Really good for a room that has no ventilation and gets hot, it's a little loud but when using headphones blocks out the sound, gets really cold

I have split system aircon in my other rooms of the house but needed something for my office so I thought why not try this out I am very impressed it cools the room very fast and I see people saying the portable air con is so noisy I didn't find it to be at all. I have a split system running for most of the time and this is only a little louder. Highly recommended.
