How these alternatives compare
Gree 30k BTU Quad-Zone Multi21+
This Gree model also offers quad-zone control and 21 SEER2 efficiency, matching the original’s multi-zone flexibility. The key difference is capacity. It provides 30,000 BTU total, split into smaller units: three 9,000 BTU heads and one 12,000 BTU head. The original delivers a massive 42,000 BTU in a single floor console. If you need less total cooling or prefer multiple smaller indoor units over one large console, this is a better fit. It retains the G10 inverter technology for steady temperatures. Choose this if your space is smaller or requires zoned distribution rather than a single high-output unit.
Rellytech 18k BTU 21 SEER2 Mini Split
This Rellytech unit drops the multi-zone capability entirely for a single 18,000 BTU system. It keeps the 21 SEER2 efficiency rating and 230V power requirement, ensuring similar energy performance. The main trade-off is capacity. You get less than half the cooling power of the 42,000 BTU original. However, it adds Wi-Fi smart control, which the original data does not specify. It is also lighter and more compact. Pick this if you only need to condition one medium-sized room. It is a simpler, more affordable solution for single-zone needs without the complexity of multi-zone distribution boxes or line sets.
COSTWAY 9000 BTU Mini Split 21 SEER2
This COSTWAY model is a single-zone unit with only 9,000 BTU of cooling capacity. It shares the 21 SEER2 efficiency and 230V voltage with the original. The difference is scale. It is designed for small rooms, not large spaces. It includes Wi-Fi smart control, adding remote management capabilities not listed for the original. Its physical size is significantly smaller and lighter. Choose this if you need to cool a small area like a bedroom or office. It gives up the high output and multi-zone flexibility of the original. It is a practical choice for smaller spaces where 42,000 BTU would be excessive and inefficient.
TOSOT 33,600 BTU 21 SEER2 Mini Split
The TOSOT unit offers 33,600 BTU, which is less than the original’s 42,000 BTU but still substantial for large rooms. It matches the 21 SEER2 efficiency and 230V power. It adds Wi-Fi smart control for remote operation. The original is a multi-zone floor console, while this is a single-zone wall-mounted system. You trade multi-zone flexibility for a simpler single-unit setup. This model is heavier and larger than smaller competitors. Select this if you need high cooling power for a large single room. It suits users who want strong performance and smart features without managing multiple indoor zones or complex installation requirements.
Della Vario 24K BTU 21 SEER2
This Della unit provides 24,000 BTU, roughly half the capacity of the original 42,000 BTU model. It maintains the 21 SEER2 efficiency and 230V power. It includes Wi-Fi and Alexa voice control, offering smart integration not specified for the original. It is a single-zone system, unlike the quad-zone original. This model is ideal for medium-sized spaces. It gives up the ability to control four separate areas. Choose this if you need strong cooling for one large room and value voice control. It is a balanced option for users who do not need multi-zone flexibility but want efficient, smart-controlled comfort.
COSTWAY 12,000 BTU 21 SEER2 Mini Split
This COSTWAY model is a single-zone unit with 12,000 BTU capacity. It shares the 21 SEER2 efficiency and 230V power with the original. The capacity is much lower, suitable for small rooms up to 750 square feet. It lacks the multi-zone capability and high output of the original. It is lightweight and compact. Pick this if you need basic cooling and heating for a single small room. It offers a straightforward, no-frills solution. You give up the extensive coverage and zone management of the original. It is a practical choice for smaller spaces where a high-capacity, multi-zone system would be overkill and unnecessarily complex.
