We selected these models because they share high efficiency ratings, such as 21 SEER2, and multi-zone capabilities. You will find options with tri-zone layouts for larger homes or dual-zone units with balanced 12,000 BTU splits. Each alternative offers distinct advantages, from smart connectivity to raw capacity. Review the specs to find the model that matches your specific room sizes and electrical requirements.
Our top pick: Daikin 18,000 BTU 2-Zone Mini Split.
How these alternatives compare
Gree Multi21+ Tri-Zone 24k BTU
The Gree Multi21+ Tri-Zone expands your control from two rooms to three. It offers 24,000 BTU total capacity split into 9K, 9K, and 18K zones. You get the same 21 SEER2 efficiency rating as the Daikin, but with greater flexibility for uneven spaces. This unit runs on 230V power. You must purchase the Wi-Fi kit separately, unlike the Daikin which includes app connectivity out of the box. Choose this if you need to manage three distinct areas and prefer flexible zone sizing over included smart features. It is a strong option for multi-room layouts where independent climate control is essential.
Daikin 24,000 BTU 2-Zone 21SEER2
This Daikin model keeps the 21 SEER2 efficiency but changes the zone balance. It provides 12,000 BTU for each of the two zones, totaling 24,000 BTU. The original system pairs a 9K and 15K unit, which suits mismatched room sizes. This equal split is better for standard residential layouts where two rooms require similar cooling power. It maintains the same brand reliability and smart connectivity via the Daikin One Home app. Select this alternative if your two target spaces are roughly equal in size and you want balanced performance. It offers a more uniform cooling distribution compared to the asymmetric original.
Gree 36K BTU Tri-Zone Wall Mount
The Gree 36K BTU Tri-Zone Wall Mount handles three rooms with a total capacity of 36,000 BTU. It splits this into 9K, 18K, and 18K zones. Like the original, it delivers 21 SEER2 efficiency. You gain significant raw cooling power for larger spaces or multiple bedrooms. However, you move from a two-zone to a three-zone setup. This unit also requires 230V power. It is ideal if you need to cool three separate areas efficiently with a single outdoor unit. The higher capacity supports larger square footage. Choose this if your home has more zones or larger rooms than the original system can comfortably handle.
Gree 36k BTU Dual-Zone Wall Mount
This Gree Dual-Zone unit offers 36,000 BTU total capacity with a 9K and 18K split. It matches the original’s 21 SEER2 efficiency rating but provides double the cooling power. It runs on 230V and is designed for large rooms needing substantial cooling. You give up the balanced two-zone approach for higher capacity in two zones. This system suits buyers who prioritize raw output over fine-tuned zone distribution. It is a robust solution for open-plan areas or larger individual rooms. If you need more than 18,000 BTU of total cooling, this high-capacity dual-zone option delivers the necessary power while maintaining strong energy efficiency.
Gree 36k BTU Dual-Zone Floor Console
The Gree 36k BTU Dual-Zone Floor Console provides 36,000 BTU of cooling in a 9K and 18K configuration. It maintains the 21 SEER2 efficiency rating seen in the original. The key difference is the floor-mounted format. This unit is suitable for spaces where wall space is limited or a low-profile installation is preferred. It offers high capacity for large dual-zone spaces. You trade the wall-mounted indoor units of the Daikin for floor consoles. This alternative is best for buyers who need substantial heating and cooling in a specific footprint. It delivers robust performance in a format that saves wall space.
Rellytech 18k BTU 21 SEER2 Mini Split
The Rellytech 18k BTU Mini Split is a single-zone unit, unlike the two-zone Daikin. It offers 21 SEER2 efficiency and includes Wi-Fi connectivity for smart control. You get reliable performance in extreme temperatures, but you lose the ability to control two separate rooms independently. This unit is ideal for cooling one large space rather than two smaller ones. It runs on 230V power. Choose this if you do not need multi-zone distribution and want strong smart features in a single zone. It is a focused solution for users who prioritize Wi-Fi control and efficiency in a single area over multi-room flexibility.
