Review the specifications below to match the right unit to your home’s specific requirements.
How these alternatives compare
TOSOT Cosmo 36K BTU Quad Zone
The TOSOT Cosmo 36K BTU Quad Zone offers 36,000 BTU of cooling power, which is 6,000 BTU more than the Gree 30k model. It maintains the same 21 SEER2 efficiency rating but includes built-in smart app control, unlike the Gree which requires a separate Wi-Fi kit. This model is slightly wider at 16.8 inches compared to the Gree's 32-inch indoor unit width, though it is taller. You should pick this if you need more raw cooling capacity and want immediate smart connectivity without buying extra accessories.
TOSOT 36k BTU 4 Zone Mini Split
This TOSOT 36k BTU 4 Zone Mini Split also provides 36,000 BTU, exceeding the Gree 30k unit by 6,000 BTU. Like the other TOSOT option, it features 21 SEER2 efficiency and includes smart app management as a standard feature, removing the need for an optional Wi-Fi kit. The indoor unit dimensions match the previous TOSOT model, standing 32.5 inches tall. Choose this alternative if you require higher cooling output for larger zones while still wanting precise, app-based temperature control across all four rooms without additional hardware purchases.
Gree Multi21+ Tri-Zone 24k BTU
The Gree Multi21+ Tri-Zone 24k BTU reduces the zone count from four to three and lowers cooling capacity to 24,000 BTU. It retains the 21 SEER2 efficiency rating and 230V voltage requirement. The indoor unit is similar in width at 32 inches but slightly shorter at 13 inches. This model is ideal if you only need to control three rooms and want to save on upfront capacity costs. You will still need to purchase the Wi-Fi kit separately for smart features, just like with the original Gree 30k model.
Gree 42k BTU Quad-Zone Floor Console
The Gree 42k BTU Quad-Zone Floor Console increases cooling capacity to 42,000 BTU while maintaining four zones and 21 SEER2 efficiency. Its primary difference is the floor console design, which differs from the wall-mounted units in this list. It still requires a separate Wi-Fi kit for smart connectivity. This option suits homes where wall space is limited or where a low-profile unit is preferred for aesthetics. You should choose this if you need significantly more cooling power for large areas without sacrificing multi-zone control.
Gree 42K BTU Dual-Zone Wall Mount
The Gree 42K BTU Dual-Zone Wall Mount offers 42,000 BTU of cooling power, which is 12,000 BTU more than the original. It reduces the zone count from four to two, splitting the capacity into 9K and 18K units. It keeps the 21 SEER2 efficiency rating and 230V voltage. Like the original, it requires a separate Wi-Fi kit for smart control. Pick this alternative if you need high cooling output for fewer, larger rooms and do not need the flexibility of managing four separate zones.
Gree Multi21+ 30k BTU Dual-Zone
The Gree Multi21+ 30k BTU Dual-Zone matches the original cooling capacity of 30,000 BTU but reduces the zone count from four to two. It maintains the 21 SEER2 efficiency rating and 230V voltage requirement. This model splits the capacity into two 12K units. It also requires a separate Wi-Fi kit for smart features. Choose this if you prefer simpler dual-zone control for larger spaces and want to maintain the same high efficiency rating without managing multiple smaller zones.
