Living in a house with an upper floor that practically bakes in the summer sun, a good AC unit isn't a luxury – it's a necessity. After enduring too many sweltering nights, I finally invested in the Midea 12,000 BTU Smart Inverter Window Unit, and let me tell you, it's been an absolute game-changer. This unit lives up to its "smart" name in every way, seamlessly integrating with my Home Assistant setup and providing truly automated comfort. Installation, while a bit more involved than a traditional clunky window unit due to its U-shaped design, was straightforward enough for me to handle. Once in place, the difference was immediate. This Midea unit cools my entire upper floor, roughly 500 sq. ft., with impressive speed and efficiency. What truly sets it apart, though, is its Matter compatibility. Pairing it with Home Assistant was a breeze, and now with my temperature and motion sensors, my upstairs climate control is entirely automated. The unit kicks on only when needed, maintaining a perfect temperature without any manual fiddling. It's truly a set-it-and-forget-it solution. Yes, it comes with a higher price tag than some other window units, but for the advanced features, the incredible energy efficiency, and the unparalleled smart home integration, it's a cost I'd pay again in a heartbeat. The quiet operation is also a huge bonus – no more roaring AC drowning out conversations or TV shows. Pros: * Exceptional Cooling Power: Quickly and effectively cools large spaces (up to 550 sq. ft.). * Unrivaled Smart Home Integration: Matter compatibility makes it a dream for Home Assistant users, allowing for true automation with external sensors. * Whisper-Quiet Operation: Seriously, it's astonishingly quiet, making it perfect for bedrooms or living areas. * Energy Efficient (Inverter Technology): Noticeable savings on the electricity bill compared to traditional units. * Heat and Dehumidifier Functions: A versatile unit for year-round comfort. * Secure U-Shaped Design: Feels far more secure and less precarious than standard window ACs. Cons: * Pricey: Definitely an investment upfront, but worth it for the features. * Installation Can Be a Bit More Involved: While not difficult, the U-shaped design requires a bit more care than just plunking a box in the window. * Occasional App Connectivity Quirks (Minor): While Home Assistant integration is solid, I've had very rare, minor hiccups with the proprietary app itself. This Midea 12,000 BTU Smart Inverter AC unit has transformed my upstairs from a hot zone to a comfortable retreat. If you're looking for a powerful, energy-efficient, and truly smart window AC that integrates seamlessly into your automated home, this is the one to get. It's a premium product, but the comfort and convenience it delivers are priceless.

This is not the top-rated U-shaped Midea model, which is in low supply, one of which I bought in 2023. (So I now have both the U-shaped and the traditionally shaped 12,000 BTU Midea AC window units.) Background: 2 years ago I installed the U-shaped model in the kitchen of our 1910 Sears & Roebuck kit house, a fixer upper, while we lived on just the first floor (600 sqft), and it kept the entire first floor ~72 or cooler (depending on setting) nearly all the time. May have been a day or two it struggled to keep up, but we felt no need for a second unit for the 1st floor. It was SUPER quiet; as quiet as the fridge or ceiling fan, unless cranked up, and most of the sound was the fan. So the U-shaped model was what I wanted for the second floor, but couldn't find it anywhere (within $300 of what I paid before). We finally moved into the second floor bedrooms (last fall), so (mid May) we bought this traditional window box unit (not U-shape), but same capacity hoping to similarly service the 600 sqft second floor. (Yes the second floor was carefully reinsulated during the re-do, and it has efficient vinyl clad windows and thermal blinds. Only about 16' of insulation above ceiling, will see if we need more for summer, but it was fine for winter.) This unit included the heat inverter for heating at temps >41 degrees. It WAS significantly simpler & easier to install than the U-shape as there was no need for an external bracket and bracing, and less complex weather stripping. In retrospect, this model may have been better for the second floor since we could easily do the entire installation from the inside of the house. Took a second pair of hands for the 30 seconds of setting the unit in place in the opening (I'm 71). While this 12,000 BTU unit is perhaps not quite as quiet as the U-shaped 12,000 unit, it is comfortably quiet. We still haven't hit the peak heat of summer, but it seems as though it will keep the entire upstairs sleep-ably cool at night at least so long as the doors are left open. For now it cools fine in the heat of the day up to mid 80's and perhaps more (it hasn't yet exceeded 86 outside). We installed the unit in the SSE facing largest room, and it kicks on about when I wake and morning sun starts to warm my room, and during the day is keeping the upstairs from ever getting within 15 degrees of the daytime summer temps upstairs the past two summers. The heat inverter was nice to use without turning on the furnace for a few nights this past week where it dropped from 80's back to 40's in Madison WI. You many want to supplement the adhesive weather stripping for the two slide out panels, where they abut the inside of the window opening and leave a fine crack (I haven't yet sealed it; the crack is too fine for insects so far), and at a couple places under the unit that did need the provided weather-stripping. I think this is a good buy, assuming it endures. These two units (<$1000 total, 2 hours installation total) appear to suffice in place of the 3 quotes of $10,000 - $15,000 for contractor installed central air in this old radiant hot water heated house with no prior air duct engineering. (Can send my kid to school another year instead!)

12,000 BTU with heat. Does not blow cold air, cool air only. Box was opened from the bottom and unit had been delivered upside down due to box being opened from the tape seal being broken. It sat on my floor right side up for over a month after I brought it inside. This was supposed to be a new unit but it was not taped on the unit itself in the places my other unit was around the filter housing and vent opening. I was hoping to get help to install from acquaintances but couldn’t . I was able to get it set up by myself with a bit of a struggle.It only blows cool air ,not cold. Had it set to 74 on auto all night long , and when I woke up it was blowing HOT air and my living room was very hot, and was not set on heat, had I been able to install before 30 days I would have returned the unit. I’m not happy! Big disappointment. I had also ordered a U shaped same brand 10000 BTU and installed it in my bedroom. It’s whisper quiet and blows ice cold air , works great, best A/ C I’ve ever had, and I could not be more pleased with it.

I live on the Gulf Coast of Texas and this year's El Niño summer has been exceptionally hot. I have a small greenhouse that I can usually keep cool with an evaporative cooler, but not this year. The house is made of twin-wall polycarbonate, so it doesn't provide much insulation. This hot summer left me no choice, but to get a window unit to help cool the greenhouse. With the exception of inserting the batteries into the remote control, the unit comes ready to go right out of the box. I set it at 79 degrees using AUTO temp and AUTO fan. With outside temperatures ranging from 103 - 109, the greenhouse stayed around 81 during the day and exactly 79 at night. That's a 28 degree temperature reduction, but keep in mind, that's in an uninsulated building in direct sunlight. It's really remarkable. The unit does not run continuously on high speed; instead it adjusts its speed to meet the needs at the moment. The other morning we had a cold snap (haha) when the temperate got all the way down to 76 degrees. I went into the greenhouse and was shocked to find that the unit had switched over to heat mode and had held the temperature at exactly 79 degrees. I checked outside and it was working as designed; hot air blowing inside and cold air blowing outside. For what paid for this, it is a tremendous value. NOW MY COMPLAINTS. My biggest complaint is that in bright light you cannot see the numerical indications on the control panel of the machine, nor can you see what mode it is in. It is a contemporary design where the indicators shine through a translucent white panel in front. It looks great at night, but not in the day. You can read data off of the remote control (which has an excellent display), but that's just what you asked the machine to do. There is no way of knowing if it received the message. My other complaint is that there are some functions that are ONLY accessible via the remote control. The swing mode of the vent is the main one. If you lose or break the remote, then you are out of luck. I do not use the wifi mode , so maybe it's possible to control it via wifi. I would have rather had them not include the wifi features and reduce the price. All in all this is a great machine and a great value.

Latest update after summer heat wave: This is a very efficient air conditioner. Buy it for summer use. It blows cool air nearly immediately and runs at twice the efficiency of another brands "quiet" inverter unit. Average daily use in same setting is 2 kwatts versus the other brand's 4 kwatts. This box shaped unit is much quieter than the U shaped unit, which essentially acts like a tuning fork anytime the compressor is running hard. Again, winter use is a no go- it runs the compressor twice as hard (burning 600 watts per hour vs typical 300) and is much louder in heat mode... rumor has it there was a software update to run at lower temps but I would not want to. It's more efficent to remove the unit to keep the wind out. Winter Update: Both of my Midea units are poorly sealed internally. See video showing the strength of pressure change passing directly through the internals of the unit. Video shows the U shaped unit, which is actually the less problematic in terms of internal leaks because of the slim connection to the outside half. Due to this fault, I cannot leave the reviewed heating unit in place through winter to use for heating on mild days. The blast of arctic outside air infiltrating into the house through the internals of the unit defeats any gains from heat pump technology. I will have to remove the shell of the unit to silicone all the leaks. Additionally, this explains why in summer the humidity inside was worse than ever- these units are poorly sealed. I contacted Midea customer service to adivise if there was an internal vent to close. They said all their units are internally sealed and were quick to blame installation. Given that no installation method could cause a constant breeze through the internals of the unit, it is evident that shoddy manufacturing practice is being covered up. As of now I cannot recommend any Midea brand AC. I'm feeling less hurt that this model has been stupidly discontinued instead of improved upon. Original review: Don't fall for the U shape gimmicks. This unit is just as quiet and efficient, plus currently a lower price than the big box store has for the U shaped one. But it has the ability to heat your room using the heat pump for 90 percent of your waking winter temperatures. Heat pumps move heat, rather than generate heat, allowing for much greater efficiency than any resistant coil type electric heaters. Pairs nicely with natural gas furnace running at the extreme low temps. I'll run the window unit in the bedroom at desired temp and leave the furnace on for whole house at my minimum house temp. Pros: 1. Much quieter than that other high profile brand that claims to be whisper quiet. There's no water slopping sounds from the compressor fan. It doesn't sound like a jet engine about to take off either. It's a nice consistent wind whoosh. 2. Are three 12k window units (36k total) more efficient than the single 18k mini split unit that I failed to get a leakless instal 2 years ago? I'll check the utility records after this season is over. Cons so far: 1. it frequently trips the 15 amp GFI on the start of my outlet circuit at start up, with no other draws. GFIs are generally not friendly for high amp draw appliances with built in GFIs on the cord, so I need to run a dedicated outlet for each AC. (The U shaped model does the same thing) Update: I simply removed the GFI outlet and the AC runs fine on the circuit. Again, GFI outlets are notorious for tripping appliances, even under a correct load. 2. There's no real temperature control when on dry mode... Blew thru the original setting of 72 and brought the room down to 67. Would love to see and set to a humidity percentage while in dry mode. Haven't tried the app or remote yet. (Might have humidity display options there) 3. Product arrived dented. Plenty of Styrofoam in the packaging, but this could be displaced by a couple sheets of 3/4 inch insulating foam on all sides to be cut up for window panels. This type foam would be much stronger protection for packaging too. Update: The dent is not noticeable once installed and has not affected the performance at all.

After central heating and air went completely out of service last summer, I have been forced to look for alternatives because replacing the outrageously expensive central A/C is financially impossible at the moment. So, I have bought Frigidaire, Soleus and now Midea window heat pumps/AC to match or exceed BTU rating of broken central unit. The Frigidaire is the normal (non-inverter) style compressor heat pump. Works FANTASTIC even in sub-zero temps with defrost cycles but is really loud. The Soleus is an inverter heat pump and VERY quiet. It also works extremely well in very cold temps with excellent defrost function. The Midea is extremely quiet would be easily the best of all three but for one fatal flaw. No defrost cycle. It will not work below 41 degrees F outside. If your outside temps never go below 41 degrees overnight in the winter, you may not need a heater at all. This unit would be perfect and by FAR the best window heater/AC on the market if it could only defrost. What were they thinking? They snatched defeat from the jaws of victory here. Update: Sometime this winter Midea did a software update on this unit over WiFi since I have connected to the internet. They MUST have installed a defrost cycle. Because one day it just started defrosting when it was FAR below 40 degrees F. It formerly would give a low temp error code. This means it was software limited to not operate below 40. But now, it worked great even in the mid 20 degree F nights I had this winter. So, I bought another one while I could. Update#2. I did get another one as stated above. The newer one has different firmware, that I cannot update/change from the app for some reason, than the other one and DOES NOT work as well when it goes below 40 degrees F. So it is definitely something about the firmware involved. I have two identical units in the same house with different firmware and one continues working and defrosting LONG after the other shuts down and shows "Lo" error code.

I love this little thing, but she’s disappointingly cheaply made. The quality of the electronics is poor and I would look to see if any comparable competitor products come on the market before buying another. The entire right side of the touch controls has never worked / is totally unresponsive to touch at any level of pressure (I remember seeing another review complaining about this too so it seems like there is a pattern of faulty control pads), but I didn’t try to exchange it because I control it with the app anyways (not sure if the remote works because it did not come with batteries and I haven’t gotten around to buying any) and cannot really lift it myself. This worked amazingly well the first few weeks but became a little more erratic after that, in that it seems like the temperature sensor fluctuates and it’s active more than I’d expect… when I first got it my apartment would feel cool with it set at 76-78, and more recently there have been times where I had it set at 74 auto and came home and it was 79 degrees and humid like it hadn’t been running all day (this has only happened once, but after it happened I found that I needed to keep the temp lower than before around 72 to be comfortable (which is what I’ve generally had past ACs at, but for the first few weeks 72 for this unit felt like 65). It seems to be on constantly, but it is pretty quiet and my electric bill is somehow lower than it was before summer so that is great. The ability to control it via an app and the heat pump functionality were big selling points for me… the app works well enough, but it was confusing to know where to get it (the app is not made by midea, which is actually a violation of Apple’s developer rules/it could easily get kicked off the App Store for that), it keeps bothering me to clean the filter every other day (since the first week I turned it on) even though the filter is always clean/unobstructed, sometimes the app will not be able to connect to the unit, it randomly turns off eco mode/resets things for no reason, the UX is poor, etc. This will give you the features of a mini-split in an apartment without hiking your electric bill, but there are clear quality issues and defects that make me afraid about its longevity.

I have been using this window AC for two months now. And I have to say, it is the best window air conditioner I have ever had. It is so nice to have the variable speed fan and compressor, so that no more noise than necessary is generated by the unit. Other ACs run ear-splitting full tilt all the time, with the temperature swinging up and down as the compressor cycles on/off. This "inverter" unit runs at low speed and even stops running when the room temperature is at the set point. Then, as the day heats up, the unit increases fan speed and cooling power to match the heat load on the room. It's just like my more expensive mini-splits. My only complaint? The accordion wings are not wide enough to close off my window on either side. Seriously, how much would it cost to add a few more inches to the blocking panels so that more installations could be fully closed? That shortcoming, however, is not enough to lower the rating for this product. It is A+++ and has operated flawlessly so far.
