With a 48,000 BTU condenser, this system includes three 18,000 BTU air handlers, each covering up to 800 sq. ft., providing even and customizable airflow throughout your home.

As a heat pump system, it operates in reverse during colder months, efficiently pulling in heat from the outside air to warm your space. This ductless HVAC solution ensures year-round temperature control while maintaining energy efficiency.

Designed for hassle-free installation, the MRCOOL DIY Multi-Zone system includes Quick Connect line sets that are pre-filled with R-410A refrigerant, eliminating the need for an HVAC technician.

Each indoor air handler features a digital display that provides real-time temperature readings, troubleshooting codes, and system alerts to keep you informed of any performance issues. Operate each unit wirelessly using the included remote control or directly from your smartphone.

The directional airflow system ensures even distribution of heated or cooled air, creating consistent comfort across all zones. In auto mode, the system automatically adjusts its settings based on your desired temperature. Sleep mode helps reduce energy consumption at night, optimizing efficiency while maintaining a comfortable sleeping environment.

For added convenience, the dehumidification function removes excess moisture from the air, improving indoor air quality and preventing mold and mildew growth. In situations where immediate cooling is needed, the emergency operation mode allows manual activation using the button located under the unit’s front panel.

Maintenance is simple, thanks to automatic alerts for air filter cleaning and refrigerant levels. If a leak is detected, a warning will appear on the front display of each air handler. Additionally, users can mute alerts to reduce noise and minimize LED lighting, making it ideal for bedrooms or quiet spaces. In the event of a power outage, the system automatically resumes operation with its previous settings once power is restored.
