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!)

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.

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.

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.

I live in Southern California where it rarely frosts. This 12k btu unit is cooling and heating half of my 2k sq ft house minus the 3 bedrooms. Most nights don't get below 40. The heat will shut off on my 12000 btu unit at about 36F even with the latest firmware. I bought this mostly for the heater and it has been performing well all winter. For my climate, it's almost perfect. For me, a 28F shut off would be ideal. I understand that is is difficult to produce a heat pump at this size and price range and have it heat at very low temps. It can only reach about 67F inside when it's in the 40s outside but that's fine with me. It's pretty loud on the outside in my experience, louder than the LG non inverter window AC it replaced. Pretty quiet on the inside once the set temp is reached and held. It also vibrates a bit when first turned on and working hard. The classic app works pretty good, the new one doesn't seem as good but you aren't forced on it yet. The biggest issue I have had is the condensation on the outside. It has the spray the water back on the condenser design which, when humid, creates way too much water and it soaks the whole outside unit including the outside wall. The spray the condenser design doesn't work well when used as a heater so I had to drill a small hole at the back on the bottom to drain the condensation. This has worked well. No more water all over the place. They need to add a drain plug so you can choose to drain it if needed. It needs a metal grid on the back to protect the fins of the condenser. I added one. The filter is flimsy and doesn't give the confidence that it seals very well. It does leak a little bit of outside air to the inside no matter how well you seal it to the window opening. It's an efficient AC and heater. It uses less electricity than the smaller 10K btu AC it replaced. I would buy it again if it's going to last. I hope this heat pump technology continues to evolve for in the window units.

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.

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.

Nothing but problems since they were delivered. We purchased 2 of these in April 2025. The first ones that were delivered, were both damaged. One of them had a stripped electrical cord with wires showing. The second literally had forklift damage on the side *I am a forklift operator and know what that damage looks like*. We returned those and asked for replacements. Those came in and were doing great. Both were installed immediately in a Texas summer. They did ok. They honestly don't live up to their advertised power. One has been running perfectly since. The one in my room, however, started having issues almost immediately. One thing I like about this unit is the "led off" option on the remote. But the remote stopped working within the first month. Then I remembered the box saying there was an app. So I went to download that. The app has been out of service since 2016. But it still offers to let you control it through another app. I downloaded that. Went through all the steps. It would not connect. So I made a dimmer sheet with led cover stickers for the front of it to block the led so I could sleep. This happened at about 3 months. At 4 months, the led buttons stopped working one at a time. So, I have to put it all the way on "heat" and count how many times I press the button so I know when I get to "cool". At about 5 months, my fan flap broke and froze open in one position. Now it's 8 months later and the heater turned off on the night it got down to freezing. Luckily I have a backup radiator heater to keep my room warm. Honestly, I'm ready to take this thing to a rage room and end it's suffering. Please do not buy this unit. Please save yourself the headache of a wasted $400-$500. I'm trying to get help now because apparently, midea has some units they are recalling and you have to go online to see if yours is one of them and now I have to find paperwork. I hate this unit. I hate this company. Hope you make the right choice and have a wonderful day. Btw...it's currently turned off in the picture. Which means the flap on top should be closed. But it's wide open.
