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

Some installer guy quoted me like $13000. Thanks but no thanks

$6000 for me but I had to buy my own system and the guy was unlicensed. He said he would run each of the minisplit lines through the attic. But he cautioned it would need a pump to make sure there was no flooding/dripping.

I would like 4 mini split heads, one in each bedroom with its own individual room control, with the split unit outside. What do you guys recommend for that setup?

Mr. Who?
Really good heat pumps will heat a home even when the temp outdoors is below zero. Wonder where this one rates.

Quote from dcmanryan :
As an HVAC commercial technician the one year warranty on the compressor says it all. The standard now is 10 year on most companies that actually care what they're selling you. The price on this is dirt cheap and I suspect you'll get what you pay for but I've never installed or worked on this brand I'll admit. Seeing their warranty I'd never buy it either and I'd especially never buy it if I had to pay someone to install it. I'd personally just live with a window unit if I wasn't interested in upgrading to central air.

Great advice. Costco also seems to have dropped this brand. It was on their site last 2 or 3 years but not this season.

I almost jumped on some of the diy units but couldn't get over the hidden bad reviews.

For those of you who've had these installed, how much did it cost for just one unit in the bedroom?

This is what I have and they work great. Quite enough to have in the living room. Easiest window AC I have ever installed.

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
mini-split or this window ac unit? decisions decisions

thenewyorkgodI would stay away from these and just get an LG inverter AC. The U shape is mostly a gimmick and has many downsides. The install is very cumbersome and there are so many cracks and gaps you need to fill - you will never get a good air seal

1. The U shape is good in theory, but the install is highly complex, nothing like they described and will leave many air gaps that require foam, filler, tape and other crude methods. Is it worth being able to close the window 80% and block out 50% of the noise? I would say probably not, espcially since when you implement the safety screws and tilt prevention mechanisms, you can't open and close the window anyway.
2. I am highly suspicious of the BTU claims. Firstly, the 8, 10 and 12K unites are all the same dimension and weigh nearly the same. I have never encountered that with a window AC before. I got the 12k unit and noticed it was not cooling my 12-16 room anywhere near as quick, or as well as my old 8k window unit. I hooked up a meter between the plug and the wall and to my shock, the unit never draws more than 600-650 watts, even when set to MAX, eco off, and temp to 60. That is more in line with a 6-8kbtu unit. A 12k BTU unit should be pulling 1000-1200 watts. I am not a conpiracy person but I think they created a single 8k unit and just slapped 8, 10 and 12k btu stickers on them.
3. Another major flaw is that the fan speed is directly tied in to the compressor power level. A high fan speed will have the compressor at full power, blowing very cold air. A low fan speed will reduce the compressor to it's weakest stage, pulling 150 watts and blowing air that i could barely describe as cold. Customer service claims this is due to an algorithm that helps the unit decide how much power to send to the compressor based on fan speed. Well guess what - if I want a low fan speed, but want the air to come out ice cold, I should have that ability, like every other window AC on the plan. As a result, if the room is hot and you want to cool it down and keep it cool, your only option is to have the fan at high speed, and thus loosing the "quiet" claim that made this product so attractive.

Summary:
I would not recommend this for anyone who is attracted to it based on the U shape. Your best bet is to go with a standard window unit. If you are interested in a money saving option, there are a few other inverter technology window AC's out there that will allow the compressor to run at less than full power, which will reduce the noise and power draw, but of course, sacrificing cooling power. At the end of the time, there is no cheating physics. I have removed this unit from the window and put my old trust mechanical 9k btu unit back in the window. The room is much more consistently cool and I will survive with the higher noise, content in the fact that my window is better sealed
I find the U-shape is great, and leaves as many gaps as my regular window unit. Well, that is if you consider the cheesy plastic sliders on the side of regular window units a proper cover. I do not. Someone could just punch a fist through those. Harder to do with a double glass window.

My 10,000 unit has a EER of 15, which is very efficient. If you do the math, my unit should pull 5.79 amps (665 watts) at most which is pretty low. I see mine regularly pulling up to 5.1 amps (586 watts), and that's with eco on and nothing really maxed out. Your 12,000 unit, assuming it also has a EER of 15, should pull no more than 6.95 amps at the most. That's around 800 watts. So yes, it's weird that your 12 unit pulls as much as my 10. I wouldn't be surprised that you may be right, they are all the same, but software limited. That would certainly save them some money but wouldn't necessarily be a bad thing.

When I switch my A/C fan from low to medium let's say, I hear it spool up, but it only uses a few watts more. To me that means there's only a fan spinning faster, not necessarily the compressor? I'm not familiar with all that, but that's what I see. Could be wrong here.

Either way, I love ours, and will probably get the 8,000 for the bedroom.

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 agree. Got my Media 8k during their crowd funding. Should have ordered 2.

You got this? How well does it work and what size can 10k cover?
I have this. I have the 12000 BTU version.

It's 90 here today and it has kept my entire downstairs cool. It's super quiet.

Excellent unit. More efficient than the previous window unit I had, and much quieter.



I got it from my local Menards.

This is a great design! With any window unit, make sure you block the top of the window. I can't tell you how many times we (HVAC techs) saw no foam, cloth or tape to keep air from coming in on double hung windows that have window based units. Even roll along units are subject to this problem when windows are open more than a few inches.
