MideaDuo 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

Better than I expected. I’m using it for a living room of about 300 sq ft. When I setup it up, the temperature in the living room was 94 degrees Fahrenheit. The outside temperature was 92. Three hours later the living room temperature is 80. I suspect it will drop lower. I put the unit in the balcony door. Just followed the casement instructions and added corrugated cardboard, which is an insulator, to fill in the door space. That door gets direct sunlight from about 1pm to dusk. So it really gets hot at those hours. The sliding door is 6’ x 7’. Thats a lot of sunlight and glassThe only downside side is the plastic clamps. They take some work to get them to hold. Will eventually use some insulation tape. To hold the exhaust fixture in place. That’s a small price to pay for a fabulous unit. Because the unit was not designed for a balcony door, I’m using my 3D printer to make clamps and door guides for a better fit.Now that the room is cooling off, the fan speed has dropped and it is much quieter than I expected. I can’t say enough about this. Granted, it’s only the first day. I will update it again. So far, it’s handling Savannah, Georgia’s debilitating summer heat and humidity. Right now, my central air has succumbed to Savannah’s heat, and it may be weeks before it’s rehabilitated. This has been an absolute life saver. I’m now contemplating getting a second unit for the bedroom. The unit there, out of respect I will not mention the name, is not up to the task. When the central AC is restored, I will keep these and move them to my workshop in the garage.

If you're considering purchasing a MIDEA portable AC, here's something important to know:MIDEA offers a one-year warranty and five years on the compressor—but what they don't tell you is that if the compressor fails after the first year, you have to pay for a technician to diagnose the issue and submit a report to MIDEA.I bought a 14,000 BTU unit for $690 and only used it for 10 months—five months during the summer of 2023 and five months in 2024. Now, as I try to use it again, it's no longer cooling because the compressor has failed.MIDEA expects me to pay out of pocket for a technician visit, which can cost anywhere from $100 to $250, just to even begin the warranty process.In the end, I decided to buy another Black and Decker AC instead. I've had one for five years without a single issue.Worst customer service experience.

I am pleased with this unit. It worked perfectly over the last few days when the temperature hit 96. I had set the unit to 75 degrees F and let it run. It maintained the temperature in the area to be cooled (700 sq ft) at 75 to 76. Not bad. t was initially noisy at full throttle (just set the temp and let it work), but that seems to have calmed down. It was painless to install, but you need to see the Midea video on YouTube to get full value out of the combined info from the manual and the video. At night, it was hard to tell if the unit was running, it was so quiet. I have one smallish ceiling fan running at its slowest setting that I think helped keep the air stirred properly.Based on this sample of one, recommended.

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 productI 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 operatin 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.

Should have bought years earlier. I like the feature of dual hose. We use it in Colorado with low humidity and daily temps that swing 30 degrees from high to low.. We shut the house up early, turn air on around 2pm and avoid that uncomfortable heat at 5pm. This has definitely been a game changer for us.I hesitated for years because I have crank out windows. Was not sure how to close up the window for hose without it looking "ugly". There's a company out there - Martinson Manufacturing - that offers custom made plexiglass solutions based on your window and hose type. With this option, I bought the freestanding AC and have been very pleased.
