YITAHOME 18000 BTU Mini Split Air Conditioner Heat Pump System, WiFi Enabled 21 SEER2 208-230V Inverter Ductless AC Compatible with Alexa, Cool Up to 1250 Sq. Ft, Complete Installation Kit, 1.5 Ton

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.

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.

My wife and I bought our first home together a year ago as of writing this. We needed to replace noisy, inefficient baseboard heaters in our downstairs living space. After some thought and research, we decided to order this unit. Having a background in automotive, carpentry, woodworking, and electrical, I felt more than confident to take on the task of installing the unit myself. Installation was... difficult. It takes a lot of precise planning on hooking one of these up, including the electrical, running the plumbing/drain hoses. The unit did what we needed it to most of the summer. It was warm in early summer, and blew nice cold air on hot summer days. For the most part, we didn't have any serious problems with it. Fast forward to now... This YITAHOME mini split, in the last 2~ months, has become a stressful nightmare to me. The colder it got, the louder and louder it got and ran. It was barely blowing warm air. The noise was INSANELY loud and debilitating, it sounded like a power plant some evenings. But it was our only source of heat for a significant part of our house. It caused me many sleepless nights, worrying about it failing (or worse), and the stress of it failing and making our house get too cold. I have tools to detect leaks and there were no significant leaks in the system. Someway, somehow, the heat pump/compressor system started to catastrophically fail. I called around for help, and no one will touch this unit, because it is not a well-known, brand name mini split you can order parts for. Eventually it totally crapped out, and we are now paying professionals $8,000+ to put a high-end Carrier system in. I am out a LOT of money, including the tools and fittings I had to buy to make this work. I can't put into words the amount of stress this YITAHOME mini split has caused me. The installation, the noise, wrecking our sleep, all of it. I think, people need to be VERY cautious about buying this, or any of these "DIY" brand mini split systems. YouTube videos make you think these things are very doable, but they don't paint the full picture. This thing was very trying for me, and I have a lot of experience in the skills needed to install one of these. And it's failure is $700 + another $500 down the drain in tools and accessories to do the job and diagnose issues, not to mention all the stress it's caused me. The pros told me these Amazon units (including this brand and "Mr. Cool") only come with a 1-year warranty because they're junk, and you can expect the parts to fail, and you can't replace them after. There's a reason pros charge so much money to do these. They're very delicate machines that require a very good vacuum and then a very precise amount of refrigerant. Despite these units coming "precharged", I question if the refrigerant amount was off. If you are going to go the DIY route, number one; I don't recommend this brand. And number two; I really wouldn't use this on a critical space where you live in and need heat, especially in frigid winters where it can fail. If I were gonna do a DIY unit again, I would only do it in my barn/workshop.
