Amazing for small rooms, horrible for large rooms

This is a box version of the Midea U. It's blistering cold and has a powerful fan. The fan uses 20 to 40 watts, you'll feel it blowing 20 foot away. At the top end the AC will use 1360 watts. At the low end it'll use 200, 450 and 680 watts then ramp up and down to 900 and 1360 watts. For a small room maybe 350sq ft this ac is amazing. For a mid to large room this ac is garbage. Let me explain. Im trying to cool a living room + a kitchen + a spare bedroom. The total footage comes out to 580sq ft. The living room and kitchen are 430 sq ft and the spare room is 150 sq foot. This midea will jump up to 1360watts and cool everything down to about 76 degrees . Blizzard like cold air, strong airflow and it took the rooms from 95 degrees down to 76 in about an hour. This is where the problem starts. Once the ac hits your desired temp (76) the ac will just ramp down to 240watts. the cold Blizzard turns into a warm gust. The Midea will spend the rest of the time hopping between 250, 450, 680 and 900 watts trying to maintain your desired temp. Unfortunately with a large room this means that the area around the window will be the desired Temps but the area or rooms that are farther away from the window ac will start to warm up. What ended up happening is that my living room would hover around 77/79 degrees my kitchen around 80/82 and my spare bedroom around 84/86 degrees. If the Midea would blow full blast this wouldn't happen,but it won't because it's trying to save energy. I decided to return this midea and get a traditional AC that blow full blast all the time. I left this midea unused for 2 days and then emptied out the water in the ac. There's no drain hole so I had to flip it over to drain out the water. When I did this I noticed there was condensation in the inside fan in the front. The Midea U is known for having a mold problem because they have no drain hole and because of the lid that opens/closes the front fan will have condensation and grow mold. Look up midea U mold issue in youtube and you'll see what I mean. These box midea inverter will have the same issues because there's no drain plug in the back. In order to rectify this you'll have to keep the fan running for an hour after you turn off the inverter to dry off the fan from condensation. I don't want to babysit a window ac so I decided to return it. I have no regrets returning this midea inverter. I purchased a 12k btu midea traditional window ac. It flips between 2 states, 1360 watts full blast artic blizzard mode and 180 watts when the fan is only running. Now everything in my 580sq ft living space is a nice 78 degrees. I would recommend this ac for rooms no larger than 400sq ft. You'll also want to buy a box fan because when this inverter ramps down you won't feel a thing from the ac.

AWESOME!

Bought one for garage last year, love it. Just bought 2 more. Not sure if I'm allowed to mention price, but this unit is the best price and is currently on sale, grab em before they run out till next season... and due to the political climate, I suspect they will be out of reach.

THE BEST window AC you can buy

This thing CRANKS super cold air so quietly. Installation could not be easier. The only downside is the app is no longer supported and for me I couldn't connect to the device but I can't imagine there's anything else on the market this good for this price. We also have one of the U-shaped units from Midea and love that one as well. 100% recommended, I would buy these forever or until I buy a house with central AC.

Full of mold after 3 months.

This is the worst, lowest quality air conditioner I have ever owned. Only 3 months old and already full of mold. The water cannot drain correctly, even with the plug removed from the back. It is mounted at the proper angle for water to drain but it does not. The inside front of the unit where the filter goes is full of mold, only some of which can even be reached. And it's impossible to even clean the visible mold without bending the fins on the lower part of the evaporator. The reason this is so cheap is because it can only be used for a year or two, after that you will be breathing in mold that can't be reached or cleaned. Do not buy from this company, they already have other units under recall/return because of mold. They don't know what they are doing, or how to design an air conditioner.

Unit unable to cool room

Got 3 of these, installed them correctly but one of the units is unable to cool the room and woke me up around 1 am with a high pitch sound. Restarted the unit. Waited about 10 minutes, but still not cooling enough. Read the manual, and even when set on the lowest setting (60) air is not coming cool enough to cool the room. Maybe I got a defective unit, taking it back for an exchange/ return.

Awesome unit

I've been using it for a few weeks now and it's worth it! It's really quiet compared several other widow units I've tried. It gets really cold...not cool, cold!! I use it in my outdoor enclosed 12 x 14 ft gazebo. Even in 80+ heat it keeps it COLD. I don't have to turn up the TV or stereo volume when its running like before.
