MideaMAP12S1TBL Air Conditioner, 12,000 BTU-dual hose, Black

I have now purchased two Midea Duo 14,000BTU units. They both had mechanical issues on first use which I had to investigate and resolve. After that they have both been phenomenal. I would not buy any other unit, because I have bought other brands and theirs cannot hold a candle to Midea. See below for Midea issues as well as praise. Note: these Midea units have a large rotary fan which is held by a massive rubber… grommet? rubber… bearing? at only one end of the rotary fan. The fans also have a unique structure cast inside of the rotary fan (presumably to help draw air from one chamber to another within the ac unit). This unique fan structure and unique mounting of the fan requires Midea to counterweight the fans with metal weights at the factory. This style of fan has also lead to vibration and potential self destruction in these units. But when it works it works well.Praise: The unit itself is phenomenally well made, incredibly well thought out. Every detail has been planned for and the instructions are clear. The build quality is very good, form factor is excellent too. The Midea app is great and integration with the new device was seamless. The install video is great too.The ac works wonderfully well. Heat mode works phenomenally well and is super quiet. Heat mode does not require reconfiguration or any particular preparation other than hooking up the drain line. I used the included drain adaptor to run a 1/4” black silicon line to a glass gallon jug for heat condensate drainage. The Midea Duo 14,000 BTU unit (with heat) has an internal pump that pumps out condensate from heat mode. This is very helpful.Issues; Within a minute of turning on my first unit, it made a HORRIBLE persistent rattling sound. The compressor/cooling lines were rattling against each other. I was able to get in where these lines were and slide the vibration-dampening sleeve that was already on one pipe, further down the pipe, so it would actually keep the pipes from rattling against one another.My second unit (after sitting for 16-24 hours as it should) made a high pitched metal-on-metal squeaking sound emanating from the compressor when I turned on the ac. I immediately turned the unit off, pondered for a bit, then ran the unit in heat mode, this immediately resolved the metal-on-metal squeaking issue. It now runs perfectly in heat or cooling mode.P.S. These units do make a high pitched whine sometimes, but most people will learn to tune it out.Do not attempt to repair these without some knowledge and caution of these sorts of things.P.P.S. This unit replaced a Whynter ARC-14S that was much bigger, louder, had no heat, and finally, it did not work well. So Whynter went back!Edit Jan 2023:This unit is 8 months old and now periodically emits a loud buzz and does not work. I believe the compressor is freezing up. The issue occurs a few times a day, sometimes once a week. Midea Customer Service asks silly questions and marked my ticket as "Solved" when I failed to reply within 5 days (including weekends). Not impressed. I am now seeking a replacement or refund if possible.Edit Jan (late) 2023: Midea customer service refunded me for the malfunctioning unit. I am a little concerned that it was not worth repairing a $700 unit, and now I must pay a $60 disposal fee for freon containing devices in CA, but overall I appreciate Midea’s customer service.

I bought one of these for my house (which doesn’t have central air or normal windows that a conventional AC could fit in). At the time, I was at the end of my rope. I had tried all sorts of portable air conditioners. Single hose ones, dual hose ones. “8000” BTU models. 12,000 BTU models. Every one of them had problems. Most couldn’t cool down a single bedroom.Then I bought this shiny new Midea, with its composite hose design. Surely this was the right choice!I set it up, and started running it in my room. At last! It started cooling, and cooling well. My room became ice cold for the first time in ages. I was perfectly content for a while, and there were no issues. I would clean the filter regularly, and drain the unit on humid days without incident. I was so happy with this AC, in fact, that I got another, for the downstairs living room. That one worked great for a while too.Then, miraculously, just this summer, the problems began. Both units, within a WEEK of one another, stopped working right. Our rooms weren’t cooling down nearly as well as they used to. I started hearing crackling noises from within each unit when I spun them up, and they would halt with an error code after a while of running them. I checked to see if it was an issue of humidity - nope. Then I checked the filter, and… what the…?! There was a thick layer of ice built up all over the back of the unit, blocking the filter fins entirely. I was freaking out. I checked the other model. Ice on that one too. And then the ice would melt and drain directly into the inside of the unit, and they would stop entirely at that point, due to being waterlogged.I got ahold of Midea Support for some help, but they wouldn’t do anything for me, since “the warranty was up”. The best they could do was refer me to some sketchy HVAC repair location nearby with 1 star on Google Maps and a load of reviews saying the place was a scam. So incredibly unhelpful.Now I’m stuck with two oversized paperweights that I have to drain into my bathtub for a minimum of 4 hours each so we don’t get any mold growth, and no way to get my money back for TWO faulty products that both stopped working suspiciously around the same time. I’m guessing Midea’s “warranty” period is so tiny because these things are made to fail over two summers of use. It makes sense - keeps you buying more and more of the same overpriced piece of junk that will continue to break over and over for as long as you have money in your savings account.At this point, I’m completely out of options, and I’m sitting in a pool of my own sweat. Thanks, Midea.
