Some buyers prefer equal zone sizes or smart app control that this model does not explicitly list.
This list of 6 options was chosen because their specifications overlap with the original unit. You will find systems with higher BTU outputs, different voltage requirements like 230V, or varied zone configurations. Each alternative offers a distinct combination of efficiency, size, and features. You can compare these specs to find the best fit for your specific home layout and power supply needs.
Our top pick: DELLA 35K BTU 4-Zone Ceiling Cassette.
How each alternative compares
Senville 48K BTU Quad Zone Mini Split
The Senville 48K BTU Quad Zone offers four equal 12,000 BTU zones, unlike the Della 35’s mixed 9k and 18k setup. It provides a higher 23 SEER2 efficiency rating and includes Wi-Fi smart control, which the Della lacks. The indoor units are smaller, measuring 15 by 16 inches, compared to the Della’s 22.5-inch square cassettes. This model runs on 230V power. It is ideal for homes needing uniform cooling across four rooms rather than varied zone sizes. You get better efficiency and app control, but you lose the ceiling-mounted aesthetic and the specific 35k BTU total capacity.
DELLA 45K BTU 4 Zone Mini Split
The Della 45K BTU 4-Zone system provides more total cooling power with 45,000 BTUs, compared to the 35,000 BTUs of the original. It uses a wall-mount format instead of a ceiling cassette, changing the installation requirements entirely. The efficiency drops to 19 SEER2, which is lower than the Della 35’s 22.5 SEER2. However, it includes Alexa integration for voice control, a feature absent in the cassette model. The indoor units are smaller and less obtrusive than the large ceiling cassettes. This option suits users who need higher capacity and smart voice control, accepting lower efficiency and a different mounting style.
BRAVO 42K BTU 4-Zone Cassette
The BRAVO 42K BTU 4-Zone Cassette features a different zone configuration of 9k, 9k, 9k, and 12k units. It maintains a ceiling-mounted design similar to the Della 35. The indoor units are significantly larger, measuring 40 by 40 inches, compared to the Della’s 22.5-inch cassettes. This model does not list a SEER2 rating in the provided data, so efficiency comparisons are limited. It is positioned as a premium option with strong zone control. You get a robust ceiling-mounted solution for multi-room environments. The trade-off is the much larger physical footprint of the indoor units and the lack of specified efficiency metrics.
Della 42K BTU 4-Zone Mini Split
The Della 42K BTU 4-Zone Mini Split offers a higher total capacity of 42,000 BTUs, exceeding the 35,000 BTU of the original. It uses a wall-mount design rather than a ceiling cassette. The efficiency rating is not explicitly stated in the data, but it is described as offering strong efficiency. This model includes smart app management, which the Della 35 cassette lacks. The indoor units are smaller and more compact than the large ceiling cassettes. This alternative suits buyers who need precise zone control and app integration for larger spaces. You gain capacity and smart features but lose the concealed ceiling installation and the specific 22.5 SEER2 rating.
Della 55K BTU 4 Zone Mini Split
The Della 55K BTU 4-Zone Mini Split provides significantly higher capacity with 55,000 BTUs, compared to the 35,000 BTU original. It uses a wall-mount format instead of a ceiling cassette. The efficiency is not specified in the data, but the model is noted for high capacity and cold-weather heating performance. The indoor units are smaller and less visible than the large ceiling cassettes. This option fits large homes with distinct zone requirements. You get more cooling power and a different mounting style. The trade-off is the lack of specified efficiency metrics and the loss of the specific 22.5 SEER2 rating found in the Della 35 cassette.
DELLA 34K BTU 4-Zone Ducted Mini Split
The Della 34K BTU 4-Zone Ducted Mini Split offers a total capacity of 34,000 BTUs, slightly less than the 35,000 BTU original. It uses a ducted design with a built-in condensate pump, unlike the cassette model. The efficiency rating is not listed in the data. This model includes smart app control, which the Della 35 lacks. The indoor units are smaller, measuring 27.5 by 19.3 inches. It is ideal for concealed installations under 1500 square feet. You get a hidden aesthetic and app control. The trade-off is lower total capacity and the specific ducted installation requirements, which differ from the ceiling cassette setup.
