MRCOOL DIY Mini Split - 18,000 BTU 2 Zone Ceiling Cassette System

Transform your clients' smaller properties with MRCOOL's perfectly balanced dual-zone ceiling cassette system. This precision-engineered 18,000 BTU solution delivers sophisticated comfort across two compact living spaces with architectural elegance, paired with the revolutionary DIY installation that will significantly increase your sales potential in the growing small-space market segment.

Your clients will immediately visualize:

  • Perfect climate control across two matched smaller living areas
  • Sleek, architecturally integrated ceiling units that disappear into the ceiling
  • Independent smartphone control for personalized comfort in each zone
  • Thousands saved on professional installation costs

The efficient 18K BTU outdoor condenser works seamlessly with dual 9K BTU indoor cassettes to deliver exceptional 21.2 SEER2 efficiency while the Gold Fin® coating ensures remarkable durability - particularly valuable for your clients in coastal environments where corrosion protection is essential.

Perfect Configuration for Compact Living Spaces

This system addresses the rapidly growing market for efficient climate solutions in smaller homes, apartments, and ADUs (accessory dwelling units). Your clients get two precisely matched 9K BTU ceiling cassettes, each perfectly sized to manage up to 375 square feet of living space.

With this symmetrical configuration, you're offering a solution that effectively climate-controls up to 750 square feet of living space across two distinct zones - perfect for smaller homes, apartments, tiny homes, or renovation projects requiring efficient zoned comfort in compact spaces.

Revolutionary DIY Installation Expands Your Business Potential

While your competitors struggle with installation backlogs and often decline smaller projects as "unprofitable," you'll deliver MRCOOL's game-changing pre-charged Quick Connect technology - empowering your clients to handle installation themselves using basic tools.

This innovation dramatically increases your inventory turnover in the rapidly growing small-space market segment. Your clients save $1,800-$3,000 on professional installation while you maintain higher customer satisfaction and faster inventory cycles - a true competitive advantage in a market segment many competitors ignore.

Key Benefits That Drive Sales:

  • Perfectly Sized Zones: Dual 9K BTU units deliver ideal performance for smaller adjacent living spaces
  • Architectural Excellence: Low-profile ceiling cassettes preserve interior design integrity in compact areas
  • Premium Efficiency: Industry-leading 21.2 SEER2 rating delivers substantial operational savings
  • Cold Weather Performance: Reliable heating down to -13°F eliminates backup system requirements
  • Intelligent Control: Complete smartphone management with zone-specific scheduling
  • Premium Protection: Industry-leading 7-year compressor and 5-year parts warranties

Position your business as the forward-thinking HVAC supplier that delivers precisely what today's small-space market demands. The MRCOOL DIY dual 9K BTU system provides the perfect balance of power, efficiency and architectural integration for compact residential applications, while eliminating the installation complications that traditionally make smaller projects unprofitable for your competitors.

This perfectly balanced system represents the ideal solution for clients with modest space conditioning needs who demand both performance and design excellence - all with the DIY simplicity that has made MRCOOL the fastest-growing brand in the residential HVAC market.
