You might be looking for tosot 12 alternatives because the TOSOT Aoraki 12,000 BTU Mini Split has specific strengths that do not match every home. This unit offers a high 24.5 SEER2 efficiency rating and operates in extreme cold down to -20°F. It also supports optional ERV integration for fresh air ventilation. These specs make it ideal for small spaces in harsh climates where energy savings and cold-weather heating are priorities.
However, you may need a different capacity, voltage, or smart feature set. Some buyers prefer higher BTU outputs for larger rooms, while others prioritize Wi-Fi connectivity or a lower price point. The alternatives listed here were chosen because their specifications overlap with the original TOSOT model. We compared key metrics like SEER2 ratings, cooling capacity, and voltage compatibility to ensure these options provide similar core performance. This guide helps you find a unit that fits your specific spatial and efficiency requirements without relying on the TOSOT Aoraki.
How alternatives compare to TOSOT
Rellytech 18000 BTU 230V Mini Split
The Rellytech 18,000 BTU model offers 50% more cooling capacity than the TOSOT Aoraki. It targets larger rooms that the 12,000 BTU unit cannot handle effectively. Its efficiency rating is 19 SEER2, which is lower than the TOSOT’s 24.5 SEER2. You trade some energy savings for greater power. The indoor unit is wider at 39.6 inches, requiring more wall space. It runs on 230V like the TOSOT. Choose this if you need stronger cooling for a bigger area and do not need the highest possible efficiency rating.
YITAHOME 12000 BTU 230V Mini Split
The YITAHOME 12,000 BTU unit matches the TOSOT in cooling capacity but uses a lower 17 SEER2 efficiency rating. It includes Wi-Fi smart control, which the TOSOT data does not confirm. The indoor unit is narrower at 31.2 inches wide. It weighs only 21.1 pounds, making it lighter than the TOSOT’s 44.5 pounds. This model suits users who prioritize smart home integration and budget over peak energy efficiency. It is a practical choice for small rooms where Alexa compatibility matters more than the TOSOT’s extreme cold performance or ventilation options.
COSTWAY 24000 BTU 230V Mini Split
The COSTWAY 24,000 BTU model provides double the cooling power of the TOSOT Aoraki. It is designed for larger spaces that require 24,000 BTU. Its efficiency is 18.5 SEER, which is significantly lower than the TOSOT’s 24.5 SEER2. You gain substantial cooling capacity but lose energy efficiency. The unit is wider at 44.5 inches. It operates on 208-230V, similar to the TOSOT. Pick this alternative if you have a large room that needs high output and are willing to accept lower efficiency ratings for that increased power.
Senville LETO 24K BTU 230V Mini Split
The Senville LETO 24,000 BTU unit offers high cooling capacity for larger spaces, unlike the TOSOT’s 12,000 BTU limit. It runs on 230V power. The indoor unit dimensions are distinct, with a width of 12.6 inches and a height of 27.6 inches. It weighs only 11.7 pounds, which is much lighter than the TOSOT. This model fits users who need 24,000 BTU for effective temperature management in big rooms. It is a strong option for larger areas where high output is necessary, even though it does not match the TOSOT’s specific efficiency or cold-climate certifications.
ROVSUN 12000 BTU 230V Mini Split
The ROVSUN 12,000 BTU model matches the TOSOT in cooling capacity but offers 20 SEER2 efficiency, which is lower than the TOSOT’s 24.5 SEER2. It includes Wi-Fi smart control for remote management. The indoor unit is 31.9 inches wide and weighs 70 pounds. It is suitable for users who want smart connectivity in a 12,000 BTU package. Choose this if you prioritize smart home features and moderate efficiency over the TOSOT’s higher energy savings and extreme cold weather performance. It provides a solid balance of capacity and modern control options.
COSTWAY Blast Pro 18000 BTU 230V

Frequently asked questions
Which mini split has the highest SEER2 rating among these alternatives?
The TOSOT Aoraki 12,000 BTU Mini Split leads with a 24.5 SEER2 efficiency rating. This high number indicates lower energy consumption for cooling. If you prioritize efficiency over raw cooling power, this model is the top choice. Other options like the Rellytech and COSTWAY Blast Pro offer 19 to 20 SEER2, which is good but lower than the TOSOT.
What is the difference between 12,000 BTU and 18,000 BTU units?
The main difference is cooling capacity. A 12,000 BTU unit, like the TOSOT Aoraki or YITAHOME, suits smaller rooms. An 18,000 BTU model, such as the Rellytech or COSTWAY Blast Pro, provides 50% more cooling power. You should choose the higher capacity if you are cooling a larger space that a 12,000 BTU unit cannot handle effectively.
Do these mini splits require 230V power?
Yes, all listed alternatives operate on 230V power. This includes the TOSOT Aoraki, Rellytech, YITAHOME, COSTWAY, Senville, and ROVSUN models. Using the correct voltage is essential for proper installation and performance. You will need a dedicated 230V circuit for any of these units to function safely and efficiently.
Which models support Wi-Fi smart control?
Three models feature Wi-Fi smart control: the YITAHOME 12,000 BTU, the ROVSUN 12,000 BTU, and the COSTWAY Blast Pro 18,000 BTU. These units allow you to manage settings remotely. If you want Alexa compatibility or app-based control, these are your best options among the listed alternatives.
Which alternative is best for larger rooms?
For larger rooms, you should look at the 18,000 BTU or 24,000 BTU models. The Rellytech 18,000 BTU and COSTWAY Blast Pro 18,000 BTU offer strong capacity. The COSTWAY 24,000 BTU and Senville LETO 24K BTU provide even more power. These units are designed for spaces that need more than 12,000 BTU for effective temperature management.
Are there any budget-friendly options with smart features?
The YITAHOME 12,000 BTU Mini Split is positioned as the best budget option. It includes Wi-Fi smart control and operates quietly. While its 17 SEER2 rating is lower than the TOSOT, it fits buyers who prioritize cost and smart features over peak efficiency. It is a practical choice for small rooms.
How do the dimensions of indoor units compare?
Indoor unit sizes vary significantly. The Senville LETO is notably narrower at 12.6 inches wide. The COSTWAY 24,000 BTU is the widest at 44.5 inches. Most 12,000 BTU units, like the YITAHOME and ROVSUN, are around 31 to 32 inches wide. Check these dimensions to ensure the unit fits your wall space.
Which unit is best for cold-weather heating performance?
The TOSOT Aoraki is noted for its cold-climate performance, operating down to -20°F. While other units like the COSTWAY Blast Pro also prioritize heating, the TOSOT data specifically highlights this strength. If you live in a cold region and need reliable heating, the TOSOT Aoraki is a strong candidate among these alternatives.
