Midea 12,000 BTU Smart Inverter Air Conditioner Window Unit with Heat and Dehumidifier – Cools up to 550 Sq. Ft., Energy Star Rated, Quiet Operation, Electronic Controls, Remote Control, White

This is not the top-rated U-shaped Midea model, which is in low supply, one of which I bought in 2023.(So I now have both the U-shaped and the traditionally shaped 12,000 BTU Midea AC window units.)Background: 2 years ago I installed the U-shaped model in the kitchen of our 1910 Sears & Roebuck kit house, a fixer upper, while we lived on just the first floor (600 sqft), and it kept the entire first floor ~72 or cooler (depending on setting) nearly all the time. May have been a day or two it struggled to keep up, but we felt no need for a second unit for the 1st floor. It was SUPER quiet; as quiet as the fridge or ceiling fan, unless cranked up, and most of the sound was the fan. So the U-shaped model was what I wanted for the second floor, but couldn't find it anywhere (within $300 of what I paid before).We finally moved into the second floor bedrooms (last fall), so (mid May) we bought this traditional window box unit (not U-shape), but same capacity hoping to similarly service the 600 sqft second floor. (Yes the second floor was carefully reinsulated during the re-do, and it has efficient vinyl clad windows and thermal blinds. Only about 16' of insulation above ceiling, will see if we need more for summer, but it was fine for winter.) This unit included the heat inverter for heating at temps >41 degrees. It WAS significantly simpler & easier to install than the U-shape as there was no need for an external bracket and bracing, and less complex weather stripping. In retrospect, this model may have been better for the second floor since we could easily do the entire installation from the inside of the house. Took a second pair of hands for the 30 seconds of setting the unit in place in the opening (I'm 71).While this 12,000 BTU unit is perhaps not quite as quiet as the U-shaped 12,000 unit, it is comfortably quiet. We still haven't hit the peak heat of summer, but it seems as though it will keep the entire upstairs sleep-ably cool at night at least so long as the doors are left open. For now it cools fine in the heat of the day up to mid 80's and perhaps more (it hasn't yet exceeded 86 outside).We installed the unit in the SSE facing largest room, and it kicks on about when I wake and morning sun starts to warm my room, and during the day is keeping the upstairs from ever getting within 15 degrees of the daytime summer temps upstairs the past two summers. The heat inverter was nice to use without turning on the furnace for a few nights this past week where it dropped from 80's back to 40's in Madison WI. You many want to supplement the adhesive weather stripping for the two slide out panels, where they abut the inside of the window opening and leave a fine crack (I haven't yet sealed it; the crack is too fine for insects so far), and at a couple places under the unit that did need the provided weather-stripping. I think this is a good buy, assuming it endures.These two units (<$1000 total, 2 hours installation total) appear to suffice in place of the 3 quotes of $10,000 - $15,000 for contractor installed central air in this old radiant hot water heated house with no prior air duct engineering. (Can send my kid to school another year instead!)

I bought this since I really liked the functionality of a previous Midea unit I bought for my shop, but didn't care for the u-shape style.This one is 8000 BTU, and also has the heating function. It is basically a heat pump in a regular square window unit form factor. I bought it to help cool the bedroom, and heat function was just a nice "bonus" that I didn't plan on using. I installed it early April, and the temps dropped the next day. I will say that the heat function works very well, and while the literature says 41 degrees F (5 degrees C) is the minimum outdoor operating temperature, it seemed to work down into the upper 30s (around 2 to 3 degrees C) on a couple nights.In the app, this model actually shows up as a "split unit" so you know it's a real heat pump.ProsCold when you want itWarm when you want it (within reason)Much quieter than the generic "on/off" style window unit it replaced (this one is inverter driven)Scheduling and long distance operation via Wi-Fi and the app is pretty easyIncluded remote works wellThey include locking screws and insulating tape for installation. The top groove and side blocking pieces are included, but you have to attach themConsIf you have sensitive hearing, you'll hear the high pitched whine from the inverter systemMy LED lights on the same circuit as the AC flicker in a slightly annoying wayIn auto heat/cool mode, the "dead zone" AKA "hysteresis" is a bit too small. The system will switch between heat and cool a lot if the temperature is close to targetUnit was a bit wider than the old AC, and I had to get creative with the side blocking pieces and insulating tapeAt certain frequencies, you may get some vibration in the wall/window from the AC. I get it a bit, but it's usually while it's speeding up so it only lasts a few seconds. The manual states this happens due to "weak walls." I live in a double wide, so maybe?I'm really being a bit picky, because overall I'm totally satisfied with this unit! I like that it only runs as hard as it needs to, and the 8000 BTU size is great for a medium bedroom and bathroom combo. I strongly recommend it so far.Overall power draw is typically between 200 and 400 watts while running, it does seem to use a bit more power in heat mode and gets close to 500 watts at times (according to a KILL A WATT meter)Stand by is under 2 watts

Has a high CEER 13.3 efficiency rating. This is very good, means lower electricity cost to operate. Installation was straight forward and start up and testing very successful. The inverter technology used in construction of the compressor unit is impressive for a 12000 btu unit with heat pump. Truth in advertising was also impressive when describing the limitations of the heating portion of the unit. The heat pump portion of the unit is effective down to 41*F as any typical heat pump. Many advertisers overlook this. But during Spring and Fall with temperatures in this range the unit seems to perform excellently. The AC function of this unit also functions excellently. Controls are easy to use and convenient.
