Great Product
This Keystone air conditioner works great. My husband uses it in his office. It was easy to set up. It's good quality and not noisy. It comes with a remote which is nice. There's also heater mode which works well but haven't used it since it's summer but will come in handy during cooler weather.

Need an outlet adapter
Luckily, the size of the window AC actually fits. It’s compacted and easy to install. However, my issue is the plug in is not compatible to the standard US outlet. We are not able to actually use it yet until we get an adapter.

This is heavy make sure you have a second person a
Easy to install as it is already assembled. It does not make a difference in energy consumption so your power bill won’t change just a few cents however I used this in the summer and not in the winter so the heat could possibly cost more energy. Its not super loud just a little bit louder than a normal fan. This is a 220 v if you don’t have a 220 outlet do not buy this.

Performance
Best window A/C I ve ever used and since we live in texas in the winter the Heat pump option works great. The limit of ourside temps needing to be above 41 is no problem at all. In the last the lowest recorded temp in texas where we live has only been lower than 41 for 1 day in the last seven years.

It's so great and works so amazing!
Installation was so easy, and it took less than 10 minutes! Seems to be very quiet as well. i can hardly tell it's running unless im in the same room. it's on in. It works so well and cools my entire 900 square foot house! Even on the 89-degree day we just had! I love being able to set the temp, and when it reaches it, it turns off! It's such an amazing unit!

Easy to setup.
This a/c unit was a snap to get installed. It did take two of us, just to take pressure off the window ledge.
I ended up putting it in my office about 5ft from my desk. Customers comment how quiet it is, and ask me where to get one. I love that it has a remote. My other ones have not came with one. I am thinking about getting a few more units for the office.

Works great
I received this influencer promotion to give an honest review about the product. My room has no windows, so I had to put the air conditioning on the wall. This air can be used in windows or walls. The installation was not easy, but it was achieved. This air conditioning helps a lot to cool the bedroom. Since the sun gives direct and with the HVAC, it is not enough to...
