Midea 5,000 BTU EasyCool Small Window Air Conditioner - Cool up to 150 Sq. Ft. with Easy-to-Use Mechanical Controls and Reusable Filter, Perfect for Small Bedroom, Living Room, Home Office

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

Five stars! It works! It cools and heats. Very quiet. Several times I thought it was off because of how quiet it was. Efficient. No damage. On time.The AC seems like it’s 5000 BTU but it does eventually cool like an 8000 BTU. The controls are an issue sometimes. I’ll turn it on, default ac auto and set the temp for 2 degrees below room temperature and it will blow air that’s not very cool and then cycle off. I always have to set the temperature farther down to get it to start cooling. The heat is also not easy to turn on. Again the thermostat on the remote has to be set much higher. The unit fan does not come on and it’s still a confusing process to get heat but it does work good. One time it was stuck flashing “AP”, a WiFi connection mode? I am not using the WiFi or phone app yet.The AP went away by itself in a few minutes.Installed it myself, from inside the window with no issues but it’s heavy. My electric usage is showing that this unit is very efficient with ac and heat. Also, the heat works great but you’ll need another heat source for very cold weather.

These things have come a long way since I last needed one. This thing is surprisingly quiet and much more energy efficient than the ones made just a decade ago. If you can't have central air or a true mini-split, then this is about as close as you can get to one in a window unit, at least when it comes to noise and efficiency. I think it would be particularly good in a bedroom, home office or anywhere where you need A/C but really want the quiet of central air. The unique thing with this unit is that it comes with a reversing valve just like those bigger A/C systems, meaning it can run in reverse and heat the room as well as cooling it. Well, sort of. It has an 8,000 BTU cooling performance but only 7,000 BTU of heat output. So for some reason, it is a bit less efficient when used for heat. However, that heating inefficiency is relative, since it only pulls about 600 watts in heat mode, meaning it is well over 3x as efficient as a traditional electric space heater that pulls 1,500 watts and provides only a bit over 5,000 BTUs of heat. So for those cooler spring/fall nights it may still very well be the cheapest source of heat in your house. That is the magic of heat pumps, it always takes less energy to just move existing heat that is already in the air somewhere else than to create it. However, unlike a bigger mini-split or central AC unit, it cannot defrost the outside coils in cold weather, so it can only provide heat when the ambient temperature outside is 41 degrees or warmer. It also has the problem every window A/C has - you can't really get a perfect, energy efficient seal around it and even if you could seal around it well, the metal unit itself is still going to let a fair bit of cold into the room if you leave it in place all winter. So you really still have to do what you do with every other window unit in a cold climate and pull it out of the window entirely during the coldest months of winter. I found that taking it in and out of the window to be just about as heavy and cumbersome as it always has been, so this new design isn't any lighter than the window units from 10-20 years ago. Having a true, four season heat pump in a small, compact window unit would be a total game changer. This is definitely not that product, which is a little frustrating because it is so close but just falls a bit short. I am not sure why they couldn't design this as a cold weather capable heat pump, but they didn't, and so don't buy this expecting it to provide virtually 100% of your heating and cooling needs unless you live somewhere that almost never drops down to 40 degrees at night.

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.
