    Dual-Hose Unit Cools Area Fast


    We tried at least 6 portable units in our home last summer, with the intent of returning them right away if they didn't do the job. Unfortunately we were too late with one return, so now we're stuck with a single-hose unit doing nothing in a room upstairs. Last but far from least is this Whynter dual-hose job! It starts cooling the room down within minutes. We have it in the living room, and our hot guests cool off the minute they walk in. All the other indoor units we tried were single-hose and required some sort of attention re: water residue…how to get rid of it! This unit, the moisture goes out with one of the hoses; we have NO problem with water in the house, no pans needed, no draining hose needed. It's wonderful! I'm pleased enough with this unit that I want to get one for upstairs. Most importantly, though, is the cooling power it has. And it has it! It topped all other units we brought into the house. Also an important note: my electric bill went up very, very little. Granted, we don't use this everyday, but during the summer we paid no more than $20 more per month. Perhaps it is because ALL the fans get turned off and we run only this unit for cooling. Again, we're talking maybe running it 8ish hours a day--sometimes less, sometimes more. We never leave it on when we leave the house. We also turn it off at bedtime. Sorry I can't tell you much about installation. We have a thick-cardboard makeshift for the 8-inch opening in our sliding door entry, but will change it to a wood panel when we have time to spend on it. I'm completely satisfied with this product, and highly recommend it to anyone. Trust me, the dual hose makes ALL the difference! Don't waste time and energy on the single hose. It's a pity they don't make more of the dual.

    Doesn't seem to be a good brand.

    This was my 4th attempt at a Whynter portable AC. After trying their 12k BTU AC/10k BTU heater 3 times only to receive 3 faulty models (vent wouldn't stay open) I decided to try this model. It never cooled as well as my 10 year old LG of the same BTU's it kinda worked. Wouldn't recommend using dual hoses unless your unit is very close to the window. If the unit is any farther it seems to be choked for air. That being said the far left side of the vent doesn't push air out, making the air go out straight and right only. Cooling power itself is underwhelming. Room is roughly 225 square feet and it struggled to keep the room cool with just a couple heat sources on (TV, computer, ps4). 1 star product in my opinion, but with all the trouble I had whynter's customer service people were friendly and helpful, so 2 stars overall.

    Disappointed for the price

    After carefully reading the pros and cons of many different PAC's. I choose this one because it seemed the most bang for the buck. But after having it for over a month I ended up returning it because of poor craftsmenship and it didn't perform as advertised. The unit was louder than what was expected and leaked which I didn't notice until I went to return it. I was checking the filter and noticed that a good portion of the fins facing me on the radiator were crushed. I don't know why this unit was not rejected during the QC process at the factory. Because this unit is no longer sold on Best Buys website, I am now having to spend a hundred dollars more to get an equivalent PAC. I was willing to exchange the unit out because it basically did its job and give it the benefit of the doubt that the next unit would not be damaged and I really didn't want to spend more than I had too.

    Excellent Performance


    This is my second Portable A/C purchase, and by far the best. The double hose feature provides superior cooling, and the upper condensate drain port, which fits a standard garden hose fitting, provides the ability to constantly drain into a separate container is a blessing. I had a couple of problems/questions which were promptly and capably dealt with by Whynter customer support. The exhaust/intake hose, and window kit installation were not as easy as the instructions would lead you to believe, maybe because we are both senior citizens. That would be my only criticism.

    Very easy setup/ dual hose system matters

    • My Best Buy® MemberMember

    Very easy to set up I dont have any double hung windows in my family room so i had to construct a new setup for my casement window with some plexi glass,the room is approm. 15 x 20 and this unit cools it relatively well , i did put an upright fan in front to help with the cooling, really not as noisy as I thought it would be , make sure you do buy a dual hose system ,makes a very big difference

    Bad QC.


    We bought three of these. One leaks and needs to be emptied every thirty minutes. One won’t run on any outlet without blowing a fuse. The last one actually works, but won’t get the small bedroom that it’s in below 70, despite being on alllllll day and night. Not happy.

    Works well but was't for me

    I bought this for my mom whose swamp cooling was't cooling off her bedroom but unfortunately it was too strong for her electric sockets. It kept shorting out the electricity through the whole house which is not a big place so I do not recommend this for a bedroom alone. Better suited for a living room area or bigger space

    The portable AC unit works like a charm. After I added a 20amp dedicated line it works even better! Easy to set up the window exhaust system is a bit flimsy, but works need to use some tape and insulation to make a better seal.
