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

***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

Ok So I ordered this split on 7/10(Friday) ..it bothered me it was $100 delivery charge for delivery on 7/16(Thursday).it showed up on Saturday (7/11).!!!!..that also bothered me...I was planning on being home to accept the delivery...but it was waiting for me when I got home. This was for the bedroom above our garage and it gets sun all day long.. 2nd..I didn't notice it till days later that the box had some damage..we opened it and there was damage to the metal housing...I thought..ok .no problem,just bend it back and it's mostly cosmetic damage.. We just finished installing it today, I'm lucky that my son it a certified HVAC technician actively working on units daily,we live in Las Vegas. We got everything mounted and secured and connected to panel... Turned on power and went upstairs to start it... turned on with no known issues... great its running and cooling..I thought to myself it alittle louder than I thought...but it works. Went back down stairs to clean up after installing...that's WHEN WE HEARD IT...YHE METAL HOUSING HAD PUSHED UP AGAINST THE FAN BLADES every revolution the blade struck the housing...shut everything down... inspected the housing and fan... pushed out housing some and restarted it...now making no noise. Besides this..the unit done work and cools good ... show more
