DIY 4th Gen Multi-Zone 5-Zone 48,000 BTU 21 SEER (9K + 9K + 9K + 12K + 12K) Ductless Mini-Split Air Conditioner and Heat Pump

The MRCOOL DIY Multi-Zone 48,000 BTU 21 SEER 5-Zone Ductless Heat Pump Split System provides efficient heating and cooling for up to five rooms, offering a customizable, energy-saving climate control solution. Powered by a 48,000 BTU condenser, this system includes three 9,000 BTU air handlers (ideal for areas up to 350 sq. ft. each) and two 12,000 BTU air handlers (covering up to 500 sq. ft. each). As a heat pump system, it not only cools during summer but also reverses operation to pull in heat from the outdoors, keeping your home warm during winter.

The MRCOOL DIY 4th Gen Multi-Zone system is designed for easy, do-it-yourself installation, eliminating the need for special tools or professional HVAC technicians—saving you thousands on installation costs. It features Quick Connect lines pre-charged with eco-friendly R-410A refrigerant, making setup simple and hassle-free. To make installation even easier, step-by-step instructional videos are available to guide you through the process.

This versatile system operates year-round, providing cooling in summer, heating in winter, and dehumidification during humid seasons. You can monitor and adjust room temperatures using the MRCOOL Smart Controller app, the digital display on each air handler, or through Amazon Alexa and Google Home voice commands. A wireless remote is also included for added convenience.

Each of the five air handlers is equipped with directional airflow control, ensuring even air distribution for maximum comfort in every room. If forced cooling is needed, you can activate manual operation mode for system testing or emergency use. In auto mode, the unit intelligently adjusts airflow based on your desired temperature, while the drying function effectively controls humidity levels.

For energy efficiency, Sleep Mode gradually adjusts the temperature over an 8-hour cycle, while the programmable timer allows you to customize heating and cooling schedules to optimize energy consumption. The troubleshooting display provides error codes and maintenance alerts, including low refrigerant warnings and filter cleaning reminders, ensuring your system stays in peak condition. In the event of a power outage, the system automatically restarts with its previous settings. To reduce noise and distractions, the mute function disables alerts and turns off the LED display.

The MRCOOL DIY Multi-Zone 48,000 BTU 21 SEER 5-Zone Ductless Heat Pump Split System is a high-performance, easy-to-install HVAC solution that offers customizable, smart climate control—perfect for homeowners looking for efficient, year-round comfort with DIY convenience.
