How these alternatives compare
Della 17K BTU 2-Zone Concealed Mini Split
The Della 17K BTU concealed unit prioritizes hidden aesthetics over raw cooling power. It features a dual-zone setup with two 12,000 BTU indoor units, totaling 17,000 BTU, which is significantly lower than the TOSOT 30k’s 30,000 BTU capacity. This model is much smaller, weighing only 33.1 pounds compared to the TOSOT’s 263 pounds. It offers the same 21 SEER2 efficiency rating but is designed for ceiling installations where visibility matters. You should choose this alternative if you have smaller spaces and have already planned for professional installation of concealed ductwork. It sacrifices the high capacity needed for large areas to fit into tight architectural spaces.
TOSOT 33,600 BTU 21 SEER2 Mini Split
The TOSOT 33,600 BTU Wi-Fi model focuses on smart connectivity and larger room coverage. It delivers 36,000 BTU of cooling, which is higher than the TOSOT 30k’s 30,000 BTU output. This unit operates on 230V power, whereas the TOSOT 30k typically uses standard residential voltage configurations. It weighs 181 pounds, making it lighter than the 263-pound TOSOT 30k outdoor unit. The primary advantage is the dedicated Wi-Fi control, offering potentially more robust smart features than the Gree+ app used by the Cosmo series. Select this option if you need stronger cooling for a single large zone or prefer advanced Wi-Fi integration over multi-zone flexibility.
ROVSUN 38000 BTU Dual Zone Mini Split
The ROVSUN 38,000 BTU dual-zone unit provides substantial cooling capacity for larger spaces. It offers 35,000 BTU and 24,000 BTU indoor units, totaling 38,000 BTU, which exceeds the TOSOT 30k’s 30,000 BTU total. However, it has a lower efficiency rating of 20 SEER2 compared to the TOSOT’s 21 SEER2. The outdoor unit is wider at 42.3 inches but lighter at 222 pounds. It runs on 230V power. You should pick this alternative if you prioritize maximum cooling power and heat pump versatility over energy savings. It is less efficient but offers more raw capacity for dual zones with unequal size requirements.
DELLA 18K BTU Dual Zone Mini Split
The Della 18K BTU dual-zone mini split is the most efficient option on this list with a 22 SEER2 rating. It provides 18,000 BTU total cooling, split between a 7,000 BTU and a 12,000 BTU indoor unit. This is far less capacity than the TOSOT 30k’s 30,000 BTU. The unit is extremely lightweight at 16.5 pounds and compact in size. It includes smart home features for remote control. Choose this alternative if you are cooling two small rooms and prioritize top-tier energy efficiency over high cooling output. It sacrifices capacity for superior efficiency and a minimal physical footprint.
Senville Dual Zone 28000 BTU Mini Split
The Senville 28,000 BTU dual-zone mini split offers strong independent room control with two 12,000 BTU indoor units. It provides 28,000 BTU of total cooling, slightly less than the TOSOT 30k’s 30,000 BTU. The outdoor unit is compact, measuring 9.18 inches wide and weighing significantly less than the TOSOT’s 263 pounds. It includes smart connectivity for remote management. This model is suitable for buyers who value smart features and efficient voltage operation over maximum SEER2 ratings. Select this alternative if you need reliable dual-zone cooling for moderate-sized spaces and prefer a smaller outdoor footprint.
Della 28K BTU Dual Zone Mini Split
The Della 28K BTU dual-zone mini split offers efficient cooling for two distinct rooms with a total capacity of 28,000 BTU. It has a 20 SEER2 rating, which is lower than the TOSOT 30k’s 21 SEER2. The unit includes a line set kit for easier installation. It weighs 16.5 pounds, making it much lighter than the TOSOT 30k’s 263 pounds. The indoor units are 12,000 BTU and 18,000 BTU.
