8,000 BTU Smart Inverter Air Conditioner Window Unit with Heat and Dehumidifier – Cools up to 350 Sq. Ft., Energy Star Rated, Quiet Operation, Electronic Controls, Remote Control, White

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. Pros Cold when you want it Warm 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 easy Included remote works well They include locking screws and insulating tape for installation. The top groove and side blocking pieces are included, but you have to attach them Cons If you have sensitive hearing, you'll hear the high pitched whine from the inverter system My LED lights on the same circuit as the AC flicker in a slightly annoying way In 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 target Unit was a bit wider than the old AC, and I had to get creative with the side blocking pieces and insulating tape At 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

Let me start with the notes/limitations: * This thing weighs *a lot*. That weight combined with its center of gravity sticking out of your window quite a bit further than standard window units puts quite some stress on your window frame. In other words, If your windows are not sturdy then this unit is probably not a good choice. Silly as I am I went a step further and framed a 14x19 hole in the wall underneath the window. So now it functions as sort of a PTAC (Those things you see under the window in a hotel.) * It heats with outside temperatures as low as 41F but not lower. For those days that the temperatures go below that you need to get yourself a $15 wallyworld space heater. How often you are going to run that space heater depends on how far south you live. Don't wait until you need that space heater because they will be sold out. Get it now. Then the things I like * It's not your typical window rattler. This thing is unnoticeable quiet. It starts quietly and it runs quietly. * It's a inverter type A/C with heat pump capabilities. Look for any A/C system with those capabilities and you will be out at least $600. This thing is a bargain. * The unit is easy on your breakers. It does not come on with a bang and a lot of the time it will pull less than 200 watt. You can run like 9 of these units on a 15 amp breaker. * Only 3 of these 8000 btu units cool as much as a typical 2 ton central A/C unit. * This thing is a DIYer's dream. It sips power and when installed as a PTAC it cools and heats a home beautifully. No EPA 309 certificate needed.

The product's air-conditioner function is quiet initially, but develops a loud sound during operation after a few weeks. The sound can initially be addressed by wedging cardboard between the inner motor and outer frame. This workaround works for a week or so, then the loud sound returns. The real issue is that the unit's heat function does not work. The unit does not operate when the outside temperature is 41°F or below. The unit is designed that way, but not advertised that way. We purchased the product in July. The weather where we live does not get below 50°F until November. Initially Midea customer service stated that they would send a refund for both units. The next day they wrote "After reviewing your case, I wanted to provide an update regarding the refund, the refund we submitted was cancelled. Our internal team confirmed that these units are not designed to operate below 41°F. While buyer’s remorse is not covered under the warranty, we appreciate you reaching out and giving us the opportunity to review your situation." I will never buy another product from them.
