I bought two of these units a few weeks ago and have used them both a few times since then. So far they both work great and are not as loud as other air conditioners. They were also pretty easy to install and look nice, unlike the old units that came with the apartment and did not properly fit in the wall sleeves. My sister noticed the new units when she came to visit and is planning to buy a couple of them as well to replace the old ones at her house. I’m really satisfied with this purchase overall and highly recommend this air conditioner!
