I have only had it in a few days but it’s AMAZING. My “old” AC (only 2 summers old) was driving me bananas. Loud and didn’t seem to cool the space it said it could - (also 8k BTU). As soon as I swapped them I noticed an IMMEDIATE difference. It cools so effectively and barely can tell its on! I got the whisper one since its in my bedroom. I am going to get another one for the second room. Some things are worth splurging for and this is one of them. Get this.
