MRCOOL DIY Mini Split - 36,000 BTU 3 Zone Ceiling Cassette System (DIY-BC-336HP090918)

Transform your property with MRCOOL's expertly balanced 3-zone ceiling cassette system – the ideal solution for homes with one standard bedroom and two large living areas requiring powerful, customized climate control. This thoughtfully engineered package delivers sophisticated comfort with an elegant, space-saving design that enhances your interior aesthetic while providing the revolutionary DIY simplicity that has made MRCOOL the preferred choice for discerning homeowners.

Imagine maintaining ideal temperatures in a bedroom plus two substantial living spaces – such as an open-concept kitchen/dining area and a spacious family room – all while preserving your interior design with sleek, ceiling-mounted units that virtually disappear overhead. No bulky wall units consuming valuable wall space, no complicated ductwork requiring major renovation – just efficient, whisper-quiet comfort flowing discreetly from above in perfectly sized units for each unique living area.

At the heart of this system is a high-performance 36,000 BTU outdoor condenser featuring exceptional 21.5 SEER2 and 8.5 HSPF-5 efficiency ratings, delivering substantial energy savings while providing precise zone control. The specialized Gold Fin® condenser coating ensures exceptional durability even in coastal environments, while industry-leading heating performance down to -13°F guarantees year-round comfort regardless of extreme weather conditions.

This thoughtfully designed package includes a specialized mix of ceiling cassette air handlers configured for contemporary homes with primarily large, open living spaces:

• One compact 9,000 BTU unit perfect for a standard bedroom or home office up to 375 square feet
• Two powerful 18,000 BTU units designed for substantial living areas, great rooms, or open-concept spaces up to 750 square feet each

With this strategic configuration, you can effectively climate-control up to 1,875 square feet of living space, making it perfect for modern homes with open floor plans that prioritize large, communal living areas while still accommodating a private bedroom or office space with individualized comfort control.

Each ceiling cassette installs discreetly between standard 16" ceiling joists, creating a clean, professional appearance that enhances any interior design. The modern, low-profile units deliver multi-directional airflow for even temperature distribution while maintaining architectural integrity – no obtrusive wall units to disrupt your design vision, just perfect comfort radiating invisibly from above in each space.

What truly distinguishes MRCOOL is the groundbreaking pre-charged Quick Connect Line Set technology. These specialized copper lines arrive pre-filled with refrigerant, eliminating the need for vacuum pumps, specialized equipment, or certified technicians. This innovation means you can confidently install a professional-grade multi-zone system yourself, saving $2,000-$4,000 in professional installation costs while achieving the same premium performance.

The user-friendly design guides you through each step of the process – from mounting the indoor and outdoor units to connecting the pre-charged lines using simple hand tools. Within a weekend, you'll have implemented a sophisticated climate solution that would typically require significant professional labor, scheduling delays, and premium costs.

Unlike standard heat pumps that struggle in frigid conditions, MRCOOL's advanced technology delivers reliable heating performance even when outdoor temperatures plummet to an astonishing -13°F – among the best cold-weather capabilities in the industry. This exceptional performance eliminates the need for expensive backup heating systems in all but the most extreme climate regions, providing true year-round comfort and significant operational savings.

Take command of your environment with the intuitive SmartHVAC app, allowing you to manage temperatures in each zone independently from anywhere using your smartphone or tablet.
