Features

  • Quick Cooling & Heating: With impressive 18000 BTU cooling and heating capacity, this mini split air conditioner offers consistent comfort for all seasons, ideal for areas up to 1000 sq. ft. The outdoor unit features a chassis electrical heating system that prevents freezing for stable performance in extreme weather, even when temperatures reach as high as 126F or as low as 5F.
  • Convenient Smart Control: This WiFi-enabled split AC system allows you to adjust settings via smartphone or voice control with Alexa or Google Assistant. The included remote control with LED digital display also makes on-the-spot adjustments simple and intuitive.
  • Superior Energy Efficiency: The advanced inverter technology keeps the compressor operating stably and provides energy savings of over 30%. In addition, this 18.1 SEER2 air conditioner uses R32 refrigerant, which has a lower environmental impact than R410A refrigerant. GWP of air conditioning refrigerants is 675.
  • Multifunctional & User-friendly Features: Designed for versatility, this inverter split air conditioner features 7 modes (auto, cool, heat, dry, fan, sleep, ECO) and 6 fan speeds ( auto, quiet, low, medium, high, turbo). Other functions like 4D auto swing, child lock, 24H timer, C/Fdisplay and more add extra convenience and comfort.
  • Quiet Operation & Easy Care: With a noise level as low as 23 dB and display off function, this mini split air conditioner and heater system ensures you enjoy undisturbed rest. The self-cleaning at a high temperature of 133F maintains air quality, while the removable and washable filters make upkeep hassle-free. Note: the professional installation is required.

I couldn't be happier with this mini split system! We had it professionally installed, and it has made a huge difference in keeping our space comfortable year-round. The 12,000 BTU capacity is more than enough for our room, cooling it down quickly on hot days and warming it up just as fast when temperatures drop. One of my favorite features is the WiFi connectivity. Being able to adjust the temperature from my phone or with Alexa is incredibly convenient, especially when I want the room comfortable before I get home. The included remote is also easy to use and has a bright display that's simple to read. The unit runs surprisingly quietly—even at night, it's barely noticeable. Sleep mode and the display-off function make it perfect for bedrooms, and the self-cleaning feature along with the washable filters makes maintenance much easier. I also appreciate the energy-efficient inverter technology. It keeps the temperature consistent without constantly cycling on and off, and I'm looking forward to seeing the savings on my electric bill. With multiple operating modes, adjustable fan speeds, 4D swing, and thoughtful extras like the child lock and timer, this system is packed with useful features. Overall, this is a high-quality mini split that's powerful, quiet, energy-efficient, and loaded with smart features. As long as you plan for professional installation, I highly recommend it. ... show more

Works pretty well. Hopefully it lasts. I can’t find replacement parts for it when looking online. Would be nice to get a spare remote.

We were worried that a mini split might be noisy, but this one is surprisingly quiet. Our bedroom isn’t very large, so the 12,000 BTU capacity is more than enough. It cools the room fast and keeps the temperature comfortable without constantly cycling on and off. The indoor unit also looks much nicer than I expected. After installation, it blends in well with the room. So far, it’s been energy efficient and easy to use. Very happy with this purchase! ... show more

★★★★★ Summer arrived a little late this year, so I bought this unit ahead of time and didn't really get a chance to use it much at first. Now that the weather is finally heating up, I'm so glad I installed it. The unit is surprisingly quiet, but don't let that fool you—it cools incredibly well. Within minutes, the whole room feels comfortable, and the temperature stays consistent. I was worried a mini split might not be enough for my space, but it has exceeded my expectations. Easy to control, energy efficient, and very comfortable. So far, I couldn't be happier with this purchase. ... show more

    • Saved us this summer glad we already had the electrical line
Set name: 12000 BTU, 208-230V, 18.1 SEER2-WIFI
Review Image by Lucy
My husband and his buddy tackled the install themselves and it took them a solid 3 hours start to finish. Honestly relieved it's done because this NYC heat this summer was becoming unbearable before we got it running. One thing that could've been a real problem this needs a dedicated 220 line running to the outside unit and we got lucky the previous tenant had already set one up for their EV charger. My husband just tapped into that instead of paying an electrician to run a whole new line which saved us a decent chunk of money honestly. Living room is genuinely cold now like actually cold and not just 'less hot' like our old window unit used to manage. Display on the indoor unit looks sleek too and fits the room better than I expected and it doesn't look like some bulky appliance stuck on the wall. The mobile app works fine for adjusting it from bed before we even get up. For anyone else in an older house without existing 220 wiring just to you know that part's not optional but if you've got a line already like we did and definitely makes this whole project way easier. ... show more
