    • A great value
Oh THIS is the portable AC I should have bought the first time. A couple of summers ago I bought a Newair AC that seemed dandy. But it couldn’t cool all my space. (It wasn’t rated to, so no problem.). This summer it didn’t work. An area I don’t think they told me to clean needed cleaning. I cleaned it. And the fan that pushes the hit air outside wouldn’t turn on. So I just bought a Midea portable AC, refurbished so much less expensive than new. This is the unit Wirecutter recommended, but I decided to save money two years ago. Anyway, it got here a couple of days ago. Much bigger than the Newair, and much stronger fan volume. Love it! Works better than the old unit, and cools more air, though they are rated the same. ... show more

    • Save your money...
So i will do my best to make this a quick a condensed review. Just don't... Firstly, the product listing is misleading at best considering i ordered a black version and received a white unit. Annoying but not the end of the world, given my circumstances I couldn't really complain and i needed a functional unit quickly. Bare in mind, though explicitly stated in multiple places on the product listing it was to be black it infact was not lol. Pros: Uh.. it blows cold air...when it wants too. Cons: The "dual hose" gimmick is really a hassle beyond words, it is very stiff and moving the unit simular to any other standing unit like this is not possible, the shape of the hose does not allow for side to side motion and versatility like other units like this. This is hands down one of the most frustrating "Smart" ac's ive ever had the displeasure of using. The remote is very poorly designed firstly and multiple functions of the unit are not use able with the remote OR app, it requires manually using button sequences on the unit itself such as holding the fan button to set continuous fan to be on (even when not cooling i preffer the fan running) the unit and remote do not interact together well, if you turn the unit on manually for example as you walk by, the remote is not useable until you turn it on with the remote (power on, and power on again before the remote communicates, this stands with the app as well) The app is useless i dont even want to spend 30 minutes explaining any further than that trust me its just flat out useless. The unit requires you to remind it to function on the room temperature which is very odd to me considering that's usually the whole point of a unit like this one. So you will spend a good amount of time hitting buttons (only on the remote of course, not the app or unit itself because that would all make to much sense) to check the room temperature, and cool to your settings. Otherwise it will just randomly say here have some cold air now im going to take a nap. Set at 65 degrees and the room temperature is 78 close enough. I cant even say it is energy efficient because it uses energy to power the leds while it sits idle and refuses to respond to whatever you set it to do. This leads me to my biggest annoyance, it does not remember settings. Temperature setting only. Everything else via app, unit controls, or remote has to be set up EVERY SINGLE TIME you power the unit on. The fan speed, or air flow angle, or "smart sense" even led brightness have to be reset every use, regardless of how you try to operate the unit. ... show more

    • THE BEST I'VE EVER OWNED
I have had more portable air conditioners than I can even count in my near 70 years. Most last a season, some window units can actually do okay for 3 to 5 years, but the majority of these upright air conditioners with the exhaust hose is good for no more than a couple of summers. It's usually obvious in the really hot part of summer that the compressor is struggling, and the capacitor kicks on and off continuously, as it discharges tens of gallons of water, never truly maintaining a constant and comfortable temperature until the sun goes down. The last thing I will comment on about most air conditioners with external exhaust hoses is about the dust. Within 72hrs without thoroughly dusting, you could grow a garden on everything in the room. NOW ABOUT THIS HEAT PUMP TECHNOLOGY. THIS THING IS WONDERFUL. It maintains the room at a constant cool temperature. It's almost silent, no compressor kicking on and off, and my electric consumption has dropped dramatically. I bet it hasn't discharged 5 gal of water in the last 3 months. There is virtually no outside dust sucked in and blown all over my house with this double hose technology. Because there is no compressor constantly kicking on and off and trying to cool the evaporator with outside air, it not only eliminates the dust, it takes a major heat sorce out of the equation. In my humble opinion it's the best and most efficient air conditioner that I have ever purchased. ... show more

This unit blows very cold air and is relatively quiet. Sounds like a whisper. I can work all day in my home office, talk on video calls, and not get a headache at end of the day from the ac noise. My unit did not come with the vertical exhaust adapter. I have a sliding window. I made my own acrylic window insert which I think turned out pretty good. Reference photo attachment. As others have posted my UL sticker is also blacked out. Evidently UL certifications are not typically valid on refurbished items such as these, so the reseller is supposed to black out the UL certification prior to resale. ... show more

    • Exhaust restriction
I have a Florida sunroom with a large wall of tinted windows and solar screens. After installing the AC, it seemed like it wasn’t cooling. The fan would run, but the air coming out wasn’t very cold, and the room temperature wasn’t dropping. After a lot of troubleshooting, I discovered the problem was not the air conditioner. My exterior solar screen was restricting the exhaust airflow too much. The Midea DUO appears to have built-in protection that reduces or shuts down cooling when the exhaust airflow is blocked or restricted. As soon as I removed the screen from around the exhaust area, the unit immediately started blowing cold air continuously and began cooling properly. Advice for other buyers: * Make sure the exhaust has plenty of free airflow. * Don’t place solar screens, shade fabric, furniture, plants, or other obstructions near the exhaust outlet. * If the unit seems to be running but not cooling, check for exhaust restrictions before assuming the AC is defective. Once I fixed the airflow issue, the unit performed as expected and produced cold air consistently. Hopefully this saves someone else a few hours of frustration. ... show more

    • Stick with an old window shaker
Lights started flashing and unit was beeping. Looked online to see what I could see and the only suggested fix was turn it off and then turn it back on and to try different power outlets. I turned it off and it wouldn't turn back on. Worked fine for about a month. These new machines are just doing way to much. ... show more

    • Wicked Good Units
These Midea Duo with inverter are WICKED GOOD. I’ve had several portable air conditioners over the years and have to say this Unit is the best yet. Gets wicked cold, and is quiet. I liked the first unit so much I bought 2 more $300 a piece that’s about 1/2 price and in Florida when its hurricane season these 110 volt units strategically place will keep my home comfortable and are a low draw on my 7500 watt generator plus being portable they are easy to relocate. ... show more
