This intelligently designed 39,000 BTU package delivers sophisticated climate control 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, living room, and great room – 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.

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 graduated mix of ceiling cassette air handlers specifically configured for homes with varying room dimensions:

• One compact 9,000 BTU unit perfect for a standard bedroom or office up to 375 square feet
• One mid-sized 12,000 BTU unit ideally matched to a living room or primary bedroom up to 500 square feet
• One powerful 18,000 BTU unit designed for a great room, open-concept living area, or master suite up to 750 square feet

With this strategic configuration, you can effectively climate-control up to 1,625 square feet of living space across three distinct zones, making it perfect for modern homes with open floor plans or properties requiring customized temperature zones of significantly different sizes.

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.
