Replacement

Unit packaged well and received without any damage. I had an old unit that went bad and this was a replacement. We pretty much just swapped them out since bracket holes were already drilled so we just put new hardware on and slide unit in place. Working well since.

Fantastic

[This review was collected as part of a promotion.] This has been absolutely love changing! I have had a portable ac unit in our bedroom since our sc broke about 2 years ago and we have kept it to aid with the house system since it gets so dang hot in Florida! This unit absolutely exceeds my expectations tho! It keeps my entire upstairs much cooler and I know it is giving my whole house ac unit a huge break since I like in 2 stories! I couldn't be happier with this!

Honestly the best air conditioner unit i have ever

[This review was collected as part of a promotion.] I was so excited when I was chosen to receive this new keystone slider window air conditioner unit, it's really a nice unit, quiet, installation was easy comes with all the hardware, bracket support to prevent the unit from falling or becoming unlevaled , keeps my entire 2 bedroom home cool and comfortable, has a remote making it easy to adjust temperature from the comforts of my couch . The digital display shows the temperature at all times. Very happy and impressed with this unit
