This compact 9,000 BTU ceiling cassette unit represents an ideal entry point for homeowners seeking efficient climate control in smaller spaces. The system operates on 208-230V power and carries both ETL Intertek approval and AHRI certification, ensuring reliable performance and safety standards.

The unit features Whisper Technology for exceptionally quiet operation, making it perfect for bedrooms, home offices, or living areas where noise levels matter. With heating capability down to -13°F ambient temperature, this system provides year-round comfort in most climates.

Installation becomes straightforward with the included 16-foot installation kit, which contains pre-flared and insulated copper line sets, communication wires, and essential accessories. The 16-foot drainage extension accommodates various ceiling configurations and ensures proper condensate removal.

This model excels in spaces requiring focused climate control without the complexity of multi-zone systems. The ceiling-mounted design preserves wall space while delivering even air distribution throughout the room.

Cooper & Hunter One Way Ceiling Cassette

Product Image

The 18,000 BTU one-way ceiling cassette introduces a revolutionary approach to ceiling-mounted climate control with its minimalist design philosophy. This unit features a discreet one-way airflow pattern that seamlessly integrates with modern interior aesthetics while maintaining optimal air distribution.

Designed specifically for smaller spaces and tight ceiling configurations, this cassette fits perfectly between structural ceiling beams where traditional four-way units might not accommodate. The smart wall thermostat provides intuitive control over temperature settings and operational modes.

The system maintains the same robust specifications as other Cooper & Hunter models, including operation down to -13°F for heating applications. ETL Intertek approval and AHRI certification guarantee performance standards and safety compliance.

Installation convenience comes through the complete 25-foot installation kit, featuring pre-flared copper lines and all necessary accessories. The one-way design reduces installation complexity while providing effective climate control for targeted areas.

Cooper & Hunter Dual Zone System

Product Image

This 18,000 BTU dual zone configuration combines two 9,000 BTU ceiling cassettes with a single outdoor unit, offering independent temperature control for separate areas. The multi-zone approach maximizes energy efficiency while providing customized comfort in different rooms or zones.

Each cassette operates independently, allowing occupants to set different temperatures based on individual preferences or usage patterns. This flexibility proves particularly valuable in homes with varying sun exposure, occupancy levels, or functional requirements across different spaces.

The system includes comprehensive installation kits for both indoor units, featuring 25-foot pre-flared copper line sets, communication wiring, and drainage extensions. Professional installation ensures optimal performance and warranty compliance.

Whisper Technology maintains quiet operation across both units, while the robust heat pump functionality provides reliable heating performance down to -13°F ambient temperatures. The dual zone configuration often represents better value than installing separate single-zone systems.

Cooper & Hunter Tri Zone System

Product Image

The 28,000 BTU tri-zone system represents advanced climate control technology with three 9,000 BTU ceiling cassettes connected to a single outdoor unit. This configuration delivers exceptional energy efficiency with a 24.6 SEER2 rating, significantly reducing operational costs.

Three independent zones allow precise temperature control across multiple rooms, making this system ideal for larger homes, apartments, or commercial applications. Each zone operates independently, optimizing energy consumption by conditioning only occupied spaces.

The system includes complete installation kits for all three indoor units, with 25-foot copper line sets, communication wires, and drainage accessories. The comprehensive package simplifies professional installation while ensuring proper system operation.

Advanced inverter technology automatically adjusts compressor speed based on cooling or heating demands, maintaining consistent temperatures while minimizing energy consumption. The tri-zone approach often proves more cost-effective than multiple single-zone installations.

Cooper & Hunter 36,000 BTU Single Zone

Product Image

This high-capacity 36,000 BTU ceiling cassette delivers maximum cooling and heating power for larger spaces or commercial applications. The Sophia Series represents Cooper & Hunter’s premium line, offering enhanced performance and refined engineering.

The substantial capacity handles spaces up to 1,500 square feet effectively, making it suitable for large living areas, commercial offices, or open-concept homes. Despite its high output, Whisper Technology maintains exceptionally quiet operation.

Professional-grade construction includes ETL Intertek approval and AHRI certification, ensuring reliable performance in demanding applications. The system operates efficiently in heating mode down to -13°F ambient temperatures.

The included installation kit provides essential components for professional setup, though the high-capacity system typically requires experienced HVAC technicians for optimal installation and performance. The wall thermostat offers intuitive control over all system functions.

Buying Guide

Capacity Selection represents the most critical decision when choosing ceiling cassette mini splits. Calculate your space’s cooling load using 20-25 BTU per square foot as a general guideline, though factors like ceiling height, insulation, window area, and sun exposure significantly affect requirements. Oversized units cycle on and off frequently, reducing efficiency and comfort.

Zone Configuration determines system flexibility and installation costs. Single-zone systems work well for individual rooms or open areas, while multi-zone systems provide independent control for different spaces. Consider your home’s layout, usage patterns, and family preferences when selecting zone configurations.

SEER2 Ratings indicate energy efficiency, with higher numbers representing better performance. Modern ceiling cassettes typically range from 16-25 SEER2, with premium models offering superior efficiency. Higher SEER2 units cost more initially but provide significant energy savings over their lifespan.

Installation Requirements vary based on system complexity and existing infrastructure. Ceiling cassettes require adequate ceiling space, structural support, and drainage provisions. Professional installation ensures proper refrigerant charging, electrical connections, and warranty validity. Consider installation costs when comparing different systems.

Noise Levels become particularly important for ceiling-mounted units in living spaces or bedrooms. Look for systems with advanced noise reduction technology and low decibel ratings. Quality units operate at 19-25 dB, comparable to a whisper or rustling leaves.

Climate Considerations affect system selection in regions with extreme temperatures. Verify the unit’s heating capacity at your area’s lowest expected temperatures. Cold-climate heat pumps maintain efficiency below 0°F, while standard units may require backup heating in severe cold.
