Have a 100+ yr old hse. Had central air put in last yr. does not cool our upstairs bedroom quite as cool as we hoped. Plus we have two GSD who sleep in the room. It gets hot in there. Saw a review on this on YouTube with OUT OF GOSHEN. They loved it, so I figured I would try it. Easy install. Easy to use. Sounds like a regular window unit so to me it's white noise. Cools the room perfectly. I love this and should have bought it last yr!! The ONLY issue is that the remote control screen does not light up when using it so at 1am if you want to change anything your gonna need a light on. Other than that I have no issues and highly suggest if your on the fence to buy one that you just buy it. You won't be sorry. Just ask my dogs. No more panting or up n down all night looking for a cool spot on the floor lol
