"I have a 1400 square foot house that has, in the past, had three portable single hose units trying to cool it down unsuccessfully. I bought a dual hose Midea unit used and have since bought two more. Now the house is cool"
"I have it in my living room right now with vaulted ceilings. Keeps it 72 at 100 degrees outside so far"
"I live in South Fl so the garage gets super hot, with this running I can get the whole garage down the low 70’s maybe 68,69 with a fan helping blow it around."

"The important thing is, whatever brand you choose, it needs to be dual hose. The single hose models we've tried in the past caused so much negative pressure in the house that the humidity went sky high, along with the electric bill, and they didn't cool very well. ... Dual hose with an inverter compressor is the best you can do for performance and efficiency, short of getting an inverter window unit."
"Get a 2 hose portable or a Midea with it's 2 in 1 hose system. ... 1 hose models are sold in America 'because installing 2 hoses is too hard for that market to figure out'. They are the single dumbest invention in the history of inventions, blowing out the very air you are trying to cool."

"I have that unit and absolutely love it for its cooling power to noise output."
"One of the best things about them is, once they cool things down, they ramp down and run really quiet."
"Die midea hat aber einen Inverter und der ist viel leiser als der herkömmliche Kompressor in Monoblock Geräten. ... während du neben der midea schlafen kannst"

"The inverter part is key. It saves so much power. ... Now the house is cool and it actually uses less power"
"Also they have inverter compressors, so they can slow the compressor down to save energy when just maintaining temperature, instead of just off and on like regular compressors, it makes for less temperature swings between cycles as well."
"They use a variable speed DC inverter-compressor which only runs as fast as it needs to, also quieter than most."

"I haven't had to drain it since I got it; apparently it uses some kind of evaporation technology or yada yada."
"the Midea has a drain pump to pump the condensate out which is especially important in the heating mode, specially if it is going to go into a defrost."
"I have a hose and bucket and it’s been completely dry. Running almost every night for past 2-3months"

"Nach zwei Jahren sind die Schläuche für das Kondenswasser einfach zerbröselt. ... Nun läuft überall Wasser aus."
"one fills up with condensation and has to be drained every 15 minutes. ... I ended up having to jury rig a constant drain hose to it and it works fine but I’ve never had to do that with a portable before."
"Unfortunately did not install mine until after the Amazon return window ended and I had collapsed the box. I had emails with them back and forth about the smell, assuming that it was covered under the warranty. They were not very helpful. In fact they were very dismissive and told me to get someone to clean it (almost as expensive as the air conditioner) or clean it myself (which I believe would void the warranty) so I used the wick trick to drain water from the a/c and purchased an extended warranty. ... I don't understand why they would have created an AC that didn't drain. ... My brother has two of them, one of which is full of mold"

"Even the Midea dual hose units have this issue, just to a lesser degree. They are NOT sealed all that well and have gaps everywhere. ... There is definitely still some negative pressure, even with the Midea dual hose units. A slightly cracked open door will swing inwards by itself when the AC is turned on. ... I have a Midea unit and I know exactly what you're talking about. There is a small gap from the bottom chamber to the top chamber, and due to the pressure difference, the airflow reverses in that region. I opened up the unit and sealed it with foam to remove this problem. ... These things are not sealed very well and have gaps everywhere. There's also gaps on the bottom of the unit and around the drain hoses. ... The evaporator is also not completely separated from the condenser on the inside, so even if you seal all the exterior leaks, there is still some inefficiency."
"fait rentrer de la poussière et odeur l’air rentre de partout"
"Because, if you use this and you're exhausting air.... It is basically sucking air out of the van, creating negative pressure. So the van needs air, so the negative pressure pulls air from around the window or wherever air can enter. So warm humid outside air will be pulled in."

"when the inverter kicks on it really is quite the kick. ... It's also a bit bassy while it's spooling up. ... If you are a light sleeper it will wake you up."
"Does anyone know if it's typical for the Midea 12,000 BTU DUO Portable Air Conditioner to make this high pitched noise? ... The high pitched sound mine makes completely overshadows the fan sound on low setting and is still audible when the fan is on high even ~20' away and 2 days later. ... You don't hear the high pitched, almost cicada like sound? It's the most audible toward the beginning of the video. ... If the noise wasn't so high pitched I might have been able to deal with it."
"makes a terrible high frequency sound"

"If you have a small room you aren't going to want 12k anyway. It's not going to remove the humidity effectively... the room will feel cool but clammy and uncomfortable."
"one fills up with condensation and has to be drained every 15 minutes. ... I ended up having to jury rig a constant drain hose to it and it works fine but I’ve never had to do that with a portable before."
"Had a second Midea like the one you linked last summer and the Dry function didn't work."
Just bought the Midea Duo dual hose portable AC, it's so much better than the single hose I originally had. I live in central texas, so it's been hot as balls. Even with the rv ac on and the previous portable unit , I could swear that it was almost as though hot air was coming in from every nook amd cranny.
r/RVLiving • Does anyone use a portable AC instead of the AC mounted in the ceiling? ->I got this same unit for the same price, but mine has this constant rattle sound. Does anyone have any experience with this and have a way to fix it? I'd rather not return it because frankly it was a huge pain in the ass to get home.
r/AirConditioners • Midea portable AC at Costco $350, is it good? ->Check Slickdeals, I recently bought a refurbished 12000BTU Midea for $200. I live in California, currently 95F, and for an uninsulated garage of that size, you'd want at least a 12000BTU Midea if not the 14000BTU. There's currently a 18500BTU mini split on sale for $550 that be optimal.
r/AirConditioners • Looking for Advice: Portable AC with Heat Pump for Garage – Which One to Pick & How to Vent? ->Got the same one from costco and makes gaming in my upstairs office cool during the hottest days of summer! And no water drain!!!
r/AirConditioners • Next generation Portable AC units are pretty awesome ->Get a 2 hose portable or a Midea with it's 2 in 1 hose system. 1 hose models are sold in America 'because installing 2 hoses is too hard for that market to figure out'. They are the single dumbest invention in the history of inventions, blowing out the very air you are trying to cool. Buy an inverter model, and just spend the money on the Midea.
r/AirConditioners • Portable Air Conditioner Recommendations ->I just bought one ironically. I have a 3-car garage that faces the afternoon sun. Bought a 12000BTU AC from Costco and it can’t really keep up, but does a good enough job bringing it down to around 82f. The problem is that it’s drawing 14A and I have only one circuit to my garage so bigger is not an option without doing some electrical work
r/orlando • Anyone have a portable AC in their garage? ->You're very welcome, and I don't mind at all. We've got 2 of the Midea duo, model MAP14, 14000 btu units.( The actual working btu, called SACC btu are 12000) they are dual hose units, but use a hose in hose design, so not as clunky as 2 separate hoses. Also they have inverter compressors, so they can slow the compressor down to save energy when just maintaining temperature, instead of just off and on like regular compressors, it makes for less temperature swings between cycles as well. The important thing is, whatever brand you choose, it needs to be dual hose. The single hose models we've tried in the past caused so much negative pressure in the house that the humidity went sky high, along with the electric bill, and they didn't cool very well. (Most single hose units the SACC btu are around half of the listed regular btu, due to all the losses from negative pressure). The 2 duo models cool our entire 1000 square foot house, and are pretty energy efficient, better than some of the cheaper window units (some, not all, it is possible to get window units with higher efficiency). Dual hose with an inverter compressor is the best you can do for performance and efficiency, short of getting an inverter window unit. I beleive you can get the same model from Midea branded by Toshiba, and one of the Whynter models, just look for the big oval hose in hose exhaust, instead of the 2 small round hoses. There are a couple versions, some with heat pump feature. We didn't get the version with heat, as our house has electric heat and wood heat already, and the heat pump feature only works down to 40 degrees, so we didn't consider it useful enough for the extra price. Also, possibly not useful information, but we are happier with our portables than the window units they replaced. We went to window units after being dissapointed with single hose portables, and were never quite happy with them. Too much trouble to take in and out of the windows, heavy to lift and carry, have to get the tilt right or they leak, crummy accordion side panels that let in bugs and drafts unless you tape over them, the outside part gets full of dirt and crud over time, and they sometimes get mold or mildew in them, especially if the back has got dirty and hasn't been hosed out. All around total pain. Much easier to wheel a portable out of the closet and have it set up in 5 minutes, then at the end of the summer have it removed in 5 minutes, drain the unit from the rear plug, and wheel it back to the closet.
r/AirConditioners • Question about foam on windows for portable air conditioners ->350? Shit this unit was like 450 at my Costco. Returned for a swamp cooler, its colorado so swamp cooler works wonders.
r/AirConditioners • Midea portable AC at Costco $350, is it good? ->Dual or concentric hose models are the best bet. Inverter is good for noise. I have a midea inverter, with concentric hose that is great
r/DIY • Portable Air Conditioner ->I have it in my living room right now with vaulted ceilings. Keeps it 72 at 100 degrees outside so far
