The highly efficient 5th Generation 9k BTU 230V Advantage System is a powerful, eco-friendly mini-split unit that allows you to directly control the temperature of the space it's installed in. This system must be installed by an HVAC professional, but since it is a ductless system, the process is much less time consuming and expensive than a central system With the capacity to achieve up to a 21.2 SEER2 rating and an HSPF2-4 of 9.1, this system will decrease energy usage while increasing how much money you save. This generation uses R-454B refrigerant instead of R-410A, making it a much more sustainable and environmentally friendly choice, as R-454B has a GWP (global warming potential) that is nearly 80% lower than the previous refrigerant. Because of this, you can save the world just by sitting and enjoying perfect comfort in your living room With coverage up to 400 sq. ft., the Advantage is perfect for those in need of a quiet, convenient, and proficient system that gives you all the features you need. One of those features is the Wi-Fi control module, which simplifies system setup and gives you access to operate your system through your phone and Amazon Alexa or Google Assistant. Register your unit online and enjoy peace of mind with MRCOOL's robust warranty: 1 year on parts, 2 years on the compressor, and 1 year on the remote control.
