FFRE1233S1 is rated 4.4 out of 5 by 399.
Rated 5 out of 5 by from Works Wonderfully & Is So Quiet! We bought this air conditioner two months ago and it has worked exceptionally well since we've installed it. It cools down the room quickly and is quiet. This works so well, we bought a second unit.

Rated 5 out of 5 by from works good for the office it is in. It was good but I had to fix the "screw adjuster" as it was not fully connected when I opened the box.

Rated 1 out of 5 by from Do not buy My 85 year old mother bought this last Sept 14, 2017 and used it one month last year and 2 months this year and the control panel froze up on it. The only way to turn on or off is to unplug it. Its stuck on 69 degrees on high speed fan. Called Frigidaire and they won't send anyone out to fix it. They are mailing paperwork and she has to fill it out and mail back. Could take over 30 days to hear back. Terrible way to do business for seniors

Rated 5 out of 5 by from weight, price and features are great I purcahsed this unit to replace an old one of 20 years. I live in a 1500 sq. ft. one level house. It keeps our house comfortable with the aid of a 2nd 12000 btu unit. This unit is easy to operate and installation was quite simple. I am considering purchasing a second identical unit to replace our 2nd 20 yr. old one. So far very pleased with this unit. I only hope it lasts at least half as long as our other one. I really like all the features of this unit..

Rated 4 out of 5 by from Does the job I bought this product to use in a small studio apartment. My main concern was that I buy a unit powerful enough to cool down the entire apartment in a short amount of time, and to keep it cool throughout. I'm glad that I went with a 12k btu unit. The apartment cools down in about 10 mins. The only thing that I wish was was different is the placement of the air vents. Since my apartment is small, I had to place my bed right next to the window. Since the vents are front facing, the air blows directly on me all night, even if I try change the direction of fan blades. I've seen some units that have the air vents placed on top of the unit, so the air flow is directed towards the ceiling. Other than that the unit is great.

Rated 1 out of 5 by from A.C. didn't work from the start The AC unit I received did not blow cool air at all from day one. I received it June 20th, 2018. Since I got it from a third party online at Wal-Mart, I have been getting the run around about the return. I still have the piece of junk in my house almost a month later. I went with this brand based off of a friend who highly recommended this brand. I will never order another product from Frigidaire or ever recommend it to someone. What a nightmare this whole ordeal has been.
