Who it fits
Good fit for
You should choose this system if you need to condition two distinct areas, such as a bedroom and a living room. The 24,000 BTU output fits homes up to 1,300 square feet. The high SEER rating appeals to those who want to reduce electricity usage. The dual-zone design allows you to set different temperatures for each room. This setup is ideal for homes where central air is absent or insufficient for specific zones.
Who should skip it
Skip this model if you only need to cool a single room. The dual-zone design requires two indoor units and separate line sets, which adds complexity and cost if you only have one space. You might also look elsewhere if you need built-in Wi-Fi, as the kit is sold separately. The system is best for larger open areas or two adjacent rooms rather than small, isolated spaces.
Verdict: The Gree Multi21+ offers solid dual-zone performance with high efficiency for medium-sized homes. It is a practical choice for managing temperature in two separate areas effectively.
Key specs explained for this unit
Cooling Capacity: 24,000 BTU
This rating shows the total cooling power of the outdoor unit. It drives two indoor heads, typically sized at 9,000 and 12,000 BTU. You get combined output for multiple rooms. Compare this total to your square footage needs. Larger spaces require higher BTU numbers. This capacity suits medium-sized homes or open layouts.
Efficiency Rating: 21 SEER
Seasonal Energy Efficiency Ratio measures cooling output per watt-hour. A 21 SEER rating indicates strong energy performance. Higher numbers mean lower electricity bills over time. You save more compared to units with lower SEER values. Check this spec when comparing long-term operating costs. It reflects how efficiently the inverter compressor runs during cooling cycles.
Coverage Area: 800 - 1,300 ft2
This range estimates the floor space the system can effectively condition. It assumes standard ceiling heights and typical insulation. You should match this area to your total living space. Smaller rooms may need individual adjustments. Larger areas might require supplemental units. Verify your square footage before purchasing to ensure adequate comfort.
Number of Zones: Dual-Zone
Dual-zone means one outdoor unit connects to two indoor heads. You control temperatures in each room separately. This allows different comfort levels in different spaces. You avoid cooling empty rooms. Compare this to single-zone units that serve only one area. Dual-zone systems offer flexibility for multi-room homes without extra outdoor hardware.
Design and build overview
The Gree Multi21+ uses a compact wall mount layout for its indoor units. According to the listing, this design supports quiet comfort and an attractive appearance in your home. The system relies on G10 inverter-driven compressor technology. This mechanical choice helps reduce outdoor noise while keeping room temperatures steady. It eliminates the harsh starts and stops found in conventional systems. You benefit from smoother operation and consistent airflow.
The unit is powered by eco-friendly R410A refrigerant. It operates on 208/230V voltage, which fits standard residential electrical setups. The total cooling capacity is 24,000 BTU. This power drives two separate zones without needing distribution boxes. The indoor heads typically come in 9,000 and 12,000 BTU sizes. This split allows you to target specific rooms rather than conditioning an entire open floor plan.
You can upgrade the system with a field-installed Wi-Fi kit, though it is sold separately. This accessory allows remote control via smartphone. The listing notes that required line sets are not included. You must purchase 1/4" x 3/8" line sets for each zone. This means you need to prepare the necessary plumbing connections before installation. The compact physical footprint ensures the units fit well in most standard wall spaces without dominating the room visually.
Setup and daily operation details
Installation requires you to purchase line sets separately. You need two sets, each measuring 1/4 inch by 3/8 inch. The system does not include these refrigerant lines in the box. You must connect them to the indoor wall units for proper operation. The unit operates on 208 or 230 volts. You should verify your home’s electrical supply matches these requirements before connecting the power. The G10 inverter-driven compressor manages the power delivery. This technology eliminates harsh starts and stops. It keeps room temperature steady without sudden shifts. You benefit from reduced outdoor noise levels compared to conventional systems. The Multi21+ LIVO wall mount design is compact. This allows for quiet comfort and a clean look in your space. It covers two zones without needing distribution boxes. You can control the system via the included remote. If you want smartphone access, you must buy the field-installed Wi-Fi kit separately. It is not included with the unit. The system uses R410A refrigerant, which is eco-friendly. Daily use involves setting your desired temperature on each zone. The inverter technology adjusts compressor speed to maintain that target. This means less energy waste and more consistent air flow. You do not need to manage complex distribution boxes. The dual-zone setup allows independent control for each room. This feature suits homes where different areas have varying comfort needs. The SEER rating of 21 indicates efficient energy use. This helps keep your electricity bills lower during heavy use periods.
Before you buy this dual zone system
You need to verify your electrical supply before ordering. This unit requires a 208/230V connection. Most standard homes use 120V, so you must confirm your panel can support this voltage. Incorrect wiring will prevent operation.
You must also purchase two line sets separately. Each set measures 1/4 inch by 3/8 inch. These are not included in the box. You need one set for each indoor zone. Factor this cost into your total budget.
Upkeep involves regular filter cleaning. The inverter compressor reduces mechanical stress, which may lower service needs. However, you should still check refrigerant levels annually.
This system suits you if you want to cool two distinct areas with one outdoor unit. It fits well alongside single-zone options if you need broader coverage. Compare its 21 SEER rating against other dual-zone models to ensure it meets your efficiency goals.
Check before you buy
- Confirm your electrical panel supports 208/230V voltage.
- Buy two separate 1/4" x 3/8" line sets.
- Verify both indoor units fit your wall spaces.
- Check if you need the separate Wi-Fi kit.

A 21 SEER2 rating indicates strong energy performance for this dual-zone system. Higher SEER2 values mean the unit uses less electricity to produce the same amount of cooling. You will likely see lower monthly costs compared to less efficient models. This efficiency is driven by the G10 inverter compressor, which adjusts speed rather than cycling on and off.
What is the total cooling capacity of this Gree unit?
The total cooling capacity is 24,000 BTU. This output is split between two indoor zones, typically sized at 9,000 and 12,000 BTU. You get combined output for multiple rooms from a single outdoor unit. This setup allows you to cool distinct areas independently while maintaining a unified energy profile.
Does this mini split require a special electrical connection?
Yes, this unit requires a 230V electrical connection. Most standard homes use 120V, so you must confirm your panel can support this higher voltage. Incorrect wiring will prevent operation. Always verify your electrical supply before ordering to ensure compatibility with the 208/230V requirement listed for the Gree Multi21+.
Are line sets included in the box?
No, the system does not include refrigerant lines in the box. You need to purchase two sets separately, each measuring 1/4 inch by 3/8 inch. These lines must be connected to the indoor wall units for the system to function. Factor these parts into your installation planning and material list.
What is the model number for this Gree dual-zone system?
The model number is MULTI24CLIV201. This identifier corresponds to the Gree Multi21+ 24K BTU Dual-Zone Mini Split. You can use this number to check specific compatibility charts or replacement parts. It helps distinguish this 21 SEER2 unit from other Gree configurations with different capacities or efficiency ratings.
Is this system suitable for cooling two separate rooms?
Yes, this system is designed for two-room cooling with high efficiency. It features a dual-zone configuration that allows independent control of two indoor heads. You can adjust temperatures for each room separately. This makes it ideal for homeowners who prioritize steady comfort in distinct spaces over included smart features.
