When we returned from vacation our old 24,000 wall AC had finally died and we had 2 weeks of 90 degree weather forecasted. We want to get a ductless split system installed but knew it would be awhile before we could get someone to do it so we had to get something temporary to cover a large open area which included our kitchen, dining and living rooms. This little 6,000btu unit did almost as well as our 24,000 btu unit, it has been a lifesaver for the last few weeks!
