there is only one problem and it's huge after awhile
the blower fan is nearly impossible to clean
I don't keep the AC in the bedroom window all year, so the process of install and pulling it is important. While both are somewhat heavy, the Midea one always felt like it would flex and collapse on itself when lifting it out of the window. The HiSense feels much more compact and rigid. I haven't checked, but it also seems smaller/lighter. My wife is really sensitive to light in the room when we sleep, and one challenge with the Midea one is that in order for the room blind to black out the room, it would have to slide behind the room side of the AC unit (in between the ac and the window). For the HiSense, this is not an issue since the blinds can come down to the top of the room side of the unit, and then the sides are blocked out with the included foam. We use a roller shade, so it was thin enough to fit between the AC and window on the Midea, but if we had other options like mini-blinds or slats, we would have had a lot of light in the room with the Midea.
Since we mostly keep the blinds down in our room, the other benefit of the HiSense is aesthetic - there is only a small footprint on the room side of the AC unit.
Again, this is not to say there is anything wrong with the Midea as long as they've fixed the mold. It was really great as well. In terms of function, they both seem to be pretty equal. The HiSense ones had several sales last year through Costco. As it is getting hotter, I wouldn't wait to get one, but if you get one Costco, be sure to watch out for a drop in price in the 30 days after since they will honor the price adjustment as long as you request during the time it is on sale and within 30 days of purchase.

This Midea 12,000 BTU smart inverter window air conditioner is praised for strong cooling, quiet operation, and efficient power use, with smart app energy tracking on some units. Installation is usually described as manageable, though the unit is heavy and may take two people, and it works well for bedrooms and other single rooms. The main cautions are the earlier mold recall history, occasional drain plug and energy reporting quirks, and possible breaker trips on crowded circuits. It is a solid fit when you want window AC performance without portable AC noise.
Common Questions (6)
Warehouse pricing is commonly reported around $299-$300, while online pricing is higher because of shipping. Several comments also mention past seasonal drops to about $199-$125, so the best price often comes later in the season or in-store.
Yes. It is repeatedly described as very quiet and more efficient than portable units because the compressor sits outside the window and it uses inverter tech. Several comments also note it can cool bedrooms and larger rooms effectively, though very hot rooms may make it run nearly nonstop.
The model number matches the recalled line, but the updated units are described as having a redesigned drain plug and being fixed after the recall. Some owners report years of use with the recall repair kit and no mold issues afterward.
When the room is already cool, it can draw roughly 200-600 watts, with peak draw around 1,000-1,200 watts when the room is hot or it is struggling to keep up. That makes it efficient for normal cycling, but it can still trip a weak or overloaded circuit.
Installation is generally described as manageable but heavy, often taking about an hour and sometimes needing two people to lift. The included instructions cover both lipped and non-lipped windows, and several people recommend following YouTube guides for the easiest setup.
Yes, if the circuit cannot handle its peak draw. It usually runs below its maximum, but comments note that older AFCI breakers or heavily loaded circuits can trip, while a dedicated or updated circuit often solves the problem.

Big plus - it's more quiet as the compressor is effectively outside the window. The foam does let a bit more noise than the window alone but it's still noticably more quiet than the portable one
Of course, the portable one is portable so depends on your needs.
The price drops as the cooling season progresses. I ordered a couple in the fall of last year for $199 each, so if you don't need one right now it might make sense to wait.

I'm using it to cool my master bedroom which isn't that big so high BTU isn't a concern for me. I was planning on picking up the Hisense since its more compact so the window doesn't have to be open as much and I can get more sunlight in. However, it is $20 more and it has less BTU than the Midea (8000 vs 12000) but that doesn't bother me.
My concern is that this Midea model has the same exact model number that was part of the huge recall last year. Someone mentioned here that the drain plug has been updated but does anyone know if that truly resolved the issue?
