How these alternatives compare
Della 28K BTU 3-Zone Mini Split
The Della 28K BTU 3-Zone Mini Split reduces your zone count from four to three, offering 12k BTU per room instead of the COSTWAY’s four 12k units. You gain a smaller outdoor unit footprint, measuring 31.9 inches wide compared to the COSTWAY’s 42.3 inches. Efficiency drops slightly to 20 SEER2, which is lower than the COSTWAY’s 22.5 SEER2 rating. Total cooling capacity is 28,000 BTU versus 35,000 BTU. It retains Wi-Fi and Alexa compatibility for smart control. This model suits you if you need three equal zones and have limited space for the outdoor condenser, accepting lower efficiency for a more compact system.
TURBRO 36k BTU 4-Zone Mini Split
The TURBRO 36k BTU 4-Zone Mini Split increases total capacity to 36,000 BTU, using a 9+9+12+12 BTU configuration rather than the COSTWAY’s four 12k units. This gives you two slightly smaller zones and two standard-sized zones. It matches the COSTWAY’s four-zone layout and Wi-Fi control but does not list a specific SEER2 rating in the provided data. The outdoor unit is narrower at 36.2 inches wide. You should pick this if you need slightly higher total cooling power and are comfortable with uneven zone sizes, prioritizing capacity over the COSTWAY’s balanced four-equal-zone design.
TOSOT 30,000 BTU Tri Zone Mini Split
The TOSOT 30,000 BTU Tri Zone Mini Split reduces your zones from four to three, using a 9+9+12 BTU split. Total capacity drops to 30,000 BTU from the COSTWAY’s 35,000 BTU. However, it offers a higher efficiency rating of 21 SEER2, which is close to the COSTWAY’s 22.5 SEER2 rating. It includes Wi-Fi smart control and is designed for extreme weather resilience. The outdoor unit is significantly narrower at 15.8 inches wide. Choose this if you need fewer zones, value extreme weather performance, and want a compact outdoor unit, accepting lower total cooling power for better weather adaptability.
COSTWAY 36k Dual Zone 23 SEER2
The COSTWAY 36k Dual Zone 23 SEER2 cuts your zone count in half, offering only two zones with 7,000 and 12,000 BTU capacities. Total capacity remains similar at 36,000 BTU. You gain a higher efficiency rating of 23 SEER2 compared to the COSTWAY Quad’s 22.5 SEER2. It retains Wi-Fi control and runs on 230V. This model is best for you if you only need to climate-control two rooms, such as a main living area and one bedroom. You sacrifice the multi-room independence of four zones for higher efficiency and simpler installation in a smaller space.
Della 27K BTU 3-Zone Mini Split
The Della 27K BTU 3-Zone Mini Split reduces your zone count from four to three, using a 9+12+12 BTU configuration. Total capacity drops to 27,000 BTU from the COSTWAY’s 35,000 BTU. It matches the COSTWAY’s Wi-Fi and Alexa smart control features. The outdoor unit is compact at 32.3 inches wide. While the SEER2 rating is not explicitly listed, it is positioned as a solid choice for multi-room setups. Pick this if you need three zones with independent control and have space constraints for the outdoor unit, accepting lower total cooling capacity for a more manageable system.
COSTWAY 30k Tri 3 Zone Mini Split
The COSTWAY 30k Tri 3 Zone Mini Split reduces your zone count from four to three, using a 7+12+18 BTU split. Total capacity is 30,000 BTU, lower than the COSTWAY Quad’s 35,000 BTU. You gain a higher efficiency rating of 23 SEER2 compared to the 22.5 SEER2 in the Quad model. It retains Wi-Fi control and 230V compatibility. This model suits you if you need three zones with varied capacities, such as a large living area and two smaller rooms. You trade one zone and some total cooling power for higher energy efficiency and a more flexible zone distribution.

Frequently asked questions
Which alternative offers the highest efficiency rating?
The COSTWAY 36k Dual Zone model leads with a 23 SEER2 rating. This high efficiency helps reduce energy consumption for two-room cooling. Other options like the TOSOT 30,000 BTU Tri Zone offer 21 SEER2, while the Della 28K provides 20 SEER2. You should choose the 23 SEER2 unit if maximizing energy savings is your primary goal for dual-zone setups.
Are all these mini splits compatible with 230V power?
Yes, every listed alternative requires 230V power. This includes the COSTWAY Quad Zone, Della 28K, TURBRO 36k, TOSOT 30k, COSTWAY Dual Zone, Della 27K, and COSTWAY Tri Zone. You must ensure your electrical infrastructure supports this voltage. Standard 110V outlets are not sufficient for any of these multi-zone systems.
Which models support Alexa voice control?
The Della 28K BTU 3-Zone and Della 27K BTU 3-Zone models support Alexa integration. Both units also feature Wi-Fi connectivity for app control. Other brands like COSTWAY, TURBRO, and TOSOT offer Wi-Fi smart control but do not list Alexa compatibility in their specifications. You should select a Della unit if voice commands are essential.
What is the cooling capacity of the TURBRO 36k model?
The TURBRO 36k BTU 4-Zone Mini Split provides a total of 36,000 BTU. It distributes this capacity across four zones with a 9k+9k+12k+12k BTU configuration.

The COSTWAY 36k Dual Zone Mini Split is the best option for two-room setups. It delivers 7,000 BTU and 12,000 BTU across two zones with 23 SEER2 efficiency. It provides more power than standard dual zones without requiring a full four-zone system. This makes it practical for users who need higher capacity for just two spaces.
How does the Della 27k BTU 3-Zone compare to the 28k model?
The Della 27k BTU 3-Zone offers 9k+12k+12k BTU distribution, while the 28k model provides three equal 12k zones. Both units feature Wi-Fi and Alexa support. The 27k model has a slightly smaller outdoor unit footprint. You should pick the 28k model if you need balanced airflow across three equal-sized rooms.
Which mini split is best for smaller multi-room spaces?
The COSTWAY 30k Tri Zone Mini Split suits smaller multi-room spaces. It offers 7k+12k+18k BTU distribution with 23 SEER2 efficiency and Wi-Fi control. It prioritizes smart features and 230V compatibility over maximum cooling power. This makes it a practical choice for users who do not require the higher capacity of quad-zone systems.
