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

Better but harder to install.

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?

Can I add another evaporator to the condenser to control another zone?

this one lets you keep your window view and is also quiet

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.

what if my window is wider than the unit and it slides side to side to open?

OP: I've done multiple installs of 220v mini-splits, but what makes this unit "non-DIY" as you described?

You need to evacuate the line set and indoor unit before opening the valves. Also you need a quality flaring tool for the line set connections.

You've installed these? Or DIY types?

Quote from misterdix :
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 quite true. Not all mini split systems are heat pumps. I've installed many cooling only systems

As an HVAC tech I'm pretty impressed..

As an HVAC tech, did you look it over, send it a bill for $60, and recommend that it contact sales because the unit can't serviced and therefore needs to be replaced?

Just like any window unit is not serviceable but just the noise reduction is a huge plus

Buy a multi head unit. Just be aware that the line sets are not very long and may require extensions. It may be better to get two units with 2 heads... A little insurance against a malfunction and having nothing at all....

Speak with a company that installs Mitsubishi, the system you want needs to be installed professionally

Does anyone know if they have something like this for a side sliding window? Need one for a bonus room and only have side sliding windows.

Width is adjustable, but the side slide might be an issue. I saw someone diy it with a sheet of plexiglass recently. I have no clue where I came across it though.

I just bought it. 12000 btu one is struggling to cool a 150 sq ft room in 90 degree weather in northeast USA

Something is wrong then. That size unit is more than large enough for a 150sq/ft room.

Anyone know what you can roughly expect to see in charges for the HVAC or electrical work on this?
