    • powerful but not designed for a window
Style: Heat/Cool 230V Color: Bright White Size: 10000 BTU
This is a decent wall mounted A/C unit. It is easy to install in an existing space, otherwise it may be difficult. It can be modified for a window opening, but is not designed for it. It has a bunch of functions that are easy to use on both the unit and the remote. It puts out a ton of cold air, and is not too loud considering the type of unit and size. ... show more

    • Didn’t cool from Day 1. We’re returning it on Day 2.
Style: Heat/Cool 230V Color: Bright White Size: 12000 BTU
ZERO ability to cool, and that’s for a brand new unit right out of the box. After a pretty easy installation for this through-the-wall unit, it turned on, remote and fan worked fine. But cool air never came out, even after several hours. The reassuring, low bass sound of a working compressor that normally precedes a refreshing blast of cold air was ne’er to be heard! To address this, we turned to the troubleshooting tips in the Keystone users manual (only two pages out of thirty). Sure enough, a listed problem was open “air unit does not feel cold enough.” However, none of the listed correction methods helped: (1) the temperature sensor behind the air filter element could have been touching the cold coil; but we checked, and it wasn’t; (2) setting unit to a lower temperature was also recommended; but when we set it to the minimum of 62° F the room temperature of 80°+ did not fall a single degree over several hours; and, (3) the compressor could have stopped while changing modes and we were asked to wait three minutes after setting to the COOL mode; but we let it run for hours after shifting to cool, yet no cooling ever arrived. Spending an weekend with three overnight guests was uncomfortable as you might imagine. Let’s just say we’re not the happiest of buyers right now. Upon calling Amazon, we learned that for our particular situation, replacement was not possible, but refund was. Consequently, we’ve removed this defective Keystone unit from its sleeve, box it, and are now awaiting UPS arrival to rid of its being! Thankfully, there will not be a delivery charge for the return. That’s quite good because the unit weighs about 80 pounds. Dropping it off at a UPS store would have been pretty difficult. We are replacing it with 14,000 BTU Frigidaire through-the-wall unit which actually cost less and weighs only 50 pounds, making installation even easier. (The previous Frigidaire, which we tried to replace with the Keystone had stopped working nine years after its manufacture in 2015.) This experience made us realize that maybe nine years is a pretty good life for ACs, which seem to have more variability than one might expect. Will be happy to get another nine years out of the new Frigidaire we are ordering. Wish us luck! ... show more

    • Strong but noisy and old technology
Style: Heat/Cool 230V Color: Bright White Size: 10000 BTU
"It possesses excellent quality and functions very well in a one-bedroom apartment. However, the major drawback is its reliance on outdated technology and lack of smartphone connectivity. It would greatly enhance convenience if an app were added for smartphone control, along with an increase in panel size. While the remote's range is acceptable and it functions reliably and robustly, it does produce a slightly noisy operation." ... show more

    • Excellent quality in wall air conditioner!
Style: Heat/Cool 230V Color: Bright White Size: 10000 BTU
This is an absolutely awesome and high quality in-wall air conditioner in my opinion! It did take a fair amount of time to install in the wall and get the proper electrical power to the unit, but the effort was definitely worth it for sure! It does a great job of cooling the room, and I really like that I can use the included remote control to make changes to the settings. I also like that it is capable of three fan speeds, and the unit also has a built in dehumidification system which is huge plus too. In addition, I like the timer and sleep modes. Only time will tell the longevity and durability of the unit, but so far I am very happy with this product's performance. With that being said, I highly recommend it with the top five star ranking and recommendation all the way! ... show more
