6 Best Alternatives to the ACiQ Essentials 24000 BTU 230V 17 SEER2 Mini Split (2026)

How each alternative compares

Senville LETO 24K BTU 230V Mini Split

The Senville LETO offers the same 24,000 BTU capacity and 230V power as the ACiQ, making it a direct replacement for large spaces. It differs in physical dimensions, with a more compact indoor unit measuring 33.3 inches wide compared to the ACiQ’s 39.8 inches. While both units target similar room sizes, the Senville model focuses on robust capacity rather than the comprehensive installation kit included with the ACiQ. You get a white finish on both, but the Senville may suit you if wall space is tighter. However, its efficiency and cold-weather performance trail the top SEER2 alternatives, so you might prefer higher efficiency if that is a priority for your specific climate conditions.

Albott 18k BTU 230V Mini Split

The Albott 18k BTU model steps down in capacity from the ACiQ’s 24,000 BTU to 18,000 BTU, targeting medium rooms up to 1250 square feet instead of larger areas. It improves on efficiency with a 19 SEER2 rating compared to the ACiQ’s 17 SEER2, which means lower energy usage for comparable cooling. Both units operate on 230V power. The Albott indoor unit is slightly narrower at 37.8 inches wide versus the ACiQ’s 39.8 inches. You should pick this alternative if you need less cooling power but value higher energy efficiency. The weight is also significantly higher at 151 pounds, which may affect installation logistics compared to the lighter ACiQ unit.

Rellytech 18000 BTU 230V Mini Split

The Rellytech 18000 BTU unit provides 19 SEER2 efficiency, beating the ACiQ’s 17 SEER2 rating for better energy savings in smaller rooms. It shares the 230V power requirement but reduces capacity from 24,000 to 18,000 BTU, making it suitable for spaces under 1250 square feet. The indoor unit is 39.6 inches wide, nearly identical to the ACiQ’s 39.8 inches. You get a similar white finish and compact design. This option is practical if you need better efficiency than the standard 17 SEER2 models but do not require the full cooling output of the ACiQ. It is a straightforward swap for smaller areas where energy costs are a primary concern over maximum cooling capacity.

COSTWAY Blast Pro 18000 BTU 230V

The COSTWAY Blast Pro offers 20 SEER2 efficiency, the highest on this list, surpassing the ACiQ’s 17 SEER2 rating for superior energy savings. It reduces capacity to 18,000 BTU, targeting medium rooms rather than large spaces. Like the ACiQ, it uses 230V power. A key difference is the inclusion of Wi-Fi smart control, which the ACiQ data does not mention. The indoor unit is 35.8 inches wide, narrower than the ACiQ’s 39.8 inches. You should choose this model if you prioritize smart features and energy efficiency over raw cooling power. It is a quiet, efficient choice for buyers who want modern connectivity and lower operating costs in medium-sized rooms.

COSTWAY 24000 BTU 230V Mini Split

The COSTWAY 24000 BTU model matches the ACiQ’s capacity and 230V power, making it a direct alternative for large spaces. It offers 18.5 SEER efficiency, slightly higher than the ACiQ’s 17 SEER2. The indoor unit is wider at 44.5 inches compared to the ACiQ’s 39.8 inches. Both are white, but the COSTWAY emphasizes self-cleaning features and multiple operating modes. You might prefer this if you value those specific functions over the comprehensive installation kit included with the ACiQ. It fits buyers who prioritize performance features and efficiency over the bundled accessories. The weight is significantly lower at 68 pounds, which may simplify handling during installation.

Mountman 12000 BTU 230V Mini Split

The Mountman 12000 BTU unit is designed for smaller rooms up to 750 square feet, significantly less than the ACiQ’s 1500 square foot coverage. It offers 19 SEER2 efficiency, beating the ACiQ’s 17 SEER2 rating. Both use 230V power. The indoor unit is 32.3 inches wide, narrower than the ACiQ’s 39.8 inches. You should pick this alternative if you need less cooling power for a smaller space but still want high efficiency and 230V compatibility. It is a compact, efficient choice that avoids the larger footprint and higher capacity of the ACiQ. This model is ideal for buyers who do not require the full 24,000 BTU output of the other options on this list.
