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.

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.

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.

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

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.

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

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.

Midea or clones there of. The model with the big giant oval hose is really a 2 hose model. If you have electric heat that you pay for, get the heat pump model instead. It absolutely cranks out the warm down to -5C. Then rely on your electric heat for the coldest days.

The first rule of portable air conditioners is get a 2 hose model (or the Midea with the giant oval hose that is really 2 hoses. 1 hose hose models are an america only thing. They blow out the very air you are trying to cool. The only reason they exist is 'stupid people are confused by 2 hoses'. 2 hoses balance the pressure and use outside air to cool the condenser. They are the correct choice.

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

I have 2 of them for the better part of 7 years. A 12k btu and 9k btu. Midea and Defy. One in my bedroom (4m x 3m) and one as a roaming AC. They work very well. I don't mind the noise. I pretend I'm on a flight somewhere. I won't do wall AC because I'm renting and my landlord is cheap and won't pay. This will suffice. It's better than nothing. I sleep like a baby.

Never a single hose, dual hose inverter unit if it must be portable (Inverter units can be quieter and use less energy because they don't just blow at full power unless needed) I would get a window unit if you can. make sure you get the correct size unit. My midea doesn't leak, but I don't think that's actually a wide scale issue lol.
