After extensively researching recommended wall unit ACs, we decided to purchase 2 of these to replace our old units in our bedrooms. Our previous wall sleeve dimensions were 27x17, and even though we did not use the Impecca wall sleeve, the AC units still fit snugly with the foam padding provided in the packaging. The installation was easy, and within 20-30 minutes, it effectively cooled our 100 sq ft bedroom from 101 degrees to 70. One of the remotes initially didn't work, but was easily fixed with a new battery. The unit is relatively quiet on low mode. Additionally, the shipping was fast, arriving a few days earlier than expected.

This item is great for controlling humidity.
