Midea 12,000 BTU Smart Inverter Air Conditioner Window Unit with Heat and Dehumidifier – Cools up to 550 Sq. Ft., Energy Star Rated, Quiet Operation, Electronic Controls, Remote Control, White

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.

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.

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.

When this unit arrived, I inspected it and I immediately noticed damage to the back of the unit and the inside evaporator coils protected behind the filter and removable grill cover. The box had no signs of visible damage, and none of the plastic on the pull-out filter grill was damaged. I requested a replacement and had to go to UPS to return the original unit. The 2nd unit also arrived with no damage to the box or the front of the unit, but also had damage to the evaporator coil behind the front grill and the removable filter. This leaves me to conclude these units are leaving the factory in this condition. Once the unit was put in the window, I noticed the foldable panels don't hug the sides of the unit and leaves rather large gaps. I used foam insulation board to block the foldable panels and cover a majority of the gaps. As for cooling, this past summer of 2025 was noticeably hotter than past years and this unit held up through all the days of high 90 degree weeather an over 100 degrees. I didn't notice the heat wave inside my home. My electric bill was also slightly lower than anticipated. On most days it was rather quiet but not completelly silent. I like to mask the street noise outside, so I wasn't bothered by it not being silent. There were a few times the AC would kick on and vibrate the entire wall and become rather loud, prompting me to shut the entire unit off. It would stay on for multiple days, nonstop and the inside temperature using an independent digital thermometer was always consistent with the desired setting. Over night using the dehumidifier mode would drop the room temperature below the desired setting, however, I didn't mind. Over all its a good unit that provides constant tempreature monitoring dispite the item arriving in less than perfect conditin from the facttory. It's not loud but not silent. It's pretty energy efficent considering how hot this season was ans how often it was used when compared to my electtric bill. I am not disappointed with my purchase. I also appreciate the payment option Amazon made available, so I didn't have to drop $500 in 1 payment since I don't use credit cards

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.

I was optimistic, but like many others, my unit arrived damaged. It's unfortunate that these units are just not properly packaged for shipping based on their weight/size. The unit I received has very obviously been dropped during shipping on its back where the coils and lots of other soldered components are located. I went ahead and installed it because replacements are not currently available. I elected to let the unit sit unpowered for 48 hours after install to allow the compressor oil to return to it's intended position since the unit was clearly not kept in the proper orientation during shipment. Some of the softkeys on the unit itself don't seem to work well, or at all for some of them, but other than that, so far it seems to work ok though I'm honestly concerned the damage that occurred during shipment may cause premature failure. I contacted Amazon and CS was very helpful. Because there were no replacements, I ended up receiving a partial refund after sending photos (this was maybe the most painful part as the email size is very limited so even 2 pictures per email was too large and zip files were equally problematic). The phone App seems to work very well to the point I only played with the remote once (the remote is also damaged where the front top half looks like it was crushed or overheated to where the top and bottom don't meet on the sides and it feels like the top is flimsy/will separate if used a lot, but it seems to work ok at least based on the little bit I used it. It may just be poor quality control.). My unit has quite a significant low frequency vibration to it when the condenser fan starts up/stops (shakes the walls and sounds like a car idling outside) but once it gets up to speed it's not quite as noticeable. I don't know if this is normal or if it's from being dropped during shipment? I've had the fan setting on Auto during operation and from a noise perspective inside, I don't find it too annoying at all, and it's quiet enough to me that it doesn't interfere with normal TV volume or bother me when I'm sleeping. The side curtains don't really seal the sides well when attached, especially in the lower corners where the unit sits on the window sill. I ended up caulking my unit in and I ordered a window AC insulation kit that I'll be installing this next weekend to help seal things up and provide a little more finished look to it. I wish it weren't damaged during shipment, as it would help me better estimate whether it's operating as intended and I think it could've easily been worthy of a higher rating, but it seems damage during shipment is the norm based on other reviews I've read here. I'm in the second week of using this unit since receiving and installing it. Overall, I think I would buy this unit again as it seems to cool well, and I hope the heating function is as effective down to the 41F outside temp limit for supplemental heat.

The unit works great, however, Midea should be ashamed of themselves. I bought this unit due to another unit being recalled that I bought two years ago (U-shaped unit). I figured since the company was standing behind its product I'd upgrade and buy an even better/bigger unit. The recall was for $300, the new unit $500, and I could sleep easy for a bit of extra cash. Over six months later I am still waiting on a refund for a defective and hazardous product, have followed all of the steps I've been asked to do, and end up arguing with the recall center on a weekly or bi-weekly basis, never able to get to a supervisor or achieve any sort of resolution except false promises and the need to call back the next week. The recall center is apathetic at best and cannot be bothered to fix a two minute address issue in their system. Midea hired out a third party for this recall mess, but in the end it is their responsibility to make this right. I buy a lot of their products, from dehumidifiers to AC units for both out house and relatives', but it's time to find a new company that stands behind their products in deed, not just empty words.
