A highly effective and budget-friendly cooling sol
[This review was collected as part of a promotion.] The Keystone 12000-BTU Window AC is a **strong budget contender** for cooling medium-sized rooms. Its core strength is delivering powerful, effective cooling at an attractive price, enhanced by the convenience of a remote control. However, it comes with the expected trade-offs: noticeable compressor noise (especially o...

Amazing air conditioner, easy to install
[This review was collected as part of a promotion.] I’ve been using this Keystone unit for a few weeks now in my 1-bedroom apartment (about 500 sq. ft.), and I’m honestly amazed. It cools the whole space within 10–15 minutes, even during hot afternoons. It’s surprisingly quiet on the low setting, and I can sleep with it on without any issues. The remote makes life easie...

Finally! Cool and quiet!
[This review was collected as part of a promotion.] I had to jump on here and write a review for this Keystone 8000 BTU window air conditioner because, honestly, it's been a game-changer for us. Our old AC unit was truly on its last legs – sounded like a rusty lawnmower fighting a losing battle, rattled the window constantly, and barely managed to cool the room even a f...

Perfect energy-efficient AC unit for our outdoor b
[This review was collected as part of a promotion.] This Keystone AC is a perfect fit for our outdoor storage/workshop building space. We do wood working projects in the building and it gets really hot in the summertime where we live. We experience high temps along with high levels of humidity, and this Keystone AC unit was especially needed to keep our outdoor buildi...

Quiet, Quick, easy installation and cools my 500 s
[This review was collected as part of a promotion.] I have a 500sq ft bedroom. This Keystone comfortably cools the space. I was leery after seeing some reviews saying this unit is rather noisy - it is not, in my opinion.
Easy install - kit was included and the instructions were clear. Love the remote control and the washable filter options! I would recommend this unit!

Powerful cooling for large spaces
[This review was collected as part of a promotion.] I received this air conditioner for free from Influenster in exchange for my honest review, and I’ve been genuinely impressed. The Keystone 12,000 BTU window unit is a powerhouse. It easily cools my large space (about 500+ sq ft) quickly and efficiently. Even on the few warm days we’ve had the room stays comfortable wi...

The design make it super easy to set up on your window.
My favorite modes are FlashCool mode that kicks the fan into high speed for fast cooling, perfect when you need instant comfort. Sleep mode for quieter nighttime operation, and...

So thankful and excited for summer with this!
[This review was collected as part of a promotion.] I was unable to take a photo of it installed as it actually began snowing here lol! But we tested and tried it in our living area window. We have an open concept home and the downstairs and after letting it run for only 20ish minutes the entire downstairs room it was installed in was significantly cooler. It was so qui...
