Midea Duo 14,000 BTU (12,000 BTU SACC) High Efficiency Inverter, Ultra Quiet Portable Air Conditioner, Cools up to 550 Sq. Ft., Works with Alexa/Google Assistant, Includes Remote Control & Window Kit

Update - 4 months in -------------- Decided to do a follow up since it's getting into the summer time now and I've had this now for the past 4 months. For context I live in the inland empire with dry desert California climate. As we speak right now It's 97 degrees in my room of around 350-400 ft. I bought this to circumvent issues I was having with my central AC that my landlord is being extremely stingy about getting properly fixed that froze on me last summer, and even froze on me this week when I turned it on again for this extremely hot weather. Ive primarily have used it before in hot weather so I knew it would work but I was worried that I was crossing the threshold of efficiency where it would be better to simply use my AC instead of doing my hacky solution. Except for trying to get the ac fixed and this past week I have not turned on my AC a single time during this summer or this week with over 90 degree weather. And this has been not only working, but still working more efficiently than my AC for my space. It's really good at being able to regulate itself at a decent level when your room is at the temperature that you set. For my case however I do run this at 78, which is fine for me. The degrees it shows will be about 2-3 degrees cooler in your room to whatever you set it too, but I know that a lot of people like it way colder than I do in my room. The colder you run this unit, the less efficient it'll be, especially when your trying to work with extreme temperatures. I do suggest getting the warranty when you get this unit as the actual pipe you get with the unit is extremely flimsy and super expensive (around 60-100 dollars last time I looked). I had some damage on mine from setting it up, but found a workaround with drilling in screws instead to keep it in place, but I still got a replacement sitting in my room after sending them pictures from that. There are automations that come with the app that would help to make it more efficient I haven't played around with, but I suggest you do so as the only issue I've had running this consistently is it running when it's cooler outside, but my room retaining a lot of heat naturally due to how it was built. If you do this, I suggest getting an indoor thermostat so you can control when you turn it on conditionally by both your indoor temperatures and the outdoor temperaturees, as I've found in my case especially after dark it'll be cool outside but super hot in the house because of the heat cooling off from the walls. -------------------------------------------------------------------- Im basing this on my first couple of days using this unit from a unusual heat wave for the past few days in cali, and not off any long term use from using the product I primarily was looking for a portable unit with the purpose of saving money in my small rental apartment. My AC over time has massively gone up over time and very likely needs to get an inspection but even with it working as intended, it's generally a very costly piece of equipment especially during the summer. I have an all electric unit - so the expense is already going to be higher than if I had gas, but the unit also being broken and older has also increased that cost over time. The unit itself is around 70ish pounds, so if you're looking to move this around upstairs, then I wouldn't get this unit. It is movable but you really want to utilize the wheels whenever possible. In my apartment, the 2 ideal locations that I would place this unit would either be my bedroom or my living room, which can both be accessed easily by wheeling it to where it needs to go. The installation of the unit is fairly straight forward. I actually have not done any permanent fixtures with the foam as I'm trying to avoid doing that as possible, but I haven't had any issues with the unit being semi fixed. The noise from outside seeps a bit more like this, but this also isn't a unit that I need to use all the time - as I really only need it when the weather gets hot. One primary concern that I have so far operating the unit is the hum of the refrigerant as it's going in the unit itself. The first couple of days it was making a very annoying audible sound that was mostly machine like, but it seems to have gone away after operating for the last few days. If you hear this noise, give it a few days to see if it goes away on its own. The other issue with this unit is the flimsiness of the installation itself. It's very easy to break the clips for your mounts, and the replacement cost for those pieces is around $79 dollars on midea's site. You have a limited warranty of 1 year on the unit itself, but I can see this breaking very easily after some time, especially if you move it around a lot. The unit has 4 modes, for mine it has a fan, cooling, and a dehumidifer mode. From using the auto mode it seems to do a fairly good job once the room is set to a certain temperature. Generally speaking though, with any AC, you should turn them on first thing in the morning when it's cool, so it doens't need to work as hard cooling your house. It's easier for it to maintain a cool temperature, then it is to bring down the temperature of your whole house. I've also seen people say "it doesn't carry air that well, but also try to use it in a 1000 ft garage, or some other weird area. This unit is specified to work for around 450-550 feet. My room is around 200-250, with my living room being around 500 ft with obstruction that makes it difficult to carry air if my doors are all open. If you need to carry air, grab a fan that can carry air in your room like a dreo or a vornado, or any kind of fan that can tilt or has the ability to swivel. My room says relatively cool, but my living room right now is at a different temperature without my engaging ingenuity around it, but I am able to circulate air into my living room by setting up my fans properly. It's just a hassle to do that constantly. Otherwise, for energy savings from my wattage hours it's operating at a much lower cost than it would to use my AC. Even if I needed to get more involved with adding more fans to circulate air in my house, that hack is significantly less than the amount of electricity im using right now. I haven't gotten a kill a wat to watch the unit, but from my bills alone, the total operation on a fairly hot day seems to be around 4 watts, vs my AC which would easily take 10 watts minimum even on an average day.

If anyone is buying this Midea Duo large portable AC please note the covers of hose outlets are completely open and all types of bugs and critters can get inside. So unless you have a fitted screen on the window you will have to rig something up. I called Midea support but they were not so helpful suggesting rectangular air vent filters which would not work. My solution was to cut up an old portable sliding window screen and use the mesh which is flexible enough to clamp on outside of vent hose. I have attached photos of before and after. Seems to be doing its job. The window attachment clips on the hose are not that tight and also there are a few gaps around edges of clips and on one corner of hose so some duct tape to secure it is also advisable. The provided insulation tape and window foam are not the best quality and the window foam is much too thin so be prepared to buy some better alternatives. The good news is it seems to be cooling well. It was 90 deg yesterday and I set the AC to 72 and it is set up by open door and made 2 rooms comfortable within an hour. No issues with any leaking on dry setting. For the cost I think quality control could be a bit better and better grade materials provided in box. Also be aware box has to be upright and watch the bottom corners for impact as not so much padding at bottom of box and wheels can get damaged easily. Initially pleased with the purchase in 2023. I would advise taking Amazons additional warranty though Asurian for peace of mind for 3 or 4 years as only 1 year provided by Midea. Update July 2025…..compressor no longer comes on and have only used for 2 seasons July August September so about 6 months total usage and cleaned and covered when stored. Today after setting up for summer compressor would not come on and tried all troubleshooting and calling Midea but no solution and as I paid over $600 for this not a very reliable product. Luckily I purchased the Amazon Assurion extended warranty and I was fully refunded within 15 minutes of calling. Downgrade my review and would advise to look elsewhere

I live in Sw Florida and have a 24 ft cargo trailer that i converted the front half into an RV for a business i started and needed a portable a/c to make it livable when in use. I first went with the Shinco 10k BTU portable a/c because of the price, i bought here on Amazon for only $230 lol, i got it, cut out a circular hole out of the floor and used a marine "porthole" with a cap that unscrews to vent the exhaust pipe throught the floor, and the cap screws back on when not in use. The machine was nice and quiet when running and blew cold air out but simply could NOT cool that little space (12x8 area), even with it being an insulated cargo trailer that i paid extra for. I was extremely disappointed and gave it a few days running and even at night it would barely be comfotable in there. I boxed it back up in disgust and sent it back! I started researching portable a/c's and quickly dicovered that it couldnt cool because of it's poor design (you get what you pay for!), it used the interior air for the heat exchange and dumped out enough hot air underneath the trailer to rival a clothes dryer which meant every bit of air that was sucked out and exhausted from the interior meant the interior needed to "make up" that amount of air on drawing in new hot moist air from the exterior through the cracks, it shot itself in the foot, extremely POOR DESIGN! On top of this, the exhaust hose created an enormous amount of heat itself, what a nightmare! This Midea unit uses a "dual hose design" 2 in 1 and it takes the outside air for the heat exchange then blows it back out through the same hose (there's actually 2 hoses inside the main hose, 1 for intake, 1 for exhaust) and no heat from the exhaust hose. This Midea unit with the dual hose design is amazing, it instantly starts cooling and within 15 min started up at MID DAY its already comfortable, in an hour its as cool as your home a/c in the 70's and living in South Florida is brutal in August, it's been 98 degrees here with near 100% humidity. This unit EASILY makes cool air to spare, i highly recommend it!

I received my unit from Amazon on 7/15 and have run it for the last couple of days. As is seemingly usual for portable AC units, the box came in a somewhat-distressed state (one corner completely bashed in) but did not seem to impact the functionality of the unit, so I'll consider myself fortunate. Impressions thus far: - Unit cools down my 450sq ft south-facing room without a problem. This room has insulation issues so I won't bother quoting cooldown times. - Runs fairly quiet - I guess as an inverter system the compressor sound isn't prominent but it's still there. On low speeds it comes across as slight "chirping" noises - not sure if that's the inverter board power or the compressor itself but it isn't offensive. On hotter days the condenser fan will occasionally go full beans and causes the unit to make even more noises but that's momentary and I'm not bothered by it. - At higher speeds, I can point the vents upward toward my vaulted ceiling and can feel air come down along walls in different parts of the room - pretty neat. - The oblong dual hose-in-hose design is interesting. I initially thought I could only point the AC unit "straight into the room" with the AC unit directly below the vent hole on my window but turns out if you extend out the hose long enough, say 4ft, there is some play in the hose to bend it horizontally such that the AC unit can be turned somewhat to a more desirable location of the room. This, of course, comes at the expense of having the unit placed further into the room it's what I prefer anyway. The hose is quite stiff though so side-to-side action is a bit difficult. - I love the Auto Fan mode - when it gets closer to my cooling set-point it'll slowly ramp down the fans as well as the compressor speeds. - Unit does 2.4Ghz WiFi and can be controlled via Midea's app. App generally works ok for basic functions (for what I briefly tested) but I haven't tried the Alexa integration. - Remote works well - I found you don't have to point it directly to the unit: point up, down, off to the side away from the unit, whatever - it seems the AC unit receives remote commands no matter what. Almost seems it's not IR-based. What I don't like or improvements: - Glossy black. With the exception of the faceplate (matte black) the whole unit is gloss black. After two days, the unit picks up fingerprints, lots dust, and is easily scratched by an accidental scrape of the fingernail and is easily seen during the daytime. Ironically, the color choice for the remote and power cord? White. - Though the louvers have a decent up-down range of blowing air, there are no adjustments for side-to-side so the only option is to point the whole unit toward the part of the room you need the direct air flow. - A bit on the pricey side. I guess if you want the inverter system, you'll have to pay more. In all, decent unit. Will get to play with it through summer but so far I like the unit.

This thing is incredibly quiet. Words cannot express how silent it is. It is like having a Dyson fan on low setting. That is how silent it is. A must buy for efficiency and noise reduction. The kit comes with everything you need for any window type and runs very cool.

First off, this Midea AC captured my imagination. After looking at so many ACs and even trialing 6 different ones, I thought this was the "golden ticket." I ordered it on June 30th and supposedly it was shipped by UPS on July 1st! I was excited so I waited....and waited........and waited for the status to say something other than "Shipped with UPS." On July 14th I gave up and asked for a refund. The Amazon guy was great and actually credited me back my money. While he was chatting with me I noticed that the status finally changed. Of course, it took another 10 days to arrive, possibly because someone was walking it to Oregon with a hand truck? Once it arrived, it was super heavy, but that just told me of its quality! My wife and I took it out and saw the HOSE. Not very flexible, but I was still enamored because of the hype. We hooked it up in our bedroom, and it was definitely more complicated than any other AC I've used. Despite some gaps in where the hose hooked to the plastic window frame thingee, it was good to go. The unit worked awesomely! Cooled down the room quicker than the others I've trialed and the sleep setting was whisper quiet, although it did have a couple of turbo moments where you may think it was going to blast off or something extravagant. At that time, I thought of writing a review to counter some of the one-star folks who I thought were just easily upset, but I decided to wait a few more days. Everything was good until the 3rd night we were awakened by a series of beeps. It did this a second time, but I was too tired to figure out what was wrong. I did notice that the air was just a fan so I turned it off and just opened the windows. It did this again the next night and again no cold air. Used windows again, but the next day I did check the "bladder" and it had a ton of water, more than I'd ever seen come out of these types of ACs. I dumped the dehumidifier tank too, and the device was again working. However, it beeped again that night and I was ready to scream bloody murder! I dumped water the next day, but this type, the cool air didn't start working, even after I dumped the water. At this point, I was certain that the others were right, and despite being "free," it was not even worth it due to the complications with which I was dealing. Overall, I won't give it only one star as there is some good in the device, but I would not recommend this machine to even my worst enemy!

When directly measured against the 12000 BTU Window U shaped AC this units increased energy usage AND air flow are not in line with the Window unit at all. Nearly 70% more AMPS used peak running and air flow nearly 20% less. Despite claims of dual hose airflow (eliminating heat transfer), measurable heat dissipation from the hose is present. As tested the energy savings were not noted. The hose heat transfer was not eliminated as suggested, and the airflow was diminished from what a "smaller" unit produced (and at a lower cost per unit). This is evident in their BTU ratings if you consider the meaning of the 120000BTU DOE vs 140000BTU ASHRAE ratings. In essence the unit "feels" like a 12000BTU unit with these numbers while sized at 14000BTU. At least that is my take on the standards and what I experienced real world at the unit itself (while in comparison with Medea's own window product). What I found was that the unit cost more to purchase, cost more to run, produced more internal heat transfer, and produced less cooling airflow than a 12000BTU U shaped window unit. Clearly the floor unit takes up more livable space than a window unit as well. For my money, this all equated to a poor purchase when the U shaped Window unit could be used instead. I would suggest the Window unit wholeheartedly. In cases that a window unit is unacceptable or undesirable: This unit used nearly as many AMPS as a 4 year old Midea portable "single hose" unit tested to compare this unit. That is extremely surprising as the Window inverter units use significantly less power than the older (mechanical) AC units I tested. This is really not the case with the portable unit I tested (and returned) with this purchase. I did not, however, that heat transfer was diminished by the design of the dual hose. It was not eliminated as suggested by the advertising. I have design questions and reservations about the dual hose design and that claim (not just real world tests that were easy to observe) but I did not test air flow or whether the hot air was recirculated due to the proximity of the intake and exhaust outside. So making statements other than easily measurable heat at the internal hose and room dissipation I will not make. Since I can state it improved (but did not eliminate) heat transfer inside, and that can be tested and recreated, I am confident in that statement (and I will not make a statement of the reason why... even if I think I can discern it). Overall: The unit works well for what it is. It is an improvement over previous generations of Midea portable AC units that I could compare to. It sis this in respect to slightly lower power usage, and heat dissipation from the exhaust hose. It did not perform, I feel, to its potential when in comparison to the Midea Window units. I would suggest the window units over the portable easily. If you are in the market, and can use a window unit and do NOT need the portability: You would be best served with the Window unit. If you need to upgrade a portable unit, you should consider Midea as a slight improvement over non dual hose and inverter based portable AC.

Cannot be happier with this unit. I live in central TX where the heat in the summer overwhelms my homes AC system. I tossed this in my living room because I read it’s nice and quiet but cools a large area. I shut the vents there and directed all the AC to the upstairs rooms and the whole house runs way more efficiently now. The house AC used to run 23-24 hours a day and now it’s 15-17 tops. This unit is VERY good. And the sound on auto is very quiet. It rarely gets loud to the point where we have to adjust the TV volume. And even so it’s just a slight bit to where we aren’t annoyed. I have plans to move into a different house later and this will probably be in a garage due to its ability to cool such a large area so well. The filter snaps out and cleans off easily and the app works great. Highly recommended.

I will come back and add more of a review about the performance once I have used this unit for a while. Here is a review about the unboxing, setup & first thoughts Unboxing: -The unboxing was extremely easy. You just remove the ties and then lift the box off the unit -You only have to lift the unit for a second to slide the cardboard out from under it, which is good because it is extremely heavy -The accessories were not secured very well and were rattling around inside the box Setup: -The hose being so wide and thick makes it hard to maneuver. There is not much give when it comes to turning the unit -I think we technically installed it wrong lol we did not use the vertical window adapter. But its in the window just fine and now the unit can face the way we need it to. -Connecting the unit to the window was extremely easy. The pieces click together, as opposed to the usual hoses that screw together and never actually stay together -We found the settings on the unit EXTREMELY confusing. They do not easily identify what they are. Low is a Y? Medium is a plus? High is a star? -The instruction manual makes no sense because they use the same manual for all their units -We did not use the remote or the app. We just hit power on the unit when we want to use it and it remembers our settings First Thoughts: -The hose is amazing. When the AC is running the hose does not get warm to the touch. No warm air is seeping back into the room -The unit is QUIET! Super quiet. Especially when on the low setting you can barely hear it running. I would have no problem sleeping with it on at night -The glossy black gets full of fingerprints and pawprints -The cool air mostly shoots upwards and its at its coldest when the vent is all the way open. You don't feel much air if you are sitting directly in front of the unit. I think it cools the room faster, but just beware if you like to feel it down at ground level

The very first thing I noticed about the Midea Duo 14,000 BTU portable air conditioner is how quiet it is. It's the quietest air conditioner I've every owned. The only time you'll hear the Midea Duo's compressor/inverter is when it's starting up. When the inverter/compressor starts up, it emits a high-pitched whine, which lasts for about a second. Subsequent to the starting up, the only sound you'll hear is the movement of the air that's being blown out by the fan. The Midea Duo 14,000 BTU in my living room is only 2 meters away from my TV and it doesn't interfere with my TV viewing. The Midea Duo 14,000 BTU is so quiet, I bought a 2nd one that I've placed in my bedroom. The Midea Duo 14,000 BTU is the first dual hose portable air conditioner I've owned. The dual hose design is noticeable superior to single hose portable air conditioner when it comes to keeping an area cool. The dual hose design draws in air from the outside, just like a window air conditioner. By bringing in air from the outside, the air conditioner is able to create a pocket of high pressure cold air. If you walk into a closed area that's cooled by a dual hose air conditioner, rather than a single hose air conditioner, you'll notice a dramatic drop in temperature. Most air conditioners use compressors that cycle on and off. Rather than cycling on and off, which creates variations in your room temperature, the inverter used by the Midea Duo speeds up, or slow down, to keep your room at the temperature that you've selected. The screen on the remote is backlit, which you'll greatly if you need to use it in low-light conditions. Once you set the room temperature that you want, you can sit back and let the Midea Duo do its job. I also have to commend Midea Customer Service. Two of the window slides, included with the first Midea Duo I purchased, had been damaged in transit. Replacements were shipped to me within a week.

I bought this unit in April 2024 after reading a review from someone in a similar apartment setup, and I’m glad I did. It cools my living room and kitchen area with ease, far better than the single-hose units I use in my bedrooms. I was so impressed with its performance that I bought a second one for my bedroom so I can sleep comfortably all summer. It’s also much quieter than my single-hose Ultima Cosa unit. In my opinion, the noise complaints by other reviewers are overblown. They may not have had portable units before, but these are not loud at all. Overall, this is an excellent air conditioner and I highly recommend it.

So glad I bought mine when it was available for $759, I came back and bought a 8,500 but unit for another room and it still works out cheaper than the current price for this one. I don't have any complaints about the device itself, it appears to be working perfectly. The only struggle I had with it was getting it to pair with my Alexa devices. It is advertised as working with Matter, but then during setup it says it's not a verified Matter device. When I installed the window kit I was very cautious with the clips, and I think anyone who buys this unit would do well to do the same as they feel brittle. The one thing with the window kit I do not like is the wife open holes where the pieces clip together, if you want to ensure the machine isn't turning on all the time or that you're not losing cold air outside—you will want cover them, I just put tape over top.

I bought this item after a personal recommendation from a friend who has the same unit and raved about it. I did my own research and felt so overwhelmed by all the options. I stuck with this one and I am glad I did. There are pros and cons with every unit. If you are looking for that perfect unit that is silent you wont find it. CONS: -it is loud on the high setting. If you are in the same room you can really hear it working but it can act like white noise if you let it. -There is no swivel available for the hose so it must be flush to the window that you are venting through. This makes it hard to get good coverage when it is pointing away from where you need it to be. I managed to get it angled about 8 inches and made sure there was no pull on the hose and that has helped. But it sure would be nice if these engineers could come up with a system that could be swivelled somewhat. But to be fair they are all like that. -The duo hose is both a plus and minus. The minus is that it is big, very big. Not the prettiest looking thing hanging out the window but it is effective. -effectively does open spaces very well so my living and dinning area and kitchen are well cooled but it can't go through walls so bathroom and bedroom are still a little warm, but cooler than without it. Perhaps if I leave it running 24/7 for a week or so it will eventually cool those spaces better too. -it says portable but it is big. It does wheel well but it is clunky and if you move it you need another widow insert. But this is common to all as well. -a lot of buttons to figure out to program it and instructions are very poor so a lot of trial and error. -Thermostat is not very accurate so running on auto it just never shuts off. I have to play around with the remote, which is the thermostat to try to find the perfect place so it gets an accurate reading . -the plastic clips that hold the hose in place in the window are very stiff, hard plastic and hard to release. They look like they will break easily if you use to much pressure but it can be a challenge to get the hose off. Just use patience and dont pull too hard. -it is a big machine so if you are looking for something with a small footprint this is not the unit for you. But I honestly dont know how it compares to other brands. Pros: - very powerful machine that cools quickly. -fairly quiet on medium fan speed and silky quiet on low fan speed. Nite mode is even more quiet. -wifi was easy to set up on my iPhone with their app. works well on wifi so I can program from anywhere. But the wifi and remote dont always say the same thing which is confusing but not a problem. -Remote works well, except thermostat is always a high reading. -I hired a company to custom make an acrylic widow insert and they did a fabulous job so it is professionally installed in the window. But the downside is that its not easily ported to another window unless I want to pay to have a second one done. -casters on wheels are very good, durable and rolls easily, even on carpet. -cools very fast. Had my windows opened during the day when I was out and came into a very hot apartment. Closed all the windows and set it on high at about 17C. The place was cooled down in less than 20 minutes. I usually start the day and crank it up high as I get the morning sun. After about 30 minutes on high I can set it on medium the rest of the day and in the evening I set it down to low. Bedtime I use nite mode. So far this has worked at keeping a constant temperature. The bedroom seems to be cooling each day so I am hoping that running it constantly 24/7 I should have that room cooled nicely in about a week. It is cooler now but not as much as I would like it to be and I dont want to be moving it from room to room. -still learning what settings are best and when and for how long so a lot of trial and error but this is my first portable air con so it is a learning curve. -had it running for about a week and no water to drain. Havent used the dehumidifier yet so I dont know how often one will have to drain when one uses that. But on air con mode it doesn't collect a lot of water. -Registration was easy. You also get a coupon for an additional 3 month warranty if you scan the bar code when registering so a nice add. -Overall very satisfied and I guess I should be at this price point. It is an expensive machine. -The duo hose is nice. Yes big, but it works well to prevent the hose from getting warm and in recirculating the air. Duo hoses are better at keeping external smoke out, so I have been told. Today was the first day I did not smell smoke from the forest fires so I guess I was told right. Was also told there is no air con that will totally prevent this but it was a big feature for me. I happy with the job it is doing. Havent had my first electric bill yet so I will see what this is costing in another few weeks. If it is outrageous I will add additional comments. But the model is on BC Hydro's list of rebate models. I havent applied yet but they are offering a $50 rebate for select makes and models. UPDATED AUG 29: As feared the plastic clips that hold the hose in place have begun to break. They are so stiff. Why can't they use rubber instead of hard plastic. The hose is very hard to detach from the window insert because of this. One clip has now broken so waiting for the other three to break. No idea how to go about replacing these things. A friend told me to use strips of duct tape on the broken one to hold it in place so I will try that. But there has got to be a better way to manufacture this thing so that it is easier to detach and less likely to break. Gotta go check for replacement parts now I guess. I'll write to manufacture re warranty and let you know what they say. UPDATE 2: Regarding the app. As others have said it does not work on 5G so you need to be able to use 4G or 3G. Luckily I can set my phone to 4G. The app works very well with an iPhone. easy to install and set up. I no longer use the remote control as I find the app easier. As well, you can set the fan speed to more than just hi, middle or low. You can actually set it exactly, like to 33% or 21% etc. It also works well when I am out and want to turn unit on or off before I get home. On sleep mode you have more control options as well. I did not buy because of the app but I am glad I have it. I also fine the thermostat is more accurate on the app and it provides both outside and inside temperatures. Update 3: Manufacture is shipping a replacement part due to the broken clip. Still dont know how it will hold up over time. But the customer service response has been very good. Part is back ordered so it may take a few weeks. I can still clip it in with three good clips I will repair it for next summer as it is almost time to put away for the winter.
