Very BAD review. It's NOT meant for a large room like that. You need to spend more money and install a bigger AC. This machine is meant for caravans, camper vans, tents, van life etc. For a MAX of 7 meters. And works perfect for this!
We did say it work ok in a smaller room. But it was loud. We got this for or motorhome. Not our caravan/ lodge. Over all we were not that impressed with it. Thanks for the comment.
