DIY Installation, Simplified
The MRCOOL DIY Ceiling Cassette is designed to fit standard 16-inch joist centers, making installation easier and more accessible for homeowners. These units are engineered for true DIY installation, with pre-charged line sets and a detailed step-by-step guide that walks you through every stage — from mounting the cassette to connecting the outdoor condenser and setting up smart controls.
💡 Tip: Before you begin, double-check your ceiling joist spacing and ensure you have adequate clearance for the unit. Plan your condensate drain route carefully to ensure smooth, reliable operation once installed.
Sleek, Minimalist Style
Unlike window units or bulky wall mounts, cassette systems sit nearly flush with the ceiling, preserving sightlines and wall space for furniture, art, or shelving. The modern grille complements contemporary, traditional, and transitional interiors.
Quiet, Powerful, and Efficient
Enjoy consistent cooling with low sound levels that won’t disrupt sleep, calls, or movie night. Smart temperature control and inverter technology (on compatible models) help reduce energy consumption while keeping comfort steady.
Zoned Cooling for the Way You Live
The MRCOOL DIY Single-Zone Ceiling Cassette is available in an 18K BTU size, perfectly matched with its 230V outdoor condenser for reliable, efficient operation.
For larger homes or expanded comfort, the Multi-Zone system allows you to combine multiple ceiling cassettes or wall-mounted air handlers — available in 6K, 9K, 12K, and 18K BTU capacities — giving you complete flexibility to customize your comfort by room.
Install cassettes where you need them most — bedrooms, offices, or living areas — and enjoy true zoned temperature control. Each space can be adjusted independently to eliminate hot and cold spots, reduce wasted energy, and deliver personalized comfort throughout your home.
Eco-Forward Choice
MRCOOL DIY systems are designed to work with modern, lower-GWP refrigerants and efficient components—an excellent step toward lowering your home’s environmental impact.
