                I had a 5000 BTU AC unit that struggled on above 85 degrees F. Ai suggested this one I'm in very glad it did! This one handles the heat, is very much quieter! Also, I can turn it on from at work and walk into a cold place! It fit my window perfectly and was easier to install and had less areas to seal!
                by
                Our central air conditioning broke in the middle of a heat wave, as is typical it seems. I was looking for a window AC unit that did NOT have wifi as I abhor home smart devices and do not need every single electronic device in my home connecting to the internet. On all websites I looked at, this 10,000 BTU unit was listed as not having wifi, plus it had an inverter, so I purchased it. Lo and behold, it DOES have wifi and the listings are all incorrect. You can actually see the wifi button in the pictures for the unit so I felt kind of stupid to have missed it. I think the listings are not correct because they use the same information for multiple Keystone units and do not update them properly based on the actual unit you are looking at. The good news is that it does not seem to constantly put out wifi or bluetooth signals unless you choose to push the button, which will matter to those to whom it matters. It does have an app which I have not bothered to try as it is not needed for my uses. The unit itself does a good job cooling and works well. We probably should have picked a larger unit for the room size because it does run constantly, but it is meeting our needs. Keystone does seem to be a cheaper brand, the quality feels lower than others and there was a small raised bump on one side that was not on the other side that seems to be from manufacturing. I believe they are made in Thailand. The manual covers multiple units and they basically tell you to figure out which of the features described in it applies to the actual unit you purchased. The information in the manual is not very detailed and is sparse. Our house only has slider windows, however, we were able to set it up at our kitchen window with a plexiglass panel purchased from a different well known website and with a no drill window AC bracket which fit well enough into the slider window frame of our single story house. This is not a normal installation, so buyer beware, I am not recommending it per se and I would not do it on a 2nd story. But it is working very well for us as a temporary solution until we are able to replace our central AC and may be an option for those with slider windows who need a better solution than a portable AC unit. Final comment: I really wish manufacturers would focus more on building quality products that work well for their purpose and last instead of focusing on adding internet ready features and apps. I don’t need the internet on these things, I need machines that actually do what they’re supposed to do well for a length of time worthy of the cost. Drop the internet and put that time and expense towards quality.

                Great AC unit
                [This review was collected as part of a promotion.] I have installed this cooling unit in an external building. The installation process was straightforward. The unit comes with a remote control, allowing for easy and quick adjustments to the settings. It is designed to cool a room or area up to 350 feet, which is suitable for my requirements. I would appreciate if it had a heating feature, but the unit I have received does not include this feature.

                  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 on high settings), potential for vibration if not installed perfectly, basic build quality on accessories, and a less precise thermostat. If you prioritize raw cooling power and value over whisper-quiet operation and premium features, this Keystone unit is a very good choice.

                    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 easier, and I love the energy saver mode—my electric bill hasn’t spiked at all.
                    by
                      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 few degrees. With the warmer weather starting up, we knew we couldn't face another summer like that. Enter this Keystone unit! First off, the cooling capacity is fantastic. Our living room is right around the 350 sq ft mark this unit is rated for, and the difference is night and day compared to the old one. This Keystone cools the room down quickly and keeps it consistently comfortable, even when it starts to get warmer outside. No more sweating indoors! It's such a relief to finally have an AC that actually works effectively. I was admittedly dreading the installation, remembering past struggles. But getting this Keystone unit set up was surprisingly straightforward. The instructions were clear enough, and it came with the side panels and foam insulation needed to get a decent seal. With a little help (definitely easier with two people!), we had it securely in the window in under an hour. Huge sigh of relief! Now, let's talk noise level, because this might be the biggest improvement. Our old unit was loud. Like, turn-the-TV-volume-way-up loud. This Keystone AC is wonderfully quiet in comparison! Of course, you can hear it running – it's an air conditioner – but it's more of a consistent, low hum that easily fades into the background. We can actually have a normal conversation or watch a movie without being drowned out. It's bliss! Energy efficiency was also a big factor for us. Our old unit was undoubtedly an energy hog. This Keystone model is Energy Star rated, which is great peace of mind. It also has an "Energy Saver" mode that cycles the fan and compressor intelligently, plus a sleep mode and a timer. While I haven't seen the electric bill yet, I feel much better knowing we have a significantly more efficient unit working smarter, not harder. And can we talk about the convenience of the remote control? Oh my goodness! Being able to adjust the temperature, fan speed, or switch modes (cool, fan, energy saver, even dehumidify) right from the couch feels like pure luxury after years of fiddling with buttons on the unit itself. It's simple, responsive, and works perfectly. Overall, replacing our dying air conditioner with this Keystone 8000 BTU model was one of the best decisions we've made for our home comfort. It cools powerfully, runs quietly, seems energy efficient, was reasonably easy to install, and the remote is incredibly convenient. If your old window AC is struggling, I wholeheartedly recommend this Keystone unit. It’s been a truly stellar upgrade!

                        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 building cool and comfy for us. The 8,000 BTU model from Keystone definitely cools a 350 sq ft space, it does a fantastic job of cooling our building which is around 350 sq ft or just a tad larger. It keeps our building truly comfortable for us. Love that it's controlled by remote too, thus giving us the ability to adjust the temperature at any time. It's a super convenient feature of this model. The "energy savings" factor is probably what we love best. The programmable timer allows us to simply set, and have our building "cooled off" before we plan to go inside to start our woodworking tasks. We just open up the door, and the building is automatically cooled down to a 'welcomed' comfort level, without us having to wait around for the building to get cool. We also feel that this Keystone AC unit does a great job of removing moisture from the air in our building as well, and that's a big plus for us to eliminate excess moisture. It's a quiet running unit, we don't even notice the sound--we just appreciate and enjoy the "cool comfort" it gives us. So it's definitely not a loud, noise-making model AC. We truly love it. The Keystone unit installation instructions were understandable, easy to follow, and very descriptive which made our overall experience of adding a new AC to our building a positive one. The Keystone brand also provides a 1 year warranty which is also a plus. Overall, we really like the Keystone brand and this model. The unit does a great job of cooling our outdoor building, & we're very pleased with this new addition which allows us to obtain the much-needed cool comfort we crave in the hot summertime.

                          [This review was collected as part of a promotion.] So happy with this new air conditioner!! The installation was so easy, and very fast. Cools extremely quickly also. Remote feature is definitely a must. Highly recommend!

                            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 without feeling overly humid or stuffy. Installation was surprisingly straightforward for a unit of this size, and the included remote makes it incredibly convenient to adjust settings without having to get up. I also appreciate the energy-saving mode and the ability to program a timer—great for overnight use without racking up the electric bill. It runs fairly quietly for a unit this powerful, and the multiple fan speeds and cooling modes give me more control over comfort. Overall, I’d highly recommend this if you’re looking for a high performance window AC that doesn’t disappoint.

                              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 quiet and I cannot wait for summer now to really try this out!
