MRCOOL DIY Mini Split - 30,000 BTU 2 Zone Ceiling Cassette System (DIY-BC-236HP1218)

Premium Dual-Zone Solution with Significant Capacity Reserve

Transform your property with MRCOOL's strategically engineered 2-zone ceiling cassette system – the perfect solution for open-concept homes or properties with one medium and one large living space requiring powerful, customized climate control. This expertly designed 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 both your main living area and primary bedroom suite – each with precisely matched cooling and heating capacity for their specific dimensions – 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.

What distinguishes this premium system is its robust 36,000 BTU outdoor condenser paired with just 30,000 BTU of indoor capacity – a commercial-grade powerhouse that provides significant capacity reserve and operational headroom even when both zones demand maximum output simultaneously. With exceptional 21.5 SEER2 and 8.5 HSPF-5 efficiency ratings, this system delivers substantial energy savings while ensuring uncompromising performance during peak demand periods. 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 Contemporary Living

This thoughtfully designed package includes a strategic mix of ceiling cassette air handlers specifically configured for modern living:

  • One mid-sized 12,000 BTU unit ideally matched to a primary bedroom suite or medium living area up to 500 square feet
  • One powerful 18,000 BTU unit designed for a great room, open-concept living area, or large master suite up to 750 square feet

With this strategic configuration, you can effectively climate-control up to 1,250 square feet of living space across two distinct zones, making it perfect for modern condos, apartments, or smaller homes with an open floor plan plus one larger private space requiring individualized comfort control.

Enhanced Capacity Reserve for Superior Performance

Unlike systems with precisely matched condenser-to-handler ratios, this premium package features a substantial 6,000 BTU capacity reserve, ensuring exceptional performance even during the most demanding conditions. This extra headroom allows each zone to maintain perfect comfort levels regardless of solar gain, occupancy changes, or extreme weather challenges that would strain lesser systems. When both zones demand maximum cooling or heating simultaneously, the additional capacity provides critical operational flexibility that ordinary systems simply cannot match.

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 $1,500-$3,000 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 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.

  • Premium Capacity Design: Oversized 36,000 BTU condenser provides significant operational headroom for superior performance during peak demand
  • Strategic Configuration: Perfect for properties with one medium and one large living space requiring individualized climate control
  • Superior Energy Efficiency: 21.5 SEER2 and 8.5 HSPF-5 ratings deliver exceptional operating economy despite the substantial capacity
