I've installed two of these exact units, and I wouldn't recommend them to anyone.

The main issue that I have with them is that their temperature control/regulation is messed up and the company won't do anything about it in terms of warranty support. If I set one to heat mode and set the temperature setting to a given temp like 72 degrees, the heat starts blasting, and continues heating up until the room is well over 100; it NEVER stops when it's on heating mode-- whether it's set to a temperature the standard way, or with the "follow me" mode on the remote.

When it's in A/C mode or Auto (which uses either A/C or heat as needed) the temperature regulation is extremely poor, when set to 72, the room will vary between 60 and 80.

There are also various more minor issues: the manual contains multiple errors, such as the hole cutout template is wrong for this model etc etc, the wiring diagram was wrong in the manual, and the wiring terminal label sticker was missing from both of my outdoor condensor units. All of these things just point to poor english language technical support from the company.

They don't stand by offering any meaningful warranty support to licensed contractors, and they openly state that homeowners/handyman installers won't get warranty support at all.
After a couple phone calls or emails, they promise to have their tech guys get back in touch, but you never hear from them again.

In the interest of fairness, there are several pros for these models though:
-These units are pretty easy to install (other than relatively minor issues with the manual and wiring diagrams) Also if you're not experience with cutting and brazing the refrigerant lines, then you'll likely wind up with an unsightly coil of extra line somewhere.
-They are QUIET. I don't have a decibel meter, but they are drastically quieter than any window unit or household central A/C that I have heard
- They are quite efficient compared to central A/C units or window/portable units

I hoped that these units could be an economical alternative to higher end brands, but while their mechanical performance is apparently quite good; they are quiet, powerful, and efficient-- the numerous electronic issues make this models a poor choice IME

I have 3 of these 2x12kbtu and 1x8kbtu covering a 1500 square foot house. It really only needs two 12kbtus but my house is split into sections. Watch the installation videos because the instructions are horrible. They are quiet, they are efficient.
you have 1 in each bedroom? i assume a 1500 home is 3/2.

Quote from Ross1987 :
I just installed an 8000 BTU Midea U today in my own apartment. It's truly surprisingly quiet, even with super low quality single pane American apartment windows. My girlfriend was really pretty impressed.

There are some "teardowns" on YouTube, seems like they went for higher quality components across the board and each bit contributes to lower noise. Whatever they did, I'm very very happy with the noise level.

It's still a fan, but on par with a coway mighty about halfway between their setting "2" and "3" (actually rather closer to the 2 but still also definitely rather louder) I only really hear the fan noise from the Midea and a quiet non-rhythmic ticking that I assume is the coolant or maybe the compressor.

The other benefit is that the Midea is 120V whereas almost all mini splits are 240V. That's not possible for me to wire up in a rental.
Was it hard to DIY?

As others have said.... not a heat pump. That being said.... one of the best window A/C's I've ever used. Sitting in front of one right now.

Just installed 3 of these Midea's a few days ago. Pretty easy to install though not as simple as a basic window A/C. First one took maybe two hours as instruction manual/video wasn't too clear for my type of window (so had to redo some parts), last one took less than 30 minutes.

How does this compare with portable one?

Portable Ac are very insufficient they cost way more to run and are not accurate. Ductless is way better choice and will cool and heat better and more efficiently it just is a little harder to install but once installed it's permanent and it looks nicer

Who did the installation? You're probably low on freon r410a and need to charge it up

Quote from DealBoi4Life :
Applause Pretty cool. Window units should've been designed like this all along.

But the window is still open a few inches and the compressor is right on the other side of the glass, so I'm curious as to how much quieter they are than a traditional window unit.

A mini split keeps the window closed and the compressor even further away and will give the occupant the quietest performance. And some mini splits, including this one, can heat via heat pump.

I have the 10,000 BTU Midea split inverter AC. It's absolutely worth it. It is so much quieter than a regular unit. And with the window closed all but 2 or 3 inches, it's more secure as well. I'm guessing it's the inverter which makes it slowly spool up and down rather than the big "clunk" you hear with traditional window units when the compressor kicks in. I bought one for the living room a few months ago and like it so much I will replace the bedroom one with a 8,000 Midea unit soon. Another benefit I didn't expect, it's a LOT quieter on the outside as well. So if you're sitting in the yard, you don't hear the constant droning of the AC units. Overall a winner, assuming it lasts for a while.

Now, I've had units like the mini split in Europe, and they are WAY better. You can mount them near the ceiling and they are virtually silent with the whole compressor unit being somewhere outside. And as a bonus you can heat a little as well. I would prefer a mini split over the Midea, but it's not practical for me. The Midea is the next best choice I guess.

These units are good. I bought the DIY version from Costco last year in April. I didn't want to be stuck at home all summer with NO AC.

Do you mean MrCool or Midea? Any other info appreciated

Is there anywhere to buy open box full house air conditioner units? Then just pay for install? I remember a post about a year or two ago that had like $3000-5000 units for about a grand.

Designed to heat or cool 250 square foot room
If I have a 270sqft room with a 3090, 9900k, LG OLED, and a few monitors, would this be enough? Genuine question, not bragging. I have a Whytner ARC-14S, 14,000 BTU portable, but it was the stinkin' pre-DOE ASHRAE model that is *really* 9,200 BTU.. It flooded my entire living room and never actually cooled the space adequately for $500+. The main product page still doesn't list the DOE/SACC info and it certainly never will cool 500sqft.

If anyone has any better options please let me know! Always looking for good deals with saving for college for a toddler and wanting to not roast to death in the south.

Quote from thrillhov :
So much quieter!

Admittedly, it does not have a heat pump, so it is not a perfect replacement for OP's deal.
I just bought my second Midea u-shaped 8K BTU a/c after having one for a year.
I set up a home office for WFH, and I can comfortably have zoom meetings 3' away from this thing and no one would know.

Without a doubt the best window A/C I've ever owned. I even put the kill-a-watt on it to compare to my old model and because of the inverter tech, it is pulling half the electricity.

the A/C mode is quieter than my window fans and the "Fan" mode is so quiet you'd forget it's on.
The smart features are really well implemented too.
I just want to add to this discussion about the u shaped midea. There are two features which I find to be a fatal flaw. 1) it had some algorithm that determines how much compresssor to use based on the house and outside temp. If it decides that 25% capacity is all that is needed to reach the temp you set, you cannot override it. So the air you get will be cool but not cold.

2) the compressor is also tied into the fan speed. So if you want the fan speed on very low due to needing quiet, the compressor will never operate at more than 20-30% capacity meaning your 12k btu unit will be putting out the equivalent cooling of a 5k btu unit.

The ONLY time I've been able to get the compressor to operate at the full btu capacity (based on cooling power and kill a watt data is when it's 100 degrees outside and 80 inside.
