I have a 1500 sq foot shop with 16 ft ceilings and it's amazing how well it will keep the shop at 70 degrees even on a 90 degree day outside. This unit is designed for a normal 700 sq foot area but performs at a much higher level in my opinion.

Not for a 450 sq.ft. Fully insulated metal shop with 14' ceiling in Central Oklahoma. At 78* setting, shop went from 88* and 3 hrs later it was 92*. Returned to Sam's club.

this is a great A/C machine, using in our parts department the old one we had was always tripping our breakers, not this one !!! it also chills more than the 700 sq ft in this 100+ heat this summer and very quiet

Received the air conditioner set it up and waited 24 hours before using. It was located in a 12 x 12 room and after 2 hours had not cooled the room down a single degree it was obviously a faulty unit

Despite its claim I would say this unit could cool, maybe, 100 sg ft. Ours could not cool 350 Sq ft and after a week the compressor gave out and we returned it.

Does the job. Mind the square footage and ceiling height of the room you're trying to cool. This one kept our living room at 72F or below during a central A/C outage that lasted a week.

Lost our MBR 2 Ton A/C and this unit has done a great job of keeping us cool enough to sleep while repairs are coming for our unit. Great to have on hand incase we lose power from a hurricane.

Luckily we only needed this portable ac unit for a week while we waited for a new ac unit for the house, but it worked perfectly. We used it in our master bedroom and vented it out the doggie door. The size was big for the room but least we were cool while sleeping.

We bought this unit to cool our open concept first floor in conjunction with another similar unit. There is 1,000 sq ft on this floor and this unit cools more than it's share with the other unit. We've had this unit for a couple of the hottest weeks this summer and it seems to hold up well. We will see how it is the next few years.

This is a great product, it kept my entire house at 72 degrees when the outside temperature reached as high as 105 degrees. If I wanted it to be cooler at night I put it in my bedroom and shut the door. I also used it to keep my pets comfortable in a closed off room, while other repairs were being made to my house, exterior doors were left open and workers were coming in and out. I originally purchased it because my Airconditioning unit was broken and they said it would be more than a month before repairs could be made. I will keep my unit and be happy to know I have it in reserve for any future events. This would also work great for students in units with no Airconditioning.
