My SO got this for our bedroom last year and I ended up getting the a Toshiba variant from Woot in May for my office. Very solid AC performance, but the remote controller works glitchy as hell at times, especially when trying to turn it on/off. The MSmarthome app is really glitchy too with shutting it on and off and scheduling basically works half the time unless you set it up with 24 hour time. Alexa integration is trash if you are not the primary account holder of the unit, but otherwise works. And finally, the temperature reading, from my unscientific tests, reads about 3-4 degrees lower than it really is, so an offset would be necessary if using it with home automation stuff. Agree with everything KevoD said too. I bought camper seal foam tape from Home Depot to augment the sealing (the default adhesive is super messy to remove), and it's worked great so far.

If you can deal with those first-world problems, highly recommended!

Bought this when it was posted last month and have enjoyed it so far. Cools great (temp goes as low as 60 degrees). Only two concessions are that it periodically gets kind of loud for 10-20 seconds during regular operation (without warning) which can be a bit annoying if you're on the phone, and the insulation where the hose attaches to the window bracket could be a little better to reduce exterior noise and air flowing in when the unit is off, but otherwise have no other complaints. I imagine the insulation issue is going to be universal for any portable AC, though.

It generates a lot of heat, that's for sure. It's nothing like a space heater. You can just imagine all of the heat that goes out the hose in A/C mode is reversed into the room. It will warm up a medium-sized room very quickly.

The downsides of the heat function are:

It only works if the temp outside is above 42 degrees. So depending on your climate this may only be useful for chilly spring and autumn days.
It generates a lot of condensate so you have to hook a hose up to the highest drain and empty the bucket every now and then.
When it's cold out, and the unit is not in use but still hooked up to the window, a lot of cold air is going to come in through the duct hose. This can also cause a lot of condensation to build up underneath the unit where the cold air pours out onto the floor. You really have to pull it out of the window and shut the window when it's not in use if it's cold outside.
Make sure you wrap the duct hose with the included sleeve if using heat mode, to prevent condensate from building on the duct hose.

Overall I would say it's good for chilly spring / autumn days where you need a little extra warmth but don't want to turn on the furnace, but not so useful for very cold days like in the dead of winter.

Guys, can anyone recommend any units that dont require window installation? do those even exist? thank you all!
A portable AC unit must vent to the outside through some means. Otherwise, you're just venting the heat back into the room and not cooling anything. Your only real option without venting is a swamp/evaporative cooler but those operate through a completely different cooling method.

Any issues with bugs? It doesnt look like the hose inlet on the window has any kind of screen to prevent bugs from being sucked in?

Also saw someone say they had to disconnect one of these in the winter due to cold air sitting in the hose and causing moisture issues?

I left my window screen on so while I'm sure the littlest of gnats can get through, I haven't noticed anything in the month I've used it.

I thought of the same thing, but after I saw the vent in person I realized I would need a bigger vent hole. Have you seen it in person?
Havent taken it out of the box yet. Waiting on Costco to match this new price.

Quote from NSXMK3 :
Maybe a silly question.. my windows are stupid short (18" wide?), the manual I found online said for windows 19" to 56" or something like that.. I assume I can still make it work on an 18" window (possibly with cutting if needed?) but interested in anyone who used it on a short window like that? Height is probably 30" but width is 18" and it opens vertically.

Also any idea on the hose length and just how sturdy it is? I have an older LG single hose and the hose will crack with almost any bending, so it needs to be held in one single spot.

Last question -- my LG hose needed to be wrapped with lots of insulation around the hose (the metallic wrap and tape) to prevent the exhaust heat from warming the room, would that be of any benefit to this type of model, or just run it as-is?
  1. No promises but it looks like an 18" window could work. I took some rough measurements and it seems the duct panel needs to be at least 16" to give the hole some sturdiness. The duct hole itself is about 13" wide. You'd have to do some cutting, but everybody does.
  2. The hose is very large and stiff. It doesn't really turn well. It's best to keep the unit as close to the window and the hose as straight as possible. There is some play in it, but don't expect miracles. The material seems sturdy.
  3. Just run it as is. The hose-in-hose design removes that problem. The outer hose itself is barely warm when running. The units that include the heat function (like this one) also include a sleeve that you slide down the duct hose, which also acts as an extra insulting barrier.

How bendy is the hose? Looking to use this for non standard install. We have a 100 yo house that had "sleeping porches' that have been enclosed at some point. Where there was once a door there is now a 6 or so foot window that sits just above a 12 inch high baseboard. I am wanting to remove the base board and run it through to the exterior (which has corresponding 12 inch trim). Don't want to have to have the unit far away from window to accommodate the hose if I can't run it straight down and out in a u shape. Any insight appreciated.
It's big and bulky and hulking and stiff. I can't quite envision what you're trying to do, but I think it might not work if you need a lot of flex.

It has questionable reviews, but FWIW I bought mine about a year ago and absolutely love it. Will be buying another soon for the future baby room. South-facing upstairs rooms get hot quick.
Same. I bought a Hisense dual hose a few years ago and it works pretty well, but its kind of loud and kicks on and off pretty frequently, even prior to reaching set temp and on days where it was 90 degrees +, would end up tripping the breaker multiple times a day, likely because of the constant initial power draw likely creating more heat.

I bought this Midea last year and have been loving it. Not too loud, even on high, but it doesn't often go to high regardless. I have it for cooling our downstairs, probably about 1000sqft and it does a damn good job. The variable fan speed is great, half the time its on, I don't even hear it. I think this is where the inverter technology really shines. I haven't had a breaker trip at all and the room this is in is also tied to half the circuits in the kitchen. I've ran the microwave, air fryer, and toaster while the AC was going (not all at once, just one at a time).

I don't use the remote, so can't speak on that--But all portable AC remotes seem cheap and janky, imo. Haven't used the wifi controls either, just because I have a distrust for apps from brands I never heard of.
Quote from BlueDancer :
I also have this unit from last year. Seeking advices how do you connect the drain hose and where to drain to? I used a plastic container but the drain bottom is too low and container is too tall.
Are you using it to dehumidify or cool? If you are using it to cool, you don't need a condensate line, it is evaporated with the exhaust. If you are using it to dehumidify, the person who responded to you probably has the best answer. I'd look in the manual but I think my wife tossed it the same week we got this unit. Been looking for over a year now.

I'd say removing in the winter is probably a good idea if you aren't using it. You'll just accumulate dust, dirt, bugs and if you get sideways rain, you will get standing water in the unit.

Unfortunately, it is the case. I've had it for a few years and tested it myself. The problem does not lie with the dual hose, it lies with the way they designed the compressor compartment. It's not sealed properly and allows interior air to be pulled into the compartment through the grills and then vented outside.

If you put the unit in a small room with the door closed and put your hand near the space under/around the door, you can feel a definite inflow of air coming in when the unit is in operation versus turned off. It's nowhere near as much as single hose units I've tried, but it's there.

If you search the Amazon reviews for this unit for the term "negative pressure", you'll find other people mentioning the same thing.
Did any of those reviewers do a fog machine test to see if that air is actually getting pulled outside? I'd try it, but I don't have a fog machine.

My thought would be that since the air is being condition, therefore taking up less space, so that pulls in more unconditioned air. But maybe my understanding of thermodynamics and air pressure are flawed. I only know what the weather guy/gal on the news tries to convey to me.

The vent is quite big for sliding window installation. It's about a football size 12" from one end to anther. The dual hose is not very bendy. The unit must be almost directly under the vent, not much room for flex.

Does this really run at 42dB? That's quieter than my U Window unit. How is that possible?
