Please do not buy this product. It is wrongly mentioned as copper but the condenser is actually aluminum.The seller is not willing to admit his mistake.Worst ac. I had to shed 13000/- to get this crap repaired in less than three years! This is for our bedroom and it is excellent. It maintains the set temperature and is quiet. The bad feature for the bedroom is the timer. We set it for a time to turn off a couple of hours after we go to bed and it works very bad to keep us cool and to have it run all night.Would not recommend this line of air conditioner. I had 3 installed in my house. One of them works ok, the other 2 click all the time. I've had servicemen out to repair, they can't seem to find the fault. Avoid at all costs. Wish I had gone with another brand. 9pkr and 24pk
