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

I really like this unit. It has efficient heating and cooling. It's easy to install. Quiet and does a good job. The heat pump will shut off when it's below 41 f. I have found one exception to this. If place in a window over a south facing concrete porch. The sun is lower in the shy in winter. This allows more of the sun to hit the cement. Under the porch roof. It absorbs more heat during the day and radiates it off at night. This unit will capture that heat and continue to heat when the rest of the air temp is below 41f. This really does extend the heating past the 41 shut off temp. The opposite is true in summer. I have a wood stove for when it's below the operating temps. I live in Arkansas on top of the mountains in Solgohachia. I currently have just one in the center of a 16X80 mobile home. I believe 3 of the smaller 8000 btu would heat and cool it nicely. It's surprising how well just 1 does. Currently heating the living room kitchen and dining room. I don't know how as it says it only produces 7000btu of heat and uses about the energy of a 1500 watt space heater. It's almost Christmas. For me the low white noise of the unit is relaxing for sleep. The filter catches a lot of dust and is easy to clean. I plan to get 2 more. Possibly one being the 12000 btu. I Got the 12,000 btu for my mom and it also does great. With the option of good affordable zone comfort. I prefer this over central heat and air. I like it that much. Just have supplemental heat when it's too cold for the heat pump to work.

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.

So this product does do what it's supposed to do and that's cool my room very well. It was relatively easy to install, I put it together with the manual and installed it myself in a few minutes. Took at little while to get used to the settings but I eventually figured it out. It has a high/low fan setting and a high/low cool setting on one knob, as well as a separate knob for how much cooling you want the unit to do (you can choose between 1-7). I've closed my door and windows and set it to high cool and the max cool setting (7), and my room temperature went from 81 degrees to 73 degrees in about 45 minutes (photos attached). On the same settings I think I went from 84 to as low as 66 after probably 2 hours a few days before writing this review. Also, my room is pretty much a square. I believe the walls are all 12 ft long and 8 ft high. Definitely measure your room to make sure you're getting the right size AC for it. This unit says it cools up to 150sq ft, so measure the length of 2 walls and multiply them to get your square footage. Mine are all 12ft long so 12*12 = 144sq ft. Depending on the temperature outside I either keep my 2nd window closed if it's the same temperature or hotter outside or I might open it if it's cooler outside. If it is cooler outside than it is inside (like at night) then you can just turn on the fan, which I believe will push fresh cool air from outside to the inside of your room instead of running the AC's cooling unit. I use my phone to check the outside temperature and then have a cheap battery operated thermometer that sits on my desk inside my room to tell me the inside temperature. I've attached a video so you can see and hear the unit for yourself. Only reason I am giving this 4 stars is because of the noise. It's doesn't make a whiny noise nor does it sound like anything is mechanically wrong or broken, it's just that the fan is louder than I expected, even for the lower setting. I kind of wish it had one more setting where the fan was running at about half it's current lowest setting to maybe cut down on noise a bit more. But it's nice that I can crank it to high cool and the max cool setting and close the door/windows and leave the room for a bit, then when I come back I can turn the fan and settings down for a bit and be nice and cool. Sometimes it gets so much cooler that I even have to throw on a hoodie. One more note: I also run a gaming pc in my room which drastically affects the temperature, so these newer temps with the AC are while my pc is on and running. Without that the AC unit probably can cool a room of a similar size even easier. But again, other than the loudness of the fan it does work very well.

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.

I bought this since I really liked the functionality of a previous Midea unit I bought for my shop, but didn't care for the u-shape style. This one is 8000 BTU, and also has the heating function. It is basically a heat pump in a regular square window unit form factor. I bought it to help cool the bedroom, and heat function was just a nice "bonus" that I didn't plan on using. I installed it early April, and the temps dropped the next day. I will say that the heat function works very well, and while the literature says 41 degrees F (5 degrees C) is the minimum outdoor operating temperature, it seemed to work down into the upper 30s (around 2 to 3 degrees C) on a couple nights. In the app, this model actually shows up as a "split unit" so you know it's a real heat pump. Pros Cold when you want it Warm when you want it (within reason) Much quieter than the generic "on/off" style window unit it replaced (this one is inverter driven) Scheduling and long distance operation via Wi-Fi and the app is pretty easy Included remote works well They include locking screws and insulating tape for installation. The top groove and side blocking pieces are included, but you have to attach them Cons If you have sensitive hearing, you'll hear the high pitched whine from the inverter system My LED lights on the same circuit as the AC flicker in a slightly annoying way In auto heat/cool mode, the "dead zone" AKA "hysteresis" is a bit too small. The system will switch between heat and cool a lot if the temperature is close to target Unit was a bit wider than the old AC, and I had to get creative with the side blocking pieces and insulating tape At certain frequencies, you may get some vibration in the wall/window from the AC. I get it a bit, but it's usually while it's speeding up so it only lasts a few seconds. The manual states this happens due to "weak walls." I live in a double wide, so maybe? I'm really being a bit picky, because overall I'm totally satisfied with this unit! I like that it only runs as hard as it needs to, and the 8000 BTU size is great for a medium bedroom and bathroom combo. I strongly recommend it so far. Overall power draw is typically between 200 and 400 watts while running, it does seem to use a bit more power in heat mode and gets close to 500 watts at times (according to a KILL A WATT meter) Stand by is under 2 watts

Purchase of the year! I split my time between the West Texas desert and my DFW home. I put this unit in my camper because the smaller one it came with couldn’t keep up with the HOT and COLD West Texas climate. This AC keeps my camper cold even in 118 degree heat. The heater function is a life saver too because I don’t have to use propane to heat my camper all winter. I save thousands of dollars just in that alone. It says the heater won’t work below 41 degrees, but I can tell you it certainly does and keeps freezing nights in West Texas quite cozy. I used a temperature tracking thermometer until I could trust the auto functions of this unit, and I can tell you the temperature regulation is spot on.

Let me start with the notes/limitations: * This thing weighs *a lot*. That weight combined with its center of gravity sticking out of your window quite a bit further than standard window units puts quite some stress on your window frame. In other words, If your windows are not sturdy then this unit is probably not a good choice. Silly as I am I went a step further and framed a 14x19 hole in the wall underneath the window. So now it functions as sort of a PTAC (Those things you see under the window in a hotel.) * It heats with outside temperatures as low as 41F but not lower. For those days that the temperatures go below that you need to get yourself a $15 wallyworld space heater. How often you are going to run that space heater depends on how far south you live. Don't wait until you need that space heater because they will be sold out. Get it now. Then the things I like * It's not your typical window rattler. This thing is unnoticeable quiet. It starts quietly and it runs quietly. * It's a inverter type A/C with heat pump capabilities. Look for any A/C system with those capabilities and you will be out at least $600. This thing is a bargain. * The unit is easy on your breakers. It does not come on with a bang and a lot of the time it will pull less than 200 watt. You can run like 9 of these units on a 15 amp breaker. * Only 3 of these 8000 btu units cool as much as a typical 2 ton central A/C unit. * This thing is a DIYer's dream. It sips power and when installed as a PTAC it cools and heats a home beautifully. No EPA 309 certificate needed.
