How these models differ from COSTWAY
Albott 20K BTU 2 Zone Mini Split
The Albott 20K BTU 2 Zone Mini Split diverges from the COSTWAY by supporting two separate rooms instead of one. It shares the 25 SEER2 efficiency rating and 230V voltage, ensuring similar energy performance. You gain independent climate control for each zone, which the single-zone COSTWAY cannot offer. However, the Albott provides less total cooling capacity at 20,000 BTU compared to the COSTWAY’s 24,000 BTU. It also weighs significantly more at 116 pounds. This model suits buyers who need to manage temperatures in two distinct spaces rather than maximizing power in a single large area.
DELLA CloudAir 12k BTU 25 SEER2
The DELLA CloudAir 12k BTU 25 SEER2 is a compact alternative designed for smaller spaces. It matches the COSTWAY’s 25 SEER2 efficiency and 230V requirement. However, its cooling capacity drops to 12,000 BTU, making it unsuitable for large rooms that the COSTWAY handles well. The indoor unit is narrower at 36.2 inches wide. It includes Wi-Fi and Alexa smart control, similar to the COSTWAY. This unit is ideal for small rooms where quiet operation and precise airflow matter more than raw cooling power. You choose this if your space is under 550 square feet.
TOSOT 24,000 BTU Mini Split
The TOSOT 24,000 BTU Mini Split matches the COSTWAY’s 24,000 BTU cooling capacity and 230V voltage. It offers smart Wi-Fi control for scheduling. The main difference is efficiency. The TOSOT has a 19 SEER2 rating, which is lower than the COSTWAY’s 25 SEER2. This means the TOSOT will consume more energy for the same cooling output. The outdoor unit is also heavier at 173 pounds. You should pick this model if you need high cooling power and do not prioritize maximum energy savings. It is a solid choice for large rooms where efficiency is secondary to capacity.
DELLA Motto 23K BTU 19 SEER2
The DELLA Motto 23K BTU 19 SEER2 provides slightly less cooling capacity at 23,000 BTU compared to the COSTWAY’s 24,000 BTU. It shares the 230V voltage and includes Wi-Fi and Alexa smart control. Its efficiency is lower at 19 SEER2. The unit is lighter at 30.9 pounds and has a narrow indoor profile. It suits users who value smart voice integration and quiet operation over peak efficiency. You might choose this if you need a balance of power and connectivity without the highest efficiency rating. It is a practical option for 230V installations where Alexa compatibility is a priority.
Della Vario 24K BTU 21 SEER2
The Della Vario 24K BTU 21 SEER2 matches the COSTWAY’s 24,000 BTU capacity and 230V voltage. It includes Wi-Fi and Alexa smart control. However, its efficiency is 21 SEER2, which is lower than the COSTWAY’s 25 SEER2. The unit features smart remote sensing and cold-weather heating capabilities. It weighs 36.4 pounds. You should consider this model if you prioritize smart remote sensing and reliable heating in cold conditions over maximum energy efficiency. It is a solid option for buyers who need strong cooling power with added comfort features rather than the highest SEER2 rating.
DELLA Serena CloudAir 23000 BTU
The DELLA Serena CloudAir 23000 BTU offers 23,000 BTU of cooling, slightly less than the COSTWAY’s 24,000 BTU. It shares the 230V voltage and includes Wi-Fi and Alexa smart control. Its efficiency is 22 SEER2, which is lower than the COSTWAY’s 25 SEER2. The unit is designed for comfort-focused cooling in medium rooms up to 1,500 square feet. It weighs 30.9 pounds. You should pick this model if you value gentle airflow and high efficiency over raw capacity. It is a good choice for spaces where comfort and smart features matter more than maximum cooling power.

Which mini split offers the highest efficiency rating available in this list?
The COSTWAY 24000 BTU 25 SEER2 Mini Split and the Albott 20K BTU 2 Zone Mini Split both share the highest efficiency rating of 25 SEER2. This rating indicates superior energy performance compared to other models on the list, such as the TOSOT at 19 SEER2 or the Della Vario at 21 SEER2. Higher SEER2 values generally translate to lower energy consumption for the same cooling output.
Can I control these mini splits using voice assistants like Alexa?
Yes, several models support Alexa voice control. The DELLA CloudAir 12k BTU 25 SEER2, DELLA Motto 23K BTU 19 SEER2, DELLA Vario 24K BTU 21 SEER2, and DELLA Serena CloudAir 23000 BTU all feature Wi-Fi and Alexa compatibility. The COSTWAY and Albott units offer Wi-Fi smart control but do not explicitly list Alexa integration in their provided specifications.
Which model is best for cooling a two-room setup?
The Albott 20K BTU 2 Zone Mini Split is designed for independent climate control in two separate rooms. It features a dual-zone configuration, allowing you to manage temperatures in different spaces simultaneously. This setup differs from single-zone units like the COSTWAY or TOSOT, which are intended for one large area rather than multiple distinct rooms.
Are there options with lower BTU capacity for smaller spaces?
Yes, the DELLA CloudAir 12k BTU 25 SEER2 is a compact option suitable for smaller rooms. It provides 12,000 BTU of cooling power, which is significantly less than the 24,000 BTU units. This model is ideal for spaces up to 550 square feet where high capacity is unnecessary and quiet, efficient operation is a priority.
Which unit provides the strongest cooling capacity for large rooms?
The TOSOT 24,000 BTU Mini Split and the COSTWAY 24000 BTU 25 SEER2 Mini Split both deliver 24,000 BTU of cooling power. The DELLA Vario 24K BTU 21 SEER2 also offers this high capacity. These models are suitable for large rooms that require substantial cooling output, unlike the 12,000 BTU or 20,000 BTU alternatives.
Do all listed models require a 230V electrical connection?
Yes, every model listed in this guide operates on 230V voltage. This includes the COSTWAY, Albott, all DELLA models, and the TOSOT. You must ensure your installation site has a compatible 230V power source. Standard 110V outlets are not suitable for any of these specific mini split units.
Which mini split is best for cold weather heating performance?
The DELLA Vario 24K BTU 21 SEER2 is noted for its cold-weather heating capabilities. It is specifically highlighted for buyers who prioritize smart remote sensing and effective heating in colder temperatures. While other models provide cooling, this unit is singled out for its robust performance in lower ambient conditions.
