  • Efficient, Quiet, and Perfect for Year-Round Comfort Efficient, Quiet, and Perfect for Year-Round Comfort
Style: 12000BTU,115V,19 SEER2
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. ... show more

This is my first time buy 12000BTU split-type air conditioner inverter heating and cooling and installed it myself. Affordable compared to central air conditioner typically use in home, split- type air conditioner are much cheaper to purchase. Installation is relatively simple and quick, requiring no major structural changes to the building. When you turn it on, it’s quiet and doesn’t make a lot of noise. It also cools and heats so quickly. My family all like it. ... show more

Awesome unit for heating and cooling. Temperatures are great in both settings. Installs in one day. Customer service was great as we had a few questions about operation. My unit was installed in 10x20 insulated out -building used for photography. I replaced an infrared heater and portable ac unit and I am very happy with this mini split unit. It looks so professional and takes up little to no space. Highly recommend. Price was also perfect for us "starving artists"! ... show more
