  • A GREAT air conditioner !
This is a GREAT air conditioner. Got it installed and turned it on. It was very quiet and was throwing out VERY cold air ! Set the temp at 72 and went back downstairs for a few hours. My wife went upstairs and said it was freezing up there !! Turned the temp up a bit, and noticed that it had cooled my ENTIRE UPSTAIRS. This is a very nice machine and I give it 5 Stars. I would buy it again. Also, it comes with a very nice remote control. It is easy to install and well worth the money. Don't be afraid to buy this one !! ... show more

  • Not very good
down to 1 star because the unit can produce cold air and isn't too loud. Problems with smell and AC controls. Changes temperature by itself for no reason. I put it on 66 so it won't stink, and it changes the temperature on its own to 72 then switches to fan and starts producing a mold smell. Second update: The remote is fairly unresponsive, takes it a few seconds to register command to the unit. Also when I push power on, unit does not remember the last command and resets at 72F. The problem with 72F is it often is on fan only so the bad smell comes in. I manually pushed it to go down in temperature and the physical buttons on the AC did not work, so I had to use the remote to change the temperature down. Update: One problem I'm having is around 72-76F temperature settings the unit smells bad, musky. Since the unit is new and no smells are in my room or outside, I'm assuming it's because of water not evaporated or something like that. I read some units are using more aluminum instead of copper which can allow more bacteria. Either way I'm not sure, but new out of the box the unit at higher temperatures produces bad smells. Pros: This unit is not too loud, I've tried a Midea unit and the Midea is quiet, and this unit is quiet or maybe slightly louder but has a quiet mode that is probably around 40db give or take. I've also tried the standard $150 small window unit and it is very loud so I put it in an area where the volume doesn't matter. Cons: The screws you extend on the outside for support are a bit on the flimsy side relative to the weight of the unit. I'm setting some weight on top of the inside portion in order to balance it out a bit and keep the screws from almost bending from the weight. A picky thing that doesn't really matter: unit does not seem to come with a piece of insulation to shove in the top window crack. Information: So my window only opens to about 13" or so. I have a fold out style window, so I really went nuts and disassembled part of the window in order to get this unit in. So by taking out the bottom glass, and taking out the screens, I was able to get like a 13.5" opening which just barely fit this unit through. So just be aware that if you have a smaller window and might try to fold the U shaped unit through, it can be tricky and you can't get much extra space even utilizing the saddle shape. Might be able to do it from the outside, I'm not sure. I had to just straight shot it through from the inside. ... show more

  • Works well so far.
I have used this AC daily for 3 weeks and I am very pleased with it. The unit arrived several days early. I did need someone to help remove it from the box but decided to do the install solo ( two people would definitely make it easier.) I let it sit upright 24 hours before unboxing and install and if worked great out of the box. Currently using it in a garage and it is a game changer there. The design is a very low profile instead of taking up half of the window. One caution - be sure your window measurements are accurate. The airflow is good but I put a small fan on top to help distribute the air since the room is big. It has multiple settings including a quiet mode and energy saver. The built in dehumidifier is definitely a huge plus in keeping the area comfortable. Only unknown at this point is durability and what the electric bill increase will be. I would buy it again. ... show more

  • Overall great buy
Cools well and installation is super quick. Highly recommend 2 people to lower the unit onto the sill, but otherwise just a 5-10 minute task. No additional tools or assembly needed. While not overly loud, it does have a vibration noise that the Medea unit I have does not. Also, the fan blows all the time even when the desired temperature has been reached. Overall, great buy. ... show more

  • The right ac for hot Georgia summers
The media could not be loaded. So, I just put in the Antarctic Star U-Shaped Air Conditioner, and honestly, it was way easier than I thought. The U-shape is pretty smart because I can close my window almost all the way, which makes it feel solid and keeps the cool air in. The installation kit had everything I needed, and the instructions were super easy to follow. Once it was set up, I was kinda blown away by how quiet it is. Even on high, it’s barely making any noise, so I can chill, sleep, or watch TV without any annoying sounds. It cools the room fast and spreads the cool air evenly, which is awesome with this crazy heat. What’s really cool is that it’s energy-efficient, so my electric bill didn’t shoot up like it did with my old AC. It also looks pretty sleek and doesn’t make my window look all bulky or messy. Plus, I can control it from my phone and tweak the temperature whenever I want. All in all, this thing’s a win—easy to install, super quiet, and saves energy. Totally happy with it! ... show more

  • Don't buy it
Started off great at the beginning of the summer in June. Kept my house cool and crisp. The cooling ability has progressively become almost non existent. We are now in September and it's only 82° outside and it is struggling to get the inside temp down to 78°. We have provided regular cleaning and maintenance all summer. We also had problems with it randomly changing the set temp. We would set it at 70 or 72 and it would change itself to 75. The fan seems to struggle occasionally now, where it worked great for the first 1.5 months. I don't recommend this air conditioner. It was a waste of money. ... show more

  • Quality
Works great, we bought two 12500 BTU units, U shaped units very easy install, we shipped them down to Guyana South America, because we couldn’t find any thing with quality like these units, we needed to have AC in two bedrooms because it’s hot down in the desert, we bought them because they use very little amp draw of electricity, our rooms are 14X30 and they cooled so well we we had to turn down the temperature, very great product ... show more

  • Good, but feel a bit cheated.
Arrived dented in two spots even though I bought it brand new. Works to cool a fairly good sized space and isn’t super loud. (Wouldn’t consider it whisper quiet either).
