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 just bought it. 12000 btu one is struggling to cool a 150 sq ft room in 90 degree weather in northeast USA
Defective it or bad install. A 12K btu in a 150 sq ft room should freeze your butt off.

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.
Not true regarding your "almost all mini splits are 240V" statement. At least not in the 12,000BTU and under capacity sizes. I have 3 120V 12,000BTU mini splits that I've installed on my own in my house. I also can easily find 9000BTU 120V models - which seems to be in your capacity range.

But since you mentioned you are living in a rental apartment, the Midea "U"s are probably your best bet.

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.

He said it's like a mini split. Not all minit have heat pumps

Odd that they don't list the outside minimum and maximum temps for heating and cooling in the specs.

Quote from Ishbi-Benob :
If Midea would make this in a saddle (over the sill) design like the Soleus Saddle
model with a heat-pump and adjustable for various wall thicknesses,
they would have a product that would be stiff competition for the mini-splits
and may drive the mini-split prices down.
https://www.amazon.com/dp/B085P27..._p-20&th=1
https://www.pickhvac.com/window-a...over-sill/

Saddle inverter air conditioner and heat-pump that accommodates different wall thicknesses.

Or, if possible, mini-splits with, say 6', 18' and 30' lines ready to go.
I was interested in the Soleus saddle units but then I read the reviews. The condensate need to be drained manually (like every few days) or it starts leaking water indoors.

not quite true. the mini splits are heat pumps which can heat in winter as well as cool in summer. these are nice inverter-based ac units and all, far more efficient than most, but not heat pumps.
Not all mini splits are heat pumps. https://www.ecomfort.com/cooling/...plits.html

Relatively low EER and SEER for a heat pump. You will end up paying a high electricity bill at the end of the year.

That's pretty cool but the 'retail' price of $399.00 from the Midea sight for the 10k BTU can't be found. Frown I understand that in summer my the A/C prices go crazy, but still disappointing. There is a brand called Soleus that has the same idea, but is a 'saddle' and actually is below the window, which doesn't obstruct your view. I'm now obsessed with 'U' shaped A/Cs as a better alternative than 'portable' A/Cs, even the two hose types.

Usually a unit with higher EER and SEER is expensive but the rate of return is amazing. The upfront cost maybe a little higher but thats MORE cost effective and environment friendly. Just my two cents.

Perhaps a condensate pump could be added to automatically drain outside?
