I’m extremely happy with this mini split AC! It was packaged really well and arrived in perfect condition. The installation was straightforward, and it started cooling the room almost immediately. It runs very quietly, which is a huge plus, especially at night. The temperature stays consistent, and the airflow is strong without being too noisy. The remote is easy to use, and I like that it has cooling, heating, drying, and fan modes all in one unit. It looks sleek on the wall and blends in nicely with the room. The overall quality feels much better than I expected for the price. After using it for a while, I can honestly say it performs great and keeps the room comfortable in any weather. I would definitely recommend this mini split to anyone looking for an affordable, reliable, and efficient air conditioner. Great value for the money! ... show more

    • 💰Save Money True 110V/115V convenience 💰

***I give it 5 out of 5 stars ⭐️ *** We live in the desert of Nevada near the Utah border. We purchased the mini split on June 12 and ever since the unit has been on 24/7. Finding a unit with the right budget was a very big challenge and durability. What caught my eye for the Rallytech mini split was that it was pre-charged system and it was heating and cooling along with 750 ft.² of coverage, that pretty much sold me there and of course the price. What I like about the unit: True 110V/115V convenience means no upgrading to heavy 230V breakers. Massive coverage area handles up to 750 square feet easily.19 SEER efficiency and Eco Mode keep electricity bills surprisingly low. Whisper-quiet 42dB operation alongside a display-off sleep mode avoids sleep disruptions. Powerful 4-in-1 system with strong cooling, 12,500 BTU heating, fan, and dehumidifier modes. So far it’s been delivering powerful and consistent comfort across and part of our house that is 1600 ft.². This is without the loud, intrusive noise of a standard window unit, it’s truly comfortable. Folks, this is definitely a DIY project. Just follow the videos they show you and work along with Gemini and the combination makes it less stressful. On top of that they have a very comprehensive after sales support and technical guidance, backed by an eight year warranty in 24 hour customer service. I added the Allstate insurance on top of it. With the inflationary situation with all products it’s great to find something within reach that fits your budget and Rallytech truly delivers that budget comfort. Based on what I’m seeing and experiencing with the mini split, I believe that I bought a durable product that will last me and save me from paying higher energy bills. ... show more

I’ve owned a lot of window units over the years, and I honestly didn’t think a mini split would make this much of a difference. I was wrong. I live in Florida, where the heat and humidity are relentless. With my old window unit, I had to keep the thermostat set at 69°F just to stay reasonably comfortable, and it still struggled. With this system, I keep it set at 78°F and I’m actually cold. That’s how efficient it is. The biggest difference isn’t just the cooling—it’s the humidity control. This unit pulls so much moisture out of the air that my home feels dramatically cooler and more comfortable. The air feels crisp instead of damp and sticky, and that’s something no window unit I’ve ever owned could accomplish. The system arrived quickly, was well packaged, and the installation was straightforward. Once it was up and running, it exceeded every expectation I had. It’s whisper quiet, cools my entire home evenly, and barely seems to work to maintain the temperature. If you’re on the fence because you’ve always used window units, stop thinking about it. There is absolutely no comparison. This is one of the best purchases I’ve made for my home. It has completely changed the comfort level in my house, and I only wish I had made the switch years ago. Five stars isn’t enough. I’d give it ten if I could. ... show more

It’s better than our Ameristar mini split which immediately had problems. This unit sends cold air it’s very nice! The heat also puts out good but I will update review when it’s used in the wintertime. I had a professional electrician install it since we don’t do DIY on electricity projects. The price is great! I hope this will last a long time. I’m fixing to buy more for the other 2 rooms as our house do not have a central unit. ... show more

⭐⭐⭐⭐⭐ Excellent Ductless Mini Split! I’ve been very impressed with this ductless mini split. Installation was straightforward, and the unit doesn’t take up much space, which makes it perfect for my trailer. It’s also extremely quiet—you hardly notice it running. The cooling performance has been excellent. Even on days when the outside temperature reaches 105°F, it keeps the inside of my trailer comfortably in the 70s. That’s impressive considering how quickly a trailer can heat up in the summer. Overall, it’s easy to install, compact, quiet, and does exactly what it’s supposed to do. I would definitely recommend it to anyone looking for an efficient way to cool a trailer, RV, shop, or other smaller space. Five stars! ... show more

Read the instructions thoroughly and also watched a couple of videos before I started the install. Once everything was hooked up, I had my AC contractor look it over and now it's working perfectly and cools the space down so quickly and quietly. Great investment!
