Temprium 12000 BTU Mini Split Alternatives: 6 Similar Picks Compared

Comparing Mini Split Alternatives

COSTWAY Blast Pro 18000 BTU 230V

The COSTWAY Blast Pro delivers 18,000 BTU of cooling and heating power, which is significantly higher than the Temprium’s 12,000 BTU capacity. Both units operate on 230V power and share a 20 SEER2 efficiency rating. The COSTWAY model is larger, measuring 35.8 inches wide compared to the Temprium’s 30 inches. It also weighs less at 20.9 pounds versus 40.8 pounds. This higher output makes the COSTWAY better for larger rooms that need more power. However, it is not a direct replacement for spaces sized for 12,000 BTU. If you need extra cooling capacity and have the electrical setup, this is a strong option.

ROVSUN 12000 BTU 230V Mini Split

The ROVSUN RV12T2 offers the same 12,000 BTU capacity and 230V power as the Temprium, but it weighs 70 pounds, which is much heavier than the Temprium’s 40.8 pounds. Both units share a 20 SEER2 efficiency rating and include Wi-Fi smart control. The ROVSUN model is slightly wider at 31.9 inches compared to the Temprium’s 30 inches. It provides similar quiet performance and smart features for medium-sized rooms. If you prefer a heavier, robust unit with established smart connectivity, this is a viable alternative. The Temprium remains lighter and easier to handle during installation.

ROVSUN 12000 BTU 230V Mini Split

This ROVSUN model matches the Temprium with 12,000 BTU capacity, 230V power, and a 20 SEER2 efficiency rating. It is significantly heavier at 70 pounds compared to the Temprium’s 40.8 pounds. The dimensions are also larger, with a width of 31.9 inches versus 30 inches. Unlike the Temprium, this model does not list Wi-Fi or smart home integration in its attributes. It is a reliable choice for homeowners who want efficient heating and cooling without smart features. If you prefer simplicity and do not need app control, this unit offers similar core performance at a potentially lower complexity level.

TOSOT 18,000 BTU WiFi Mini Split

The TOSOT unit provides 18,000 BTU of capacity, which is 50% more than the Temprium’s 12,000 BTU. Both operate on 230V power and share a 20 SEER2 efficiency rating. The TOSOT includes Wi-Fi and Alexa compatibility, similar to the Temprium’s smart features. It is much larger, measuring 37.3 inches in height and 23.3 inches in width, compared to the Temprium’s 11.6-inch height and 30-inch width. This model is better suited for large rooms that need robust cooling and heating. If you require higher output and have the space for a larger indoor unit, this is a solid choice over the Temprium.

Della Vario 9000 BTU Mini Split

The Della Vario offers 9,000 BTU of capacity, which is lower than the Temprium’s 12,000 BTU. Both units operate on 230V power and share a 20 SEER2 efficiency rating. The Della Vario includes Wi-Fi and Alexa smart control, matching the Temprium’s connectivity. It is lighter at 19.8 pounds compared to the Temprium’s 40.8 pounds. The dimensions are similar, with a width of 31.9 inches and height of 11.5 inches. This model is better for smaller rooms that do not need the Temprium’s higher cooling power. If you are cooling a smaller space and want a lighter unit with smart features, this is a suitable alternative.

ROVSUN 28000 BTU Tri-Zone Mini Split

The ROVSUN Tri-Zone system provides 28,000 BTU total capacity across three zones, which is vastly different from the Temprium’s single 12,000 BTU unit. Both operate on 230V power and share a 20 SEER2 efficiency rating. The Tri-Zone model includes Wi-Fi smart control. It is significantly larger and heavier, weighing 179 pounds and measuring 38.5 inches wide. This system is designed for multi-room climate control with separate settings for each zone. If you need to manage the temperature in three distinct areas with one outdoor unit, this is the right choice. It is not a direct replacement for a single-room 12,000 BTU setup.
