There was a problem filtering reviews right now. Please try again later.
I already had a sleeve, this fits perfectly,w/ a tad bit of space to spare, & i used some foam supplied in generous amount btw., to fill in the space. The snap-together 4 piece frame finished off the look. Also came w/ a rear guard, which i took off the old rusty junky one, from about 25+ years & it easily screws in w/ 2-4 screws.
The packing & everything was in mint condition. (i’ve tons of diff sized pieces of soft and hard foam pieces left over) i just put them away for rainy day purposes/uses.
Now..as far as the operation: It works brilliantly. Cools very nicely. Easy to use. Plenty of features. Remote is great! This unit has a timer function, sleep function, & the ‘follow me’ feature on the remote is a nice touch, when u press it, it’ll display the temp on the remote(in cool mode only) of the location of the remote/which obviously is mostly always in the same room! The remote has a nice orange backlit led display. Energy Save function works great! The overall sound is not too bad, more/less like most large in wall sleeve units. I’m not exactly a ‘decible numbers expert’ but, I’m not bothered by a/c noise.
So....Compared to my utter NIGHTMARE experience from 2016-2019 w/ THREE diff Frigidaires in a row!! I am SERIOUS. 1 after the other, starting w. the first replacement in 2016 of the original a/c that was in my condo when i moved in 15 years ago. Within just over a year give or take, they-each one, would slowly start malfunctioning, & totally take a nose dive. And even springing for the extra warranty, that too was a COMPLETE NIGHTMARE. I was not about to buy a 4th one from my local Mom/Pop appliance place, who never had a straight answer, nor offered real assistance, just took my $$$, and they only sold that one lone brand-Frigidaire.. LESSON LEARNED the hard way!!
The Keystone brand off the bat works like a dream, not just in contrast to my bad experience w/ Frigid., but i really love this a/c & it’s many great features and functions.
I posted about 6 pics, including the front/back of the 6-15 plug, hope that helps.
For me the price was right also- for a 12,000 btu, @$595-delivered to my door. As opposed to upwards of $700-$800 or more for 12K btu & larger ones, in stores. Best of luck & stay cool, healthy & safe!

This unit seems to work great, effortlessly switches between A/C and HEAT in AUTO mode. Fairly certain the thermostat is inside the remote itself which provides better climate specific to the user's position / location in the room. Overall, I'd say its worth the money, just understand that it could be damaged upon arrival. I knew that going in so I wasn't shocked. Also, if you're installing it by yourself, you'll probably need a hand as its a bit heavy... unless you install these all the time, in which case you probably have a few tricks and a strong back. In my case, we had to lift it up 6ft to install in the wall.
Oh yeah, this one has a standard grounded 110V plug. Any grounded outlet will do. My situation has it matched to a 20A breaker so everything's good. Guessing a 15A breaker without other devices connected would work just as well. Hope this one lasts a while. The previous Kenmore unit kept going for nearly 20 years. Guess I'd be lucky to have this one last 10 years with the way things go these days. Overall quality is good. Nice controller. I'm happy overall, aside from the broken corners, of course.

The unit is quiet, clean, reliable and very effective for us. The "dry" cycle works quite well as here in Cleveland we frequently have hot and humid weeks - setting the temp at 70-72 and in dry mode has kept the humidity down and temp comfy.
I would recommend having help installing the unit. It isn't that heavy or awkward but should be considered a two person job especially if your through wall sleeve is mounted as many are, at 5'.
Highly recommended!

Works fantastic and looks very modern, plus nice to have the Auto thermostat on the remote.
Would have given 5 Star but there was a small crack in the housing from shipment.
Hopefully things continue to work great for the LONG TERM.
