You might find a higher SEER2 rating for better energy savings or a different voltage requirement for your electrical setup. This guide helps you compare specs to find the system that matches your exact spatial and comfort needs.
Comparing four-zone mini split options
ROVSUN 38000 BTU Quad Zone Mini Split
The ROVSUN 38K BTU model offers four equal 9,000 BTU zones, unlike the Della’s mixed 6K and 24K setup. It provides 20 SEER2 efficiency, which is lower than the Della’s 24 SEER2 rating. This system uses 230V power and weighs 250 pounds. You get balanced airflow across all rooms rather than targeted high-capacity cooling. Choose this if you need uniform temperature control in four similar-sized spaces and do not require the highest efficiency tier or extreme cold heating down to -22°F. It is a practical choice for even distribution over maximum power savings.
TOSOT Cosmo 36K BTU Quad Zone
The TOSOT Cosmo 36K BTU unit features four equal 9,000 BTU zones and 21 SEER2 efficiency. It operates down to -22°F, matching the Della’s cold-weather capability. However, it has lower total cooling capacity at 36,000 BTU compared to the Della’s 48,000 BTU. The TOSOT weighs 339 pounds and uses Wi-Fi for control. You trade total BTU output and higher SEER2 for equal zone sizing. Pick this if your rooms are identical in size and you need reliable sub-zero heating. It is less suitable for large open areas requiring high individual zone capacity.
Senville 36k BTU 4-Zone Mini Split
The Senville 36K BTU system provides four 9,000 BTU zones with smart control features. It lacks the high 24 SEER2 efficiency of the Della, focusing instead on cold-weather performance and individual zone management. The Senville weighs significantly more at 60 inches in height. You get reliable multi-room control but with lower total capacity and efficiency. This option suits users who prioritize smart connectivity and balanced 9K zones over maximum energy savings or extreme cold operation down to -22°F. It is a solid choice for standard multi-room homes needing consistent temperature control.
TURBRO 36k BTU 4-Zone Mini Split
The TURBRO 36K BTU model offers Wi-Fi control and four zones with a 9+9+12+12 BTU configuration. It uses 230V power and weighs 332 pounds. Efficiency is not specified, but it lacks the Della’s 24 SEER2 rating and -22°F heating capability. You get strong smart features and moderate climate performance. Choose this if Wi-Fi control is your priority and you do not need extreme cold operation. It is better for homes where smart connectivity matters more than maximum efficiency or sub-zero heating reliability. The mixed zone sizes offer flexibility similar to the Della.
Cozeware 38000 BTU 4-Zone Mini Split
The Cozeware 38K BTU unit delivers 23 SEER2 efficiency, which is close to the Della’s 24 SEER2 rating. It provides four zones with smart controls and quiet operation. The Cozeware weighs 255 pounds and uses a similar outdoor unit size. You get high energy efficiency and smart features but with lower total cooling capacity at 38,000 BTU. This model is ideal for large spaces where energy savings and quiet operation are key. It is a strong alternative if you want near-top efficiency without the Della’s specific soft airflow design or mixed zone configuration.
Della 35K BTU 4 Zone Mini Split
The Della 35K BTU 4-Zone model offers 19 SEER2 efficiency and Alexa integration. It has a 9+9+12+12 BTU configuration and weighs less than the larger 48K unit. You get cold-weather heating and smart voice control but with lower efficiency and capacity. This model suits buyers who prioritize Alexa compatibility and moderate climate performance over maximum energy savings. It is a good choice if you need smart control and reliable heating but do not require the highest SEER2 rating or extreme cold operation down to -22°F. It offers a balanced mix of features for multi-zone comfort.
