This setup works well for homes needing separate temperature management. However, you might want different specs or brands. Some users prefer single-zone comfort or equal zone distribution. Others seek Alexa integration or softer airflow.
This list covers 6 alternatives worth a look. Each option shares key features with the original, such as high efficiency ratings and smart connectivity. You will find dual-zone and tri-zone models with varying BTU outputs. Some units offer gentle soft airflow for draft-free cooling. Others provide balanced performance for equal-sized rooms. All selections match the core needs of multi-zone climate control. You can compare voltage, size, and smart features to find the right fit. These choices ensure you get the specific capabilities you require.
How these alternatives compare
DELLA Optima 23K BTU Soft Airflow
The DELLA Optima targets single-zone comfort rather than multi-room distribution. It delivers 23,000 BTU in one unit, which simplifies installation for a single large space. Unlike the COSTWAY tri-zone model, you do not get separate indoor units for different rooms. It shares the 23 SEER2 efficiency rating and 230V voltage. The DELLA includes Alexa compatibility alongside Wi-Fi, offering slightly broader voice control options. Its indoor unit is wider at 43.2 inches, which may affect placement on your wall. Choose this if you need draft-free cooling in one area and do not require zone separation.
COSTWAY 28K Dual Zone 23 SEER2
This COSTWAY dual-zone model focuses on high capacity for two large rooms. It splits power into two 18,000 BTU units, totaling 36,000 BTU. This exceeds the 24,000 BTU total of the tri-zone original. You give up the ability to control three distinct spaces, but gain more cooling power per zone. It maintains the 23 SEER2 efficiency and 230V requirement. Wi-Fi control remains standard. The outdoor unit is slightly smaller in width at 31.9 inches. Pick this alternative if you have two large rooms that need intense cooling and do not need a third zone.
YITAHOME Tri-Zone 24K BTU Mini Split
The YITAHOME tri-zone unit offers balanced 24,000 BTU distribution across three zones. It shares the 23 SEER2 efficiency and 230V voltage with the COSTWAY original. A key difference is the smart control ecosystem; this model adds Alexa support to its Wi-Fi connectivity. The indoor units are more compact, measuring 31 inches wide and 11.5 inches high. This slimmer profile might fit tighter wall spaces better than the COSTWAY’s larger chassis. It is ideal if you want three zones with broader voice assistant integration and a smaller indoor footprint.
COSTWAY 24k 2-Zone 23 SEER2
This COSTWAY dual-zone split provides 9,000 BTU and 18,000 BTU for two rooms. It matches the 23 SEER2 efficiency and 230V electrical requirement of the tri-zone original. You sacrifice the third zone for a more flexible capacity split, which suits homes with one large and one small room. The outdoor unit dimensions are identical to the tri-zone model at 34.7 inches wide. Wi-Fi control is included for remote management. Select this if you need high efficiency for two specific rooms with uneven size requirements rather than three equal zones.
YITAHOME 24K BTU 3 Zone Mini Split
The YITAHOME 24K 3-Zone Mini Split delivers multi-room climate control with smart features. It operates at 23 SEER2 and 230V, matching the original’s efficiency. This model includes both Wi-Fi and Alexa support, expanding your control options beyond the COSTWAY’s Wi-Fi only setup. The indoor units are compact, measuring 31 inches wide and 11.5 inches high. This design may be preferable for rooms with limited wall space. It is a strong choice if you prioritize voice assistant integration and a smaller indoor unit profile while maintaining three-zone capability.
YITAHOME 24K BTU 3-Zone 23 SEER2
This YITAHOME 24K 3-Zone model provides balanced cooling for three equal spaces. It shares the 23 SEER2 efficiency rating and 230V voltage with the COSTWAY original. The main advantage is the inclusion of Alexa voice control alongside Wi-Fi. The indoor units are slimmer, at 31 inches wide and 11.5 inches high, which offers a different aesthetic and fit compared to the COSTWAY’s larger indoor chassis. It is suitable for buyers who need three distinct zones with equal capacity and want the convenience of voice commands for daily adjustments.
