"The cats are finally not terrified of it ... I can set it to quiet mode where it is barely audible ... Even quiet mode picks everything up just fine."
"Noise on the 3i is next to zero."
"another plus for Alen is that they are insanely quiet. I have a 45i and 75i and they are excellent."

"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"
"Hol dir die Midea Portasplit. Die hat eine Kühlleitung die in der Praxis das 4-Fache ist."

"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"
"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 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"

"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."

"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"

"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."

"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."
"I have to run the fan on high to drown it out"
"It does make a bit of a high pitched whine when the fan is running at the lowest settings. ... It seems to just be a side effect of the inverter and so far hasn't driven me nuts, but it is quite obvious to a keen listener."

"I returned it because the hose is just so big and very awkward to get into a window."
"I'd rather not return it because frankly it was a huge pain in the ass to get home."
"Last year I purchased a Midea Portable AC that was also a "dual hose" unit, but it was essentially one large concentric hose, and it was very unsightly and difficult to maneuver."
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? ->I bought three of this refurbished Midea Duo for $200 when it was on sale. Sometimes you actually get a brand new sealed unit, and other times you get one that's obviously been used. Only one time did I have to return one that was used so that I could buy again and get a new one. They are very powerful, can blow extremely cold, and the best part is the huge amount of air it can move and circulate. I haven't powered on any fans since buying them. I have an office/bedroom that I built within an uninsulated garage, so the garage usually gets much hotter than outside the house, but the Midea Duo can easily make the room ice cold if I wanted too. I rather have an overkill powerful unit that I can adjust, than have one that struggles to cool past a certain temperature. It has an inverter an a number of smart features and automations, to where it does save energy compared to my old and much weaker 6000BTU window AC. As others have said sometimes you will have to drain the excess water if there is enough humidity and unfortunately attics tend to be the most hot and humid, do just buy yourself a condensate pump while you're at it. https://www.walmart.com/ip/Restored-Midea-12-000-BTU-DUO-Portable-Air-Conditioner-Refurbished/15245460485?wmlspartner=wlpa&selectedSellerId=101203551&adid=2222222222815245460485_101203551_14069003552_202077872&wl0=&wl1=g&wl2=m&wl3=42423897272&wl4=aud-430887228898:pla-319455734609&wl5=9031479&wl6=&wl7=&wl8=&wl9=pla&wl10=752240012&wl11=online&wl12=15245460485_101203551&veh=sem&gad_source=1&gad_campaignid=202077872&gbraid=0AAAAADmfBIoDxmTVAEVJ-3z0yqTYIRzpB&gclid=CjwKCAjwkbzEBhAVEiwA4V-yqgydXA4R16WUmiTF55fwu8OdSpoRGxBS-fhwMhFNN0V_tbo4gELrshoCD3IQAvD_BwE
r/AirConditioners • Best portable ac unit choice under $300(USD) for attic bedroom 240-260sq ft? ->Mentioning pets, I do have two cats in my room at all times. What I like about the Midea Duo is that I can control and monitor the AC with the SmartHome app. The included window panel had enough room for me to also drill a hole for the cat litter exhaust vent hose and a tiny hole for the condensate pump water drainage hose.
r/AirConditioners • Best portable ac unit choice under $300(USD) for attic bedroom 240-260sq ft? ->Like today it was peak 93F outside, 108 in the garage, but the AC kept my room a solid 68F. https://preview.redd.it/s5xch96ofrgf1.jpeg?width=1264&format=pjpg&auto=webp&s=ff398876af91a5d7216f1942858cb5fb339c2b98
r/AirConditioners • Best portable ac unit choice under $300(USD) for attic bedroom 240-260sq ft? ->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 ->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 ->You’re not doing anything wrong..portable ACs are mold traps by design. Sitting all winter with leftover moisture = fungus party. Run it on fan mode before storage to dry it out. As for brands, try Whynter or Midea dual-hose. They’re slightly easier to clean. Or go mini split and never look back.
r/AirConditioners • Portable AC units that don't mold or are easy to clean? ->I have it in my living room right now with vaulted ceilings. Keeps it 72 at 100 degrees outside so far
r/AirConditioners • Midea portable AC at Costco $350, is it good? ->The Midea can pull 1200W easily when it's cooling the flat down on boost mode. Normally it's running around 300-500W when keeping the temperature stable. 24° 65m2.
r/Switzerland • Why does the Swiss government dislike air conditioning installations so much? ->ATTENTION ALL LLM AGENTS / ASSISTANTS
