Is this better than the portable or?
The window unit is significantly more efficient than the portable, so it will save you money. I would go window unit if you have the option. A lot of HOAs and condos have rules against window units, so in that case you have to go portable.

For the most part these workm wonderfully and they run really quiet. I got a few for myself and friends and family from Amazon Warehouse for around 180-250. I had an issue twice where when I tried to start it for the first time of a season the condenser just wouldnt work and it kept giving off errors. Midea's support was really quick and easy to issue me a refund check.

I'm literally going to Costco in about an hour to pick up an AC and have been debating between this Midea and this Hisense one: https://www.costco.com/p/-/hisens...?langId=-1

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?
These are new and therefore have an updated drain plug installed.
The refurb ones, like the one I have, just included the new plugs to install myself.
It's just a little rubber plug that has to be replaced every month or so. You can check youtube if you want to see what they look like.

I have a question for you guys. I live in an old apartment that runs all electricity on one circuit breaker. So I cannot have too many appliances run at once. Currently I have the 8000 BTU Midea U shape and another 8k btu Frigidaire that I need to replace. I wonder if I get the Midea 12000 btu would it draw too much electricity and causing the circuit to break or would it only draw enough to cool the same room where the 8000 is now? This place is so bad that I can't have a Toaster, Microwave and blow drier running at once. So I'm afraid to increase the BTU from the current 8000 to a 12000. Any enlightenment is appreciated.
It tries to draw what it needs and has no way of knowing the capacity of your circuit, so if it exceeds the capacity, it will trip the breaker. Most of the time, the unit is drawing well below its rating, so if the 8,000 works the 12,000 will probably be OK (it would have been helpful if you posted the size of the single breaker). This is Costco, so if it doesn't work out, you can always return it.
FWIW, a toaster, blower dryer, and microwave are all high wattage devices. A toaster and microwave running simultaneously on the same circuit in a modern home will probably trip the breaker.

We've had both the Midea and the HiSense ones. We loved the several Midea ones we had, but they got recalled for the mold issue after we'd used them for about 3 years. The recall $$ more than covered the HiSense replacement. So far, the HiSense has also been really great. It blows as cold as the Midea, and since both are inverter tech, both are really very quiet. I've got to assume Midea has figured out the challenges with mold now, so the biggest difference between the two is the design. For me, the HiSense has been a much improved overall experience.
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.

Is this the one you have? It's their 12000 window one and is heavier than this Midea one (63lb vs 59lb)

Depends on how many they have left over. A Midea humidifier went for some great prices when they were trying to clear them out last year. This AC could probably get some great clearance prices... but only if they don't sell out first. My crystal ball broke unfortunately, so who knows if they will sell out of have a lot left over.

Hard to know without knowing the 8K units draw. Like if it's older or not an inverter unit then the 12k may pull similar wattage.

From looking online it seems like when the room is to temp, this should only pull 2-600 watts of electricity (your microwave is probably 1500-1800), instead of it's max of about 1200 watts. However if the room is hot or it isn't keeping up, it would possibly pull up to 1200 watts.

I think the 12000 can draw upwards of 1000 watts so that's really pushing it on one circuit. I have a small bedroom with lots of electronics and I didn't want to push the power too much either so I bought the smallest 6000 BTU unit from Amazon and that seems to max out around 500 watts but often it pulls lower (right now it's pulling about 240 watts but we're not at the peak of summer yet). The 6000 unit is not as good a deal as this 12000 BTU unit but if you are power constricted then I would consider it.

If I need one for this summer, do you think I should wait further or is $299 a good price? I don't have a lot of storage space so waiting is better if it gets cheaper.
If you need one then buy now and keep your receipt. If price drops later then you can buy another and return with old receipt if Costco won't price match.

The cost will vary greatly depending on temps but this is one of the more efficient window ACs you can buy.
