Rated 4.1 out of 5 by 80 reviewers.
Rated 4.0 out of 5.0 by Good but room for improvement We haven't yet had enough heat to put this unit to the test, but so far it seems well constructed, for the most part. The window attachment is indeed plastic, but it seems sturdier to me than others have reported and it fits either of the windows shown in my photo. I will invest in some insulated weather stripping for the window, however. I agree that the addition of vertical adjustment on the vent of this unit would make sense. It's a curious shortcoming, and I'm wondering if I'll need to place the unit on some pedestal or otherwise direct the airflow upwards to balance the room's air temperature. May 28, 2013
Rated 5.0 out of 5.0 by Great AC Unit I've had this Whynter unit for almost three weeks and I couldn't be happier with its performance. I have a small (650 SF) condo and this unit in conjunction with a strategically placed tower fan has been able to cool down my whole apartment to a comfortable temperature, even during the humid 90 degree days we've been having lately. I've been running the unit in "cool" mode and haven't had to drain it yet - it is definitely living up to its self-evaporating claims. June 29, 2013
Rated 5.0 out of 5.0 by Saving a big bucks I live in Las Vegas and if I use my center a/c, I use 45 kwh per day at 110 degree and only 12 kwh for this one. Of course it only cools down the first floor and kichen and whenever the second floor gets cooler I can go to sleep at night. The drawback is the noise but much betteer than Lg's product. I recommand it if you want to save money. July 16, 2015
Rated 5.0 out of 5.0 by Works great It cools off our bedroom very quickly then we funnel it down the hall with fans to the kids rooms and it works great! July 21, 2015
Rated 4.0 out of 5.0 by Keeps you cool! Recently purchased this A/C. Had some difficulty installing the exhaust hose, kept slipping out of the hose connector in back of the A/C. Other than that it is well-made, runs quietly and keeps the room very cool even in very humid weather . It is also easy to move from room to room. Very happy with this purchase. June 12, 2015
Rated 5.0 out of 5.0 by Great Purchase This Air Conditioner works better than I had hoped. I have only had to keep it on the low setting so far, and my little house stays cool! June 9, 2015
Rated 5.0 out of 5.0 Great purchase easy light weight, but noisy. Noisy because it's a heavy duty cooler, cools room down fast and gets really cold…great purchase and can go into every room the fact its on wheels is so convenient. Works great! July 28, 2015
Rated 4.0 out of 5.0 by Whynter has not disappointed us so far? This is the 2nd Whnyter Aircon I bought and it works well, a 12000 BTU and it cools a 440 sq ft dining room/living room with enough to spare. We turn it to 74 degrees and it's very comfy - can crank it for sure if we want it cooler. One thing - the description online says "no drain hose connection" but it has one for sure. Connect a standard garden hose width (then cut lengh to size) to a small bucket or suitable container as it does drain water from the condensation (we're in San Francisco Bay Area/Peninsula). Funny cuz the 10K btu unit in the bedroom does not drain any water at all. Sound is standard for any portable unit of this type. August 21, 2013
