You can compare these options to find the best fit for your specific electrical setup and room layout.
How each alternative compares
Della 35K BTU 4 Zone Mini Split
The Della 35K BTU 4 Zone Mini Split reduces total cooling capacity to 35,000 BTU from the original 45,000 BTU. It keeps the same 19 SEER2 efficiency rating and Alexa connectivity. The zone configuration shifts to 9K+9K+12K+12K units. This lower capacity suits smaller spaces under 1900 square feet. You give up raw power for a system better matched to modest layouts. The outdoor condenser dimensions remain nearly identical. This model works well if your home does not require the full 45,000 BTU output. It maintains the same quad-zone control structure. You retain individual room management while using less energy for smaller areas.
Senville 48K BTU Quad Zone Mini Split
The Senville 48K BTU Quad Zone Mini Split offers higher efficiency at 23 SEER2 compared to the original 19 SEER2. It provides 48,000 BTU of cooling across four 12,000 BTU indoor units. The original uses mixed capacities of 9K, 12K, and 18K. This Senville unit features Wi-Fi smart control instead of Alexa-only connectivity. It operates on 230V power. The outdoor unit is heavier at 36 pounds. You gain better energy efficiency and more uniform zone capacities. You lose the flexible room-specific sizing of the original. This option fits large spaces needing strong heating and precise digital management. It is ideal for users who prefer app-based control over voice assistant integration.
DELLA 35K BTU 4-Zone Ceiling Cassette
The Della 35K BTU 4-Zone Ceiling Cassette uses a different form factor. It installs into ceilings rather than hanging on walls. The total capacity is 35,000 BTU with zones of 9K+9K+9K+18K. It shares the quad-zone structure but lacks explicit efficiency ratings in the provided data. The outdoor unit is lighter at 32 pounds. You trade wall-mounted visibility for hidden ceiling integration. This suits commercial spaces or homes where aesthetics matter more than raw BTU count. The original offers 45,000 BTU for larger areas. This cassette model provides discreet climate control. You get a streamlined look but accept lower total cooling power. It is a practical choice for quiet environments requiring unobtrusive hardware.
BRAVO 42K BTU 4-Zone Cassette
The BRAVO 42K BTU 4-Zone Cassette also uses ceiling-mounted units. It provides 42,000 BTU across 9K+9K+9K+12K zones. The original Della offers 45,000 BTU with wall units.

The indoor units are larger, measuring 40 by 40 inches. This system fits complex layouts needing high-efficiency ceiling integration. It suits commercial or high-end residential projects. You prioritize app-based zone management over maximum cooling output. The trade-off is lower total BTU for better individual room control. It is a strong option for users who need detailed digital oversight of each zone.
Della 42K BTU 4-Zone Mini Split
The Della 42K BTU 4-Zone Mini Split offers 42,000 BTU, slightly less than the original 45,000 BTU. It maintains quad-zone control with a 9K+9K+18K+18K configuration. The original uses 9K+12K+12K+18K. This model includes app control for remote management. You gain modern smart features but lose some total capacity. The outdoor unit is slightly taller at 12.1 inches. It fits buyers who prioritize energy savings and remote access. You accept lower peak cooling power for better digital integration. The capacity mismatch limits use in high-demand scenarios. This unit works well for multi-room homes needing app control. You get efficient operation with flexible zone management. It is a practical alternative for those valuing connectivity over maximum BTU output.
Garvee 4 Zone 35000 BTU Mini Split
The Garvee 4 Zone 35000 BTU Mini Split provides 35,000 BTU across four equal zones. The original Della offers 45,000 BTU with varied capacities. This Garvee unit features Wi-Fi smart control.
