MRCOOL DIY Mini Split - 30,000 BTU 3 Zone Ceiling Cassette System (DIY-BC-336HP090912)
Premium Triple-Zone Solution for Mixed-Size Spaces
Transform your property with MRCOOL's perfectly balanced 3-zone ceiling cassette system – the ideal solution for homes with multiple rooms requiring individualized climate control across various room sizes. 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 three distinct spaces – perhaps two bedrooms plus a main living area, each with precisely matched cooling and heating capacity for their specific dimensions and usage patterns. 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 space.
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 superior 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.
Perfect Balance for Modern Multi-Room Living
This thoughtfully designed package includes a strategic mix of ceiling cassette air handlers specifically configured for modern living patterns:
Two compact 9,000 BTU units perfect for standard bedrooms or home offices up to 375 square feet each
One mid-sized 12,000 BTU unit designed for a living room, open kitchen, or medium-sized common area up to 500 square feet
With this strategic configuration, you can effectively climate-control up to 1,250 square feet of living space across three distinct zones, making it perfect for modern homes with varying room sizes, apartments with diverse living areas, or small businesses requiring individualized comfort control in different spaces.
Architectural Integration for Design Excellence
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.
Revolutionary DIY Installation Saves Thousands
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-$4,500 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.
Powerfully Sized for Versatile Comfort
This robust system provides the perfect balance of power and efficiency for medium-sized homes or living spaces with diverse cooling and heating needs. The total system capacity of 30,000 BTU delivers ample conditioning power for up to 1,250 square feet of living space, with the flexibility to tailor output to each zone's specific requirements. The thoughtful distribution of capacity – with two smaller units for personal spaces and one larger unit for common areas – ensures each room receives precisely the right amount of conditioning power without waste or inefficiency.
Industry-Leading Energy Efficiency
With an exceptional 21.5 SEER2 rating, this system stands at the forefront of energy efficiency in its class, delivering outstanding cooling performance while minimizing operational costs. The impressive 8.5 HSPF-5 heating efficiency further enhances year-round energy savings, ensuring your comfort doesn't come at the expense of high utility bills. These industry-leading efficiency ratings make this system an environmentally responsible choice that pays dividends through years of reduced energy consumption.
Superior Zoning Flexibility
The mixed-capacity three-zone design offers unprecedented flexibility for modern living. Each zone operates independently, allowing personalized temperature settings for different family members, time-of-day usage patterns, or varying comfort preferences. This intelligent approach to climate control ensures efficient operation by delivering cooling and heating only where and when needed, eliminating the energy waste of traditional whole-house systems that condition unoccupied spaces.
Industry-Leading Cold Weather Performance
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.
Complete Control at Your Fingertips
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. Create personalized comfort schedules, adjust settings remotely, and monitor performance – all from a simple, user-friendly interface that puts complete control in your hands whether you're home or away.
