MRCOOL DIY Mini Split - 27,000 BTU 3 Zone Ceiling Cassette System (DIY-BC-327HP090909)

Premium Triple-Zone Solution for Balanced Multi-Room Comfort

Transform your property with MRCOOL's perfectly balanced 3-zone ceiling cassette system – the ideal solution for homes with multiple bedrooms or living spaces requiring individualized 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 three distinct spaces – perhaps bedrooms for different family members or a combination of living areas and sleeping quarters – 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 27,000 BTU outdoor condenser featuring exceptional 22 SEER2 and 8.2 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 three identical 9,000 BTU ceiling cassette air handlers, creating a perfectly balanced system that delivers equal comfort to multiple spaces:

  • Three compact 9,000 BTU units each perfectly sized for standard bedrooms, home offices, or medium living areas up to 375 square feet

With this strategic configuration, you can effectively climate-control up to 1,125 square feet of living space across three distinct zones, making it perfect for homes with multiple bedrooms, apartments with separate 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-$4,000 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.

Industry-Leading Energy Efficiency

With an exceptional 22 SEER2 rating, this system stands at the forefront of energy efficiency in its class, delivering outstanding cooling performance while minimizing operational costs. The 8.2 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 balanced 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.

Key Features for Exceptional Performance:
  • Perfect Size Distribution: Three identical 9K BTU units create a perfectly balanced system for multiple similarly-sized rooms
  • Superior Energy Efficiency: Industry-leading 22 SEER2 and 8.2 HSPF-5 ratings deliver exceptional operating economy and reduced utility costs
  • Architectural Integration: Low-profile ceiling cassettes preserve your interior design integrity while delivering powerful performance
  • True DIY Installation: Pre-charged Quick Connect line sets enable confident self-installation without specialized tools or certifications

  • Extreme Weather Performance: Reliable heating even in temperatures as low as -13°F – among the best cold-weather performance in its class
  • Comprehensive Protection: 7-year compressor warranty and 5-year parts warranty ensure lasting peace of mind

The MRCOOL DIY 3-Zone system represents the perfect solution for homeowners seeking efficient climate control with balanced capacity across multiple similarly-sized spaces. Whether you're enhancing a home with multiple bedrooms, creating personalized comfort zones for different family members, or ensuring ideal conditions in a small business with separate offices, this system delivers sophisticated performance with remarkable value across your most important living or working spaces.

Join thousands of satisfied MRCOOL customers who have discovered the perfect balance of comfort, efficiency, and practical innovation.
