DIY 4th Gen Multi-Zone 4-Zone 48,000 BTU 21 SEER (9K + 9K + 12K + 12K) Ductless Mini-Split Air Conditioner and Heat Pump

The MRCOOL DIY Multi-Zone 48,000 BTU 21 SEER 4-Zone Ductless Heat Pump Split System is the perfect solution for efficiently heating and cooling up to four rooms in your home. This system includes two 9,000 BTU air handlers, ideal for spaces up to 350 square feet, and two 12,000 BTU air handlers, designed for rooms up to 550 square feet. With a powerful 48,000 BTU condenser, this unit delivers year-round comfort while reducing energy costs. As a heat pump system, it can reverse operation in colder months to pull heat from the outdoors, ensuring warmth even in winter.

Designed with DIY installation in mind, this system requires no professional tools or training. The included Quick Connect lines come pre-charged with eco-friendly R-410A refrigerant, allowing homeowners to complete the setup without hiring an HVAC technician. Step-by-step video guides make the process even easier, so you can get your system up and running quickly.

This 4th Generation MRCOOL DIY Multi-Zone system supports up to five indoor units, offering expandability for additional climate control in the future. Whether you need precise temperature regulation in bedrooms, living spaces, or work areas, this system ensures consistent and efficient performance.

Enjoy smart climate control with the MRCOOL Smart Controller App, compatible with Apple and Android devices. Adjust temperatures, change modes, and monitor system performance from anywhere. The units are also Amazon Alexa and Google Home compatible, enabling hands-free voice control for added convenience. Each air handler features an easy-to-read digital display that shows current settings, system status, and troubleshooting alerts.

The directional airflow control on each indoor unit ensures even distribution of heated or cooled air, keeping every room comfortable. If an emergency cooling situation arises, a manual mode button under the front panel allows for immediate activation. The auto mode function adapts to your preferred temperature settings, adjusting output as needed. For humid climates, the system features a drying mode, which maintains a comfortable temperature while reducing excess moisture.

For energy savings, the sleep mode function operates on an eight-hour cycle, making automatic temperature adjustments to lower energy consumption overnight. Additionally, the timer function allows you to schedule operation times, reducing unnecessary usage and cutting down on utility bills.

Maintenance is simple with built-in alerts and reminders. If refrigerant levels drop, the system will notify you via the display panel. For those who prefer a quieter environment, the mute function disables alert sounds and turns off the LED display, making it ideal for bedrooms or offices. Should a power outage occur, the system automatically restarts with the previous settings when power is restored.
