I purchased this unit a couple of months ago to mount in my 20x20 shop it cooled it right down! I do not even notice any difference in the electric bill. It had many features plus a remote control. I normally keep mine on Econ mode and the unit only runs when it needs too. Easy removal and clean filter. I mounted mine thru the wall as my windows were too small and now can still use them when AC is not needed. Great purchase.
