The MRCOOL DIY Multi-Zone 48,000 BTU 21 SEER 4-Zone Ductless Heat Pump Split System provides powerful and efficient heating and cooling for up to four rooms, making it an ideal solution for homeowners looking for a cost-effective and customizable climate control system. This setup includes a 48,000 BTU condenser paired with three 9,000 BTU air handlers, each covering up to 375 sq. ft., and one 24,000 BTU air handler, designed for spaces up to 1,100 sq. ft. As a heat pump, this system can reverse operation to pull heat from the outdoors, providing year-round comfort.

Designed for hassle-free, do-it-yourself installation, this MRCOOL DIY Multi-Zone system eliminates the need for expensive professional setup. It features Quick Connect lines that are pre-charged with eco-friendly R-410A refrigerant, making installation fast and simple—no special tools or HVAC technician required. For added convenience, easy-to-follow installation video guides are available, ensuring you can install your system with confidence.

This versatile ductless HVAC solution keeps your home comfortable in every season by cooling in summer, heating in winter, and dehumidifying during humid conditions. You can easily monitor and adjust temperatures in each room using the MRCOOL Smart Controller app, the built-in digital display, or through Amazon Alexa and Google Home voice commands. A wireless remote is also included, giving you multiple ways to control your home’s temperature.

The four MRCOOL DIY Multi-Zone air handlers ensure even airflow distribution with directional control, so every area stays comfortable. Auto Mode allows the system to self-adjust based on your desired temperature, while Dry Mode maintains temperature control while reducing humidity. The Sleep Mode feature helps conserve energy by gradually adjusting the temperature over an 8-hour period, and the timer function lets you schedule heating and cooling to match your lifestyle, helping you reduce energy consumption and lower utility costs. If you prefer a quiet, undisturbed environment, the mute function turns off alerts and dims the LED display.

Maintenance is simple with built-in alerts and reminders. Troubleshooting codes appear on the air handler display for quick issue diagnosis, and the system provides automatic air filter cleaning alerts to ensure optimal performance. If the refrigerant level drops, the system will notify you with a low refrigerant alert, helping you detect any potential leaks early. In the event of a power outage, the MRCOOL system automatically resumes operation with the same settings once power is restored.
