21 SEER2 12000 BTU Mini Split AC/Heating System, Wifi Enabled

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.

Received this a few days ago. I live in an old mobile home, and, the walls are super thin, the insulation is virtually non-existent, gaps around all the windows, etc. We currently have three window a/c units in a less than 1000 sq. ft. trailer. The furnace was stolen before we bought it, and was not easy to replace. We figured out a work-around, and it has sufficed, but, the duct work throughout is damaged or collapsed in many places, and is not easy to access. Our power bill has been extremely high due to these circumstances. So, we started looking into the mini-splits. They were much more expensive just a few years ago. We thought we would start with one in our kitchen/living room area to see how well it worked. My husband just finished installing it yesterday, the only holdup being a part we needed to order that was compatible with the mini-split and the vacuum pump that is needed to evacuate the lines once installed. Installation was fairly straightforward, and my husband was able to do it himself. Once he was finished, we turned it in to test the system, and the difference was immediately noticeable. The unit is so quiet, and it cooled those two large rooms very quickly when the outside temperature was about 85 degrees, and I had all the curtains open, plus grandkids running in and out the door. We are definitely going to purchase another unit for the back of the trailer, and are really looking forward to seeing the savings on our energy bill. So far, extremely happy with this unit.

I have bought one of these units before they worked really well, but it seems to be a major problem with delivery right now two orders bought neither one of them delivered when you get one and install it. It works good really cold and the installation is fairly easy once you managed to get the unit delivered correct correctly.

Great Value! Unit functions perfectly. Easy install. Note: I have installed / worked on several AC systems in the past so already had the required equipment / tools to make this an easy process. If you need to cut the line set for placement, you MUST have the proper flaring tools or be prepared to braze the lines prior to vacuum testing. Cools my garage workshop quickly and efficiently! Extremely quiet too!

This is our first large AC unit so we did not have repair tools. The large tubbe is 16mm which is NOT compatible with 5/8" flairing tools. The tube was cheap and brittle so of course it collapsed when bending it. We did the repair with a flaring kit bought here which contained both metric and standard (16mm and 5/8"). Once installed, the wire round connectors had to be sliced open because the connection screws are not removable. The it is finally all done, vacuum down for 1 hour and held solid at 29 lbs (?) of vacuum for one hour. Plugged in and kept powered up but NOT running to allow the little heater to fully warm it so the ac will last as long as possible. Once running, blows well but the inner swing does not move. It is available on the remote but apparently some are manual and some are electrically controlled. I am unclear how ours is as the remote implies it is not working correctly. It has been 18 hours and we are still in a cool home. So 4 stars but I considered 3. FYI. Good luck and hopefully you, too will enjoy the end product.

You can't really speak to a company's customer support until something goes wrong. I purchased and installed this unit it myself, which was a straight forward process for a reasonably handy DIY'er. The unit performed flawlessly for a good deal of time, but it seemed like something failed with the condenser fan and the outside unit over heated. It was past the return window so my heart dropped. I reached out to the support email address and recieved a response in less than 24 hours asking for a few pictures and some info. Long story short the team at Yithome offered to send a new outdoor unit or to send a small refund to help pay the cost of having someone come out and fix it!!! I opted for the replacement condenser and the team responded with a tracking number in a short time. The unit arrived very quickly and I'm back up and running! FIVE STARS for an outstanding and well built product, and for stellar support. Buy from Yithome with confidence!!!

Okay so I think most of us start off as skeptical of how affordable these are as to the quality, but I have to say this is the best purchase I’ve made in years! It came a day early and I put it in the same evening. Took around 4 hours to install but I’m no expert so it may take others less. I made an adapter plate out of plywood to put the head unit further down on my window, and I also put a 20amp 110 plug on the end. Works great with a 20amp dedicated breaker. You’ll need the vacuum out the lines with the pumps you see on here, I used the one that was $130 and it worked great. After you tighten the lines and hook up the hoses, make sure to keep the Allen screws in, vaccine the lines for 15 mins, and then turn the low side pressure knob off. If it rises back up there’s a leak, if not after 5 mins you’re all good! And you can open up the Allen screws. Again novice here but this was super easy and I’m very impressed with how well it cools, waiting on the heat as of now, just cause it’s summer.

**1.5 Year Update – YITAHOME 12,000 BTU Mini Split AC/Heating System** I originally gave this YITAHOME 12,000 BTU mini split a good review after purchasing it on 3/18/25. At first, it was a great little unit. It cooled and heated efficiently, was quiet, and kept the space comfortable without constantly running. Installation was straightforward for someone with basic DIY skills, although you do need a vacuum pump and manifold gauges to properly install it. Unfortunately, after about a year and a half, my experience has changed. During the winter, the heating performance started to decline. Over time, it lost more and more ability to heat, and now the cooling performance has also dropped significantly. The unit that once worked great is now barely able to cool the room. I looked into having it repaired, but the cost didn’t make sense. Even just having the refrigerant checked and topped off was expensive enough that replacing the entire system was the better option. The refrigerant used in my unit is no longer commonly available and has become very expensive, making repairs impractical. While the initial performance and installation were impressive, the long-term reliability has been disappointing. A mini split that only lasts around 18 months before requiring a costly repair is not what I expected. I’m lowering my rating from my original review. It was a great-performing unit when new, but the short lifespan and expensive refrigerant situation make it hard to recommend for long-term use.

Easy, install quiet very effectively cold effectively.Warm sleek and fits nice to the wall.Good brackets

Super
