Rated 4.0 out of 5 by 22 reviewers.
Rated 4.0 out of 5.0 by Appealing design with good function Purchase 1 1/2 months ago, so far functioning good. We have casement windows which makes it impossible to have window air conditioner. Since we live in the " mountains" where it hardly gets hot enough to warrant a central air conditioner (except this year been scorcher) this is a good alternative. It cools about 1,000 sq FT to a comfortable 70 F when temperature are in high 80-90's. August 23, 2013
Rated 4.0 out of 5.0 by Works As Designed Purchased a larger BTU unit than needed for the size of the room, which turns out to be a good thing. Unit provides plenty of cooling, but if your room isn't completely enclosed, it will never fully cool the room. I have a second unit in the bedroom, and it cools it off quickly. Ensure you completely seal the window where you install the hoses, as the unit will suck warm air in from the outside. Downsides to this unit is that it is somewhat loud (no louder than a window air conditioner though), and the fan doesn't shut after the compressor turns off. Have had both units for over a year and no problems. September 4, 2015
Rated 5.0 out of 5.0 by this thing actually works It works great cools down the room to around 70 on a 100+ day its held up nicely had a cheaper one from another store and that one broke in a mont n didn't cool right most of the time I recomend this one so far its a great portable a September 4, 2012
Rated 4.0 out of 5.0 by Works well - does the job This unit is attractive (relative to others), blends into our room. It cools a 500 square foot room (which has over 11 foot ceilings) fairly well. Not that noisy and doesn't need to be emptied very often, maybe once a day if running all day. Emptying it is a bit awkward since it needs to be tipped back, but it's doable. The set-up was fairly easy but wish they had longer insert panels to fit our 42 inch windows. July 31, 2012
Rated 5.0 out of 5.0 by Fullfilled all my expectations for the cooling of my office I needed the help of a contractor friend of mine to help me install the window adapter kit since my office is on the fourth floor corner of building. Also required downward facing backdraft preventing vent so nothing can crawl back into unit. Customer service hasn`t been required up to this point and the shipping was excellent. Excellent cooling capacity especially since all windows of my office face the sun directly from sunrise to sunset. The noise level is manageable. Remote control works perfectly. If cooling is your primary concern I highly recomend it. May 20, 2014
Rated 5.0 out of 5.0 by Performs as Advertised I have had the unit about two weeks during what has been an extremely hot summer. Installation went well with no problems. I have in installed in my woodworking shop (read: garage of 425 sqft +/-). I set it to come on about 4 hours before I plan to be in the shop and it is set on 78F. It keeps the shop comfortable enough to work in for extended periods. It has been just what I needed so far. July 27, 2012
Rated 5.0 out of 5.0 by Outstanding A/C This Whynter is a great looking a/c that fits the decor in our office that inexplicably has no central HVAC. Nice digital control panel. Maybe it's just in my head, but the air does feel a lot fresher with the 3M filter in place. I love the fact that it comes with premium filtration and I don't need a separate air purifier. We use it mostly in a 470+ square ft area and have been most pleased with the ambient temperature even in the afternoons. We will likely get a 2 or 3 more units for the rest of the office. Gladly recommend this unit. June 24, 2012
Rated 5.0 out of 5.0 by The product is very quiet and cools great. We use the product to cool our computer room at our office and it does an outstanding job. October 30, 2012
