6 Best Alternatives to the GREE R32 12 (2026)

How alternatives compare to Gree

ROVSUN 38000 BTU Dual Zone Mini Split

The ROVSUN 38,000 BTU dual zone system serves two large rooms independently, whereas the Gree R32 12 handles only one space. You get 24,000 BTU per zone with this unit, compared to the Gree’s single 12,000 BTU capacity. Efficiency drops to 20 SEER2 from the Gree’s 25 SEER, meaning higher energy use for the same cooling output. You gain the ability to control temperatures in two separate areas with one outdoor unit. This model lacks the smart connectivity features like Google Home or Alexa support found in the Gree. It suits buyers who need robust cooling for multiple large rooms rather than peak energy efficiency or voice control integration.

MRCOOL Easy Pro 24K BTU 230V Wall Mount

The MRCOOL Easy Pro offers 24,000 BTU of cooling power, doubling the capacity of the Gree R32 12. It is designed for larger spaces like offices, while the Gree targets medium-sized single rooms. Both units operate on 230V power and support voice control via smart assistants. The MRCOOL model provides stronger airflow for open areas but does not list a specific SEER rating in the provided data. You trade the Gree’s high 25 SEER efficiency for raw cooling capacity. This option fits users who already have 230V power and need to cool a larger footprint without worrying about precise energy metrics. It is a practical choice for commercial or open-plan residential spaces.

Pioneer Dual Split 18000 BTU 24 SEER2

The Pioneer Dual Split 18,000 BTU system covers two rooms with a single outdoor unit, offering more versatility than the single-zone Gree. It delivers 18,000 BTU total capacity with 24 SEER2 efficiency, which is slightly lower than the Gree’s 25 SEER. You gain the benefit of dual-zone control, allowing independent temperature management in two spaces. This model includes Wi-Fi smart control, similar to the Gree’s Google Home and Alexa connectivity. It is a practical choice for homeowners who need to serve two rooms but prefer a single installation. You sacrifice some peak efficiency for the ability to cool multiple areas simultaneously with one compact system.

Mitsubishi 18k BTU SEER 18 Mini-Split

The Mitsubishi 18,000 BTU unit provides significantly more cooling power than the Gree R32 12, making it suitable for larger spaces up to 750 square feet. It is built for durability in corrosive environments, a feature not highlighted in the Gree’s specifications. The Mitsubishi operates at 18 SEER, which is lower than the Gree’s 25 SEER rating. You gain robust performance and environmental resistance but lose the high energy efficiency and smart connectivity features like voice control. This model is ideal for buyers in coastal or industrial areas who prioritize hardware longevity over smart features. It serves as a heavy-duty alternative for larger rooms where efficiency is secondary to reliability.

Mitsubishi 12,000 BTU 20 SEER Wall Mount

The Mitsubishi 12,000 BTU 20 SEER model matches the Gree in cooling capacity but offers lower efficiency at 20 SEER. It is designed for standard single-room cooling up to 450 square feet, similar to the Gree’s target area. This unit includes installation components like lines and wires, whereas the Gree requires a licensed HVAC contractor and separate lineset purchase. You gain a more complete package for standard installations but lose the higher energy savings and smart connectivity features. This option suits buyers who value included installation parts and dependable single-room performance over peak efficiency or voice control integration. It is a solid choice for straightforward residential applications.

Senville LETO 36k BTU Heat Pump

The Senville LETO 36,000 BTU heat pump delivers triple the cooling capacity of the Gree R32 12, making it suitable for large spaces. It operates on 230V power, compatible with the Gree’s voltage requirements. The Senville model supports smart app management, offering a different approach to control compared to the Gree’s Google Home and Alexa integration. You gain substantial cooling power for expansive areas but lose the high 25 SEER efficiency of the Gree. This unit is best for users who need serious cooling output and prefer app-based management. It serves as a high-capacity alternative for large rooms or open areas where the Gree’s 12,000 BTU output would be insufficient.
