    • A little noisy, need to buy a sleeve for it
Style: Heat/Cool 230V Color: Bright White Size: 10000 BTU
I installed this in a 2 car garage to cool, dehumidify and heat when working on projects in the garage. It's a little noisy but that is not really an issue for me in the garage. You have to buy a sleeve separately for the install if you are not replacing an existing unit. The Keystone version is about $100. ... 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

    • 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

    • Unit Did Not Work---never cooled!
Style: Heat/Cool 230V Color: Bright White Size: 14000 BTU
It never cooled air at all. NOT FOR A MOMENT! The condenser never came on. Like some other reviewers, the fan and the remote control worked just fine. What an ordeal partly because my family installed the unit while I was on travel and they left the packing materials out in the rain. I had to find a box that would handle the return. Also, as others have commented, Keystone customer service was pretty much non-existent.....was advised that there weren't any techs dedicated to customer technical problems. I wouldn't ever be tempted by a Keystone product. Amazon should rethink carrying their products. ... show more

    • Wouldn't recommend for a bedroom
Style: Cool Only 115V Color: Bright White Size: 8000 BTU
I'll admit that I'm a little bitter because the install instructions were horrendous and the customer service department has zero technical know-how, but beyond that, I'm super disappointed in this unit. It is so loud, even on it's lowest setting. And the controls are not even slightly intuitive which is a bummer. Should've shelled out a little more money for a better product >=( ... show more
