We bought our Keystone through the wall airconditioner a month ago, it has cooled our place over some of the hottest days of the summer, the fan is not loud and allows us to keep it running while watching tv. It was very easy to install.
We are very please overall, would recommend this product.

Efficient upgrade for us

Bought this a month ago after our old through the wall ac gave up. This new ac was the same size but way more features, higher btus, energy saver feature, and has heat. It came with complete accs such as foam strips, back protective grills, etc. 

Btw, for installation, i hired an electrician which im glad i did. The manufacturers of these brand was so concerned about the customers safety that the had a built-in breaker w/ led light on the 240v 20amp plug (different plug from 240v 15amp). So he had to re-route our outlet from hidden inside the wall to the frontside (and upgrading our outlet at the same time). So if the power fluctuates, the built in breaker will trip to protect the sc unit and your home, all i have to do is press the button on the plug to reset without having to remove the whole ac to access the plug. But if your ac outlet is located on the front, then you have nothing to change.

Great product, bang for the buck.

Great a/c for the price.

The AC we had no longer cooled and was 30 + years old. We found this one at Sam.s after looking all over ,for 240 volt units ( other stores and on line , only could find was 110 volt window units ) The unit fit right in the wall box like it was made for it !

We are all COOL NOW !!

Good AC

the a/c compressor doesn't turn on. It's brand new out of the box.

Keystone 14,000 btu through the wall a/c and heat.

Perfect replacement for our 25 yr old AC unit. More powerful and heats as well. Good energy rating. Time will tell how long this will last.

Solid so far

[This review was collected as part of a promotion.] The unit did not work. It only blew out room temperature air after being installed by an AC and refrigeration professional.

Disappointed

[This review was collected as part of a promotion.] Unit came with everything to complete the installation. Measurements were accurate as opening had to be reduced slightly.  Unit works well and air movement noise is acceptable.

Just made it

[This review was collected as part of a promotion.] This air conditioner sucks! It will not even cool the 10'x 14' room below 78 degrees. I want a refund and will return it!

Not a air conditioner

[This review was collected as part of a promotion.] it was easy to install. runs great and is pretty quiet. love the remote control.
