Quite and cools fast

[This review was collected as part of a promotion.] I've been using this mini split for a little while now and so far I really like it. It's very quite and cools the room down pretty fast. I was surprised by how quickly the room felt comfortable after turning it on. Its been running smoothly and i'm so happy with it

The unit that does it all
on September 29, 2026

[This review was collected as part of a promotion.] This incredible unit is a game changer in home heating and cooling. We installed this in our garage/shop unit and it works like a dream. Installation was tricky and you absolutely must hire a professional to so. Once installed, the unit is easy and intuitive to use and the features are endless. Whether you are a “set it and forget it” style of user or someone who really likes to tweak and customize, this is the unit for you. The indoor profile is slim and sleek as well so you barely notice it. But you certainly notice how well it heats and cools. Its also built like a tank and we foresee this being in use for a long time with no problems.
(I am unable to upload photos right now but will try and come back and do so later)

It’s a great mini split for the price, and I’m very satisfied with the performance. I would definitely recommend it to anyone looking for a reliable 9,000 BTU mini split.

[This review was collected as part of a promotion.] Im very happy with the Keystone 9,000 BTU mini split. The 115V standard setup was easy to work with, and the unit has been cooling the space quickly and efficiently. The indoor unit runs quietly, and the outdoor unit has been working smoothly without any issues. The temperature control is great, and it keeps the room comfortable even on hot days. I also like the clean, simple design of the indoor unit

Great unit

[This review was collected as part of a promotion.] This is one of the best split units I’ve ever used. Goes all the way up to 88 degrees to keep the area warm and down to 61 to keep it cool. Quickly switched between the two temperatures with no hassle and changed the temperature in the room just as fast. Easy installation did not take long to complete. Strong airflow that you can feel in the room. Remote control is easy to use as well
