Advantage 5G 12,000 BTU 21.5 SEER2 Ductless Mini Split Air Conditioner and Heat Pump - 230V

The MRCOOL® 5th Generation 12K BTU 230V Advantage Mini-Split System offers efficient, eco-friendly comfort designed for spaces up to 500 sq. ft. This ductless mini-split system includes both the sleek indoor air handler and the high-performance outdoor condenser, working together to deliver consistent heating and cooling year-round—with powerful smart features and environmental responsibility built in.

Both the air handler and condenser utilize next-generation R-454B refrigerant, offering improved energy efficiency and significantly reduced environmental impact compared to previous models. With a Global Warming Potential (GWP) that is about 80% lower than R-410A, this system helps you reduce your carbon footprint while keeping utility costs in check.

The air handler operates quietly and blends seamlessly into any room. Built-in Wi-Fi connectivity allows for remote temperature control using the MRCOOL® SmartHVAC app or voice commands via Amazon Alexa or Google Assistant. You can even schedule temperature adjustments overnight for better comfort and energy savings while you sleep

The condenser, when installed by an HVAC professional, delivers outstanding efficiency with up to a 21.3 SEER2 rating and 9.1 HSPF2-4, helping to lower energy bills while maintaining reliable climate control. And because it's a ductless system, installation is faster and more affordable than traditional HVAC setups.

Enjoy peace of mind with MRCOOL’s 2-year parts warranty, 1-year compressor warranty, and 1-year remote control warranty upon registration. You can also enroll in the MRCOOL® Care Program to unlock a Limited Lifetime Warranty for extended protection. Whether you’re upgrading a bedroom, office, or small living area, the MRCOOL® 12K BTU 230V Advantage System brings smart, cost-effective comfort without compromise.
