We had to modify our window in order to use this as our windows slide left to right. This unit cools the ambient temperature of the room very quickly and very well. We are able to run it on eco mode with auto fan so it can determine what it needs to do I order to properly cool our room. The room is at least 500sqft in size and in 113* weather this unit is able to cool the room to 70 and maintain that temperature all day. It is also very quiet while running

I purchased this to provide additional cooling to an upstairs bedroom that runs much warmer in the hot summer months. The pros: The cooling capabiliity and quietness of the unit is great. The installation is fairly easy but you will need 2 people because of the weight, one person needs to hold the unit while the other person makes the fit adjustments. I like that it’s energy star rated. I am hopeful my electric bill will go down significantly because my HVAC will no longer need to run at a lower than usual temperature for hours at night to cool the upstairs bedroom. I’m most excited about that. The cons: The side panels are a bad design and did not fit flush against the side window tracks. You will need to use the weather strip and provided putty to fill quite a few gaps. I am very particular about energy efficiency and bugs getting into my home so I also sealed off any open spaces and gaps with white duct tape. (It’s not very pretty but it does the trick and the window curtains hide the sides). The remote is also a pain because of the extremely tiny screw that needs a special tiny screwdriver to remove. It’s totally unnecessary because the battery cover will secure without the screw. Good luck getting it out and I wouldn’t put it back in. The unit motor makes a few weird noises but according to the manual they are normal and it’s still quiet enough to sleep. The app is pretty good and has a few more features so I would recommend downloading it. I feel this air conditioner will serve the purposes for which it was intended nicely. Despite the few cons, I think it’s worth the money and I’m confident will pay for itself in the long run.

Our AC arrived with some damage due to shipping (not the seller’s fault), but they responded quickly and professionally. After we provided photos of the damaged box and unit, they promptly sent us a brand new replacement. No hassle, no need to return the damaged one, and no extra expense on our end. We haven’t set up the WiFi features yet, but the unit itself is extremely quiet and works beautifully. We’re very happy with both the product and the customer service. Highly recommend!

Here is where I'm at until things are resolved. This unit delivered with damage on the back of the unit which twisted the frame and the plastic grill on the front is broken. Integration with Google Home is terrible. You can only turn the unit On/Off and adjust Fan Speed. Noise level of the inverter compressor is a bit loud at slower speeds. I'm not sure if this is due to the damage of the chassis. Besides that the unit would be very very quiet! Overall size is bigger than I thought it was going to be for an 8,000btu unit. It's sized similar to a 10,000btu unit that is not an inverter. Weight is the same story. Just be aware of that. I do not like the accordion sides they use on this unit. It's 3 plastic pieces that move in and out instead of the typical pleated accordion style you see on any other AC out there. They don't seal the sides as nicely. Cooling ability at the moment is very good. The air is very cold and time will tell. I will adjust my review when the seller makes things right.

We have a summer behind us using this A/C in the loft in our cabin. The size cools the loft fine and the cool air drops into our main living area. A nice benefit.

Got this unit on sale and couldnt be happier with the value. I easily installed this in my studio in Hollywood just in time for summer and didn't feel a thing. The fit of the AC was a bit tight but I prefer that to help with insulation. I put it in my kitchen window and it's pretty far removed from my main living space. Usually, this would mean that it's internal thermostat will shut it off before the main living space is the right temperature. However, I linked this AC to my Amazon Echo Dot in my main living space. This means that my dot can control the AC based on its own internal thermostat and have it work more precisely. Also, the AC is incredibly quiet, especially in it's mute mode. All of its out of the box options are clearly legible and easy to use. Phenomenal!

Amazing piece of technology. It is so quiet, I have bought a 2nd unit for another floor of the house. It definitely handles much more than 20x30 cooling with ease... My prior units are 15+ years old and I had not realized how great technology has gotten sincce then It lost a star for the bizarre WiFi device connection procedure. They should study how Govee does Wifi. The most annoying is that it can only talk to my 2G network. You have to switch networks during the connection procedure, click the Display button on the remote 6 times, and other weird stuff. I also had to manually select my device type. Again, Govee does it better. Last but not least, I had to use a Jewellers screwdriver to open the remote to put in the batteries. If I did not have one of these, I would have had to run out and buy these screwdrivers which are smaller than even the ones for opening a laptop. At least they should have included a screwdriver.

We installed this AC unit in July and ran it pretty much nonstop until the end of September and it worked wonderfully. It kept a 400sqft room very cool. The install was super easy and we had no issues. I feel it was a great value for a 12000 btu ac unit, would definitely purchase another one if needed.
