This original model uses a 9+9+9+18 BTU split, which suits homes needing one larger room cooled. Other buyers may prefer four equal 9K BTU zones for balanced coverage across multiple spaces. You might also seek better cold-climate heating performance or a wall-mounted unit instead of a concealed ducted design. We selected these alternatives because their specifications overlap with the original product. Each option shares the quad-zone architecture and similar total BTU output. However, they differ in efficiency, voltage, and indoor unit sizing. This list compares seven systems to help you find the right fit. You can review the specs to match your specific cooling needs and installation constraints. The following sections break down each model's capabilities.
Our top pick: Della 34K BTU 4-Zone Ducted Mini Split.
How each alternative compares
ROVSUN 38000 BTU Quad Zone Mini Split
The ROVSUN model provides four equal 9K BTU indoor units, whereas the Della uses three 9K units and one larger 18K unit. You get 38,000 total BTU here, which is slightly more than the Della’s 34,000 BTU. Both systems share a 20 SEER2 efficiency rating. The ROVSUN outdoor unit is significantly heavier at 250 pounds compared to the Della’s 33.1 pounds, indicating a different internal build. This option suits you if you need balanced cooling for four similar-sized rooms rather than one larger space. It lacks the concealed ducted design of the Della, using standard wall mounts instead.
TOSOT Cosmo 36K BTU Quad Zone
The TOSOT Cosmo offers 21 SEER2 efficiency, which is higher than the Della’s 20 SEER2. You get 36,000 total BTU across four equal 9K units, compared to the Della’s mixed 9K and 18K setup. The TOSOT unit is much heavier at 339 pounds and wider, suggesting a robust compressor for extreme climates. Like the Della, it uses wall-mounted handlers, not concealed ductwork. This choice fits you if you prioritize energy savings and cold-weather performance over the aesthetic benefit of hidden indoor units. The Della retains the advantage of geolocation smart features and a built-in condensate pump for easier installation in attics.
Senville 36k BTU 4-Zone Mini Split
The Senville system delivers 36,000 BTU with four 9K units, offering more total capacity than the Della’s 34,000 BTU. It is designed for cold climates with robust heating capabilities. The outdoor unit is very large at 40x60x48 inches, which is substantially bigger than the Della’s compact 27.5x7.87x19.3 inch unit. Both use wall-mounted indoor handlers. You should choose the Senville if you need maximum heating power in freezing temperatures and have space for a large outdoor condenser. The Della is better for those who want a smaller footprint and concealed ceiling installation with smart app integration.
TURBRO 36k BTU 4-Zone Mini Split
The TURBRO model features Wi-Fi control, which is a specific smart connectivity option compared to the Della’s app and Alexa support. It provides 36,000 BTU with two 12K units and two 9K units, differing from the Della’s three 9K and one 18K configuration. The outdoor unit weighs 332 pounds, which is heavier than the Della’s 33.1 pounds. Both systems use wall-mounted indoor units. You might prefer the TURBRO if you want precise zone management with high-efficiency ratings and do not need concealed ductwork. The Della remains the better choice for hidden installations and lower-profile indoor units that blend into ceilings.
Cozeware 38000 BTU 4-Zone Mini Split
The Cozeware system stands out with a 23 SEER2 efficiency rating, which is significantly higher than the Della’s 20 SEER2. It offers 38,000 BTU total capacity. The outdoor unit is lightweight at 255 pounds and compact, similar in dimensions to the TURBRO but much lighter than the Della’s indoor-focused weight metric. This model is ideal for energy-conscious buyers who want top-tier efficiency. However, it uses wall-mounted handlers, unlike the Della’s concealed ducted design. If you prioritize energy savings and cold-climate operation over the aesthetic of hidden indoor units, the Cozeware is a strong alternative to the Della.
Della 35K BTU 4 Zone Mini Split
The second Della model offers 35,000 BTU with two 12K units and two 9K units, differing from the original’s 9+9+9+18 configuration. It has a lower 19 SEER2 efficiency rating compared to the original’s 20 SEER2. This unit is suitable if you have rooms that require higher individual capacity, such as larger living areas. It retains the same brand reliability and Alexa control. You should pick this alternative if you need more power in two specific zones rather than one large zone. The original Della is better for those who want higher efficiency and a single high-capacity unit for a large open space.
