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

We had this for several years in one of our rooms. It cooled the room well. However, it's frequency of resonance can make some glass, like ours, sing. It's like running your finger over a wine glass but at a much deeper rumble if a pitch. The sound is totally annoying. We had to place extra foam around it. to dampen the vibration.We also had to make some modification to the window frame so it would fit. Without the drainage running down our cedar siding. It was also harder to clean than our other units. We like in 80% humidity most of the year so we have to clean to keep down mold and mildew.This unit did not last any longer than it regular units. We will not be buying another u-shaped unit. However we would probably give the brand another try.

Placed in a sunroom that gets blast of afternoon western sun on large windows for 3.5 hours. Unit does a great job of keeping room nice and cool. Love the “Auto” feature that turns unit on and off to maintain set temperature.

12,000 BTU with heat. Does not blow cold air, cool air only. Box was opened from the bottom and unit had been delivered upside down due to box being opened from the tape seal being broken. It sat on my floor right side up for over a month after I brought it inside. This was supposed to be a new unit but it was not taped on the unit itself in the places my other unit was around the filter housing and vent opening. I was hoping to get help to install from acquaintances but couldn’t . I was able to get it set up by myself with a bit of a struggle.It only blows cool air ,not cold. Had it set to 74 on auto all night long , and when I woke up it was blowing HOT air and my living room was very hot, and was not set on heat, had I been able to install before 30 days I would have returned the unit. I’m not happy! Big disappointment.I had also ordered a U shaped same brand 10000 BTU and installed it in my bedroom. It’s whisper quiet and blows ice cold air , works great, best A/ C I’ve ever had, and I could not be more pleased with it.

So much quieter and more effective than the portable AC I was using! Worth every penny as I can hear the TV and sleep while the thing is still cooling!

The media could not be loaded. Latest update after summer heat wave:This is a very efficient air conditioner. Buy it for summer use. It blows cool air nearly immediately and runs at twice the efficiency of another brands "quiet" inverter unit. Average daily use in same setting is 2 kwatts versus the other brand's 4 kwatts. This box shaped unit is much quieter than the U shaped unit, which essentially acts like a tuning fork anytime the compressor is running hard. Again, winter use is a no go- it runs the compressor twice as hard (burning 600 watts per hour vs typical 300) and is much louder in heat mode... rumor has it there was a software update to run at lower temps but I would not want to. It's more efficent to remove the unit to keep the wind out.Winter Update:Both of my Midea units are poorly sealed internally. See video showing the strength of pressure change passing directly through the internals of the unit. Video shows the U shaped unit, which is actually the less problematic in terms of internal leaks because of the slim connection to the outside half. Due to this fault, I cannot leave the reviewed heating unit in place through winter to use for heating on mild days. The blast of arctic outside air infiltrating into the house through the internals of the unit defeats any gains from heat pump technology. I will have to remove the shell of the unit to silicone all the leaks. Additionally, this explains why in summer the humidity inside was worse than ever- these units are poorly sealed. I contacted Midea customer service to adivise if there was an internal vent to close. They said all their units are internally sealed and were quick to blame installation. Given that no installation method could cause a constant breeze through the internals of the unit, it is evident that shoddy manufacturing practice is being covered up. As of now I cannot recommend any Midea brand AC. I'm feeling less hurt that this model has been stupidly discontinued instead of improved upon.Original review:Don't fall for the U shape gimmicks. This unit is just as quiet and efficient, plus currently a lower price than the big box store has for the U shaped one. But it has the ability to heat your room using the heat pump for 90 percent of your waking winter temperatures. Heat pumps move heat, rather than generate heat, allowing for much greater efficiency than any resistant coil type electric heaters. Pairs nicely with natural gas furnace running at the extreme low temps. I'll run the window unit in the bedroom at desired temp and leave the furnace on for whole house at my minimum house temp.Pros:1. Much quieter than that other high profile brand that claims to be whisper quiet. There's no water slopping sounds from the compressor fan. It doesn't sound like a jet engine about to take off either. It's a nice consistent wind whoosh.2. Are three 12k window units (36k total) more efficient than the single 18k mini split unit that I failed to get a leakless instal 2 years ago? I'll check the utility records after this season is over.Cons so far:1. it frequently trips the 15 amp GFI on the start of my outlet circuit at start up, with no other draws. GFIs are generally not friendly for high amp draw appliances with built in GFIs on the cord, so I need to run a dedicated outlet for each AC. (The U shaped model does the same thing)Update: I simply removed the GFI outlet and the AC runs fine on the circuit. Again, GFI outlets are notorious for tripping appliances, even under a correct load.2. There's no real temperature control when on dry mode... Blew thru the original setting of 72 and brought the room down to 67. Would love to see and set to a humidity percentage while in dry mode. Haven't tried the app or remote yet. (Might have humidity display options there)3. Product arrived dented. Plenty of Styrofoam in the packaging, but this could be displaced by a couple sheets of 3/4 inch insulating foam on all sides to be cut up for window panels. This type foam would be much stronger protection for packaging too.Update: The dent is not noticeable once installed and has not affected the performance at all.

The 12k btu airconditioner/heatpump combo is everything it advertises to be. Its efficient with the wattage varying from 300watts to 1000 during use depending on the fan and temperature settings. Cooling is fantastic and heating works well. Just to note heating will not start if its below 41F outside but once its going the heating will continue to power through despite it being in the upper 30's. Will be stress testing it heavily since its being used throughout the year. Planning to buy an 8000btu head pump model for my home office.

Amazing Air conditioner. Super quiet. And has a special feature that doesn’t surge your power. It gently will ramp up if it needs to cool the room down or cycle down if it’s reached the temp. We have had many ac units and always use the auto function but this is different. It’s gently does it. Easy to clean the filter. 10/10
