Set name: 12000 BTU 115V / 20 SEER2 / WIFI
This unit works really well even on some really hot days in the 100's. The ECO mode works great for maintaining the temperature after the room has been cooled, so far it hasn't been particularly expensive to run, I use it in my bedroom at night so I can't speak for the effectiveness in a large room, but for a bedroom this the cheapest and most efficient way to keep the room comfortable in the summer. I haven't tried out the heater yet, but that'll be in an update in the future. The unit is very quiet, you can barely tell it's on, the mute setting is probably not the most efficient setting but it does keep the room around 3 degrees of the set temperature late at night and it doesn't make the room drafty. The only qualm with this unit is the blower doesn't shut off after the set temperature is reached and it sometimes gets a lot colder than the set temperature, I had it set to 65 and it got down to 51 one night, I don't know why that happened, but on the ECO mode it seems to stay within the set temperature range until I turn it off. The app works great and is very easy to use, there's a setting to purify the air and it seems to work, although there's some debate on the potential dangers of being in an enclosed room while it's set, due to some ozone being produced. There's also some timer settings and a sleep mode that allows for the temperature to be gradually changed throughout the night until it turns off. The unit was very easy to install, the hardest part is making a hole in the wall and bending the lines, everything is very basic. You will need some extra things to install it. I bought a whip to run power to the main unit directly from the breaker box and a pull out disconnect. I used a vacuum pump to vacuum out the lines and check for leaks, I used Nylog on the fittings, I highly recommend it, I had no leaks whatsoever, overall it's very easy to install and can be done in 2-3 hours depending on what your walls are made of and the distance you have to run the lines.

First off, I want to thank Amazon for stepping up and making things right. That kind of customer service goes a long way. As for the product itself — very simple to install, the instructions were clear and easy to follow, and everything was straightforward to work with. Once installed, it performs great and delivers nice, cold air just like it should. Overall, I’m happy with both the product and the support behind it.

I’ve been using the YITAHOME 12000 BTU mini split for a few months now, and I’m really impressed with how well it performs. The cooling power is excellent. Purchased for our ADU we built. It easily 500 sqft area cool even during hot afternoons, and the heating function works surprisingly well on chilly nights. Installation took some time but was very straightforward thanks to the complete kit and clear instructions. I appreciated that everything needed was included, which saved me an extra trip to the hardware store. Once it was up and running, the unit was whisper-quiet and very energy-efficient. The WiFi control and Alexa compatibility are great modern touches. Being able to adjust the temperature remotely or with voice commands makes daily use super convenient. Overall, this YITAHOME mini split offers strong performance, sleek design, and features that usually cost much more in other brands. Highly recommended for anyone looking for a reliable ductless system without breaking bank.

Set name: 12000 BTU 115V / 20 SEER2 / WIFI
After seeing some of the reviews I decided to try this ac. I needed to replace a 12000btu Soleus Air unit I bought 11 years ago that finally died. It worked really well and I was hoping this unit would do the same. Well...the first one lasted 2 days before it was blowing warm air only. And it never really blew cold air either. It was more like cool-ish air. I reached out to Amazon for a replacement which came with its own set of issues but they sent a replacement. It's lasted more than two days (on day three...) and, like the first one, never blew actual cold air. It's cool-ish. Now on day three it's even less cool. After running literally all day it can't even cool my 400 square foot office. My old Soleus Air unit could make the room downright cold. And it was the exact same 12000btu. I will be reaching out to the company for support and will update this review if anything changes. But my advice is do not buy this unit.

Purchased on 3/18/25, and this YITAHOME 12,000 BTU mini split has been working great so far. It cools and heats efficiently and keeps the space comfortable without running constantly. Once installed, it’s quiet and performs exactly as advertised. The physical installation was surprisingly easy for a mini split. If you’re even moderately handy, it’s very doable. Just be aware that you will need a vacuum pump and a manifold gauge set to properly evacuate the lines — those are not optional and not clearly emphasized. My only real complaint is the app setup. The Wi-Fi instructions are practically non-existent, and getting it connected took way longer than it should have. Once connected it works fine, but the setup process is frustrating. Overall, it’s a great unit for the price with strong performance and straightforward installation. With better Wi-Fi instructions, this would easily be a 5-star product.
