  • worked on horizontal sliding windows too
Style: 10,000 BTU
I was able to install it on my window despite it being horizontal. I just needed to cover the window opening with plexiglass. The AC supports are strong enough to hold it in place even without the window on top of it. However, either my walls are too thin or the gap is too big, so I had to add some pieces of wood. ... show more

  • Works good and doesn't block the window like other units
Style: 12,000 BTU
We were a bit leery about purchasing this air conditioner due to there not being a lot of reviews yet and all the reviews seemed to from people who received this item free. Overall, I am so happy we purchased it! It's quiet and cooled the room right down. Installation was easy but took two people. We had to add some boards between the house and the screws to hold it in place because they weren't long enough but it's no big deal. The only thing I don't like is the water plug is on the part inside the house. Haven't used it very long yet but so far it seems worth the money and I absolutely love that we can still see out our window. ... show more

  • Low profile inside and out.
Style: 12,000 BTU
Excellent product! It's a 2-person job to install but worth the effort. The room cooled down quickly. It comes with the insulation too so we didn't have to stuff the windows with anything else. Hardest part was adjusting the screws for the outside of the unit to secure it in place. Once installed, no openings for little critters to get in. ... show more

  • Great design...hoping dents does NOT affect performance.
Style: 12,000 BTU
This arrived in a decent looking box, but there was some denting of the unit. Had to be done before shipping in box. So far it seems to work ok...watching for issues. A little disappointed and hoping it will be fine. The design is perfect for our needs...so easy to install.

  • Faulty Unit Vibrates Intensely
Style: 10,000 BTU Upgraded
The media could not be loaded. I installed this and loved the model. It looks great and the option to still open my window and the unobstructed view is fantastic. However, after running it for about 10 minutes it started to vibrate intensely, so much so that the whole wall started to shake. We jokingly called it the earthquake function. It had been sitting right side up for over 24 hours prior to installation, but I let it rest some more thinking it might need more time for the refrigerant to settle. Nothing, didn’t work, it again started shaking very soon after turning it on. Sadly, I have to return this unit that I really wanted to work out. It’s really very nice, but something is very wrong with the unit I received. Hopefully, it’s a fluke. ... show more

  • Best design ever for window AC
Style: 12,000 BTU Upgraded
Easy to install, I had our electrician put in a dedicated line, but he said it might not have been needed since it only pulls 6 amps.
