Advantage 5G 18,000 BTU 21.5 SEER2 Ductless Mini Split Air Conditioner and Heat Pump - 230V

Enjoy high-capacity, eco-friendly comfort with the MRCOOL® 5th Generation 18K BTU 230V Advantage Mini-Split System. This powerful ductless system includes both the indoor air handler and outdoor condenser, working in tandem to efficiently heat and cool spaces up to 800 sq. ft. with whisper-quiet operation and smart controls that simplify your daily routine.

Both units feature the new R-454B refrigerant, a next-generation alternative to R-410A that offers up to 80% lower Global Warming Potential (GWP). This greener choice not only improves energy efficiency but also reduces your environmental impact without sacrificing performance.

The Advantage air handler provides reliable year-round comfort with no need for ductwork, making it a cost-effective option for additions, renovations, or any space where traditional HVAC systems fall short. Its built-in Wi-Fi connectivity allows you to monitor and adjust settings from your smartphone or integrate with Amazon Alexa or Google Assistant for hands-free control. You can also schedule overnight temperature changes to maximize energy savings while you sleep.

Paired with the air handler, the 18K BTU 230V Advantage condenser delivers serious performance, achieving up to a 19.2 SEER2 efficiency rating and an HSPF2-4 of 9.3. Though installation must be handled by an HVAC professional, the process is quick and affordable compared to traditional systems, thanks to its ductless design. Once installed, this system provides consistent, quiet comfort with minimal energy use.

Backed by MRCOOL®’s dependable warranties—including 2 years on parts, 1 year on the compressor, and 1 year on the remote control—you’ll feel confident in your investment. Want even more peace of mind? Enroll in the MRCOOL® Care Program to unlock an optional Limited Lifetime Warranty.
