The media could not be loaded. I am very impressed with this 12000BTU mini split system. Installation was straightforward with the included kit, and once running, it cooled my room quickly and evenly. The heating function is just as effective, making it a great all-in-one solution for year-round use. It’s very quiet, even on higher fan speeds, and the 24-hour timer is convenient for scheduling. The 19 SEER2 rating gives me peace of mind that it’s energy-efficient, and it easily handles my 700+ sq. ft. space. Overall, an excellent investment for comfort and savings.

Had a excellent experience with the simplicity of installation. Not implying that this installation for everyone; you will definitely need HVAC skills. The product itself works excellent. Very quiet and cools well. Will update this if anything changes.

Unit works exactly as intended. Keeps our living and dining room at a very comfortable temp. Turbo mode will definitely make it chilly in the house. We live in South Texas and as I'm typing this it's currently 98°F and in the house it is 74. Good, quiet, and classic look. Install was straight forward and easy. You will need to order mounting brackets separately if you want to mount to exterior wall.

Set up was super easy. It took me a little over an hour to install it but I’ve never done one either. It keeps my entire camper cold. It functions perfectly. The remote is simple. The design is sleek. Overall I’m happy with the quality and efficiency of this unit.

The media could not be loaded. Very happy with my purchase. The instructions were a little challenging to follow for me as I haden't ever installed something like this before but luckily many of these minisplits are very similar so a quick YouTube search provided the information needed. You will need to purchase a mount of some kind I hung mine from the wall. You will also need a 410 to 1/4" adapter to connect a standard vacume pump. A drill with a 2 1/8" to 2 1/2" hole saw to go through the wall and possible a power disconnect on the outside next to the unit. Mine is working great. I didn't need the sealant some suggest as there were no leaks from the lines or joints. There is a rippled design on the inside unit that someone else mentioned but it doesn't bother me. I haven't insulated the cieling yet (its in my garage) but it makes a big difference in the Southern Missouri heat and humidity. Great results from one of the least expensive options on Amazon. I got the 12000 btu unit. Haven't used the heat portion yet. Its also really quiet.

We have a small side porch that we enclosed and needed a small air conditioner/heater and this was perfect. We had professionals come and install it and they said it was the easiest one they had installed. It cooks just like we wanted and works great. Why did you pick this product vs others?: Cost was the main reason Temperature control: it is great even at 75 degrees I have to put a little blanket on my feet Functionality: we love the ease of it Energy efficiency: We have not received a bill since we just got it installed a week ago Remote control: love that I can change it from my recliner Design: the design is subtle but modern Air quality: Excellent

This unit is simply amazing, I cannot praise it enough! I waited until we got a power bill to review it, so that I could be thorough. Firstly, installation was a breeze! It took my husband all of three hours to install it. He IS exceptionally handy, though.We have had no trouble with leaks, noise, or anything else that would be considered a defect. The only part that he needed my help with was making sure that it was centered above the window. It is relatively small, so it’s barely noticeable to me anymore. Secondly, it cools my house like nobody’s business. During the HOTTEST month of this year, we were sitting pretty in a 70 degree house. We were comfortable, and there was no humidity on the main floor of my home. We even used 300 kWh LESS than the month before when we had our central unit running as our main A/C. To me, a gardener, a bonus is that the outdoor unit puts out a lot of condensation. It will fill a 40 gallon tub in about a day and a half. No worries there, though! I popped the plastic tub underneath, and I use the water to fill my watering cans for my flowers. We have even used a battery powered pump and a hose to water our vegetable garden, further saving a bit on utility bills! All in all, I would recommend this unit. We are actually considering another, smaller one for the second story of our house.
