This is a decent wall mounted A/C unit. It is easy to install in an existing space, otherwise it may be difficult. It can be modified for a window opening, but is not designed for it. It has a bunch of functions that are easy to use on both the unit and the remote. It puts out a ton of cold air, and is not too loud considering the type of unit and size.

The unit works well, but it is the loudest air conditioner I’ve ever used. It’s deafening. I would have liked to return it, but it’s been installed already.

I recently purchased this and I’m impressed with its performance. The combination of heating, cooling, and dehumidifying functions makes it a versatile choice.
One standout feature is its quiet operation, ensuring a peaceful environment. The sleek design in bright white adds a modern touch to any room. The included remote control enhances convenience, allowing easy temperature adjustments from across the room.
Installation was straightforward, and the wall-mounted design saves valuable floor space. The 10,000 BTU power efficiently cools or heats the room, and the dehumidifier function is a bonus for maintaining optimal humidity levels.
Overall, the Keystone High Efficiency Wall Mounted Air Conditioner & Heater is a reliable and efficient choice for year-round comfort. I highly recommend it for anyone seeking a compact, powerful, and versatile HVAC solution.

Keystone is a new brand for me and doesn’t have much of a history to really let me know what sort of longevity I can expect from it. I thought it was worth giving a chance at the discount price over the more common brands. The unit is average in size but performance is excellent for the price and the unit operates quietly. The primary function is definitely cooling but this unit can also supply heat so long as the outside temperature is near freezing or warmer. As temperatures cross below freezing, the unit becomes less efficient. The unit features a remote control which works well.

I installed this in a 2 car garage to cool, dehumidify and heat when working on projects in the garage. It’s a little noisy but that is not really an issue for me in the garage. You have to buy a sleeve separately for the install if you are not replacing an existing unit. The Keystone version is about $100.

My mom currently lives in a rent stabilized apartment complex and during the year, her apartment can get either too hot or too cold depending on the month. I have been on the lookout for a unit to replace her current in-wall air conditioner and stumbled across this one that popped up in my feed.
The unit itself is amazing. It provides everything she needs in one convenient product. on the warmer days, she can turn on the air conditioning portion of the unit, and it is a monster. It makes the entire apartment nice and cool since this particular unit can boost out ten thousand BTU’s. In the cooler months, she can turn on the heat function that this unit also has which I have not seen in an air conditioner before. The heat comes out perfectly and everything can be adjusted to her preference. Comes with a handy remote and LCD screen which is easy enough for her to see and use. This unit was a perfect choice for her apartment.

This is an absolutely awesome and high quality in-wall air conditioner in my opinion! It did take a fair amount of time to install in the wall and get the proper electrical power to the unit, but the effort was definitely worth it for sure! It does a great job of cooling the room, and I really like that I can use the included remote control to make changes to the settings. I also like that it is capable of three fan speeds, and the unit also has a built in dehumidification system which is huge plus too. In addition, I like the timer and sleep modes. Only time will tell the longevity and durability of the unit, but so far I am very happy with this product’s performance. With that being said, I highly recommend it with the top five star ranking and recommendation all the way!
