The MRCOOL DIY Multi-Zone 4th Gen 36K BTU Three-Zone Ductless Mini Split (9K + 9K + 18K) offers an efficient, easy-to-install heating and cooling system for three zones in your home. This DIY-friendly HVAC system features ceiling cassettes that blend seamlessly into your ceiling, providing unobtrusive climate control without using wall space or ductwork. With easy, low-profile installation, these cassettes are compatible with various joist types, making them ideal for both new builds and retrofits.
The cassettes work with the MrCool® DIY® Quick Connect® Line Set and No-Vac® Coupler, making installation a breeze by extending the line set length without requiring professional tools. These cassettes also feature an Elevation function for easy filter maintenance. Plus, the system operates quietly, offering multiple modes for year-round comfort.
This system can heat and cool three rooms, with two 9K BTU units for spaces up to 375 sq ft and one 18K BTU unit for areas up to 750 sq ft. The system includes pre-charged Quick Connect lines filled with eco-friendly R-410A refrigerant, eliminating the need for an HVAC technician. The 36K BTU condenser can support up to four indoor units, providing flexibility for future expansions.
With smart controls, you can operate the system via the MRCOOL Smart Controller mobile app, or integrate with Amazon Alexa or Google Home. The digital display on each indoor air handler provides real-time temperature and system information, while alert codes ensure you're always informed.
This system is backed by a 7-year compressor warranty (with an optional lifetime warranty) and a 5-year parts warranty, ensuring long-lasting performance and peace of mind.
