A window unit would work better, and takes up less floor space.
21 July 2013
Summary: I got this unit to temporarily cool a windowless space that is equivalent to an 800 sq ft area. It only reduces the temperature by about 10 degrees after running an hour, and the room never cools to 72 degrees. If it ran all the time, it might be able to cool the space. It will probably cool 300 sq ft adequately on a hot day, and it would make a 400 sq ft bedroom comfortable at night.
May not be the best for humid locations unless you disconnect the pump

Summary: All in all I have to say I am satisfied with this AC. I read many reviews and decided to go with this unit. We are waiting to replace our broken central AC unit with a high-efficiency unit, but we have a lot of attic work to do before this happens. In the meantime, I bought this portable unit to hold us off during the hot Florida summer months. With it being 91 degrees AND humid in the house was desperate.
Summary: Comments about Soleus Air LX-140: The product itself is not very good. It leaks quite a bit and isn't very cold. The worst part is the rude and slow customer support from the manufacturer. I'm surprised they can stay in business.
Summary: I bought this unit for a heating unit in my wifes art studio but had to buy a furnace to do the job. The room is 20 x 30 and well insulated but the unit would not do the job. I will use the unit for air cond. in the summer months. I do wished the unit would have worked but just too small . I do hope it will cool the room as of yet not tried it ( been too cold here ). I like the portable of the unit , it will store in the closet till summer. It is easy to operate.
