner. I am using this AC for past 15 days. AC doesn't cool much. Even after 2 hrs, you don't feel the chill in cooling. Temperature just doesn't reach cutoff limit which I had kept at 25 C. Very normal cooling which even 1.5T AC was giving me earlier. I won't recommend this AC. Instead go for Bluestar or Llyod.
