6 Best Alternatives to the Della 18K BTU 2 Zone (2026)

Comparing key specs and features

DELLA 28K BTU Dual Zone Mini Split

This Della model ups the total capacity to 28,000 BTU with a 9K and 18K indoor unit split. It keeps the same 22 SEER2 efficiency rating and smart app control found in the original 18K unit. The higher output suits larger rooms or open floor plans where the standard 18K version might struggle. You get independent zone management for two areas, just like the reference model. The main trade-off is increased physical size and weight. The outdoor unit is slightly larger, and the indoor units differ in dimensions. If your space exceeds 850 square feet or has high heat loads, this higher-capacity option provides better comfort without sacrificing energy efficiency or smart connectivity.

BRAVO 18K 2-Zone Ceiling Cassette

The Bravo ceiling cassette offers a discreet installation method by mounting into your ceiling rather than on the wall. It provides 18,000 BTU of cooling across two 9K zones, matching the total capacity of the Della 18K. It shares the same 22 SEER2 efficiency rating and smart app control features. This unit requires 208-230V power, similar to the Della, but the installation is more complex due to the ceiling mount design. You gain a cleaner aesthetic with hidden units, which is ideal for finished spaces. However, you lose the ease of wall-mounted maintenance and access. Choose this if you prioritize a minimalist look and have the ceiling space for a cassette system, accepting a more involved setup process.

BRAVO 18K 2-Zone Concealed Ducted Mini Split

This Bravo concealed ducted mini split hides entirely within your ceiling or wall cavities. It delivers 18,000 BTU across two 9K zones with a 22 SEER2 efficiency rating. Like the Della 18K, it supports smart app control and independent zone management. The primary difference is the installation type. You must connect it to existing ductwork or design a duct system, which is a significant step up from the Della’s straightforward wall mount. This option is best for homeowners who want zero visible indoor units. You give up the easy access and lower installation complexity of the Della. If you are renovating and want a completely invisible climate control solution, this concealed model is the practical choice despite the higher installation effort.

BRAVO 18K BTU 2-Zone Floor/Ceiling Mini Split

The Bravo floor/ceiling unit offers flexible mounting options, allowing you to install it near the floor or ceiling. It provides 18,000 BTU across two 9K zones with a 22 SEER2 rating. Smart app control is included, matching the Della 18K’s connectivity. This model is ideal for open layouts or basements where wall space is limited or awkwardly shaped. You get the same efficiency and smart features but with a different physical form factor. The unit is larger in width and height compared to the Della’s compact indoor heads. This flexibility allows for better air distribution in unique room shapes. If your space has unconventional dimensions or you need to preserve wall space, this versatile mounting option provides a functional alternative without losing efficiency or smart control.

ROVSUN 38000 BTU Dual Zone Mini Split

The RVSUN model significantly increases cooling capacity to 38,000 BTU with a 35K and 24K zone split. It operates on 230V power like the Della 18K but drops the efficiency rating to 20 SEER2. This trade-off gives you raw power for larger spaces or commercial areas. The unit is much heavier and larger, weighing 222 pounds compared to the Della’s lighter components. You gain substantial cooling output for high-heat environments but lose the superior energy efficiency of the 22 SEER2 Della. Smart features are not explicitly detailed in the provided specs, so assume basic control. Pick this if you need to cool a large area quickly and prioritize capacity over maximum energy savings or compact size.

TOSOT 30k BTU 2-Zone Mini Split

The Tosot 30K BTU 2-Zone Mini Split offers higher capacity with a 12K and 18K zone split. It maintains a strong 21 SEER2 efficiency rating, slightly lower than the Della’s 22 SEER2 but still very efficient. The indoor units are larger in dimension, particularly in width and height. You get smart control and dual-zone management similar to the Della. The key difference is the power connection; you must supply your own power cord, whereas the Della includes standard installation kits. This model suits larger homes needing more than 18,000 BTU but who still value high efficiency. You trade a small amount of SEER2 points for significantly more cooling power. If your space is larger than 850 square feet and you can handle the power cord setup, this is a robust alternative.
