This 12000 BTU mini split cools and heats my room perfectly, handling both hot summers and cold winters with ease. It runs incredibly quietly, so I can sleep and work without any noise disturbance at all. I love that it uses standard 115V power and is energy efficient, helping me save a lot on electricity bills. The self-cleaning and auto defrost functions work flawlessly, making maintenance really simple. With reliable quality, smart controls, and eco-friendly refrigerant, this AC is absolutely worth buying.

I installed this in our restaurant, and it has far exceeded expectations. The biggest standout feature is how quiet it is — you can barely hear it running. Conversations flow naturally, and guests don't even realize the AC is on. Heating and cooling are both fast. Even though it runs on 110V, the inverter technology delivers excellent performance. Our dining area is about 400 square feet, and it reaches a comfortable temperature in just minutes. On hot days, the space stays evenly cool without any harsh direct airflow. We also tried the heat pump mode in winter — it warmed up just as effectively. Having both functions in one unit is a great value. The wall-mounted design saves floor space, unlike traditional split systems. With a 19 SEER2 rating, it's energy-efficient enough to run for long hours without worrying about electricity bills. One small note: professional installation is required for the refrigerant lines and wiring, so plan your wall placement in advance. But once it's up, this quiet little unit is absolutely worth it — it has truly elevated the dining experience in our restaurant.

Great mini split AC unit. It cools and heats efficiently and works well for medium-sized rooms. The system runs quietly and feels energy-efficient. Installation takes some effort, but overall performance is reliable. Good value for the price.

Set name: 18000 BTU,208V/230V,19 SEER2
Nice looking unit, but after having it installed by a professional as the instructions state, this unit doesn't won't cool and the heat doesn't blow at all. I can hear the heat pump working the unit just won't blow the hot air. Also the compressor kicks on when on cool but the air doesn't cool down. I believe this unit doesn't come pre-charged like it says and you have to purchase refrigerant for it. Currently trying to get ahold of customer service for a return or possibly a new unit if the one they sent is faulty, but not having much luck. Update: Customer service reached out and was awesome they provided a refund no problem

Absolutely love this mini split! It cools and heats the room quickly and runs super quiet. The temperature stays consistent, and my energy bill has noticeably improved. Installation was straightforward, and the remote is easy to use. Highly recommend for anyone looking for efficient, powerful climate control without the noise of a traditional unit.

We got this mini split hvac system to add to our rental house. Needing a small unit for the dinning room/living room area was the reason for this particular unit. The area to cool and heat is appropriately 700 square feet which this one is said to do 750. With a little bit of research and having done automotive a/c systems for years i decided to install it. For an experienced automotive technician this was a fairly simple installation however I would not reccomend a novice to attempt this. It took most of a day to install it with the cover kit and condenser brackets. Those are sold separately! That said the unit was completed today after I recieved the 410 to 1/4 service adaptor so I could vacuum the lines and evaporator down using my automotive vacuum pump. Then I was able to open the precharged condenser valves releasing the freon into the rest of the system. This little unit works great! It is currently about 45 degrees out and the heat function is nice and warm. We checked the cooling and it was very cold. So far this is a very good unit for the price. We're happy and the tennant's are to.

Product did not work well & did not maintain temperature inside at all. When it was hot it stayed hot and when it was cold it stayed cold. Had it looked at by a professional and they said it is the unit not the installation.

The unit arrived on time in protective packaging with no damage. The indoor and outdoor units were packaged and delivered separately, so there’s no need to worry. The outdoor compressor feels well built. The indoor unit looks neat; I like that its profile is slightly wider than some other models and its cleaner, simpler front panel gives it a more elegant, premium appearance. It cools and heats my bedroom effectively and runs so quietly — Anyone who has suffered the noise of typical HVAC systems installed by builders will understand what a relief this is 😄.
