6 Best Alternatives to the Cooper & Hunter 18K BTU 2-Zone Cassette (2026)

How the alternatives compare to this model

DELLA 27K BTU 2-Zone Ceiling Cassette

The DELLA 27K BTU 2-Zone Cassette offers significantly higher total cooling capacity at 27,000 BTU compared to the Cooper & Hunter’s 18,000 BTU. It splits power unevenly with a 9,000 BTU and a 23,000 BTU unit, whereas the original provides two equal 9,000 BTU zones. This makes the DELLA better suited for larger spaces or rooms with differing heat loads. The DELLA units are much more compact, measuring 22.5 inches square and weighing only 32 pounds, while the Cooper & Hunter is a larger 40-inch square cassette weighing 221 pounds. You should choose the DELLA if you need more raw cooling power and flexible zone sizing, accepting the trade-off of a different physical footprint.

Cooper & Hunter 28,000 BTU 2-Zone Mini Split

This Cooper & Hunter model provides 28,000 BTU of cooling, which is more than the 18,000 BTU cassette. However, it uses wall-mounted units instead of ceiling cassettes. The power split is 9,000 BTU and 18,000 BTU, allowing for one larger zone. It requires 230V power, similar to the original, but the form factor is completely different. The wall-mounted units are heavier at 249 pounds total and share the same 40x48 inch dimensions as the cassette version, likely referring to packaging. If you prefer the traditional wall-mounted look or need higher capacity for a single large room, this is a strong alternative. You give up the concealed ceiling aesthetic and the balanced 9K+9K zone split of the original.

Della 34K BTU Dual Zone Concealed Ducted

The DELLA 34K BTU Dual Zone Concealed Ducted system delivers 34,000 BTU, substantially more than the Cooper & Hunter’s 18,000 BTU. It uses a 9,000 BTU and a 24,000 BTU split, ideal for uneven room sizes. This is a concealed ducted unit, meaning it hides inside walls or ceilings, differing from the visible cassette design. The unit itself is compact at 27.5 inches wide and weighs only 33.1 pounds. It is designed for professional installation in complex layouts. Choose this if you need maximum cooling capacity and a hidden installation style. You sacrifice the visible cassette look and the simpler dual-zone balance of the original Cooper & Hunter model.

BRAVO 30K BTU 2-Zone Cassette

The BRAVO 30K BTU 2-Zone Cassette provides 30,000 BTU of cooling, significantly higher than the 18,000 BTU original. It features a 9,000 BTU and a 24,000 BTU split, offering flexibility for different room sizes. This model highlights a 23 SEER2 efficiency rating, which suggests better energy savings than the standard Cooper & Hunter unit. It retains the 40-inch square cassette form factor, making it a direct physical alternative for ceiling mounting. The BRAVO is heavier and more powerful, suited for larger spaces or those prioritizing energy efficiency. You gain more cooling power and efficiency but lose the equal 9K+9K zone distribution of the original.

Della 27K BTU Dual Zone Soft Airflow

The DELLA 27K BTU Dual Zone Soft Airflow model offers 27,000 BTU, more than the Cooper & Hunter’s 18,000 BTU. It uses a 9,000 BTU and a 12,000 BTU split, providing a more balanced power distribution than other high-capacity alternatives. This unit emphasizes gentle airflow and quiet operation, making it suitable for bedrooms or living areas. It is much lighter at 20.7 pounds and has a different physical profile. If you prioritize comfort and noise reduction over raw cooling power, this is a good choice. You accept a different zone split and a lighter, less robust unit compared to the heavier Cooper & Hunter cassette.

Della 27K BTU 2-Zone Concealed Ducted

The DELLA 27K BTU 2-Zone Concealed Ducted system provides 27,000 BTU, exceeding the 18,000 BTU of the original. It features a 12,000 BTU and a 24,000 BTU split, allowing for a larger primary zone. This is a concealed ducted unit with a 22 SEER2 efficiency rating and includes a condensate pump for complex drainage needs. The unit is compact at 27.5 inches wide and weighs 33.1 pounds. Choose this if you need hidden installation and efficient operation. You give up the visible cassette design and the equal zone balance of the Cooper & Hunter model, opting instead for a concealed, higher-capacity solution.
